Show HN: Burn ETH, mint BURNTH, a contract-less privacy solution on Ethereum (github.com)

While researching on privacy solutions and applications of ZKP, we discovered a technique, by which people can burn their digital asset (E.g ETH) by sending it to an unspendable address, and later build a ZK proof showing that some amount of tokens reside in an account that are unspendable, without revealing the account.

Burnth is a practical implementation of such a protocol.
