Fantom's Sonic: Revolutionizing Blockchain Scalability
This pioneering effort was spearheaded by Andre Cronje. He meticulously applied advanced concepts like Concurrent Common Knowledge (CCK) and Lamport Timestamps.
The result was a groundbreaking achievement: the first permissionless Directed Acyclic Graph (DAG)-based protocol. It dramatically improved scalability and reduced time to finality.
DAG Breakthrough: Transforming Scalability
Opera could achieve a maximum throughput of approximately 200 transactions per second (TPS) and boasted a time to finality of under 600 milliseconds. This was a stark contrast to Ethereum’s capacity of 12 TPS and finality times exceeding 60 seconds at that time.

The Opera network’s growth was rapid and impressive.

Starting from zero users, it evolved into one of the most recognized and widely used networks, with a total value locked (TVL) exceeding $10 billion by 2022. However, this explosive growth was not without its challenges. During periods of high demand, the network experienced congestion, leading to a degraded user experience.

In response to these growing pains, the Fantom team has dedicated the past two years to developing a revolutionary new technology called Sonic. Sonic is designed to be the most scalable and secure blockchain technology to date. Its ability to process 2,000 TPS with sub-second finality marks a significant advancement from Opera’s capabilities. The team takes great pride in Sonic’s potential to redefine blockchain performance and user experience.

Sonic’s impressive technical capabilities signal the beginning of a new era for the network. The technology will be harnessed to create a new, best-in-class shared sequencer for Layer 1 (L1) and Layer 2 (L2) chains. This sequencer is expected to handle over 180 million daily transactions with genuine sub-second confirmation times.

This leap in performance will serve as the foundation for relaunching Fantom as a community-centric brand, emphasizing both innovation and user experience.
