Welcome!
In this lesson, we will teach you the basics of zkSync, by walking you through setting up a shop where a customer (Alice) can buy goods from a shopkeeper (Bob)
Recently there’s been some interesting research on using zero-knowledge proofs to secure token transfers between Ethereum and side-chains, and there’s now a practical implementation of this research in the form of zkSync from Matter Labs.
zkSync is built on the ZK rollup architecture, a level-two scaling solution in which all funds are held by a smart contract on Ethereum, while computation and storage are performed off-chain.
This is the short answer to why we think zkSync is important:
- The protocol allows ETH and ERC20 token transfers with instant confirmations and 10 min finality on Ethereum.
- Provides Mainnet-level security with zero reliance on 3rd parties.
- Low transaction fees
- Fast deposits and withdrawals
In a nutshell, users can send their ETH or ERC20 tokens to the zkSync smart contract on Ethereum, and the protocol will credit them with the equivalent assets. For simplicity, this tutorial will only cover how you can make ETH payments.
By the end of this lesson, you will be able to:
- Set up accounts on zkSync
- Deposit ETH to zkSync
- Make payments by transferring ETH between zkSync accounts
- Track the status of these transactions.
- Withdraw ETH to Ethereum
Let's get started!
