## zkSync

### tl; dr
|
||
|
||
<br>
|
||
|
||
* layer-2 scaling solution for ethereum, aiming for scalability.
|
||
* zkSync 2 is called Era, zkSync 1 is called light.
|
||
* uses "optimistic" transfers, which allow users to send and receive txs without waiting for conformation (reducing tx times, and allowing higher tx throughput).
|
||
* tvl: zkSync era has higher transfers of assets ($125M) than Polygon zkEVM ($2.57M)
|
||
* sybil addresses: zkSync era has more potential sybil addresses based on the depositing addresses’ wallet age and usage on Ethereum/Layer 2 networks.
|
||
* tx costs: ~$0.25-$2, high compared to optimistic rollups like arbitrum and Ootimism ($0.13 - $0.45)

### zksync era
|
||
|
||
* zksync era archtecture:
|
||
* native account abstraction (any account on era can pay fees in any tokens or even transact with zero fees on protocols willing to subsidize usage)
|
||
* powerful llvm compiler
|
||
* data compression (publishing states diffs instead of tx inputs, enabling data compression, more frequent oracle updates, cheap privacy, seamless off-chain sotrage extension)
|
||
* hyperscalability
