The Solana blockchain offline for 21 hours: the nightmare begins again for the SOL

Blocking – Recently, Solana’s defenders had rejoiced over a false alarm about a Polygon (MATIC) outage. But, it is the SOL blockchain that has just undergone another real problem which affected block production on the network.


Collapse of transaction rates on Solana

On February 25, Solana “ experienced a significant slowdown in block production as the Solana Compass website said at the time. These technical problems, which have begin by a fork of the blockchain around 6 a.m. UTC, would be due to a upgrade of the validation software, which went from version 1.13 to 1.14.

This update which has provoked an outage lasting more than 9 p.m. would be the cause of the collapse in the flow of on-chain transactions. According to data from Solana Explorer, the network was processing approximately 93 transactions per second at 7:00 UTC, while recording 5,000 transactions per second 15 minutes earlier.

Although validators and engineers suspected a bug in the updated version of Solana’s code, they were unable to precisely identify the source of the problem. Validators then decided to revert to version 1.13 to try, unsuccessfully, to restore the performance of the blockchain. The validators had to restart the network, with version 1.13.6.

Blocking transactions on the SOL blockchain: the time of decentralization

Restarting the network is a drastic solution that takes time. In fact, this operation requires the intervention of 80% of validators active online. Getting back to normal took hours. But, the reboot itself is not the only factor that extended the duration of the transaction block.

Debates over which software version to run are also responsible for this blockchain paralysis. But although ” user transactions are not processed during this period of exchanges, the infrastructure provider Chorus One sees the positive side, indicating in its tweet of February 25, that these discussions are the ” testimony to decentralization in Solana, and also the costs of decentralization “.

At the time of writing this article, Solana Compass noted that the network working again ” and ” it may take a few minutes for the RPC nodes of the different applications to recover “.

With this slowdown in transactions on the network, Solana is (already) having technical problems this year. In the month of January, RPC endpoints, which the Solana Foundation manages, were offline.
