Lightning Bitcoin is a fork of the Bitcoin blockchain. By adopting DPoS consensus mechanism with 2M blocksize, Lightning Bitcoin improves transaction speed, promotes decentralization and also supports smart contracts. Lightning Bitcoin combines the advantages of Bitcoin and Ethereum and creates a more valuable and functional blockchain system.
Shardus is building distributed ledger software to remedy the problems of traditional blockchains -- scalability, decentralization and efficiency. The technology being developed will use compute and state sharding to accommodate billions of daily active users, allowing for global-scale decentralized networks.
