Ethereum is a dark forest. Immutable smart contracts, financial incentives, and anonymity create an environment that forces us beyond standard security practices. Here’s how you onboard a billion users without compromising security. #securingthemission

1/7
The complexity of building a zkEVM includes the possibility of low-frequency bugs with big impact potential. That’s why zkSync has many layers of protection built into the system. Some of these security layers will fade out as the protocol moves toward full decentralization.

2/7
Instead of relying solely on one security measure, such as zero-knowledge cryptography, we implement multiple layers of protection, known as the "defense-in-depth" or "Swiss cheese model," to prevent and minimize the impact of potential breaches.

3/7
We started by implementing as many security features as we could, including centralized options such as emergency protocol freezing, a list of onboarding projects, and the ability for instant upgrades.

4/7
As trust in the system grows, zkSync will gradually reduce reliance on Matter Labs and eliminate centralized security features. For example, features like instant upgradeability will be transitioned to a decentralized security council formed of Ethereum-aligned individuals.

5/7
An example of how we phase out the security precautions is the roadmap to zkSync 2.0 Full Launch Alpha:

Phase 1: Baby Alpha (nobody but Matter Labs can interact)
Phase 2: Fair Launch Alpha (someone can interact)
Phase 3: Full Launch Alpha (everyone can interact)

6/7
Ultimately, the only forms of protection will be mathematical algorithms, computer code, and the support of the community. The security of zkSync is the responsibility of Matter Labs today, but in the future, the community will be the gatekeepers of the protocol’s security.

7/7

In this week’s #securingthemission, we’re walking through the security benefits of EVM compatibility on zkSync 2.0.

1/7
EVM compatibility is a spectrum with trade-offs between high compatibility (easy to redeploy from L1) and high performance (quick to generate ZK proofs). The more compatible with L1, the lower the performance and vice versa.

h/t: @vitalikbuterin: vitalik.ca/general/2022/0…

2/7
We designed zkSync 2.0 for high performance but specifically chose to maintain source code compatibility (Solidity and Vyper), which comes with added security benefits.

New year, same mission. With 2023 underway, we continue to be amazed by the wave of projects supporting zkSync. Here are another five updates from our fast-growing ecosystem. #jointhemission

🧵(1/7)
We recently announced that @RNS_global had integrated with zkSync for on-chain KYC. Seems like we aren’t the only fan of the world’s first sovereignty-backed digital ID, with @VitalikButerin joining the RNS.ID family.



🧵(2/7)
Following on from the initial audit from @OpenZeppelin, a second audit report from @secure3io has confirmed that our zero-compromise approach to security continues, with all initial audit findings fixed and zero critical issues so far.

In an interview with @dao_times, @anthonykrose, Head of Engineering at Matter Labs, shared some insights on how zkSync is advancing Ethereum scalability.

daotimes.com/zksync-layer-2…

Some key takeaways 1/7
zkSync is a Layer 2 rollup that uses advanced cryptography called zero-knowledge proofs to scale Ethereum without compromising on security and decentralization. zkSync is EVM compatible, which means that projects deployed on Ethereum can easily build on zkSync.

2/7
zkSync is one of the few protocols to support account abstraction. AA provides devs with additional flexibility with how they design their apps and allows for things like the development of smart wallets that can reduce the friction of interacting with a blockchain.

We’re excited to share that our team has won an award in @z_prize Open Division category for Accelerating MSM Operations on GPU/FPGA. Here’s a little bit about our submission and how we’ll use it to continue #scalingthemission.

More on our ZPrize: zprize.io/prizes/acceler…

1/5
An essential part of ZK computations is multiscalar multiplication (MSM), which needs to be fast. Our solution, built by @RoBiK @michaelcarilli achieved a latency of just 2.528 seconds and won the prize for the fastest MSM using GPUs.

2/5
Since MSM is critical to zero-knowledge computation, efficiency in this area will help zkSync 2.0 reach its true potential and unlock more use cases than we can imagine.
