Deep Dive into the Technical Mechanisms
Lightning Network Mechanics
The Lightning Network functions through the creation of payment channels between two parties. When a channel is opened, both parties lock a certain amount of Bitcoin in a multi-signature wallet. This allows them to transact off-chain, with the final balance being settled on the Bitcoin blockchain when the channel is closed.
Channel Funding: Parties fund the channel with Bitcoin, which is locked in a multi-signature wallet. This wallet can only be accessed by both parties’ private keys.
Off-Chain Transactions: Transactions occur instantly and without fees, as long as the channel remains open. Each transaction updates the balance in the multi-signature wallet.
Closing the Channel: When a channel is closed, the final balance is recorded on the Bitcoin blockchain. If one party tries to close the channel with an incorrect balance, the network can detect this and penalize the party.
Relayer Networks: To further enhance usability, relayer networks exist, where relayers charge a small fee to forward transactions between channels, providing liquidity and helping to connect disparate channels.
ZK-Rollups Mechanics
ZK-Rollups bundle many transactions into a single batch and use zero-knowledge proofs to verify the correctness of this batch. This proof is then submitted to the Bitcoin blockchain.
Transaction Bundling: Multiple transactions are grouped into a single batch. This batch is then verified using a zero-knowledge proof.
Zero-Knowledge Proofs: These proofs ensure that the batch of transactions is valid without revealing the details of the individual transactions. This maintains privacy while ensuring the integrity of the batch.
On-Chain Rollup: The ZK-rollup contract on the Bitcoin blockchain holds the state of the rollup, and the single proof is submitted periodically to update the state.
Efficiency: By significantly reducing the number of transactions recorded on the Bitcoin blockchain, ZK-Rollups enhance network efficiency and lower transaction costs.
