Enhancement: fork and high utxos detection

[zimbora]

RPC FORK DETECTION

How to use it:

• kyanite-cli -testnet -blockchain detectfork 6

How it works

Decrements the index passed as arg to the height of active chain
Gets current hash
Gets hash of the same block using API: https://explorer.decenomy.net/api/v2/
Compares with hash returned from API
Outputs the result in the following format:

{
"nHeight": 1495956,
"remoteBlockhash": "4b19d312ace7e412b5d65d57d1cc7fa9d96597b447181e89b53b21466cdcc697",
"localBlockhash": "4b19d312ace7e412b5d65d57d1cc7fa9d96597b447181e89b53b21466cdcc697",
"requestSucceed": true,
"fForkDetected": "false"
}

RPC HIGH UTXOS DETECTION

How to use it:

• kyanite-cli -testnet -blockchain highutxos

How it works

Checks the number of utxos on wallet
Outputs the result in the following format:

{
"fHighUtxos": true,
"nUTxos": 76,
"nSpendable": 76,
"nSolvable": 76
}
