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
Meta service.RequestMetaHeader RequestMetaHeader contains information about request meta headers (should be embedded into message)
Verify service.RequestVerificationHeader RequestVerificationHeader is a set of signatures of every NeoFS Node that processed request (should be embedded into message)

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
