| MemPoolSize | `int` | `50000` | Size of the node's memory pool where transactions are stored before they are added to block. |
| NativeActivations | `map[string][]uint32` | ContractManagement: [0]<br>StdLib: [0]<br>CryptoLib: [0]<br>LedgerContract: [0]<br>NeoToken: [0]<br>GasToken: [0]<br>PolicyContract: [0]<br>RoleManagement: [0]<br>OracleContract: [0] | The list of histories of native contracts updates. 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. |
| P2PSigExtensions | `bool` | `false` | Enables following additional Notary service related logic:<br>• Transaction attribute `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 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`). | This setting is deprecated in favor of the same setting in the ApplicationConfiguration and will be removed in future node versions. If both settings are used, setting any of them to true enables the function. |
| ReservedAttributes | `bool` | `false` | Allows to have reserved attributes range for experimental or private purposes. |
