Datahaven is a decentralized storage network and smart contract platform designed for storing verifiable data with cryptographic integrity checks. It functions as a peer-to-peer system that ensures data availability and prevents loss through redundancy and tamper-evident content addressing. The project incorporates a restaking security layer that protects the network from malicious actors by leveraging economic stakes and automated slashing mechanisms. It also features a cross-chain asset bridge that transfers tokens and messages between different blockchain networks using finality proofs. T

Diem is a distributed ledger technology platform designed for the development of decentralized applications and the execution of programmable financial transactions. It provides a comprehensive framework for operating validator nodes that maintain ledger integrity through a Byzantine fault-tolerant consensus protocol, ensuring consistent state updates across a distributed network of participants. The platform distinguishes itself through a modular node architecture that decouples consensus, execution, and storage to facilitate scalability and maintenance. It utilizes a resource-oriented virtu

Foundry is an Ethereum smart contract development toolkit and blockchain simulator designed for compiling, testing, and deploying contracts for the Ethereum Virtual Machine. It provides a local environment for simulating blockchain state and forking live networks to execute code without modifying the actual chain. The project features a property-based fuzzing engine to identify edge-case failures in contract logic and a transaction debugger for analyzing detailed execution traces and gas consumption. It enables developers to mirror the state of a remote chain locally to test against real-worl

A highly modular Bitcoin Lightning library written in Rust. It's rust-lightning, not Rusty's Lightning!

Linera is a multi-chain smart contract platform designed for horizontal scalability through a microchain-based distributed ledger. By partitioning state into independent, parallel chains that share a common validator set, the protocol enables high-performance execution of modular applications. The system utilizes a WebAssembly-based runtime to ensure secure, platform-independent execution of contract logic across the network. The platform distinguishes itself through an asynchronous messaging framework that coordinates state changes between chains by queuing messages for execution in subseque

Grin is a protocol implementation and blockchain node that provides a confidential transaction system. It uses Pedersen Commitments and homomorphic encryption to verify value integrity and ensure a consistent money supply without revealing specific transaction amounts or participant identities. The project distinguishes itself through an interactive transaction exchange model, where wallets coordinate multi-round data exchanges to build signed transactions. To maintain anonymity, the system supports onion-routed transaction delivery and masks originating IP addresses through specialized relay

Sui is a blockchain platform featuring an object-centric state model and resource-oriented smart contracts. It utilizes parallel transaction execution to increase network throughput and supports programmable transaction blocks that bundle multiple operations into single atomic units. The platform distinguishes itself with a capability-based access control system and zero-knowledge login mechanisms, enabling users to authenticate via identity providers without seed phrases. It also implements deterministic object addressing to allow predictable state lookups and supports the creation of soulbo
