@ -332,7 +332,7 @@ protocol-related settings described in the table below.
| --- | --- | --- | --- | --- |
| CommitteeHistory | map[uint32]uint32 | none | Number of committee members after the given height, for example `{0: 1, 20: 4}` sets up a chain with one committee member since the genesis and then changes the setting to 4 committee members at the height of 20. `StandbyCommittee` committee setting must have the number of keys equal or exceeding the highest value in this option. Blocks numbers where the change happens must be divisible by the old and by the new values simultaneously. If not set, committee size is derived from the `StandbyCommittee` setting and never changes. |
| Genesis | [Genesis](#Genesis-Configuration) | none | The set of genesis block settings including NeoGo-specific protocol extensions that should be enabled at the genesis block or during native contracts initialisation. |
| Hardforks | `map[string]uint32` | [] | The set of incompatible changes that affect node behaviour starting from the specified height. The default value is an empty set which should be interpreted as "each known hard-fork is applied from the zero blockchain height". The list of valid hard-fork names:<br>• `Aspidochelone` represents hard-fork introduced in [#2469](https://github.com/nspcc-dev/neo-go/pull/2469) (ported from the [reference](https://github.com/neo-project/neo/pull/2712)). It adjusts the prices of `System.Contract.CreateStandardAccount` and `System.Contract.CreateMultisigAccount` interops so that the resulting prices are in accordance with `sha256` method of native `CryptoLib` contract. It also includes [#2519](https://github.com/nspcc-dev/neo-go/pull/2519) (ported from the [reference](https://github.com/neo-project/neo/pull/2749)) that adjusts the price of `System.Runtime.GetRandom` interop and fixes its vulnerability. A special NeoGo-specific change is included as well for ContractManagement's update/deploy call flags behaviour to be compatible with pre-0.99.0 behaviour that was changed because of the [3.2.0 protocol change](https://github.com/neo-project/neo/pull/2653).<br>• `Basilisk` represents hard-fork introduced in [#3056](https://github.com/nspcc-dev/neo-go/pull/3056) (ported from the [reference](https://github.com/neo-project/neo/pull/2881)). It enables strict smart contract script check against a set of JMP instructions and against method boundaries enabled on contract deploy or update. It also includes [#3080](https://github.com/nspcc-dev/neo-go/pull/3080) (ported from the [reference](https://github.com/neo-project/neo/pull/2883)) that increases `stackitem.Integer` JSON parsing precision up to the maximum value supported by the NeoVM. It also includes [#3085](https://github.com/nspcc-dev/neo-go/pull/3085) (ported from the [reference](https://github.com/neo-project/neo/pull/2810)) that enables strict check for notifications emitted by a contract to precisely match the events specified in the contract manifest. <br>• `Cockatrice` represents hard-fork introduced in [#3402](https://github.com/nspcc-dev/neo-go/pull/3402) (ported from the [reference](https://github.com/neo-project/neo/pull/2942)). Initially it is introduced along with the ability to update native contracts. This hard-fork also includes a couple of new native smart contract APIs: `keccak256` of native CryptoLib contract introduced in [#3301](https://github.com/nspcc-dev/neo-go/pull/3301) (ported from the [reference](https://github.com/neo-project/neo/pull/2925)) and `getCommitteeAddress` of native NeoToken contract inctroduced in [#3362](https://github.com/nspcc-dev/neo-go/pull/3362) (ported from the [reference](https://github.com/neo-project/neo/pull/3154)).<br>• `Domovoi` represents hard-fork introduced in [#3476](https://github.com/nspcc-dev/neo-go/pull/3476) (ported from the [reference](https://github.com/neo-project/neo/pull/3290)).

This change is implemented in the [reference](https://github.com/neo-project/neo/pull/3301), but NeoGo has never had this bug, thus proper behaviour is preserved even before HFDomovoi. It results in the fact that some T5 transactions have different ApplicationLogs comparing to the C# node, but the node states match. See [#3485](https://github.com/nspcc-dev/neo-go/pull/3485) for details on NeoGo behaviour. |
