Why does rotating a compromised wallet erase my entire on-chain history?

Oportunidade

When a private key is leaked or lost, the only safe move is to abandon the address, but every piece of on-chain reputation, governance votes, lending history, and attestations stays with the old key. Moving those records to a new address requires publishing the link publicly, which permanently deanonymizes both addresses. Existing ZK identity schemes handle fresh anonymity sets but not migration of accumulated history between pseudonyms. A 2025 arXiv survey of decentralized identity systems identified key recoverability as one of the two dominant unsolved properties across all major DID methods. No production primitive exists that lets a user prove continuity to a new address under zero-knowledge while keeping the link between old and new private.

Por que importa

Without a safe migration primitive, key rotation is practically impossible for anyone with meaningful on-chain history, which means compromised keys stay active far longer than they should.

Como avalio a oportunidade

A Pontuação de Oportunidade é minha própria leitura, não uma medição: o quanto dói, com que frequência aparece e o quanto pouco existe para resolvê-lo hoje. Quanto maior, mais vale a pena construir, na minha opinião.
