After many months of development and testing on the testnet, the AERGO 1.0.0 core technology has now been released. We are finally ready to release the first stable version of AERGO, a major milestone in our development progress.

We have already conducted a few rehearsals using the AERGO 1.0.0 software, and have just upgraded the testnet to this version.

This release includes numerous bug fixes, performance improvements, and new features from our last release. The following is a list of the most important changes. Please refer to the documentation (to be published shortly on for details on specific features.

New features in this release

  • Fee system

On public networks, transactions require a fee that follows a gas system. The minimum fee is 0.002 AERGO. An additional fee is required for TX payload and state DB storage.

  • Transaction

Require hash of chain ID in tx body to prevent replay attack.


consensus info: blockchain call now returns consensus info field. This contains a current list of BPs. On dpos chains, this includes information about the last irreversible block (LIB).

chain id hash: blockchain call now returns the chain id hash for easy use in signing transactions

server info: new API method to retrieve server configuration

  • Smart contract, additional functions

system.isContract(addr), contract.stake(amount), contract.unstake(amount),,…. or {candidates})

abi.register_view(func). register a function that disallows modification of state

Add payable and view flags to ABI

If you used the RPC API directly, refer to the aergo-protobuf changelog for a list of breaking changes.

Stability improvements

  • Transaction receipt

On contract call error, tx receipt status is now ‘ERROR’ with the error message in the result field.

  • aergo.system

The minimum amount of staking is based on the stored amount, not the amount requested. The staked amount is added to the balance of aergo.system for consistency.
