    Lightning Network Daemon

    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.

    Eclair

    Eclair

    A scala implementation of the Lightning Network

    Eclair (French for Lightning) is a Scala implementation of the Lightning Network. This software follows the Lightning Network Specifications (BOLTs). Other implementations include c-lightning, lnd, electrum, and rust-lightning. Eclair offers a feature-rich HTTP API that enables application developers to easily integrate. Eclair's JSON API should NOT be accessible from the outside world (similarly to Bitcoin Core API). Eclair requires Bitcoin Core 0.20.1 or 0.21.1. (other versions of Bitcoin Core are not actively tested - use at your own risk). If you are upgrading an existing wallet, you may need to create a new address and send all your funds to that address. Eclair needs a synchronized, segwit-ready, zeromq-enabled, wallet-enabled, non-pruning, tx-indexing Bitcoin Core node. You must configure your Bitcoin node to use bech32 (segwit) addresses.

For more information about setting up Bitcoin Core, please read the full node guide. Download verification is optional but highly recommended. Performing the verification steps here ensures that you have not downloaded an unexpected or tampered version of Bitcoin, which may result in loss of funds. Experienced users who don't mind performing additional steps can take advantage of Bitcoin Core's reproducible builds and the signed checksums generated by contributors who perform those builds.

    Kohaku

    Kohaku

    Privacy-first tooling for the Ethereum ecosystem

    Kohaku is an open-source initiative by the Ethereum Foundation aimed at bringing privacy-by-default tooling into the Ethereum ecosystem. It comprises an SDK of privacy primitives, a reference wallet implementation (browser extension), and a collaboration platform for existing wallet teams to adopt composable privacy building blocks. The project recognizes that privacy leaks in Ethereum go beyond just on-chain visibility — they include RPC endpoints exposing IPs, address reuse across dApps, and metadata captured by analytics or monitoring systems. Kohaku addresses privacy holistically: from local light-client verification (to reduce reliance on centralized RPCs) to per-dApp account isolation (so one user session cannot be correlated across services). It also integrates with existing privacy protocols (e.g., shielded transaction pools) and envisions long-term capabilities like post-quantum signatures, hardware wallet hooks, and minimal-trust data queries (TEE/ORAM or PIR).

    Solana is the fastest blockchain in the world and the fastest-growing ecosystem in crypto, with thousands of projects spanning DeFi, NFTs, Web3 and more. Integrate once and never worry about scaling again. Solana ensures composability between ecosystem projects by maintaining a single global state as the network scales. Never deal with fragmented Layer 2 systems or sharded chains. Solana's scalability ensures transactions remain less than $0.01 for both developers and users. Solana is all about speed, with 400 millisecond block times. And as hardware gets faster, so does the network. Not only is Solana ultra-fast and low cost, but it is also censorship-resistant. This means the network will remain open for applications to run freely and transactions will never be stopped. Help secure the network by running decentralized infrastructure. Learn about operating a validator node. See the get started guide, videos, tutorials, SDKs, reference implementations, and more.

    We are the world’s lightest blockchain, powered by participants. Using zero-knowledge technology, Mina is creating the infrastructure for the secure, democratic future we all deserve. Build on Mina with zkApps, smart contracts powered by zero-knowledge. The SDK, based on Typescript, will be available soon. The Mina blockchain remains ~22kb, enabling users to quickly and directly access the current state from their smartphone and other blockchains. Users today are compelled to hand over their data to centralized entities in order to participate in the modern world. But Mina’s zkApps, smart contracts powered by zero-knowledge, keep users in control of their privacy by validating and sharing proofs of their data, rather than the data itself. Think about getting a loan by simply sharing a proof of your personal ID and credit score, rather than the data itself. No risk of your personal information being hacked or sold. You are the only one owning your data, and it never leaves your device.
