Bitcoin Next Generation (Bitcoin-NG)
Web3 / blockchain technology
Bitcoin-NG is a blockchain protocol design that addresses Bitcoin's scalability limitations by separating block production into two distinct phases: leadership election and microblock creation. In this model, a leader is elected through a process similar to Bitcoin's proof-of-work, then generates microblocks rapidly without waiting for consensus confirmation, reducing latency and increasing transaction throughput. Once a new leader is elected, previous microblocks are finalized and committed to the blockchain. Bitcoin-NG maintains Bitcoin's security model and decentralization properties while achieving significantly higher transaction throughput than the original protocol, making it a theoretical improvement addressing Bitcoin's throughput constraints.
Example
Bitcoin-NG was proposed in academic research as a conceptual improvement, demonstrating how leader-based microblocking could increase Bitcoin-like networks from roughly 7 to over 3,600 transactions per second.
Why It Matters
Bitcoin-NG illustrates how separating leader election from transaction finalization can dramatically improve blockchain scalability while preserving decentralization, influencing designs of subsequent blockchain protocols.
