Interconnection of Blockchains Through Secure Multiparty Computation
The interconnected bridges facilitate the seamless transfer of assets between different blockchain chains. Here's an in-depth breakdown:
- 1.Origin Chain Holding: An asset, on its native chain, is directed to a specific address managed through secure multiparty computation (SMC). This address serves as a decentralized escrow, ensuring assets remain intact during the transfer process.
- 2.Token Multiplication on the Destination Chain: Upon reaching the destination chain, a smart contract autonomously replicates the escrowed tokens on a 1:1 ratio and transfers them directly into the user's wallet.
- 3.Reversion Process: Should tokens be sent back to the smart contract, they undergo a "burning" process. Post this, the SMC nodes release the corresponding assets back to the origin chain.
- 1.Asset Transfer and Holding:
- The SMC nodes utilize the designated address of the new bridge for asset transfers.
- This address, governed solely by the SMC nodes, ensures the secure retention of on-chain assets. No external or human-managed addresses have jurisdiction over this address.
- 2.Bridge Creation Between Chains:
- When a new bridge forms between two blockchain chains, SMC nodes synchronize with a novel smart contract on the destination chain, especially for intricate assets.
- This contract, either established as INTDSwap.sol or a customized version of it, is responsible for token burning when assets revert to their original chain.
- 3.Monitoring Centralized Management Account:
- The Centralized Management Account is under the vigilant watch of the multiparty computation nodes.
- Whenever a new asset arrives, the relevant smart contract on the destination chain is triggered.
- 4.Token Burning Protocol:
- In the event of asset burning, the Wrapped Asset smart contract is instigated by the SMC nodes to execute the process.
- Post this, assets held in the management account are released and transmitted to the user.
The INTDSwap complex asset token contract, present on the destination chain, is an enhanced version of the standard XRC20 contract. It exclusively permits a network of multiparty computation nodes to mint assets. To ensure there's no mismatch between the assets at the SMC address and the created complex assets, no external addresses are authorized to conduct multiplication.
In conclusion, assets, whether innate or developed via the INTD Bridge, can be effortlessly transferred across multiple chains, ensuring a seamless and secure blockchain experience.
