Did some digging today on an interesting question: which Layer 1 blockchains have maintained the best uptime records since their inception? Here's what the data shows.
On the EVM side, Ethereum stands out with a perfect 100% uptime track record from day one. Meanwhile, Fantom, Sonora, and TRON have each maintained an impressive 99.99% uptime—essentially flawless performance with only minimal downtime across their entire history.
Looking at non-EVM L1s, the picture is equally solid. Cardano, Litecoin, and Dogecoin have all achieved 100% uptime since launch, demonstrating the reliability of their underlying infrastructure. These metrics highlight why uptime remains one of the most critical factors when evaluating Layer 1 blockchain networks—it's the foundation that everything else is built on.
