❕NEWS – Maker Of Zcash Launches Educational Program For Crypto | NewProxyLists

The maker of Zcash Electric Coin Company launched a new educational training called “Crypto in Context” which will teach people about cryptocurrency. Popular exchanges like Gemini and Binance are also participating. Crypto in Context is also looking forward to hosting educational events around the world. They are planning to offer crypto lessons to the poor and needy.

verification – How to verify the signature of the Zcash message in nodejs?

It is written in many places that the t address of zcash is similar to the bitcoin address, but the bitcoin address begins with 1 or 3.
So when i try to use bitcore-message library it throws an error because it first tries to validate the address.

Is there a nodejs library available similar to bitcore-message who can verify the signature of the message?

Or any other option also works?

How to synchronize the ZCASH main network node with 100 blocks behind?

I manage a ZCASH node in a Docker container.
This error is very common during synchronization.

ERROR: AcceptToMemoryPool: inputs already spent

I learned that this is not a problem, it is just related to the confirmation of the transaction.
Because of this error, the container continues to restart and hinders other dependent tasks.

Is it possible to synchronize the node behind the main network? So that this error does not occur.

zcash – How do private transactions to recipient address in ZeroCash work from an information perspective?

In ZeroCash, they do transactions like this. I want to unravel and understand how z addresses work in ZCash. It will be described simply here and in depth, revised here and here (older, a little simpler). In other words, it will be described here:

Zerocash: decentralized anonymous payments from Bitcoin, page 11/469

or even simpler here:

Blue is what goes into the ledger, including stuff like cm, a_{pk}, sn.

So let's say we have 2 users A with T_A address, B with T_B public address.

  1. As I understand it, the randomness of the engagement doesn't seem to be stored in the blockchain?
  2. How does the recipient obtain information that they have received a coin?
  3. How? 'Or' What A and B get to know rho (randomness of serial number)?

zcash – Failed to send the transaction

Failed to send the transaction, error information: -26: 16: failure of the mandatory flag verification script (script evaluated without error but ended with a false / empty upper stack element)
what to do

How does the Zcash wallet software find its own balance if I use an armored address?

Zcash is composed of a public address and an armored address.

Armored address is perfectly hidden all transaction activities.

So, how does the Zcash wallet software (or explorer) find the balance of shielded addresses?
