A report by Fidelity’s Center for Applied Technology found no reported Solana mainnet outages in two years, while identifying concentration risks that could threaten the network’s resilience. According to NS3.AI, the report said concentrations in stake, hosting and client software require continued monitoring.

The report also cited progress in network health, economic security and performance. Solana reduced its slot time to 350 milliseconds, according to Jacob Creech, vice president of technology at the Solana Foundation.
