Would be cool if https://renproject.io/ technology will be used as a trustless bridge to transfer MAID from Bitcoin blockchain to an Ethereum ERC20 MAID. In app idea 12 they talk about integrating USDT OMNI tokens: https://medium.com/renproject/12-app-ideas-using-renvm-eb08fb095499
RenVM is a Smartcontract with Zero Knowledge technology running on the Ethereum Blockchain. It generates a BTC (or BCH/ZEC) privatekey, create a public address to deposit BTC, create a trustless bridge to Ethereum and mint renBTC ERC20 tokens. In this PoC you can exchange BTC for ERC20 SAI: https://chaosdex.renproject.io/
Next to the advantage to have a MAID ERC20 token on the Ethereum blockchain, this technology can be used to create a trustless bridge between MAID and Safecoin when Safenetwork goes life. This also solves the liquidity (and centralized exchange) problem with Safecoin in the future, like we now have with MAID.
