Sonic: Performance Under Pressure

Sonic: Performance Under Pressure

On 10 October 2025, the biggest cryptocurrency market liquidation in history occurred. Many chains failed, slowed down, and demanded high fees. In these events, we can observe that Blockchain tech is currently made for average load, but not peak load. Sonic Labs has always been focusing on peak load. A

Inside SonicDB: Faster State Access Without the Overhead

Inside SonicDB: Faster State Access Without the Overhead

TL;DR Sonic Labs has developed SonicDB, a database that stores accounts, balances, nonces, and values for smart contracts in binary files on the file system. It utilizes a processing speed of 1,300 MGas/s on average with SonicVM on the Sonic mainnet for the first 11 million blocks.

SonicVM: There Is a Need for Speed, but Let’s Not Crash

SonicVM: There Is a Need for Speed, but Let’s Not Crash

Ethereum has established an industry standard for blockchain block processing, providing a comprehensive range of developer tools and an extensive ecosystem for decentralized applications. However, the Ethereum Virtual Machine (EVM) is known to be limited in its scalability. To enhance EVM scalability, Sonic Labs has developed a new high-performance virtual

Formal Verification for DAG Consensus Protocols

Formal Verification for DAG Consensus Protocols

TL;DR Trillions of dollars are locked into blockchains, and hackers may exploit vulnerabilities in them. Thus, key blockchain components must be well-tested before deployment. However, standard testing/audit techniques are not enough for high levels of assurance. We explore using formal verification to achieve provable security in our blockchain

Account Abstraction and the Complex Challenge of Ordering EIP-7702 Transactions

Account Abstraction and the Complex Challenge of Ordering EIP-7702 Transactions

Introduction Externally owned accounts (EOAs) in Sonic (like in Ethereum) are the most basic accounts and are controlled by a user. Most users interact with EOAs directly, typically through wallets such as Rabby, hardware wallets, etc. Currently, only EOAs can initiate transactions on Sonic, not smart contracts. The EIP-7702, proposed

Beyond Audits: Mathematically Verifying the Safety of the Sonic Gateway

Beyond Audits: Mathematically Verifying the Safety of the Sonic Gateway

TL;DR The Sonic Gateway is Sonic’s native decentralized bridge. It facilitates token transfers between Ethereum and Sonic and provides an innovative fail-safe mechanism. In case either the Gateway or Sonic experiences prolonged failures, users can recover their bridged funds on Ethereum. The security of the Gateway is paramount

SonicCS 2.0 — New Consensus for 2x Speed and 68% Memory Reduction

SonicCS 2.0 — New Consensus for 2x Speed and 68% Memory Reduction

TL;DR This article presents the new Sonic consensus protocol (SonicCS 2.0). The protocol is a DAG-based consensus protocol that overlaps elections and hence reduces space and computation effort. Moreover, our algorithm uses 0-1 matrix representations for voting structures to compute elections more efficiently. Experiments on real-world data show
