Reputation‐based consensus algorithms are one of the most promising, but least investigated types of consensus algorithms. Its limitation to persmissioned node identity management shades its potential and causes many applications to find blockchain unsuitable. In this paper, we upgrade PoRX, an existing consensus algorithm, into becoming the first permissionless pure reputation‐based consensus algorithm. This upgrade is highly potential since it only affects the admission process and does not intervene with the consensus process, thus can be extended into other types of consensus algorithms.
