|
|
|
|
Sets the maximal message size allowed by this node.
|
|
Incoming and outgoing messages with a larger size will be rejected.
|
|
Whisper message size can never exceed the limit imposed by the underlying P2P protocol (10 Mb).
|
|
|
|
##### Parameters
|
|

|
|
|
|

***
|
|
|
|
#### shh_setMinPoW
|
|
|
|
Sets the minimal PoW required by this node.
|
|
|
|
This experimental function was introduced for the future dynamic adjustment of PoW requirement. If the node is overwhelmed with messages, it should raise the PoW requirement and notify the peers. The new value should be set relative to the old value (e.g. double). The old value could be obtained via shh_info call.
|
|
|
|
**Note** This function is currently experimental.
|
|
|
|
##### Parameters
|
|
|
|
1. `Number`: The new PoW requirement.
|
|
|
|
##### Returns
|
|
|
|
`Boolean`: `true` on success and an error on failure.
|
|
|
|
##### Example
|
|
```js
|
|
// Request
|
|
curl -X POST --data '{"jsonrpc":"2.0","method":"shh_setMinPoW","params":[12.3],"id":1}'
|
|
|
|
// Result
|
|
{
|
|
"id":1,
|
|
"jsonrpc": "2.0",
|
|
"result": true
|
|
}
|
|
```
|
|
|
|
***
|
|
|
|
#### shh_markTrustedPeer
|
|
|
|
Marks specific peer trusted, which will allow it to send historic (expired) messages.
|
|
|
|
**Note** This function is not adding new nodes, the node needs to exists as a peer.
|
|
|
|
##### Parameters
|
|
|
|
1. `String`: Enode of the trusted peer.
|
|
|
|
##### Returns
