❓ | Why zkSync?

zkSync Era is the layer 2 protocol that scales Ethereum's security and values through zero-knowledge cryptography. Thanks to its unique and revolutionary features, we believe it will quickly overtake the other L2s in the next few months. These are just some of the reasons we decide to build here:

Hyperscalability

zkSync Era is designed to accelerate the widespread adoption of blockchain technology by making decentralized applications more accessible and affordable at any scale. It relies on Zero Knowledge, which is a branch of cryptography that uses mathematics to calculate something called a 'zero-knowledge proof' (ZK-Proof) - which is like 'a seal of approval' to check if a given statement is true. A zero-knowledge rollup (ZK-rollup) is a way of using mathematics to verify the outcome of a transaction and compress its data down to a minimum. A proof is generated, which is double-checked for judgment, after which the trade is confirmed as being successful, and written to the underlying L1 blockchain. The advantages of this method are that it enables higher scalability (and lower gas fees), fast finality, and a high-level guarantee that the transaction has not been faked or tampered with.

Security

zkSync Era is a Layer 2 blockchain designed to scale Ethereum, it is a protocol that inherits Ethereum-level security.
zkSync Era's security model doesn't rely on game theory or fraud proofs. Instead, it is built on cryptographic and mathematical primitives. zkSync Era broadcasts its cryptographic proofs along with the information required to authenticate and reconstruct all transactions on Ethereum (L1), this ensures the security of the users' funds by making impossible to spoof or corrupt the transactions' state.

Game-changing UX

zkSync Era supports native account abstraction, giving developers UX superpowers to bring the first billion users to Web3.
By upgrading users from externally owned accounts (EOAs) to smart contract accounts (CAs) it allows users to build experiences that abstract away seed phrases, schedule and automate payments, and pay gas fees in any token — or even pay the gas on a user’s behalf. We believe this is revolutionary. A big step ahead towards mass adoption. And we want to be among the first to build on this protocol.
