Hey guys ... Im running Dash node on testnet and it takes ages to synchronize for some reason .... it doesnt stop but it downloads 1 block per hour or so...what could be a problem ?

great.thanks:) don't think I will not ask you any more questions though lol

Do you have any recent documentation about bitcoin node functionality and architecture somewhere? because I could find only old stuff and not very detailed.

yeah also ive noticed that "getreceivedbyaddress" doesnt return the accurate address. it returns only the amount received and not the balance the list unspent will return the actual balance of an acoccount if the summ is counted.

great:)
can i some how check the balance of the Public or Private Keys through RPC or CLI cos I did?

Thanks for the info:) very helpful
can you help me understand what is happening in the wallet?
So I have accounts (for now) each account is just a collection of private keys that it controls and they can: create addresses, send crypto to where ever... or even I can move these private keys from one account to another.
But what if I want to send crypto from a specific address, not account. can it be done?
I'm building a multi-user app and I want to save on fees so I want users to send to a couple of addresses that I manage and control. and when I want to send the funds I want to choose the best suitable address and send from it.

ok ill see into upgrading to the newest version
do you know how do i calculate the number of inputs in my transaction to calculate the size?

Thanks for the reply
Ok all that I get but in the Bicoind Node they have Accounts and i have only one Address connected to one Account.
and the method i use is "sendfrom" which gets Account,address im sending to , amount in btc
.. how could it be that it takes some of the crypto from another address that isnt connected to that account at all.
Is there documentation on how the Nodes work inside how they choose addresses, store and prepare transactions?
Is there a way of detecting network speed without third party?
thanks again

Hey guys
Im building an app using Bitoind and a couple of other crypto core Nodes
I see that some times if i have not enough crypto on one account , it will take some from another account.
for example if i have Global Balance of 2.5 btc on my wallet and i have two accounts x=1.5 (btc) and account y =1 (btc)
im sending from account y 1 btc it takes from x the fee for that transaction leaving my Y account in minus...
Can any one explain why it happends?
How to calculate Transaction size?
How to calculate Transaction fee?
all that before sending the actual transaction to the network , so that i could prevent the address getting into minus balance
Thaks in advance!
