Verifiable Smart Contract Portability [article]

Martin Westerkamp
2019 arXiv   pre-print
To avoid a novel form of lock in effect towards a host blockchain, we introduce a concept for smart contract portability that permits any user to migrate contract logic and state between blockchains in  ...  Hereby, lock in effects originating from isolated data storage and central authorities are mitigated. Yet, smart contracts deployed to a ledger generate dependencies on the underlying blockchain.  ...  A smart contract is deployed and used on blockchain A. It's state is reconstructed to create respective migration code for blockchain B.  ...
