The introduction of PoSA by Fastex represents a significant development in consensus mechanisms, highlighting increased efficiency and decentralization, which has garnered substantial interest in the blockchain industry.
Paris Blockchain Week 2025 showcased Fastex and Bahamut’s PoSA consensus mechanism as a notable highlight. Pavel Aramyan, Web3 program lead at Fastex, introduced the mechanism, emphasizing its innovative approach to validator rewards.
What sets Bahamut aside is the consensus mechanism where validators have the opportunity to deploy their smart contracts and tie them directly to their validator nodes. Whenever these smart contracts are used, validators accumulate ‘activity’ — a rating influencing their chances to propose blocks and earn greater rewards. — Pavel Aramyan, Web3 Program Lead, Fastex
Fastex executives, including Armen Begdasarian, participated in the event, representing Bahamut blockchain, an EVM-based layer-1 public blockchain, and featured the Bahamut Hackathon with a €10,000 prize pool, emphasizing PoSA integration.
The event significantly impacted perceptions within the blockchain community. It introduced new opportunities for developers and blockchain projects interested in utilizing PoSA technology. 300 developers participated in the Bahamut Hackathon, indicating strong engagement.
Fastex’s initiatives at the event included products such as YoWallet and YoSim, aiming to broaden their market presence. The introduction of products and financial incentives showcases Fastex’s strategy to enhance blockchain adoption.
PoSA represents an evolution from traditional proof-of-stake systems, potentially increasing blockchain efficiency and validator activities. Historical trends and data suggest a growing preference for decentralized and efficient consensus models within the industry.
