Panautomata

This is a research project to make it easy for developers to write smart contracts which run across multiple block-chains without the complex underlying logic that makes it possible.

Think of this as being a cross-chain oracle for events and transactions, or it could potentially extended to be used as a way of integrating legacy systems with the Ethereum compatible block-chains.

Examples

• Ping Pong - A session between smart contracts on different chains which send 'Ping' and 'Pong' events to each other in sequence.
• Cross Token - Tokenized remote Ether, redeemable with proof of burn
• Atomic Swap - Cross-chain atomic token swap

If you have interesting use cases, or would like to see integration and interoperability with interesting things, please add a ticket
