Sidechains: Decoupled Consensus Between Chains
This addresses the need for efficient cross-chain interoperability in blockchain systems, though it appears incremental as it builds on existing sidechain concepts.
The authors tackled the problem of secure and decentralized cross-chain transfers by proposing a novel sidechain construction compatible with the Horizen blockchain, showing that their mechanism is secure under plausible assumptions.
We propose a novel sidechain construction tailored to be compatible with the Horizen blockchain and designed for conducting secure and decentralized cross-chain transfers without requiring the mainchain nodes to track sidechains to verify them. The proposed scheme can also be adopted for other similar blockchain systems. We show that our cross-ledger transfer mechanism is secure under certain plausible assumptions.
