Solana Developers Are Tackling Bugs Hoping To Prevent Further Outages

Must Read


Solana developers are tackling bugs that hope to prevent network outages in the future so let’s have a closer look at today’s latest blockchain news.

Solana developers are tackling bugs that knocked the network offline for the fifth time this year. The developers fixed the runtime bug which caused the latest outrage of the network on June 1. According to the reports by Solana Labs, the fifth outage of 2022 was caused by the bug in the durable nonce transactions feature which caused the network to stop producing blocks for four and a half hours:

“The durable nonce transaction feature was disabled in releases v1.9.28/v1.10.23 to prevent the network from halting if the same situation were to arise again. Durable nonce transactions will not process until the mitigation has been applied, and the feature re-activated in a forthcoming release.”

The term durable nonce transactions is a type of transaction on Solana which is designed to not expire unlike the normal transaction on the network which usually has a short lifetime of 2 minutes before the block hash is too old to be validated. It is used to support transactions related to avenues like custodial services which require more time than usual to produce a signature for the transaction. Solana Labs noted that these transactions require a separate mechanism to prevent double processing and are processed serially but the runtime bug presented after a durable nonce transaction was processed as a regular transaction and then failed but was resubmitted again and resulted in a network halt:

“After the failed transaction was processed, but before the nonce was used again, the user resubmitted the same transaction for processing. This resubmission activated the bug in the runtime.”

The price of Solana’s native asset SOL dropped by 13% since the mainnet outage at the beginning of June to a price of $39 at the time of writing. The investors’ appetite to trade the asset increased but the 24-hour trading volume increased by 61%, to $2.141 billion within the same time frame. In the broader sense, the data from the Solana platform Hello Moon shows that the total value moved on-chain in terms of a seven-day rolling average whcih dropped in late March. After topping out ATH levels of around $3.18 trillion, the figure dropped to around $159 billion.
