Git: como atualizar um fork com as mudanças do original?
#!/bin/bash
# Adicione um novo remote; pode chamá-lo de "upstream":
git remote add upstream https://github.com/usuario/projeto.git
# Obtenha todos os branches deste novo remote,
# como o upstream/master por exemplo:
git fetch upstream

1. Clone your fork:

git clone [email protected]:YOUR-USERNAME/YOUR-FORKED-REPO.git

2. Add remote from original repository in your forked repository:

cd into/cloned/fork-repo
git remote add upstream git://github.com/ORIGINAL-DEV-USERNAME/REPO-YOU-FORKED-FROM.git
git fetch upstream

zkCoins: A payment system with strong privacy and scalability, combining a client-side validation protocol with validity proofs

zkCoins

zkCoins is a novel blockchain design with strong privacy and scalability properties. It combines client-side validation with a zero-knowledge proof system. The chain is reduced to a minimum base layer to prevent double spending. Most of the verification complexity is moved off-chain and communicated directly between the individual sender and recipient of a transaction. There are very few global consensus rules, which makes block validation simple. Not even a global UTXO set is required.

In contrast to zk-rollups there is no data availability problem, and no sequencer is required to coordinate a global proof aggregation. The protocol can be implemented as an additional layer contained in Bitcoin's blockchain (similar to RGB[^5] or Taro[^6]) or as a standalone sidechain.

The throughput scales to hundreds of transactions per second without sacrificing decentralization.

Design Principles

The core design principle is to *"use the chain for what the chain is good for, which is an immutable order
