Blockchain bridges: Doge-Ethereum and BTC Relay

The history of the Doge-Ethereum bridge is intertwined with that of Truebit. It played a part in original discussions of the protocol, generated a bounty which is now funding a massive open-source art-project, and led to the first full implementation of Truebit.
Sina Habibian will present two components of the bridge:

1. an implementation of Truebit for verification of Doge’s proof-of-work (live on the Rinkeby testnet).
2. the collateralized peg, a novel cryptoeconomic scheme, to connect Doge to Ethereum without a hard/soft fork. A similar construction can be used to connect other UTXO chains (e.g. Bitcoin) to Ethereum.

For the first 30 mins, Joseph Chow will recap the first bridge on Ethereum, BTC Relay and will go through some of its code to demystify what it means for a smart contract to be able to verify transactions from another blockchain. Prior familiarity with BTC Relay (btcrelay.org) and Merkle trees is expected.

Thank you to the Stanford Bitcoin Club (blockchain.stanford.edu) for co-hosting us!
