This interoperability is crucial for realizing the full potential of blockchain technology, fostering a more integrated and efficient digital economy.
Core Concepts
1. Oracles
Oracles are the linchpins of cross-chain communication. They act as intermediaries that fetch and verify data from external blockchains and relay it to the intended blockchain. Think of oracles as the messengers that carry the critical data and information between different blockchain worlds. Examples of oracles include Chainlink, Band Protocol, and OraclesLab.
2. Smart Contracts
Smart contracts play an essential role in cross-chain messaging. These self-executing contracts with the terms of the agreement directly written into code facilitate automated transactions and data exchanges. By leveraging smart contracts, cross-chain systems can ensure that the data transferred is accurate and that the transactions are executed without human intervention.
3. Bridges
Bridges are protocols or infrastructures that enable the transfer of assets from one blockchain to another. They work by locking assets on one blockchain and minting equivalent assets on another. This process ensures that the value and integrity of the assets are maintained across chains. Popular bridge technologies include Polkadot’s parachains and Cosmos’s IBC (Inter-Blockchain Communication).
Key Protocols
