Over the weekend, a few of us from Base64 threw together a proof-of-concept, totally experimental project. Ethereum NFTs on Bitcoin.

ERC-721 NES, or Non Escrow Staking, is a novel implementation of a staking model that does not require the owner of a token to lock it into an escrow contract. What that means is the token never moves during the staking process, unlike traditional protocols where you receive a coupon to then redeem later for your staked tokens. Instead, the token is flagged as non transferrable for the entire staking duration. In this way, the owner of a token has zero exposure to the risk of a staking protocol being compromised and their tokens stolen.
