The -header has a shell part (common to all protocols) and a -protocol-specific part. In Emmy*, :ref:`the protocol-specific part of the -header` contains, most notably, a -priority (a natural number). The consensus operations in a block are called *endorsements*. -These operations can be seen as votes for a given block. -The endorsements included a block at level ``l`` are votes for the block at the previous -level ``l-1``. Each block is signed. - -Before being endorsed, blocks are baked. *Baking* is the action of producing and -signing a block. Corresponding to these two actions of baking and endorsing, at -each level, two lists of slots are being created: a (conceptually) infinite list -of baking slots and a list of ``ENDORSERS_PER_BLOCK`` endorsing slots (the value of ``ENDORSERS_PER_BLOCK`` is one of the :ref:`parameters of the consensus protocol `). The index -of a baking slot is called a *priority*. Each slot is associated to a -participant. A participant can appear several times in both lists. The selection -of participants is at :ref:`random`, independently for -each slot, and is stake based. - -An endorsement for a block at level :math:`\ell` is *valid* if it is signed by -a participant that has an endorsing slot at level :math:`\ell`. The *endorsing -power* of an endorsement is the number of slots the endorser owns at level :math:`\ell`. The endorsing -power of a block is the sum of the endorsing powers of the endorsements it -contains. - - -Minimal block delay function -~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -At the heart of Emmy*, there is the minimal block delay function. This function -serves to compute the minimal time between blocks depending on the current -block's priority `p`, and its endorsing power `e`. Namely, Emmy* defines the -minimal block delay function as follows: - -.. _delaystar: -.. _delaystar_hangzhou: - -.. math:: - delay^*(p, e) = \begin{cases} - md & \text{ if } p = 0 \wedge w \geq \frac{3}{5} te\\ - delay^+(p, e) & \text{ otherwise} - \end{cases} - -where - -- :math:`md` stands for the minimal block delay, -- :math:`te` stands for the "total endorsing power", and -- :math:`delay^+(p, e)` is the minimal block delay function in Emmy+, namely: - -.. math:: - delay^+(p, e) = bd + dp \cdot p + de \cdot max(0, ie - e) - -where - -- :math:`bd` stands for the minimal time between the blocks, -- :math:`dp` stands for "delay per priority", -- :math:`de` stands for "delay per (missed) endorsement", and -- :math:`ie` stands for the "initial endorsing power". - -The delay function serves to determine if a produced block can -be considered as valid. - -Block validity condition -~~~~~~~~~~~~~~~~~~~~~~~~ - -A block with timestamp :math:`t'`, priority :math:`p`, and -endorsing power :math:`e` is *valid* at level :math:`\ell` if: - -- the endorsements in the block are valid for level :math:`\ell-1`, -- it is signed by the baker that has baking slot :math:`p`, and -- :math:`t' \geq t + delay^+(p,e)`, where :math:`t` is the timestamp of the - previous block. - -We note that, by the definition of the delay function, the higher the priority -and the smaller the endorsing power, the longer it takes before the block is -considered as valid. However, if the block has priority 0 and contains endorsements with endorsing -power at least :math:`ie`, then there is no time penalty. - -Emmy* abstractly -~~~~~~~~~~~~~~~~ - -We refer to someone trying to reach consensus by the generic notion of -participant. Emmy* can be described in an abstract manner as -follows: - -- A participant continuously observes blocks and endorsements. -- A participant always adopts the :ref:`fittest`, that - is, the longest (valid) chain it observes. -- A participant that has at least an endorsement slot at level :math:`\ell`, - emits an endorsement for the first block it observes at level - :math:`\ell`. -- A participant produces a block as soon as it is allowed to, that is, as soon - as it can produce a valid block (see the validity condition above). - -Emmy* concretely -~~~~~~~~~~~~~~~~ - -In Tezos, a participant is a :ref:`delegate` that has at least one -:ref:`roll`, and is :ref:`active`. For simplicity we -just refer to participants as delegates (and omit the "active" and "with rolls" -attributes). A delegate plays two roles: - -- that of a **baker**, that is, it creates blocks, or -- that of an **endorser**, that is, it contributes in agreeing on - a block by **endorsing** that block. - - -.. _emmyp_slot_selection: -.. _emmyp_slot_selection_hangzhou: - -To these roles correspond the two types of actions mentioned above, baking and -endorsing. As mentioned above, the baking and endorsing rights of a delegate are -given by its baking, respectively endorsing slots, whose selection is described -:ref:`here`. The mechanism behind baking slots is meant to ensure that -if the delegate whose turn is to bake is for some reason unable to bake, the -next delegate in the list can step up and bake the block. - -.. _emmyp_fitness_and_header: -.. _emmyp_fitness_and_header_hangzhou: - -There are two more notions which are defined abstractly at the level of the -shell and concretized in Emmy*, the :ref:`fitness`, and the -protocol-specific header: - -- the fitness of a block is 1 plus the fitness of the previous block; -- the protocol-specific header of a block has the following fields: - - - ``signature``: a digital signature of the shell and protocol - headers (excluding the signature itself). - - ``priority``: the position in the priority list of delegates - at which the block was baked. - - ``seed_nonce_hash``: a commitment to :ref:`a random number`, used to - generate entropy on the chain. Present in only one out of - ``BLOCKS_PER_COMMITMENT`` (see :ref:`Constants`). - - ``proof_of_work_nonce``: a nonce used to pass a low-difficulty - proof-of-work for the block, as a spam prevention measure. - - ``liquidity_baking_escape_vote``: :ref:`a flag` that requests ending the subsidy. - - -The consensus algorithm is implemented in Tezos in five components: the shell, -the economic protocol, and the three daemons: the baker, the endorser, and the -accuser. - -There are mainly two rules that the shell uses when receiving a new valid block: - -- The shell changes the head of the chain to this new block only if it has a - higher fitness than the current head. -- The shell does not accept a branch whose fork point is in a cycle more than - ``PRESERVED_CYCLES`` in the past. More precisely, if ``n`` is the current - cycle, the last allowed fork point is the first level of cycle - ``n-PRESERVED_CYCLES``. - -The parameter ``PRESERVED_CYCLES`` therefore plays a central role in Tezos: any -block before the last allowed fork level is immutable. - -Finally, the economic protocol provides the rules for when block and -endorsements are valid, as explained above, and defines the economic incentives -of delegates. Finally, the three daemons are responsible for injecting blocks, -endorsements, and respectively accusations (see below) on behalf of delegates. - - -Economic Incentives -~~~~~~~~~~~~~~~~~~~ - -In Emmy*, participation in consensus is rewarded and bad behavior is punished. - -Rewards -^^^^^^^ - -To incentivize participation in the consensus algorithm, delegates are rewarded -for baking and endorsing. The reward for baking a block with priority :math:`p` -and endorsing power :math:`e` is given by the formula -:math:`baking\_reward(p,e)`. The rewards for endorsing a block with priority -:math:`p` and having the corresponding endorsement included in the block is -given by the formula :math:`endorsing\_reward(p,e)`, where :math:`e` is the -endorsement's endorsing power. These reward formulas are as follows: - -.. math:: - baking\_reward(p,e) = \begin{cases} - \frac{e}{te}\cdot \frac{level\_rewards\_prio\_zero}{2} & \mbox{ if } p = 0\\ - \frac{e}{te} \cdot level\_rewards\_prio\_nonzero & \mbox{ otherwise } - \end{cases} - -.. math:: - endorsing\_reward(p,e) = \begin{cases} - baking\_reward(0, e) & \mbox{ if } p = 0\\ - \frac{2}{3} \cdot baking\_reward(0, e) & \mbox{ otherwise } - \end{cases} - -where - -- :math:`level\_rewards\_prio\_zero` and :math:`level\_rewards\_prio\_nonzero` are constants. - -The motivation behind this choice of design is given in the `Carthage blog post -`_. - -Besides the reward for baking, the baker receives all the fees paid for the -transactions included in the baked block. - -Rewards and fees are not distributed immediately, instead they are frozen for a -period of ``PRESERVED_CYCLES``. - -Slashing -^^^^^^^^ - -If a delegate deviates from the consensus rules by baking or endorsing two -different blocks at the same level, we say that a delegate double signs. As a -counter-measure against double signing a *security deposit* is frozen from the -delegate's account. Precisely, each delegate key has an associated security -deposit account. When a delegate bakes or endorses a block the security deposit -is automatically moved to the deposit account where it is frozen for -``PRESERVED_CYCLES`` cycles, after which it is automatically moved back to the -baker's main account. - -The values of the security deposits are ``BLOCK_SECURITY_DEPOSIT`` per block -created and ``ENDORSEMENT_SECURITY_DEPOSIT`` per endorsement slot. - -The evidence for double signing at a given level can be collected by any -:ref:`accuser` and included as an *accusation* operation in a block -for a period of ``PRESERVED_CYCLES``. The inclusion of the accusation leads to -forfeiting the entirety of the security deposits and fees obtained during the -cycle when the double signing was made. Half of this amount is burned, and half -goes to the baker who included the accusation. - -In the current protocol, accusations for the *same* incident can be made several -times after the fact. This means that the deposits and fees for the entire -cycle are forfeited, including any deposit made, or fees earned, after the -incident. Pragmatically, any baker who either double bakes or endorses in a -given cycle should immediately stop both baking and endorsing for the rest of -that cycle. - -.. _cs_constants: -.. _cs_constants_hangzhou: - -Consensus protocol parameters ------------------------------ - -In this section we map the above notation to their corresponding parameter -values. -Note that these parameters are part of the larger set of :ref:`protocol constants `. - -.. list-table:: Mapping - :widths: 55 50 25 - :header-rows: 1 - - * - Notation - - Parameter name - - Parameter value - * - :math:`md` - - ``MINIMAL_BLOCK_DELAY`` - - 30 seconds - * - :math:`bd` - - ``TIME_BETWEEN_BLOCKS[0]`` - - 60 seconds - * - :math:`dp` - - ``TIME_BETWEEN_BLOCKS[1]`` - - 40 seconds - * - :math:`de` - - ``DELAY_PER_MISSING_ENDORSEMENT`` - - 4 seconds - * - :math:`ie` - - ``INITIAL_ENDORSERS`` - - 192 - * - :math:`te` - - ``ENDORSERS_PER_BLOCK`` - - 256 - * - :math:`\frac{level\_rewards\_prio\_zero}{te \cdot 2}` - - ``BAKING_REWARD_PER_ENDORSEMENT[0]`` - - 0.078125 ꜩ - * - :math:`\frac{level\_rewards\_prio\_nonzero}{te}` - - ``BAKING_REWARD_PER_ENDORSEMENT[1]`` - - 0.011719 ꜩ - * - :math:`endorsing\_reward(0,1)` - - ``ENDORSEMENT_REWARD[0]`` - - 0.078125 ꜩ - * - :math:`endorsing\_reward(p,1)` for :math:`p \geq 1` - - ``ENDORSEMENT_REWARD[1]`` - - 0.052083 ꜩ - * - - - ``BLOCK_SECURITY_DEPOSIT`` - - 640 ꜩ - * - - - ``ENDORSEMENT_SECURITY_DEPOSIT`` - - 2.5 ꜩ - -Since blocks are at least ``MINIMAL_BLOCK_DELAY``, that is 30 seconds apart, -and since a cycle has ``BLOCKS_PER_CYCLE``, that is :ref:`8192 -blocks`, a cycle lasts *at least* 2 days, 20 hours, and 16 -minutes, and ``PRESERVED_CYCLES`` cycles, that is 5 cycles, last *at least* 14 -days, 5 hours, and 20 minutes. - -Given that ``MINIMAL_BLOCK_DELAY`` is 30 seconds, :ref:`the minimal block delay -function` says that: - -- if the block is baked at priority 0 and it contains at least 60% of the - endorsements (namely, at least 153 endorsements) then the minimal delay is 30 - seconds; -- otherwise, the higher the priority and the fewer endorsements a block carries - with respect to the 192 endorsements threshold, the longer it takes before it - can be considered valid, where the delay of 60 seconds is incremented by 40 - seconds with each missed priority and with 4 seconds with each missed - endorsement. - - -The value for ``BAKING_REWARD_PER_ENDORSEMENT[0]`` is chosen such that the -inflation from block rewards and endorsement rewards, which is given by -``ENDORSERS_PER_BLOCK`` \* (``ENDORSEMENT_REWARD[0]`` + -``BAKING_REWARD_PER_ENDORSEMENT[0]``) is 80 ꜩ which in turn preserves the 5.51% -annual inflation. - -Since deposits are locked for a period of ``PRESERVED_CYCLES``, one can compute -that at any given time, about ((``BLOCK_SECURITY_DEPOSIT`` + -``ENDORSEMENT_SECURITY_DEPOSIT`` \* ``ENDORSERS_PER_BLOCK``) \* -(``PRESERVED_CYCLES`` + 1) \* ``BLOCKS_PER_CYCLE``) tokens of all staked tokens -should be held as security deposits.

It is meant as a precise reference manual, -not an easy introduction. Even though, some examples are provided at -the end of the document and can be read first or at the same time as -the specification. The document also starts with a less formal -explanation of the context: how Michelson code interacts with the -blockchain. - -Semantics of smart contracts and transactions ---------------------------------------------- - -The Tezos ledger currently has two types of accounts that can hold -tokens (and be the destinations of transactions). - - - An implicit account is a non programmable account, whose tokens - are spendable and delegatable by a public key. Its address is - directly the public key hash, and starts with ``tz1``, ``tz2`` or - ``tz3``. - - A smart contract is a programmable account. A transaction to such - an address can provide data, and can fail for reasons decided by - its Michelson code. Its address is a unique hash that depends on - the operation that led to its creation, and starts with ``KT1``. - -From Michelson, they are indistinguishable. A safe way to think about -this is to consider that implicit accounts are smart contracts that -always succeed to receive tokens, and does nothing else. - -Intra-transaction semantics -~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -Alongside their tokens, smart contracts keep a piece of storage. Both -are ruled by a specific logic specified by a Michelson program. A -transaction to a smart contract will provide an input value and in -option some tokens, and in return, the smart contract can modify its -storage and transfer its tokens. - -The Michelson program receives as input a stack containing a single -pair whose first element is an input value and second element the -content of the storage space. It must return a stack containing a -single pair whose first element is the list of internal operations -that it wants to emit, and second element is the new contents of the -storage space. Alternatively, a Michelson program can fail, explicitly -using a specific opcode, or because something went wrong that could -not be caught by the type system (e.g. gas exhaustion). - -A bit of polymorphism can be used at contract level, with a -lightweight system of named entrypoints: instead of an input value, -the contract can be called with an entrypoint name and an argument, -and these two components are transformed automatically in a simple and -deterministic way to an input value. This feature is available both -for users and from Michelson code. See the dedicated section. - -Inter-transaction semantics -~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -An operation included in the blockchain is a sequence of "external -operations" signed as a whole by a source address. These operations -are of three kinds: - - - Transactions to transfer tokens to implicit accounts or tokens and - parameters to a smart contract (or, optionally, to a specified - entrypoint of a smart contract). - - Originations to create new smart contracts from its Michelson - source code, an initial amount of tokens transferred from the - source, and an initial storage contents. - - Delegations to assign the tokens of the source to the stake of - another implicit account (without transferring any tokens). - -Smart contracts can also emit "internal operations". These are run -in sequence after the external transaction completes, as in the -following schema for a sequence of two external operations. - -:: - - +------+----------------+-------+----------------+ - | op 1 | internal ops 1 | op 2 | internal ops 2 | - +------+----------------+-------+----------------+ - -Smart contracts called by internal transactions can in turn also emit -internal operation. The interpretation of the internal operations -of a given external operation uses a stack, as in the following -example, also with two external operations. - -:: - - +-----------+---------------+--------------------------+ - | executing | emissions | resulting stack | - +-----------+---------------+--------------------------+ - | op 1 | 1a, 1b, 1c | 1a, 1b, 1c | - | op 1a | 1ai, 1aj | 1ai, 1aj, 1b, 1c | - | op 1ai | | 1aj, 1b, 1c | - | op 1aj | | 1b, 1c | - | op 1b | 1bi | 1bi, 1c | - | op 1bi | | 1c | - | op 1c | | | - | op 2 | 2a, 2b | 2a, 2b | - | op 2a | 2ai | 2ai, 2b | - | op 2ai | 2ai1 | 2ai1, 2b | - | op 2ai1 | | 2b | - | op 2b | 2bi | 2bi | - | op 2bi | 2bi1 | 2bi1 | - | op 2bi1 | 2bi2 | 2bi2 | - | op 2bi2 | | | - +-----------+---------------+--------------------------+ - -Failures -~~~~~~~~ - -All transactions can fail for a few reasons, mostly: - - - Not enough tokens in the source to spend the specified amount. - - The script took too many execution steps. - - The script failed programmatically using the ``FAILWITH`` instruction. - -External transactions can also fail for these additional reasons: - - - The signature of the external operations was wrong. - - The code or initial storage in an origination did not typecheck. - - The parameter in a transfer did not typecheck. - - The destination did not exist. - - The specified entrypoint did not exist. - -All these errors cannot happen in internal transactions, as the type -system catches them at operation creation time. In particular, -Michelson has two types to talk about other accounts: ``address`` and -``contract t``. The ``address`` type merely gives the guarantee that -the value has the form of a Tezos address. The ``contract t`` type, on -the other hand, guarantees that the value is indeed a valid, existing -account whose parameter type is ``t``. To make a transaction from -Michelson, a value of type ``contract t`` must be provided, and the -type system checks that the argument to the transaction is indeed of -type ``t``. Hence, all transactions made from Michelson are well -formed by construction. - -In any case, when a failure happens, either total success or total -failure is guaranteed. If a transaction (internal or external) fails, -then the whole sequence fails and all the effects up to the failure -are reverted. These transactions can still be included in blocks, and -the transaction fees are given to the implicit account who baked the -block. - -Language semantics ------------------- - -This specification explains in a symbolic way the computation performed by the -Michelson interpreter on a given program and initial stack to produce -the corresponding resulting stack. The Michelson interpreter is a pure -function: it only builds a result stack from the elements of an initial -one, without affecting its environment. This semantics is then naturally -given in what is called a big step form: a symbolic definition of a -recursive reference interpreter. This definition takes the form of a -list of rules that cover all the possible inputs of the interpreter -(program and stack), and describe the computation of the corresponding -resulting stacks. - -Rules form and selection -~~~~~~~~~~~~~~~~~~~~~~~~ - -The rules have the main following form. - -:: - - > (syntax pattern) / (initial stack pattern) => (result stack pattern) - iff (conditions) - where (recursions) - and (more recursions) - -The left hand side of the ``=>`` sign is used for selecting the rule. -Given a program and an initial stack, one (and only one) rule can be -selected using the following process. First, the toplevel structure of -the program must match the syntax pattern. This is quite simple since -there are only a few non-trivial patterns to deal with instruction -sequences, and the rest is made of trivial patterns that match one -specific instruction. Then, the initial stack must match the initial -stack pattern. Finally, some rules add extra conditions over the values -in the stack that follow the ``iff`` keyword. Sometimes, several rules -may apply in a given context. In this case, the one that appears first -in this specification is to be selected. If no rule applies, the result -is equivalent to the one for the explicit ``FAILWITH`` instruction. This -case does not happen on well-typed programs, as explained in the next -section. - -The right hand side describes the result of the interpreter if the rule -applies. It consists in a stack pattern, whose parts are either -constants, or elements of the context (program and initial stack) that -have been named on the left hand side of the ``=>`` sign. - -Recursive rules (big step form) -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -Sometimes, the result of interpreting a program is derived from the -result of interpreting another one (as in conditionals or function -calls). In these cases, the rule contains a clause of the following -form. - -:: - - where (intermediate program) / (intermediate stack) => (partial result) - -This means that this rule applies in case interpreting the intermediate -state on the left gives the pattern on the right. - -The left hand sign of the ``=>`` sign is constructed from elements of -the initial state or other partial results, and the right hand side -identify parts that can be used to build the result stack of the rule. - -If the partial result pattern does not actually match the result of the -interpretation, then the result of the whole rule is equivalent to the -one for the explicit ``FAILWITH`` instruction. Again, this case does not -happen on well-typed programs, as explained in the next section. - -Format of patterns -~~~~~~~~~~~~~~~~~~ - -Code patterns are of one of the following syntactical forms. - -- ``INSTR`` (an uppercase identifier) is a simple instruction (e.g. - ``DROP``). -- ``INSTR (arg) ...`` is a compound instruction, whose arguments can be - code, data or type patterns (e.g. ``PUSH nat 3``). -- ``{ (instr) ; ... }`` is a possibly empty sequence of instructions, - (e.g. ``IF { SWAP ; DROP } { DROP }``), nested sequences can drop the - braces. -- ``name`` is a pattern that matches any program and names a part of - the matched program that can be used to build the result. -- ``_`` is a pattern that matches any instruction. - -Stack patterns are of one of the following syntactical forms. - -- ``[FAILED]`` is the special failed state. -- ``[]`` is the empty stack. -- ``(top) : (rest)`` is a stack whose top element is matched by the - data pattern ``(top)`` on the left, and whose remaining elements are - matched by the stack pattern ``(rest)`` on the right (e.g. - ``x : y : rest``). -- ``name`` is a pattern that matches any stack and names it in order to - use it to build the result. -- ``_`` is a pattern that matches any stack. - -Data patterns are of one of the following syntactical forms. - -- integer/natural number literals, (e.g. ``3``). -- string literals, (e.g. ``"contents"``). -- raw byte sequence literals (e.g. ``0xABCDEF42``). -- ``Tag`` (capitalized) is a symbolic constant, (e.g. ``Unit``, - ``True``, ``False``). -- ``(Tag (arg) ...)`` tagged constructed data, (e.g. ``(Pair 3 4)``). -- a code pattern for first class code values. -- ``name`` to name a value in order to use it to build the result. -- ``_`` to match any value. - -The domain of instruction names, symbolic constants and data -constructors is fixed by this specification. Michelson does not let the -programmer introduce its own types. - -Be aware that the syntax used in the specification may differ from -the :ref:`concrete syntax `. In particular -some instructions are annotated with types that are not present in the -concrete language because they are synthesized by the typechecker. - -Shortcuts -~~~~~~~~~ - -Sometimes, it is easier to think (and shorter to write) in terms of -program rewriting than in terms of big step semantics. When it is the -case, and when both are equivalents, we write rules of the form: - -:: - - p / S => S'' - where p' / S' => S'' - -using the following shortcut: - -:: - - p / S => p' / S' - -The concrete language also has some syntax sugar to group some common -sequences of operations as one. This is described in this specification -using a simple regular expression style recursive instruction rewriting. - -.. _michelson_type_system: -.. _michelson_type_system_hangzhou: - -Introduction to the type system and notations ---------------------------------------------- - -This specification describes a type system for Michelson. To make things -clear, in particular to readers that are not accustomed to reading -formal programming language specifications, it does not give a -typechecking or inference algorithm. It only gives an intentional -definition of what we consider to be well-typed programs. For each -syntactical form, it describes the stacks that are considered well-typed -inputs, and the resulting outputs. - -The type system is sound, meaning that if a program can be given a type, -then if run on a well-typed input stack, the interpreter will never -apply an interpretation rule on a stack of unexpected length or -contents. Also, it will never reach a state where it cannot select an -appropriate rule to continue the execution. Well-typed programs do not -block, and do not go wrong. - -Type notations -~~~~~~~~~~~~~~ - -The specification introduces notations for the types of values, terms -and stacks. Apart from a subset of value types that appear in the form -of type annotations in some places throughout the language, it is -important to understand that this type language only exists in the -specification. - -A stack type can be written: - -- ``[]`` for the empty stack. -- ``(top) : (rest)`` for the stack whose first value has type ``(top)`` - and queue has stack type ``(rest)``. - -Instructions, programs and primitives of the language are also typed, -their types are written: - -:: - - (type of stack before) -> (type of stack after) - -The types of values in the stack are written: - -- ``identifier`` for a primitive data-type (e.g. ``bool``). -- ``identifier (arg)`` for a parametric data-type with one parameter - type ``(arg)`` (e.g. ``list nat``). -- ``identifier (arg) ...`` for a parametric data-type with several - parameters (e.g. ``map string int``). -- ``[ (type of stack before) -> (type of stack after) ]`` for a code - quotation, (e.g. ``[ int : int : [] -> int : [] ]``). -- ``lambda (arg) (ret)`` is a shortcut for - ``[ (arg) : [] -> (ret) : [] ]``. - -Meta type variables -~~~~~~~~~~~~~~~~~~~ - -The typing rules introduce meta type variables. To be clear, this has -nothing to do with polymorphism, which Michelson does not have. These -variables only live at the specification level, and are used to express -the consistency between the parts of the program. For instance, the -typing rule for the ``IF`` construct introduces meta variables to -express that both branches must have the same type. - -Here are the notations for meta type variables: - -- ``'a`` for a type variable. -- ``'A`` for a stack type variable. -- ``_`` for an anonymous type or stack type variable. - -Typing rules -~~~~~~~~~~~~ - -The system is syntax directed, meaning that it defines a single -typing rule for each syntax construct. A typing rule restricts the type -of input stacks that are authorized for this syntax construct, links the -output type to the input type, and links both of them to the -subexpressions when needed, using meta type variables. - -Typing rules are of the form: - -:: - - (syntax pattern) - :: (type of stack before) -> (type of stack after) [rule-name] - iff (premises) - -Where premises are typing requirements over subprograms or values in the -stack, both of the form ``(x) :: (type)``, meaning that value ``(x)`` -must have type ``(type)``. - -A program is shown well-typed if one can find an instance of a rule that -applies to the toplevel program expression, with all meta type variables -replaced by non variable type expressions, and of which all type -requirements in the premises can be proven well-typed in the same -manner. For the reader unfamiliar with formal type systems, this is -called building a typing derivation. - -Here is an example typing derivation on a small program that computes -``(x+5)*10`` for a given input ``x``, obtained by instantiating the -typing rules for instructions ``PUSH``, ``ADD`` and for the sequence, as -found in the next sections. When instantiating, we replace the ``iff`` -with ``by``. - -:: - - { PUSH nat 5 ; ADD ; PUSH nat 10 ; MUL } - :: [ nat : [] -> nat : [] ] - by { PUSH nat 5 ; ADD } - :: [ nat : [] -> nat : [] ] - by PUSH nat 5 - :: [ nat : [] -> nat : nat : [] ] - by 5 :: nat - and ADD - :: [ nat : nat : [] -> nat : [] ] - and { PUSH nat 10 ; MUL } - :: [ nat : [] -> nat : [] ] - by PUSH nat 10 - :: [ nat : [] -> nat : nat : [] ] - by 10 :: nat - and MUL - :: [ nat : nat : [] -> nat : [] ] - -Producing such a typing derivation can be done in a number of manners, -such as unification or abstract interpretation. In the implementation of -Michelson, this is done by performing a recursive symbolic evaluation of -the program on an abstract stack representing the input type provided by -the programmer, and checking that the resulting symbolic stack is -consistent with the expected result, also provided by the programmer. - -Side note -~~~~~~~~~ - -As with most type systems, it is incomplete. There are programs that -cannot be given a type in this type system, yet that would not go wrong -if executed. This is a necessary compromise to make the type system -usable. Also, it is important to remember that the implementation of -Michelson does not accept as many programs as the type system describes -as well-typed. This is because the implementation uses a simple single -pass typechecking algorithm, and does not handle any form of -polymorphism. - -Core data types and notations ------------------------------ - -- ``string``, ``nat``, ``int`` and ``bytes``: The core primitive - constant types. - -- ``bool``: The type for booleans whose values are ``True`` and - ``False``. - -- ``unit``: The type whose only value is ``Unit``, to use as a - placeholder when some result or parameter is not necessary. For - instance, when the only goal of a contract is to update its storage. - -- ``never``: The empty type. Since ``never`` has no inhabitant, no value of - this type is allowed to occur in a well-typed program. - -- ``list (t)``: A single, immutable, homogeneous linked list, whose - elements are of type ``(t)``, and that we write ``{}`` for the empty - list or ``{ first ; ... }``. In the semantics, we use chevrons to - denote a subsequence of elements. For instance: ``{ head ; }``. - -- ``pair (l) (r)``: A pair of values ``a`` and ``b`` of types ``(l)`` - and ``(r)``, that we write ``(Pair a b)``. - -- ``pair (t{1}) ... (t{n})`` with ``n > 2``: A shorthand for ``pair (t{1}) (pair (t{2}) ... (pair (t{n-1}) (t{n})) ...)``. - -- ``option (t)``: Optional value of type ``(t)`` that we write ``None`` - or ``(Some v)``. - -- ``or (l) (r)``: A union of two types: a value holding either a value - ``a`` of type ``(l)`` or a value ``b`` of type ``(r)``, that we write - ``(Left a)`` or ``(Right b)``. - -- ``set (t)``: Immutable sets of values of type ``(t)`` that we write as - lists ``{ item ; ... }``, of course with their elements unique, and - sorted. - -- ``map (k) (t)``: Immutable maps from keys of type ``(k)`` of values - of type ``(t)`` that we write ``{ Elt key value ; ... }``, with keys - sorted. - -- ``big_map (k) (t)``: Lazily deserialized maps from keys of type - ``(k)`` of values of type ``(t)``. - These maps should be used if you intend to store large amounts of data in a map. - Using ``big_map`` can reduce gas costs significantly compared to standard maps, as data is lazily deserialized. - Note however that individual operations on ``big_map`` have higher gas costs than those over standard maps. - A ``big_map`` also has a lower storage cost than a standard map of the same size, when large keys are used, since only the hash of each key is stored in a ``big_map``. - - A ``big_map`` cannot appear inside another ``big_map``. - See the section on :ref:`operations on big maps ` for a description of the syntax of values of type ``big_map (k) (t)`` and available operations. - -Core instructions ------------------ - -Control structures -~~~~~~~~~~~~~~~~~~ - -- ``FAILWITH``: Explicitly abort the current program. - -:: - - :: 'a : \_ -> \_ - -This special instruction aborts the current program exposing the top -element of the stack in its error message (first rule below).

A contract template defines a set -of basic entrypoints, and its ``parameter`` declaration contains a type -variable for additional entrypoints in some branch of an union type, or -wrapped inside an option type. Letting this type variable be ``never`` in -a particular implementation indicates that the contract template has not -been extended, and turns the branch in the code that processes the -additional entrypoints into a forbidden branch. - -Values of type ``never`` cannot occur in a well-typed program. However, -they can be abstracted in the ``parameter`` declaration of a contract---or -by using the ``LAMBDA`` operation---thus indicating that the corresponding -branches in the code are forbidden. The type ``never`` also plays a role -when introducing values of union or option type with ``LEFT never``, -``RIGHT never``, or ``NONE never``.

This section is to be read as a patch -over the rest of the specification, introducing rules that apply only -in presence of contracts that make use of entrypoints. - -Defining and calling entrypoints -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -Entrypoints piggyback on the constructor annotations. A contract with -entrypoints is basically a contract that takes a disjunctive type (a -nesting of ``or`` types) as the root of its input parameter, decorated -with constructor annotations.

In that case, if there is a constructor annotation -with this name at any position in the nesting of ``or`` types, the -value is automatically wrapped into the according constructors.

Conversely, if the contract is called without specifying an -entrypoint, then it is assumed to be called with the ``default`` -entrypoint. This behaviour makes the entrypoint system completely -transparent to contracts that do not use it. - -This is the case for the previous example, for instance. If a value is -passed to such a contract specifying entrypoint ``default``, then the -value is fed to the contract untouched, exactly as if no entrypoint -was given. - -A non enforced convention is to make the entrypoint ``default`` of -type unit, and to implement the crediting operation (just receive the -transferred tokens). - -A consequence of this semantics is that if the contract uses the -entrypoint system and defines a ``default`` entrypoint somewhere else -than at the root of the parameter type, then it must provide an -entrypoint for all the paths in the toplevel disjunction. Otherwise, -some parts of the contracts would be dead code. - -Another consequence of setting the entrypoint somewhere else than at -the root is that it makes it impossible to send the raw values of the -full parameter type to a contract. A trivial solution for that is to -name the root of the type. The conventional name for that is ``root``. - -Let us recapitulate this by tweaking the names of the previous example. - -``parameter %root (or (or (nat %A) (bool %B)) (or (unit %default) string))`` - -The input values will be wrapped as in the following examples. - -:: - - +------------+---------------------+-----------------------+ - | entrypoint | input | wrapped input | - +------------+---------------------+-----------------------+ - | %A | 3 | Left (Left 3) | - | %B | False | Left (Right False) | - | %default | Unit | Right (Left Unit) | - | %root | Right (Right "bob") | Right (Right "bob") | - +------------+---------------------+-----------------------+ - | not given | Unit | Right (Left Unit) | - | %BAD | _ | failure, contract not | - +------------+---------------------+-----------------------+ - -Calling entrypoints from Michelson -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -Michelson code can also produce transactions to a specific entrypoint. - -For this, both types ``address`` and ``contract`` have the ability to -denote not just an address, but a pair of an address and an -entrypoint.

This is of course also valid for programs not - handwritten but generated by OCaml code, so we are sure that any - manipulated code is type-safe. - - In the end, what remains to be checked is the encoding of the typing - rules as OCaml types, which boils down to half a line of code for - each instruction. Everything else is left to the venerable and well - trusted OCaml. - -- The interpreter is basically the direct transcription of the - rewriting rules presented above. It takes an instruction, a stack and - transforms it. OCaml's typechecker ensures that the transformation - respects the pre and post stack types declared by the GADT case for - each instruction. - - The only things that remain to be reviewed are value dependent - choices, such as we did not swap true and false when - interpreting the IF instruction. - -- The input, untyped internal representation is an OCaml ADT with - only 5 grammar constructions: ``String``, ``Int``, ``Bytes``, ``Seq`` and - ``Prim``. It is the target language for the parser, since not all - parsable programs are well typed, and thus could simply not be - constructed using the GADT. - -- The typechecker is a simple function that recognizes the abstract - grammar described in section X by pattern matching, producing the - well-typed, corresponding GADT expressions. It is mostly a checker, - not a full inferrer, and thus takes some annotations (basically the - input and output of the program, of lambdas and of uninitialized maps - and sets). It works by performing a symbolic evaluation of the - program, transforming a symbolic stack. It only needs one pass over - the whole program. - - Here again, OCaml does most of the checking, the structure of the - function is very simple, what we have to check is that we transform a - ``Prim ("If", ...)`` into an ``If``, a ``Prim ("Dup", ...)`` into a - ``Dup``, etc. diff --git a/docs/hangzhou/plugins.rst b/docs/hangzhou/plugins.rst deleted file mode 100644 index 15505f86800b48a99ea1cc87589bfcb1adefe0ae..0000000000000000000000000000000000000000 --- a/docs/hangzhou/plugins.rst +++ /dev/null @@ -1,54 +0,0 @@ -Protocol plugins -================ - -Protocol plugins implement extra APIs needed by the shell in order to interact with the economic protocol, beyond the one provided by the protocol environment. -This code is not strictly speaking part of the protocol code base, so this is not subject to on-chain governance (see :doc:`voting procedure `), but it is still protocol-dependent, which means that it may vary with different protocols. -For instance, the plugin code for protocol Alpha is located in file :src:`src/proto_alpha/lib_plugin/plugin.ml`. -Thus, a specific version is included in the Octez node for each protocol version (recall that a new release of Octez is usually delivered for each new protocol proposal, see :doc:`../releases/releases`) - -So what kind of features may a protocol plugin provide? -For instance, protocol plugins do not define the context, or restrict the validity of operations. -In turn protocol plugins may, for example: - -- be adjacent enough to the protocol code that it needs to have access to the protocol's internal representations for certain structures: e.g., it has some RPCs that can introspect on the protocol dependent content for certain operations; -- implement some common operations that are customized for each protocol (e.g., :ref:`prevalidator_filters_hangzhou`). - -.. _prevalidator_filters: -.. _prevalidator_filters_hangzhou: - -Prevalidator filters -~~~~~~~~~~~~~~~~~~~~ - -The :ref:`prevalidator component ` of the shell is responsible for disseminating operations over the peer-to-peer network, that may be included in next blocks. -To prevent spam, the prevalidator implements built-in filtering mechanisms that limit to some extent the risk of flooding the network with invalid operations. -However, these selection mechanisms remain rather laxist to protect from DOS attacks. -In particular, a very affordable technique for attackers is based on flooding the network with, valid but useless, zero-fees operations. -This is why an additional and more flexible selection mechanism is included in the Octez node: *prevalidator filters*. - -Prevalidator filters thus serve at further restricting the operations to propapate by the node to the network. -Filters are implemented as a node plugin and a specific filter is delivererd with each protocol version. -When the chain switches to a new protocol, the node installs its corresponding filter, *in lieu of* the filter of the previous protocol. - -The prevalidator filter is based on restricting operations based on their associated fees, to reject "too cheap" or "zero-fees" operations. -However, the filters could also be used to restrict the propagation of consensus operations (e.g. endorsements). - -The filter is tunable by several parameters, whose values can be retrieved and changed by users via the following RPC calls, respectively: - -- ``rpc get /chains//mempool/filter`` -- ``rpc post /chains//mempool/filter`` - -The following parameters can be thus inspected and modified: - -- ``minimal_fees``: type ``int``, default ``100`` -- ``minimal_nanotez_per_gas_unit``: type ``int``, default ``100`` -- ``minimal_nanotez_per_byte``: type ``int``, default ``1000`` -- ``allow_script_failure``: type ``bool``, default ``true`` - -For example, the following command modifies the ``minimal_fees`` parameter (and resets all the other parameters to their default values):: - - tezos-client rpc post /chains/main/mempool/filter with '{ "minimal_fees": "42" }' - -See also: - -- The `mempool plugin API `__ -- MR :gl:`!3118` show defaults in RPC get mempool/filter diff --git a/docs/hangzhou/proof_of_stake.rst b/docs/hangzhou/proof_of_stake.rst deleted file mode 100644 index 595135481c8bc7214b4b2676233cdfdf118a1c74..0000000000000000000000000000000000000000 --- a/docs/hangzhou/proof_of_stake.rst +++ /dev/null @@ -1,209 +0,0 @@ -Proof-of-stake -============== - -Overview --------- - -:doc:`The consensus algorithm ` in Tezos is based on the -*proof-of-stake* mechanism.

The nullifier can only be -produced by the owner of a commitment and it's deterministic so that -everybody can check that it hasn't been already published. -Note however that it is not possible to infer which commitment has -been nullified. -Transactions of this form are privacy preserving and are referred to -as `shielded`, because they reveal neither the amount, the sender nor -the receiver. - -The existing set of transactions is referred to as the `shielded pool`. -Unlike Bitcoin, where everybody can compute the set of unspent -outputs of every user, in Sapling only the owner of a viewing key can -find their outputs and verify that they are not already spent. -For this reason, to an external -observer, the shielded pool is always increasing in size and the more -transactions are added the harder it is to pinpoint the commitments -belonging to a user. - -When we spend a commitment there is some additional information that -we need to transmit to the recipient in order for them to spend the -corresponding output. -This data is encrypted under a symmetric key resulting from a -Diffie-Hellman key exchange using the recipient address and an -ephemeral key. -In principle this `ciphertext` can be transmitted off-chain as it's -not needed to verify the integrity of the pool. For convenience, in -Tezos, it is stored together with the commitment and the nullifier on -chain. - -For reasons of efficiency the commitments are stored in an incremental -`Merkle tree `_ which -allows for compact proofs of membership. The root of the tree is all -that is needed to refer to a certain state of the shielded pool. - -In order to ensure the correctness of a transaction, given that there -is information that we wish to remain secret, the spender must also -generate proofs that various good properties are true. -Thanks to the use of `SNARKs `_ -these proofs are very succinct in size, fast to verify and they don't -reveal any private information. - -This model of transaction adapts elegantly to the case when we need to -mint or burn tokens, which is needed to shield or unshield from a -transparent token. -It suffices to add more values in the outputs than in the inputs -to mint and to have more in inputs than outputs to burn. - -Privacy guarantees -~~~~~~~~~~~~~~~~~~ - -We explained that the shielded pool contains one commitment for each -input (spent or not), and one nullifier for each spent input. -These cryptographic commitments hide the amount and the owner of the -tokens they represent. -Additionally commitments are unlinkable meaning that we can not deduce -which input is spent to create an output. - -It should be noted that the number of inputs and outputs of a -transaction is public, which could help link a class of -transactions. This problem can be mitigated by adding any number of -dummy inputs or outputs at the cost of wasting some space. - -The shielded pool communicates with the public ledger by minting and -burning shielded tokens in exchange for public coins. -Therefore going in and out of the shielded pool is public: we know -which address shielded or unshielded and how much. -We can among other things infer the total number of shielded coins. - -Timing and network information can also help to deduce some private -information. -For example by observing the gossip network we might learn the IP -address of somebody that is submitting a shielded transaction. -This can be mitigated by using `TOR -`_. - -Good practices -~~~~~~~~~~~~~~ - -When blending in a group of people, one should always pay attention to -the size and the variety of the group. - -We recommend two good practices. First, do not originate a second -contract if another one has the same functionalities, it will split -the anonymity set. - -Second, remember that shielding and unshielding are public operations. -A typical anti-pattern is to shield from tz1-alice 15.3 tez, and then -unshield 15.3 tez to tz1-bob. It's fairly clear from timing and -amounts that Alice transferred 15.3 tez to Bob. -To decorrelate the two transfers it is important to change the -amounts, let some time pass between the two and perform the -transactions when there is traffic in the pool. -Similar problems exist in Zcash and they are illustrated in this -introductory `blog post -`_. - -There are a number of more sophisticated techniques to deanonymise -users using timing of operations, network monitoring, side-channels on -clients and analysis of number of inputs/outputs just to mention a few -(`A fistful of Bitcoins -`_ is a good -first read). -We advise users to be familiar with the use of the TOR network and to -use clients developed specifically to protect their privacy. - - -Tezos integration ------------------ - -Michelson: verify update -~~~~~~~~~~~~~~~~~~~~~~~~ - -We introduce two new Michelson types `sapling_state` and -`sapling_transaction`, and two instructions called -`SAPLING_VERIFY_UPDATE` and `SAPLING_EMPTY_STATE` -(see the :doc:`Michelson reference` -for more details). -`SAPLING_EMPTY_STATE` pushes an empty `sapling_state` on the stack. -`SAPLING_VERIFY_UPDATE` takes a transaction and a state and returns an -option type which is Some (updated -state and a balance) if the transaction is correct, None otherwise. -A transaction has a list of inputs, outputs, a signature, a balance, -and the root of the Merkle tree containing its inputs. -The verification part checks the zero-knowledge proofs of all inputs -and outputs of the transaction, which guarantee several properties of -correctness. -It also checks a (randomised) signature associated with each input -(which guarantees that the owner forged the transaction), and the -signature that binds the whole transaction together and guarantees the -correctness of the balance. -All the signatures are over the hash of the data that we wish to sign -and the hash function used is Blake2-b, prefixed with the anti-replay string. -The anti-replay string is the concatenation of the chain id and -the smart contract address. The same string has to be used by the client for -signing. - -Verify_update also checks that the root of the Merkle tree appears in -one of the past states and that the nullifiers are not already -present (i.e. no double spending is happening). -If one of the checks fails the instruction returns None. - -Otherwise the function adds to the new state the nullifiers given with each inputs -and adds the outputs to the Merkle tree, which will produce a new root. -It should be noted that it is possible to generate transactions -referring to an old root, as long as the inputs used were present in -the Merkle tree with that root and were not spent after. -In particular the protocol keeps 120 previous roots and guarantees -that roots are updated only once per block. -Considering 1 block per minute and that each block contains at least -one call to the same contract, a client has 2 hours to have its -transaction accepted before it is considered invalid. - -The nullifiers are stored in a set. The ciphertexts and other relevant -information linked to the commitment of the Merkle tree are -stored in a map indexed by the position of the commitment in the -Merkle tree. - -Lastly the instruction pushes the updated state and the balance as an option -on the stack. - -Example contracts -~~~~~~~~~~~~~~~~~ - -Shielded tez -^^^^^^^^^^^^ - -An example contract to have a shielded tez with a 1 to 1 conversion to -tez is available in the tests of `lib_sapling`. - -Simple Vote Contract -^^^^^^^^^^^^^^^^^^^^ - -One might think to use Sapling to do private voting. -It is possible to adapt shielded transactions to express preferences. -**Note that this is not what Sapling is designed for and it doesn't provide the same properties as an actual private voting protocol.** -A natural naive idea is the following. -Suppose we want a set of users to express a preference for option A or -B, we can generate two Sapling keys with two addresses that are -published and represent the two options. -The contract lets each user create a token which represents one vote -that can then be transferred to address A or B. -Using the published viewing keys everyone can check the outcome of the -vote. -**However note that a transaction can be replayed and we can see the balance of A or B going up. -This system does not offer ballot privacy. -Therefore one should ensure that the vote he is casting cannot be linked to him. -It is possible that the practical situation makes this usable but we recommend in general not to use -it for any important vote.** -Note that using a random elliptic curve element as incoming viewing key allows to generate a -dummy address that cannot be spent. This eases the counting of the votes. -To ensure that the ivk does not correspond to a normal address with spending key, one -can use the Fiat-Shamir heuristic. - - -Fees issue -~~~~~~~~~~ - -We have an additional privacy issue that Z-cash doesn't have. When -interacting with a shielded pool we interact with a smart contract -with a normal transaction and therefore have to pay fees from an -implicit account. -One could guess that private transactions whose fees are paid by the -same implicit account are from the same user. -This can be mitigated by making a service that act as a proxy by -forwarding the user transactions and paying it fees. The user would -then include in the transaction a shielded output for the service that -covers the fees plus a small bonus to pay the service. -This output can be open by the service before sending the transaction -to check that there is enough money to cover its fees. As for Z-cash, -users interacting with the proxy should use TOR or mitigate network -analysis as they wish. - -Gas, storage and costs -~~~~~~~~~~~~~~~~~~~~~~ - -Gas evaluation is not yet done. - -RPCs -~~~~ - -There are two Sapling RPCs under the prefix `context/sapling`. -`get_size` returns a pair with the size of the set of commitments -and the size of the set of nullifiers. -`get_diff` takes two optional starting offsets `cm_from` and `nf_from` -and returns the sapling state that was added from the offsets to the -current size. In particular it returns three lists, commitments, -ciphertexts from position `cm_from` up to the last one added and -nullifiers, from `nf_from` to the last one added. -Additionally it returns the last computed root of the merkle tree so -that a client updating its tree using the diff can verify the -correctness of the result. - -Client -~~~~~~ - -Wallet -^^^^^^ - -tezos-client supports Sapling keys and can send -shielded transactions to smart contracts. - -The client supports two ways to generate a new Sapling spending key. -It can be generated from a mnemonic using `BIP39 -`_, so -that it can be recovered in case of loss using the mnemonic. -Alternatively it is possible to derive new keys from existing ones -using `ZIP32 -`_, a Sapling -variant of `BIP32 -`_ for -hierarchical deterministic wallets. As usual, in this case it is -important to note the derivation path of the key to be able to recover -it in case of loss. -At the moment there is no hardware wallet support, keys are stored in -`~/.tezos-client/sapling_keys` by default encrypted with a password. -**Users should take care to backup this file.** - -The client can also derive addresses from viewing keys. -By default addresses are generated using an increasing counter called -the address index. Not all indexes corresponds to valid addresses for -each key so it is normal to see an increasing counter that -occasionally skips a few position. - -Because for now the only support for Sapling keys is to interact with -smart contracts, the client binds each newly generated key to a -specific smart contract address. - -Operations -^^^^^^^^^^ - -The client also facilitates the creation of shielded transactions and -their transfer as arguments of smart contracts. -For now there is seamless integration to send transactions to the -reference shielded-tez contract and we are planning to support a -larger class of contracts. - -For the shielded-tez smart contract, the client supports shielding, -unshielding and shielded transactions. -In the case of shielded transactions there are two commands, one to -forge a transaction and save it to file and one to submit it to the -smart contract. -The idea is that a user should not use their own transparent tz{1,2,3} -address to submit a shielded address but rather have a third party -inject it. - -Message argument -^^^^^^^^^^^^^^^^ -Sapling also allows to send an arbitrary encrypted message attached -to an output. -The message size has to be fixed by pool for privacy reasons. -For now it is fixed overall at eight bytes. An incorrect message length -will raise a failure in our client and the protocol will reject the -transaction. Our client adds a default zero's filled message of the -right length. If a message is provided with the --message option, -the client will pad it or truncate it if necessary. A warning message -is printed only if the user's message is truncated. - - -Code base -~~~~~~~~~ - -The current code-base is organized in three main components. -There is a core library called `lib_sapling` which binds `librustzcash`, -adds all the data structures necessary to run the sapling -protocol and includes a simple client and baker. -Under the protocol directory there is a `lib_client_sapling` library -which implements a full client capable of handling Sapling keys and -forging transactions. -Lastly in the protocol there is a efficient implementation of the -Sapling storage, in the spirit of `big_map`s, and the integration of -`SAPLING_VERIFY_UPDATE` in the Michelson interpreter. - -Protocol -^^^^^^^^ - -In order to export the Sapling library to the protocol we first need -to expose it through the environment that sandboxes the protocol. -The changes under `src/lib_protocol_environment` are simple but very -relevant as any change of the environment requires a manual update of the -Tezos node. This changes are part of version V1 of the environment -while protocols 000 to 006 depends on version V0. - -There are two main changes to Tezos' economic protocol, the storage -for Sapling and the addition of `SAPLING_VERIFY_UPDATE` to the Michelson -interpreter. - -Given that the storage of a Sapling contract can be substantially -large, it is important to provide an efficient implementation. -Similarly to what it's done for big_maps, the storage of Sapling can't -be entirely deserialized and modified in memory but only a diff of the -changes is kept by the interpreter and applied at the end of each -smart contract call. - -In the Michelson interpreter two new types are added, `sapling_state` and -`sapling_transaction`, and the instruction `SAPLING_VERIFY_UPDATE`. - -Client -^^^^^^ - -Under `lib_client_sapling` there is the client integration -with the support for Sapling keys and forging of transactions. -The main difference from the existing Tezos client is the need for the -Sapling client to keep an additional state, for each contract. -Because Sapling uses a UTXO model it is necessary for a client to -compute the set of unspent outputs in order to forge new transactions. -Computing this set requires scanning all the state of a contract which -can be expensive. -For this reason the client keeps a local state of the unspent outputs -after the last synchronization and updates it before performing any -Sapling command. -The update is done using the RPCs to recover the new updates since the -last known position. - -The state of all sapling contracts is stored in -`~/.tezos-client/sapling_states`. This file can be regenerated from -the chain in case of loss. However disclosure of this file will reveal -the balance and the unspent outputs of all viewing keys. - -Memo -^^^^^^ - -Sapling offers the possibility to add an arbitrary memo to any -created output. The memo is encrypted and available to anyone -owning the outgoing viewing key or the spending key. -For privacy reasons the size of the memo is fixed per contract -and it is chosen at origination time. -A transaction containing an output with a different memo-size -will be rejected. - -Sandbox tutorial -~~~~~~~~~~~~~~~~ - -As usual it's possible to test the system end-to-end using the -:doc:`../user/sandbox`. -After having set up the sandbox and originated the contract, a good -way to get familiar with the system is to generate keys and then -perform the full cycle of shielding, shielded transfer and -unshielding. - -:: - - # set up the sandbox - ./src/bin_node/tezos-sandboxed-node.sh 1 --connections 0 & - eval `./src/bin_client/tezos-init-sandboxed-client.sh 1` - tezos-activate-alpha - - # originate the contract with its initial empty sapling storage, - # bake a block to include it. - # { } represents an empty Sapling state. - tezos-client originate contract shielded-tez transferring 0 from bootstrap1 \ - running src/proto_011_PtHangz2/lib_protocol/test/integration/michelson/contracts/sapling_contract.tz \ - --init '{ }' --burn-cap 3 & - tezos-client bake for bootstrap1 - - # as usual you can check the tezos-client manual - tezos-client sapling man - - # generate two shielded keys for Alice and Bob and use them for the shielded-tez contract - # the memo size has to be indicated - tezos-client sapling gen key alice - tezos-client sapling use key alice for contract shielded-tez --memo-size 8 - tezos-client sapling gen key bob - tezos-client sapling use key bob for contract shielded-tez --memo-size 8 - - # generate an address for Alice to receive shielded tokens. - tezos-client sapling gen address alice - zet1AliceXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX # Alice's address - - - # shield 10 tez from bootstrap1 to alice - tezos-client sapling shield 10 from bootstrap1 to zet1AliceXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX using shielded-tez --burn-cap 2 & - tezos-client bake for bootstrap1 - tezos-client sapling get balance for alice in contract shielded-tez - - # generate an address for Bob to receive shielded tokens. - tezos-client sapling gen address bob - zet1BobXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX # Bob's address - - # forge a shielded transaction from alice to bob that is saved to a file - tezos-client sapling forge transaction 10 from alice to zet1BobXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX using shielded-tez - - # submit the shielded transaction from any transparent account - tezos-client sapling submit sapling_transaction from bootstrap2 using shielded-tez --burn-cap 1 & - tezos-client bake for bootstrap1 - tezos-client sapling get balance for bob in contract shielded-tez - - # unshield from bob to any transparent account - tezos-client sapling unshield 10 from bob to bootstrap1 using shielded-tez --burn-cap 1 - ctrl+z # to put the process in background - tezos-client bake for bootstrap1 - fg # to put resume the transfer diff --git a/docs/hangzhou/timelock.rst b/docs/hangzhou/timelock.rst deleted file mode 100644 index 7724081f02e21ce580b5ecfc580516ed25d9d3ad..0000000000000000000000000000000000000000 --- a/docs/hangzhou/timelock.rst +++ /dev/null @@ -1,129 +0,0 @@ -Time locked Michelson against Block Producer Extractable Value -============================================================== - - -Block Producer Extractable Value --------------------------------- - -We aim at tackling the issue known through -the unfortunate misnomer of "generalized front running", described -for instance in `here `__. - -Observing a transaction before it is actually included in the chain -can give an advantage to a trader against another one.

In a first period, a contract collects user-submitted and timelock encrypted Michelson values along with some valuable deposit, such as tez. -2.

Consequently the amendment rules themselves are subject to -amendments. - -The rest of this page gives more details about the amendment and voting process. -Other than this page, there is an excellent overview from `Jacob -Arluck on medium `__. - -Periods -------- - -The amendment process consists of five *periods*. Each period lasts for 40960 -blocks (5 cycles) (or approximately two weeks). The periods (listed below) -typically succeed one to another for a total duration of approximately 2 months and -a half, after which the whole amendment process starts again. - -The five periods are as follows: - -- *Proposal period*: During this period, delegates can - - - submit *protocol amendment proposals* (or, simply, *proposals*) using the - ``Proposals`` operation (see below); - - upvote one or several proposals, using the same ``Proposals`` operation. - - Each delegate can submit a maximum of 20 proposals. Duplicates count towards - this total. - - At the end of a **proposal period**, if participation reaches a - :ref:`proposal quorum `, the proposal with most support is - selected and we move to an **exploration period**. Note that support is - measured in the cumulated number of rolls that delegates supporting the - proposal have. E.g., a proposal supported by a single delegate with 100 rolls - has more support than a proposal supported by two delegates with 20 rolls - each. - - If there are no proposals, or a tie between two or more proposals, the process - moves back to a new **proposal period**. - -- *Exploration period*: During this period delegates can cast one - Yay, Nay, or Pass ballot on the selected proposal. They do so using the - ``Ballot`` operation. - - If the voting participation reaches *quorum* and there is a *super-majority* - of Yay, the process moves to the **cooldown period**. (See below for details - on participation, quorum, and super-majority.) - - Otherwise the process moves back to the **proposal period**. - -- *Cooldown period*: On-chain nothing specific happens during this period. - Off-chain the delegates can read the proposal with more scrutiny, the - community can discuss finer points of the proposal, the developers can - perform additional tests, etc. - - At the end of this period, the process moves to the **promotion period**. - -- *Promotion period*: During this period, delegates can cast a Yay, Nay, or Pass - ballots using the ``Ballot`` operation. - - If the voting participation reaches *quorum* and there is a super-majority of - Yay, the process moves to the **adoption period**. - - Otherwise the process moves back to the **proposal period**. - -- *Adoption period*: On-chain nothing specific happens during this period except - on the very last block (see below). - - Off-chain the developers release tools that include support for the - soon-to-be activated protocol, other actors (bakers, indexers, etc.) update - their infrastructure to support the newly released tools, smart-contract - developers start working with soon-to-be-available features, etc. - - At the very end of the period, the proposal is *activated*. This means that - the last block of the period is still interpreted by the current economic - protocol, but the first block after the period is interpreted by the new - economic protocol (the one that was voted in). - - And a new **proposal period** starts. - - -Activation ----------- - -After the activation step, the blocks added to the chain are interpreted in the -newly activated protocol. As a result gas costs may differ, new operations may -be available, contracts using new opcodes may be injected, etc. - -Because the amendment process is also part of the economic protocol, the -amendment process now unfolds according to the rules of the newly activated -protocol. As a result the periods may be lengthened or shortened, a new period -might be introduced, a different selection mechanism may be used, the quorum -requirement might differ, etc. - - -Voting Power ------------- - -When supporting a proposal or casting a Yay, Nay, or Pass ballot, each delegate -has voting power equal to its *stake*. The stake is always measured in -**number of rolls**. - -Note that the stake of each delegate is computed at the beginning of each -period. - - -Super-majority and Quorum -------------------------- - -As mentioned above, during either of the **exploration** or **promotion** periods, -delegates can cast ballots using the ``Ballot`` operation (see below). -In both cases, delegates can cast a single Yay, Nay, or Pass ballot. A ballot -has a weight equal to the delegate's stake as detailed above. - -For either of these two periods, the process continues to the next period if the -*vote participation* reaches *quorum* and there is a *super-majority* of -Yay. - -The *vote participation* is the ratio of all the cumulated stake of cast ballots -(including Pass ballots) to the total stake. - -For the first vote, the *quorum* started at 80% of stake. The quorum is -adjusted after each vote as detailed below. This adjustment is necessary to -ensure that the amendment process can continue even if some delegates stop -participating. After each vote the new quorum is updated based on the old quorum -and the **vote participation** with the following coefficients:: - - new-quorum = 0.8 × old-quorum + 0.2 × participation - -However, in order to avoid establishing quorums close to 100% that would be -very difficult to attain, or, conversely, low quorums close to 0% making -little participation chronicle, the quorums are lower- and upper-bounded by -:ref:`quorum_caps`. - -The *super-majority* is reached if the cumulated stake of Yay ballots is -greater than 8/10 of the cumulated stake of Yay and Nay ballots. - -Note that Pass ballots do not count towards or against the super-majority; -they still counts towards participation and quorum. - -More details can be found in the file -:src:`src/proto_011_PtHangz2/lib_protocol/amendment.ml`. - - -The Hash and the Protocol -------------------------- - -On the one hand, the voting part of the process revolves around the -**hash of a protocol**. Specifically, a delegate submits a hash of a -protocol, and all the delegates cast ballots on the proposed hash. -The *hash of a protocol* is the hash of the files that constitute the source -code of the protocol. - -On the other hand, the **protocol activation** (at the end of the -**adoption period**) revolves around the compiled sources of the protocol. - -Basically, the voting process works on an identifier of the protocol whilst the -activation step works on the protocol itself. Consequently, if a protocol hash -is voted in and the protocol it identifies is invalid, the activation step -fails. - -.. sidebar:: Checking a hash is of a valid protocol - - When a hash is proposed by a delegate, it is usually accompanied by some - blogposts and forum threads on :ref:`community websites `. - These should include directions for testing the proposed protocols.
