During the blackout, no funds were lost. Moreover, the network fully recovered in under 24 hours.


In a blog post on its official blog, Solana explained the cause of the network breakdown. The team said it was, in effect, a denial of service attack.


In addition, the firm explained that Grape Protocol launched their IDO on Raydium at 12:00 UTC, and bots made transactions that flooded the network.


Even more, these transactions caused a storage overflow, which made several validators crash, forcing the network to go down. This resulted from the conflict between the validator network that could not agree on the current state of the blockchain, which blocked the network from confirming new blocks.


Expanding further, Solana Foundation stressed that the community took steps to help the network recover, but was unsuccessful. The team said these transactions overwhelmed a system known as the forwarder queue, causing the memory used by this queue to grow without limits.


As a result, the transactions that were encoded into sections were resource-heavy to treat.


Moreover, the team added that the network was upgraded, and restored to full functionality in less than 24 hours. On top of that, the team said, “technical post-mortem and root cause analysis report will be released in the coming weeks."


After that, the SOL token skyrocketed to another all-time high before dropping to $140 at the time of writing.
