Bridging interoperability gaps between blockchains
So far, you have learned about quite a few L1 blockchains, including Bitcoin, Ethereum, BSC, and Avalanche. Most L2 rollups and sidechains are considered separate blockchains, according to modular blockchain architecture since they mainly offload transaction executions from the L1 chain and rely on the main chain for security.
Limitations in mainstream blockchains such as Ethereum and Bitcoin, as well as mass adoption of DeFi and other Dapps, have propelled the growth of other blockchains, such as BNB smart chains, Avalanche, and Solana, and the transition to L2 rollups. Blockchains are like individual countries. Each has its own protocol rules, ecosystems, and cryptocurrency, which creates an interoperability gap between different blockchains. Without proper channels, you can’t take your asset or your data from one chain to another chain, or back and forth. Cross-chain interoperability refers to the means to communicate...
