| CommitteeHistory | map[uint32]int | 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. |
| GarbageCollectionPeriod | `uint32` | 10000 | Controls MPT garbage collection interval (in blocks) for configurations with `RemoveUntraceableBlocks` enabled and `KeepOnlyLatestState` disabled. In this mode the node stores a number of MPT trees (corresponding to `MaxTraceableBlocks` and `StateSyncInterval`), but the DB needs to be clean from old entries from time to time. Doing it too often will cause too much processing overhead, doing it too rarely will leave more useless data in the DB. |
| 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. `Aspidochelone` is also includes [#2519](https://github.com/nspcc-dev/neo-go/pull/2519) (ported from the [reference](https://github.com/neo-project/neo/pull/2749)). It adjusts the price of `System.Runtime.GetRandom` interop and fixes its vulnerability. |
| KeepOnlyLatestState | `bool` | `false` | Specifies if MPT should only store latest state (or a set of latest states, see `P2PStateExcangeExtensions` section for details). If true, DB size will be smaller, but older roots won't be accessible. This value should remain the same for the same database. | |
| KeepOnlyLatestState | `bool` | `false` | Specifies if MPT should only store the latest state (or a set of latest states, see `P2PStateExcangeExtensions` section for details). If true, DB size will be smaller, but older roots won't be accessible. This value should remain the same for the same database. | |
| Magic | `uint32` | `0` | Magic number which uniquely identifies NEO network. |
| MaxBlockSize | `uint32` | `262144` | Maximum block size in bytes. |
| MaxBlockSystemFee | `int64` | `900000000000` | Maximum overall transactions system fee per block. |

Each list item shod be presented as a known native contract name with the corresponding list of chain's heights. The contract is not active until chain reaches the first height value specified in the list. | `Notary` is supported. |
| P2PNotaryRequestPayloadPoolSize | `int` | `1000` | Size of the node's P2P Notary request payloads memory pool where P2P Notary requests are stored before main or fallback transaction is completed and added to the chain.<br>This option is valid only if `P2PSigExtensions` are enabled. | Not supported by the C# node, thus may affect heterogeneous networks functionality. |
| P2PSigExtensions | `bool` | `false` | Enables following additional Notary service related logic:<br>• Transaction attributes `NotValidBefore`, `Conflicts` and `NotaryAssisted`<br>• Network payload of the `P2PNotaryRequest` type<br>• Native `Notary` contract<br>• Notary node module | Not supported by the C# node, thus may affect heterogeneous networks functionality. |
| P2PStateExchangeExtensions | `bool` | `false` | Enables following P2P MPT state data exchange logic: <br>• `StateSyncInterval` protocol setting <br>• P2P commands `GetMPTDataCMD` and `MPTDataCMD` | Not supported by the C# node, thus may affect heterogeneous networks functionality. Can be supported either on MPT-complete node (`KeepOnlyLatestState`=`false`) or on light GC-enabled node (`KeepOnlyLatestState`=`true`, `RemoveUntraceableBlocks`=`true`) |
| RemoveUntraceableBlocks | `bool`| `false` | Denotes whether old blocks should be removed from cache and database. If enabled, then only last `MaxTraceableBlocks` are stored and accessible to smart contracts. Old MPT data is also deleted in accordance with `GarbageCollectionPeriod` setting. If enabled along with `P2PStateExchangeExtensions`, then old blocks and MPT states should be removed up to the second latest state synchronisation point. |
| P2PStateExchangeExtensions | `bool` | `false` | Enables the following P2P MPT state data exchange logic: <br>• `StateSyncInterval` protocol setting <br>• P2P commands `GetMPTDataCMD` and `MPTDataCMD` | Not supported by the C# node, thus may affect heterogeneous networks functionality. Can be supported either on MPT-complete node (`KeepOnlyLatestState`=`false`) or on light GC-enabled node (`RemoveUntraceableBlocks=true`) in which case `KeepOnlyLatestState` setting doesn't change the behavior, an appropriate set of MPTs is always stored (see `RemoveUntraceableBlocks`). |
| RemoveUntraceableBlocks | `bool`| `false` | Denotes whether old blocks should be removed from cache and database. If enabled, then only the last `MaxTraceableBlocks` are stored and accessible to smart contracts. Old MPT data is also deleted in accordance with `GarbageCollectionPeriod` setting. If enabled along with `P2PStateExchangeExtensions`, then old blocks and MPT states will be removed up to the second latest state synchronisation point (see `StateSyncInterval`). |
| ReservedAttributes | `bool` | `false` | Allows to have reserved attributes range for experimental or private purposes. |
| SaveStorageBatch | `bool` | `false` | Enables storage batch saving before every persist. It is similar to StorageDump plugin for C# node. |
| SecondsPerBlock | `int` | `15` | Minimal time that should pass before next block is accepted. |
