Release Notes for Klaytn v1.2.0
Highlight - The first official release of Service Chain
We are pleased to announce that this version officially supports Service Chain. Service Chain is Klaytn’s layer-2 solution designed to achieve horizontal scalability. Service chains run independently from the Klaytn main chain and can have own governance. To learn more about the Service Chain, please visit https://docs.klaytn.foundation/klaytn/scaling-solutions.
New Features
Service Chain features
Data anchoring: Service chain data can be anchored to a parent chain via ChainDataAnchoring transaction.
Cross-chain value transfer: KLAY and KCT can be transferred between a service chain and a parent chain.
High Availability: Multiple bridge nodes can be set up in an H/A configuration to reduce downtime due to accidental hardware/software failure.
New APIs for Service Chain
klay_getDecodedAnchoringTransactionByHash
subbridge_getParentOperatorBalance
subbridge_getChildOperatorBalance
subbridge_getAnchoringTxHashByBlockNumber
subbridge_getValueTransferOperatorThreshold
subbridge_setValueTransferOperatorThreshold
subbridge_registerOperator
subbridge_getRegisteredOperators
Fixes
Fixed a race condition in txpool.
Improvements
Only unlocked tokens can be moved across chains.
