LBRYcrd uses a blockchain similar to bitcoin to implement an index and payment system for content on the LBRY network. It is a fork of the bitcoin core. In addition to the libraries used by bitcoin, LBRYcrd also uses icu4c. What if anyone in the world could publish digital content, anyone else in the world could access it (for free or for payment), and that entire system worked without any centralized authority or point of control? LBRY uses a public, proof-of-work blockchain that is very similar to Bitcoin. The blockchain is the foundation of the protocol stack. The most salient feature of the LBRY blockchain is the association of a normalized string of characters (a “name”) with a structured set of metadata. This coupling is called a claim. The LBRY blockchain stores names and metadata in a parallel Merkle tree, separate from the tree used to store transaction data. This allows LBRY URLs to be trustfully resolved even without a full copy of the blockchain.

Grin is an in-progress implementation of the Mimblewimble protocol. Grin is a privacy-preserving digital currency built openly by developers and distributed all over the world. Grin has no amounts and no addresses. Transactions can be trivially aggregated. To hide the origin of a newly created transaction, it gets relayed among a sub-set of peers before it is widely broadcasted. Electronic transactions for all. Without censorship or restrictions. Designed for the decades to come, not just for tomorrow. To be used by anyone, anywhere. Grin is not controlled by any company, foundation, or individual. The coin distribution is designed to be as fair as possible, with emission of 1 GRIN per second. Mimblewimble leverages cryptography to allow past transaction data to be removed with no compromise on security. This avoids Grin collapsing under the weight of data having to be kept on-chain.

Nimiq is a unique open-source payment system. It empowers all humans with decentralized but easy payments. One-click creates a node in your browser. Send and receive directly to the blockchain and be truly independent. A simple, secure and censorship-resistant payment protocol, native to the web. Nimiq is a decentralized, censorship-resistant payment protocol native to the web, with its own diverse ecosystem of apps. The native NIM token is transacted within Nimiq as a store and transfer of value: it acts as digital cash. The cutting-edge, browser-first blockchain approach means that users directly connect to the blockchain with nothing more than a browser. Therefore anyone with an up-to-date browser can join the payment network directly, pay and accept payments without having to install software or rely on unnecessary intermediaries. This gives Nimiq its ‘it just works’ characteristic, which is further strengthened by an ethos of simplicity and ease of use.

Cryptographic currency implementing Ouroboros PoS protocol. The cardano-node is the top level for the node and aggregates the other components from other packages: consensus, ledger and networking, with configuration, CLI, logging and monitoring. The node no longer incorporates wallet or explorer functionality. The wallet backend and explorer backend are separate components that run in separate external processes that communicate with the node via local IPC. The new Cardano implementation consists of more granular components.

Design your new betting currency by choosing a blockchain to run on, a name for your coins and an initial supply. Then create your genesis transaction and import the new coins into your wallet. Next decentralize your currency by installing it on a bunch of different nodes and distributing the coins to any initial investors and stakeholders. PolyCash makes it easy to create a new cryptocurrency for sports betting or betting on any other topic. You can peg your currency to the dollar, the bitcoin or nearly any other source of value.
