Blockchain Interoperability

Definitions

• Interoperability: The ability of systems to work together.
• Blockchain: A distributed ledger technology that allows secure, transparent transactions.
• Cross-chain Communication: The process of transferring data and value between different blockchain networks.

Categories

1. Technical Interoperability: Involves protocols and standards that allow different systems to communicate.
2. Semantic Interoperability: Ensures that the meaning of the exchanged data is understood by all parties.
3. Process Interoperability: Involves the integration of business processes across different organizations.

Popular Protocols

• Polkadot: A multi-chain framework that enables various blockchains to interoperate.
• Cosmos: A network of independent blockchains that can communicate with each other.
• Wanchain: Focuses on cross-chain transactions and asset transfers.

Example Code Snippet

const { ApiPromise, WsProvider } = require('@polkadot/api');
                    
                    const main = async () => {
                        const provider = new WsProvider('wss://rpc.polkadot.io');
                        const api = await ApiPromise.create({ provider });
                        const result = await api.query.system.chain();
                        console.log(`You are connected to chain: ${result}`);
                    };
                    
                    main();
