Ethereum Data Channel
WebRTC-based communication layer for wallet-authenticated off-chain coordination between Ethereum dApp participants.
Ethereum Data Channel was a research prototype for a simple but important idea: decentralized applications often need a peer-to-peer communication layer, and not every state update should become an on-chain transaction.
The project used WebRTC RTCDataChannel connections plus a signaling layer to let participants exchange state updates directly. In the thesis-era implementation, that channel was tied to wallet-oriented flows such as MetaMask-based signing and structured messages, so it could support blockchain applications rather than just generic chat-style messaging.
Its clearest role was as the communication layer for the Pig state channel game, where two players needed to exchange signed updates off-chain before settlement or dispute resolution. In practice it was an enabling transport layer for state-channel coordination.
The architecture question it addresses is still open: if the blockchain is the settlement layer, what is the right off-chain channel for the live interaction? This project was my answer at the time.
