What are Sidechains?
Sidechains are separate blockchain networks that run in parallel to a main blockchain, enabling assets and data to move between the two while operating independently. Tools in this category include sidechain protocols, bridges, validators, and infrastructure services that facilitate secure communication and transaction processing between the main chain and sidechains. These tools primarily serve developers and product teams looking to scale applications, reduce transaction costs, or add custom features without congesting the main blockchain. Key characteristics of sidechain tools include interoperability with the main chain, independent consensus mechanisms, and support for asset transfers. Related categories include interoperability solutions and layer 2 scaling tools. Developers should consider sidechain tools when they need to offload transactions from a congested mainnet or require a customizable environment that maintains a connection to a primary blockchain.
