Lustration Proposal: Verifying Beam's Supply Integrity
Following the emergency hard fork 6 and the correction of the vulnerability in the Bulletproofs implementation, this post details a 'lustration' process which is proposed as a one-time mechanism to verify Beam's circulating supply. The post is intentionally thorough, because the proposal involves a trade-off between privacy and supply certainty that every member of the community should understand when forming an opinion about it. This post aims at serving as a reference document for the upcoming BeamX DAO vote on whether to implement the lustration.
Hard Fork Six
Beam has completed a necessary security hard fork to address a subtle Bulletproofs rangeproof vulnerability discovered in the Beam core code. The issue was responsibly disclosed, reviewed by the developers, patched in a non-public branch, and resolved through a coordinated network upgrade. This post explains the technical background, our current risk assessment, and a proposed lustration process that would allow the community to verify supply integrity with a one-time, limited disclosure of legacy outputs.
