Secure Interoperability
Secure interoperability between networks can only be facilitated by the exchange of interoperability proofs which confirm the finality of cross chain messages.
Interoperability Proofs
Interoperability proofs are a combination of Consensus proofs, State proofs and Fraud proofs needed to facilitate secure data exchange between networks.
Consensus Proofs
Consensus proofs are cryptographic proofs that confirm the finality of cross-chain transactions. These proofs are required to authenticate the irreversible state of a blockchain.
State Proofs
State proofs are unforgeable merkle proofs of the information stored on the blockchain, whether that's account balances or arbitrary items in contract storage.
Fraud Proofs
Fraud proofs are proofs of 51% attacks or other kinds of malicious behaviour. These proofs allow Hyperbridge to be fully Byzantine-fault tolerant, the first of its kind in bridges today.
Hyperbridge vs "The Competition"
| # | Bridge | Security Assumption | Economic Security | Storage Queries | Permissionless Relayers |
|---|---|---|---|---|---|
| 1 | Hyperbridge | Consensus, State & Fraud proofs | $4Bn | Yes | Yes |
| 2 | Axelar | Oracle-based, validators attest to cross-chain state | <$1Bn | No | No |
| 3 | Wormhole | Oracle-based, 13/19 "Guardians" attest to cross-chain state | <$1Bn | No | No |
| 4 | Layerzero | Oracle-based, 2/2 Multisig between a relayer & oracle | N/A | No | No |
| 5 | Hyperlane | Oracle-based, Multisig ISM | N/A | No | No |
