zkSync是基于ZK-Rollups开发的以太坊的明星扩容解决方案。ZK-Rollups 是为第 2 层构建开发的选项之一

1.Users can sign transactions with their normal Ethereum wallets (such as Metamask or any WalletConnect one) by signing an EIP712 message.用户可以通过签署 EIP712 消息，使用他们的普通以太坊钱包（例如 Metamask 或任何 WalletConnect 钱包）签署交易。

2.zkSync's zkRollup technology combined with Eth2 data sharding is the endgame, hitting 100,000+ TPS without sacrifices on any of the 4 factors.目前的共识是Eth2 数据分片将在 2022 年底到来，以在不牺牲去中心化的情况下提供指数级更大的数据可用性层。zkSync 的 zkRollup 技术结合 Eth2 数据分片是最终目标，在不牺牲 4 个因素中的任何一个的情况下达到 100,000+ TPS。

3.Where the data is published is a tradeoff between cost and security. zkPorter transactions are exponentially cheaper than rollup transactions, but it comes with a possibility that your funds could be frozen. However, the validity of both zkRollup and zkPorter accounts is guaranteed through zero knowledge proofs and by Ethereum. In other words, funds in zkPorter can only be frozen, never stolen.数据发布的地方是成本和安全性之间的权衡。zkPorter 交易比汇总交易便宜得多，但它有可能导致您的资金被冻结。但是，zkRollup 和 zkPorter 帐户的有效性都是通过零知识证明和以太坊来保证的。换句话说，zkPorter 中的资金只能被冻结，不能被盗。

4.In zkSync 2.0, the L2 state will be divided into 2 sides: zkRollup with on-chain data availability and zkPorter with off-chain data availability.在zkSync 2.0 中，L2 状态将分为 2 个方面：具有链上数据可用性的 zkRollup 和具有离线数据可用性的 zkPorter。

5.At the same time, zkPorter has stronger security guarantees than optimistic rollups.zkPorter 比optimistic rollups汇总具有更强的安全保障
