Solana Migration Overview
Following the community-driven proposal, HIP70 - Scaling the Helium Network, the Helium Network was successfully migrated to the Solana blockchain on April 18, 2023, 9am PST (16:00 UTC). This strategic move, voted in by the community, aims to capitalize on Solana's scalability, low transaction costs, and high-performance capabilities, including its fast transaction throughput and energy-efficient consensus mechanism.
The migration to Solana offers key benefits for the Helium Network: it enables the IoT and Mobile networks to support even greater scale, supports more sophisticated Proof-of-Coverage algorithms, and enhances the network's robustness, making it an even more robust solution for high-demand applications.
