Polkadot won. Eventually it will just encapsulate everything. L1s, L2s, rollups - you name it. Position yourself accordingly, it's just a matter of time.

>Today we're excited to introduce Hyperbridge - an interoperability coprocessor capable of scaling cryptographically secure, consensus & state-proof based interoperability to all blockchains.

>Secure cross-chain communication requires the verification of consensus, consensus faults, state proofs, and state transitions.

>However, these verification processes are typically too expensive to be performed on-chain.

>This limitation leads to using trusted intermediaries.

>Secure Interoperability necessitates the coprocessor model. Where the computation is performed off-chain and the results are presented on-chain with cryptographic proofs of its correct execution.

>A popular example of a coprocessor is a SNARK, but SNARKs alone are too expensive.

>With this in mind, we take the hybrid approach. Combining both SNARKs and a blockchain to form an Interoperability coprocessor. However, the blockchain must possess:

>- High cryptoeconomic security.
>- Highly scalable blockchain architecture.
>- Cheap consensus & state proofs.

>Hyperbridge (short for hyper-scalable bridge) is an interoperability coprocessor that has been designed with all of the considerations given above.

>By leveraging Polkadot as a consensus layer, we obtain high crypto-economic security, equivalent to about $2.75 billion at the time of writing.

>This results in a bridge with the highest crypto-economic security today.

>Hyperbridge also leverages Polkadot as a verifiable computation layer, using multiple parachain cores to perform all the necessary computation for secure cross-chain interoperability achieving the elusive full node level security in cross chain bridges.
