bootstrap/service.proto
Service "bootstrap.Bootstrap"
Bootstrap service allows neofs-node to connect to the network. Node should perform at least one bootstrap request in the epoch to stay in the network for the next epoch.
rpc Process(Request) returns (SpreadMap);
Method Process
Process is method that allows to register node in the network and receive actual netmap
| Name | Input | Output |
|---|---|---|
| Process | Request | SpreadMap |
Message Request
| Field | Type | Label | Description |
|---|---|---|---|
| type | int32 | Type is NodeType, can be InnerRingNode (type=1) or StorageNode (type=2) | |
| info | NodeInfo | Info contains information about node | |
| TTL | uint32 | TTL must be larger than zero, it decreased in every neofs-node |
bootstrap/types.proto
Message NodeInfo
| Field | Type | Label | Description |
|---|---|---|---|
| Address | string | Address is a node multi-address | |
| PubKey | bytes | PubKey is a compressed public key representation in bytes | |
| Options | string | repeated | Options is set of node optional information, such as storage capacity, node location, price and etc |
| Status | uint64 | Status is bitmap status of the node |
Message SpreadMap
| Field | Type | Label | Description |
|---|---|---|---|
