### 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

|
| <a name="float" /> float | | float | float | float |
|
||
|
|
| <a name="int32" /> int32 | Uses variable-length encoding. Inefficient for encoding negative numbers – if your field is likely to have negative values, use sint32 instead. | int32 | int | int |
|
||
|
|
| <a name="int64" /> int64 | Uses variable-length encoding. Inefficient for encoding negative numbers – if your field is likely to have negative values, use sint64 instead. | int64 | long | int/long |
|

|
|
| <a name="uint32" /> uint32 | Uses variable-length encoding. | uint32 | int | int/long |
|
