The restart occurred after the node software was updated to version 1.6.25.
Solana blockchain stopped issuing blocks on September 14 at about 16:00 (Moscow time). The founder of the project, Anatoly Yakovenko, said that there was an exhaustion of network resources as a result of an attack of spam transactions.
“Solana’s network has seen a large increase in transaction load, reaching 400,000 TPS at its peak. These transactions overflowed the processing queue, and the lack of prioritization of critical messages led to the fact that the network began to fork, ”the developers explained.
According to them, this led to excessive memory consumption, as a result of which some nodes were disconnected.
