Why Bridge to zkSync? Understanding the Benefits

zkSync is a Layer 2 network that scales Ethereum with the latest, cutting-edge ZK technology. It was developed not only to increase Ethereum’s throughput, but also to fully preserve its foundational values of freedom, self-sovereignty, and decentralization at scale. According to zkSync, their endgame is ‘hyperscalability’. This is because in order to meet web3’s ever-increasing and exponential demand, blockchains need to be able to scale like the web2 Internet—able to process an unlimited number of transactions, without marginal impact on security or cost.

zkSync is built on zero-knowledge (ZK) rollup architecture, an L2 scaling solution in which all funds are held by a smart contract on the mainchain, while computation and storage are performed off-chain. A state transition zero-knowledge proof (SNARK) is generated and verified by the mainchain contract for every rollup block. This SNARK includes the proof of the validity of every single transaction in the Rollup block. 

Thus, ZK rollup architecture provides the following guarantees:

  • The rollup validator(s) can never corrupt the state or steal funds
  • Users can always retrieve the funds from the Rollup even if the validator(s) stop cooperating because the data is available
  • Because of validity proofs, neither users nor a single other trusted party needs to be online to monitor rollup blocks in order to prevent fraud

Tl;dr, ZK rollup inherits the security guarantees of the underlying L1—in this case, Ethereum. zkSync thus enables users to enter and exit the Ethereum mainnet in a decentralized pattern, all while offering lower transaction fees.

How to Bridge to zkSync? Why is the zkSync Official Bridge not the Best Choice?

In most cases, the zkSync official Bridge will probably be the top-of-mind or simplest way to transfer assets to zkSync. However, it does have a few drawbacks:

  • The zkSync official bridge facilitates asset transfers exclusively between Ethereum and zkSync only—excluding connectivity with other Layer 1 or Layer 2 networks
  • The wait time for withdrawals is too long, requiring a 24-hour processing period

Having noted these limitations, you can begin thinking about using third-party cross-chain bridges to transfer your assets to zkSync. Luckily, XY Finance provides an easy, user-friendly, and efficient way to do just that.
