关于PoA-Proof-of-Authority-Chains

Proof-of-Authority is a replacement for Proof-of-Work, already working in production of Ethereum, like OpenEthereum, geth.

This article show path of dev, and move to production steps as my github project: WillZhuang/geth-poa-tutorial: Clique Proof-of-Authority Tutorial (github.com). it is working under Geth v1.10.15.

appendix:

1. guide about node append / delete : https://geth.ethereum.org/docs/rpc/ns-clique.

clique.propose(address, auth) / clique.discard(address)

2. Original EIP-225: Clique proof-of-authority consensus protocol (ethereum.org)

3. benchmark: drandreaskrueger/chainhammer: fire many transactions at Ethereum node, then produce diagrams of TPS, blocktime, gasUsed and gasLimit, and blocksize. (github.com)
