This release enables the Bokbunja hardfork in fixed block #44671396 on the METADIUM TESTNET. The expected date for this transition is 2023-09-26 03:00:00 +UTC.

Gmet m0.10.0.testnet is a scheduled feature release containing several significant improvements and new features to METADIUM TESTNET:

Bokbunja hardfork

  • Introduction of a fee delegation function and related RPC API, allowing users to delegate transaction fees to another account.
  • To verify the block miner's signature, the verification nodes use the miner's public key registered in the governance contract.
  • To decentralize mining, the miner selection strategy has been changed to use etcd lockable tokens.

New features

  • Implementation of Verifiable Random Function (VRF) verification functionalities through pre-compiled contracts, offering a more secure and transparent method of generating random numbers on the blockchain.
  • Added eth_getReceiptsByHash JSON-RPC API. Returns all the transaction receipts for the given block hash.
  • Added to Gmet CLI flags to allow changing value of triesInMemory
  • Changed to create blocks by sorting transactions in descending order of gas price
  • Increased the default value of 'TxLookupLimit' flag from 2350000 to 31536000
  • Ethereum Ploitari release(v1.10.17) was applied
  • Ethereum Sharblu release(v1.10.18) was applied
  • Block interval is fixed to 2 seconds.
  • Network members can make more types of decisions through improved governance contracts.
