To reduce the pressure on the mainchain and provide a better experience for decentralized applications (dApps), Elastos adopts a mainchain and sidechain hierarchical structure. The mainchain is exclusively accountable for security, governance and the circulation of ELA, while dApps operate on sidechains. The Elastos mainchain-sidechain arbitration mechanism ensures secure transfer of value through a bidrectional anchoring mechanism.
The currently registered sidechains are listed in the table below.
|Elastos Smart Contract Chain (ESC)||Specialized EVM-based sidechain for more advanced applications|
|Elastos Identity Chain (EID)||EVM-based sidechain custom built for issuing and managing digital identities|
Elastos' architecture is not limited to only the sidechains that exist today. New ones can be added and operated independently using their own governance rules, including both Private and Public chains.
