\section{Interoperability}
|
|
|
|
|
|
Lux bridges to existing blockchains through the \textbf{Lux Bridge},
|
|
a non-custodial cross-chain protocol based on multi-party threshold
|
|
signing. A group of MPC signers, themselves drawn from the Lux
|
|
validator set, collectively control a multisig on each destination
|
|
chain. The MPC protocol (CGGMP21 for ECDSA secp256k1, FROST for
|
|
Ed25519) ensures that no single signer ever holds the full
|
|
private key, and the threshold $t$ of $n$ is set high enough that
|
|
no small coalition can seize bridge funds.
|
|
|
|
Cross-chain transfers are settled via atomic swap: the user locks
|
|
assets on the source chain, an MPC-signed proof is posted to the
|
|
destination chain, and the user receives the equivalent wrapped
|
|
asset. Reverse transfers burn the wrapped asset and unlock the
|
|
original.
