Shardeum Launches Mainnet: A New Era in Blockchain Scalability

Shardeum, an innovative Layer 1 blockchain, successfully launched its Mainnet on May 5th, 2025, marking a significant milestone in its mission to solve the blockchain trilemma. Following a highly successful testnet phase that attracted over 1.4 million participants and set a record with 171,000 validators, Shardeum transitions from research to a live network, offering decentralization, scalability, and affordability without trade-offs.

Key features of the Mainnet include a permissionless validator network, starting with 256 validators, and the ability for anyone to spin up a node in under a minute. Autoscaling ensures transaction throughput increases with validator participation, maintaining gas fees as low as $0.01 even during congestion. Dynamic state sharding and the proprietary Proof-of-Quorum Optimistic (PoQo) consensus mechanism enable near-infinite scalability.

Post-launch, Shardeum will introduce an innovative validator accountability system, avoiding traditional slashing penalties. The network is open-source, with 60+ repositories and significant community engagement on GitHub. EVM compatibility ensures seamless integration with major wallets like MetaMask, making it developer-ready.

Backed by prominent investors and partners, Shardeum reinforces its credibility with a transparent roadmap. The total circulating supply of SHM is 249 million, with token generation and listings aligned with Mainnet rollout. Future plans include smart-contract functionality testing and stable dApp deployments, supported by global community events.

Shardeum's Mainnet launch signifies a shift from vision to reality, offering a live, permissionless, and user-friendly blockchain environment. With a focus on transparency and community-driven evolution, Shardeum empowers developers, validators, and users to participate in a scalable and decentralized ecosystem.
