Скрипт вывода статистики с криптокошельков

Используется jsonRPCClient.php отсюда

Полезная инфа, использованная для написания

getnetworkinfo:

version - идет в формате 6-7 чисел. Можно сделать обработку и делить точками (123456 => 0.12.34.56 или 1234567 => 1.23.45.67), но нова выбивается.
connections - альтернатива - вызвать getconnectioncount

-------------------------------

getblockchaininfo:

blocks - альтернатива - вызвать getblockcount
difficulty - альтернатива - вызвать getdifficulty
verificationprogress - домножить на 100 и округлить до 2-3 знака после запятой

-------------------------------

getmempoolinfo:

size - число транзакций
usage - байты. Делить на 1024/1024
usage/maxmempool - заполненность. Умножить на 100 и округлить до пары знаков.

-------------------------------

uptime - время работы кошелька (секунды)

-------------------------------

getmininginfo

тоже можно взять blocks и difficulty, как в getblockchaininfo, плюс есть число транз - pooledtx, есть скорость сети - networkhashps

-------------------------------

getnettotals:

totalbytesrecv - получено, байт
totalbytessent - отправлено, байт

-------------------------------

estimatesmartfee - комиссия. Аргумент - число блоков.

==============================================================
Особенности:
getmempoolinfo: Doge не отдает максимум (т.е., не можем знать процент) и usage, только bytes (бесполезно) NVC не отдает ничего.
uptime: не умеет никто, кроме btc
getmininginfo: difficulty на нове - массив для PoW и PoS. Скорость сети на нове зовется netmhashps вместо networkhashps.
estimatesmartfee: Doge и Нова не умеют. Для остальных - массив данных; забирать feerate
getblockchaininfo: все, кроме Новы. Нова не умеет ничего, кроме difficulty, но почему-то не отдает его через API.
getnetworkinfo: все, кроме новы. Нова не умеет метод.
