Lightning Network Daemon
A complete implementation of a Lightning Network node
The Lightning Network Daemon (lnd), is a complete implementation of a Lightning Network node. lnd has several pluggable back-end chain services including btcd (a full-node), bitcoind, and neutrino (a new experimental light client). The project's codebase uses the btcsuite set of Bitcoin libraries and also exports a large set of isolated re-usable Lightning Network-related libraries within it, and fully conforms to the Lightning Network specification (BOLTs). BOLT stands for Basis of Lightning Technology. The specifications are currently being drafted by several groups of implementers based around the world including the developers of lnd. The set of specification documents as well as our implementation of the specification is still a work in progress. The daemon has been designed to be as developer-friendly as possible in order to facilitate application development on top of lnd. Two primary RPC interfaces are exported, an HTTP REST API, and a gRPC service. -

Swarm Bee
Bee is a Swarm client implemented in Go
Bee is a Swarm client implemented in Go. It’s the basic building block for the Swarm network: a private; decentralized; and self-sustaining network for permissionless publishing and access to your (application) data.There are two versioning schemes used in Bee that you should be aware of. The main Bee version does NOT follow strict Semantic Versioning. Bee hosts different peer-to-peer wire protocol implementations and individual protocol breaking changes would necessitate a bump in the major part of the version. Breaking changes are expected with bumps of the minor version component. New (backward-compatible) features and bug fixes are expected with a bump of the patch component. Major version bumps are reserved for significant changes in Swarm's incentive structure. The second set of versions that are important are the Bee's API versions (denoted in our Bee and Bee Debug OpenAPI specifications). -

BNB Chain
A Binance Smart Chain client based on the go-ethereum fork
The goal of Binance Smart Chain is to bring programmability and interoperability to Binance Chain. In order to embrace the existing popular community and advanced technology, it will bring huge benefits by staying compatible with all the existing smart contracts on Ethereum and Ethereum tooling. And to achieve that, the easiest solution is to develop based on the go-Ethereum fork, as we respect the great work of Ethereum very much. Binance Smart Chain starts its development based on go-ethereum fork. So you may see many toolings, binaries and also docs are based on Ethereum ones, such as the name “geth”. But from that baseline of EVM compatible, Binance Smart Chain introduces a system of 21 validators with Proof of Staked Authority (PoSA) consensus that can support short block time and lower fees. The most bonded validator candidates of staking will become validators and produce blocks. -

Vega Wallet
A command line wallet service for Vega for trading derivatives
Vega has a self-hosted, local wallet. To use it follow the instructions on the Create a Vega Wallet page. Using this wallet, your keys will be completely disassociated from your personal identity, and we will have no way to connect them, unless you share your public key for any reason. For Fairground, Vega has also hosted a version of the wallet server, to make it easier to quickly start trading. A hosted wallet service is a website that manages wallet access for multiple users. Each user only has access to their own wallets. Wallet files are stored remotely, not on your computer, and access is only possible via the website. Even though this is a testnet, you should never share your private keys, or your wallet passphrase. Whether you use the Vega-hosted wallet server, or the self-hosted wallet, the Vega network doesn’t know about the Vega wallet server, or anything about your login information locally, or your personal information. -

Blockchain Guide
Introduce blockchain related technologies, from theory to practice
Blockchain is a fundamental innovation in the field of financial technology (Fintech). As the core technology of a new generation of distributed ledger technology (DLT) system, blockchain is considered to have broad application prospects in many fields such as finance, Internet of Things, commercial trade, credit reporting, and asset management. At present, blockchain technology is still in a stage of rapid development, involving distributed systems, cryptography, game theory, network protocols, and many other disciplines, which bring challenges to both learning and practice. This book hopes to objectively explore the ins and outs of the blockchain concept, analyze key technologies and principles, and use the world's largest open-source distributed ledger project, Hyperledger, as an example to explain specific applications. In the process of developing the Hyperledger project and designing solutions for enterprises, the author has accumulated some practical experience. -

Erigon
Ethereum implementation on the efficiency frontier
Erigon is an implementation of Ethereum (execution client), on the efficiency frontier, written in Go. For an Archive node of Ethereum Mainnet we recommend >=3TB storage space: 1.8TB state (as of March 2022), 200GB temp files (can symlink or mount folder <datadir>/etl-tmp to another disk). Ethereum Mainnet Full node ( see --prune* flags): 400Gb. Erigon by default is "all in one binary" solution, but it's possible start TxPool as separated processes. Same true about: JSON RPC layer (RPCDaemon), p2p layer (Sentry), history download layer (Downloader), consensus. Don't start services as separated processes unless you have clear reason for it: resource limiting, scale, replace by your own implementation, security. How to start Erigon's services as separated processes, see in docker-compose.yml. -

LBRY Chainquery
Chainquery parses and syncs the LBRY blockchain data
Chainquery consists of 4 main parts. The API Server, the Daemon, the Job Scheduler, and the upgrade manager. 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? While the blockchain is the innovation that makes LBRY possible, the Data Network is the layer that actually makes the blockchain useful. The job scheduler schedules different types of jobs to update the Chainquery database example. These jobs synchronize different areas of the data either to make queries faster or ascertain information that is not directly part of the raw blockchain. The example provided is leveraged to handle the status of a claim which is actually stored in the ClaimTrie of LBRYcrd. So it runs periodically to make sure Chainquery has the most up-to-date status of claims in the trie. -
