What you need to know about mapping an EOS Public Key to an Ethereum address
WHY MAPPING
These tokens will be worthless ，when ERC20 tokens are FROZEN 24 hours or so after June 1st 2018. It is because of this why mapping an Ethereum address to an EOS public key is so important, you are mapping your EOS ERC20 token balance so that this balance can be included as a snapshot in the genesis block of the EOS blockchain. If the ERC20 Tokens could be transferred on Ethereum after being moved to EOS blockchain, this would cause confusion and dilute valuation, among a bunch of other things.
In regards to locking, I thought you were talking about the locking in regards to locking native EOS tokens. EOS native tokens in the future, will be locked to secure "bandwidth, computation and storage" resources.
