Transfer tokens between Algorand and Ethereum using the additional security of State Proofs and Hardware Enclaves.
Uses Intel SGX hardware secure enclave technology to verify each blockchain, send transactions and manage keys, all using predefined and attested code tied to the bridge contracts.
Uses Algorand State Proofs to verify and confirm the correct state of the Algorand blockchain. State Proofs are a unique technology developed by Algorand to enable the most secure and compact verification.
Multiple instances of bridge relayers deployed across a number of unrelated entities with decentralised governance.
The London Bridge operators have no access to private keys, nor can they influence the code used to communicate, verify or send transactions to the blockchains without first upgrading the smart contracts (thereby providing full transparency).
Enclave hardware manufacturer attestation, linked to the bridge smart contracts, is used to ensure that only expected and confirmed pre-programmed operations can be executed by the bridge.
London Bridge is designed to make a complex process feel simple and intuitive.
Transferring valuable tokens across a bridge can be a daunting experience, especially when the user is kept in the dark waiting for confirmations. London Bridge is designed to keep the user informated every step of the way.
Developed by Applied Blockchain, an experienced Algorand partner. London Bridge is supported by an Algorand Foundation SupaGrant.
