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!

About the Speakers

Sina Habibian works on the design and development of cryptoeconomic protocols at Truebit. He previously built the data platform at Omada Health, did computational physics at the Max Planck Institute, and ran a software engineering consultancy.

Joseph Chow works at ConsenSys helping it and the Ethereum ecosystem grow locally (Silicon Valley and Stanford) and globally with efforts on smart contract security and education. He built BTC Relay, the Ethereum bridge with Bitcoin, has written several articles on Ethereum, and is one of the authors of https://github.com/ConsenSys/smart-contract-best-practices
