zkSync Era, a layer 2 protocol for Ethereum, has announced the launch of its new high-performance proof system called Boojum. This upgrade is designed to improve network scalability and decentralization by enabling the use of consumer-grade hardware. Boojum is a Rust-based arithmetization and constraint library that zkSync is transitioning to from its SNARK-based prover system. With Boojum, zkSync aims to significantly increase transaction processing speed and reduce transaction costs. The upgrade will be rolled out in phases on the mainnet as zkSync tests its security and functionality.

New zkSync Era Upgrade

The Boojum proof system is a key component of zkSync’s upgraded version of ZK circuits. The current SNARK-based system has limitations in scaling to high-volume, near real-time transactions. Boojum will address these limitations and enable fast finality and interoperability between Hyperchains. Additionally, Boojum will reduce hardware requirements, allowing for GPU provers with as little as 16 GB of RAM. This low barrier to entry is crucial for supporting a decentralized ecosystem. During the rollout, Boojum will be in testing mode, generating and verifying “shadow proofs” from real production data. zkSync will continue to fine-tune the upgrade’s functionality as it moves closer to full migration.

FAQ

What is zkSync Era?

zkSync Era is a zero knowledge (ZK) proofs layer 2 protocol for Ethereum. It is designed to improve scalability and performance on the Ethereum network.

What is Boojum?

Boojum is the high-performance proof system developed by zkSync Era. It is a Rust-based arithmetization and constraint library that enables faster transaction processing and improved decentralization.

How does Boojum improve network performance?

Boojum significantly increases transaction processing speed on zkSync Era, allowing for near real-time transactions. It also reduces transaction costs and enables interoperability between different Hyperchains.

How does Boojum enhance decentralization?

Boojum reduces the hardware requirements for transaction verification, allowing for the use of consumer-grade hardware. This low barrier to entry promotes a more decentralized ecosystem by enabling more participants to participate in transaction processing on the network.

Is Boojum already live?

The Boojum upgrade is currently being rolled out in phases on the mainnet. While it is live, it is still in testing mode, and the zkSync team is continuously fine-tuning its functionality.

What are “shadow proofs”?

“Shadow proofs” are proofs generated and verified using real production data on the mainnet while the Boojum upgrade is in testing mode. This allows the team to validate the functionality and security of the new proof system before full migration.

Summary

zkSync Era has launched Boojum, a high-performance proof system that aims to improve scalability and decentralization on the Ethereum network. Boojum reduces the hardware requirements for transaction verification and enables faster and cheaper transactions. The upgrade is being rolled out in phases on the mainnet, and the zkSync team is continuously testing and fine-tuning its functionality.
