Hi guys,
I've launched Lost Ethereum, a new proof-of-mistake ERC20 token that lets people redeem address spelling mistakes as LOST tokens.
You can check out the Dapp, a web3 enabled site at
http://www.lostethereum.com/It requires either MetaMask installed in chrome, Mist, or a properly configured local Parity or Geth instance that accepts loopback RPC.
The lost token is like a proof-of-burn receipt. A quick example, let's say I was trying to transact with an exchange or sending ether to myself but instead of 0x8bf2372d9d51c5874637D6fdA665452d52CaA37e I sent the ether to 0x8bf2372d9d51c5874637D6fdA665452d52CaA37f
I wouldn't be able to spend the second address, and neither would the exchange. In fact there is basically no chance that I control both of those keys, so the LOST contract will generate tokens equivalent to the number in the second address if I can prove ownership of a nearby address. It should act as a proof of burn for that ether, as well as a contract that can be queried to establish proof-of-burn, or possible redemption of Ether itself at some point in the future.
In any event, it's designed to help people who have inadvertently lost Ether through a mistake of their own, or a malfunctioning wallet that didn't properly implement a CRC.
