Reliably unreliable: Solana price dives after latest network outage

The Solana network is not having a good year, having suffered full or partial outages at least seven separate times over the past 12 months.A bug has knocked the Solana blockchain offline again as block production halted at 16:55 UTC on June 1. This latest outage lasted around four and a half hours as validator operators managed to restart the mainnet at around 21:00 UTC, according to the incident report.Validator operators successfully completed a cluster restart of Mainnet Beta at 9:00 PM UTC, following a roughly 4 and a half hour outage after the network failed to reach consensus. Network operators an dapps will continue to restore client services over the next several hours.— Solana Status (@SolanaStatus) June 1, 2022Solana Labs co-founder Anatoly Yakovenko explained what happened in a tweet:“Durable nonce instruction caused part of the network to consider the block is invalid, no consensus could be formed.”‘Durable transaction nonce’ refers to a mechanism addressing the typical short lifetime of a transaction block hash according to the official Solana documentation. A bug in the feature caused nodes to generate different outputs resulting in consensus failure, which ultimately caused the latest period of downtime.The network was restarted with this feature disabled, and Yakovenko added that fixes for the bug “will be out ASAP.”Naturally, there was a fair amount of backlash from the community with comments like this filling up its feed:“Get it together Solana. We should be past this already. I’m big believer but I’m even doubting at this point.”CNBC crypto trader and Onchain Capital CEO Ran Neuner simply quipped:BREAKING: SOLANA.— Ran NeuNer (@cryptomanran) June 1, 2022

SOL prices have taken a massive hit tanking almost 14% over the past 12 hours or so in a fall below $40, according to CoinGecko. The network native token has now slumped 85% from its November 2021 all-time high of $260, and it is poised to slip out of the top ten by market ca.SOL/USD 24hr – coingecko.comSolana, which has often been dubbed an “Ethereum killer,” has been fully or partially offline at least seven times since September 2021, when it suffered denial of service attack-related outages twice in the same month, according to the network uptime tracker.The blockchain was plagued with problems in January when it suffered service disruptions and degraded performance for nine days out of the 31 in the month. Duplicate transactions were blamed for the second outage in January. In late April and early May, Solana was down again for almost 8 hours due to NFT minting bots overwhelming the network.Related: Solana suffers 7 hour outage as bots invade the networkAdditionally, Solana’s blockchain clock is slow and running 30 minutes behind real-world time. The status page notes “On-chain time continues to run behind that of wall clocks, due to longer-than-normal block times.”

Polygon upgrade quietly fixes bug that put $24B of MATIC at risk

Ethereum-based layer two scaling network Polygon has quietly fixed a vulnerability that put almost $24 billion worth of its native token MATIC at risk. According to a Dec. 29 blog post from Polygon, the “critical” vulnerability in the network’s Proof-of-Stake (PoS) Genesis contract was first highlighted by two whitehat hackers on Dec. 3 and Dec. 4 via blockchain security and bug bounty hosting platform Immunefi.All you need to know about the recent Polygon network update.✅A security partner discovered a vulnerability✅Fix was immediately introduced✅Validators upgraded the network✅No material harm to the protocol/end-users✅White hats were paid a bounty https://t.co/oyDkvohg33— Polygon | $MATIC (@0xPolygon) December 29, 2021The vulnerability put more than 9.27 billion MATIC at risk that is valued at around $23.6 billion at the time of writing, with the figure representing the vast majority of the token’s total supply of 10 billion. Polygon noted that the bug was resolved at Block #22156660 via an “Emergency Bor Upgrade” to the Mainnet on Dec. 5 at around 7:27 am UTC. The network noted that a “malicious hacker” managed to steal 801,601 MATIC ($2.04 million) before the bug was resolved. The blog post said:“The Polygon core team engaged with the group and Immunefi’s expert team and immediately introduced a fix. The validator and full node communities were notified, and they rallied behind the core devs to upgrade 80% of the network within 24 hours without stoppage.”Polygon stated that the issue was fixed behind closed doors as it follows the “silent patches” policy introduced by the Go Ethereum (Geth) team in November 2020. Under the guidelines, projects or developers report on key bug fixes 4-8 weeks after they go live to avoid the risk of being exploited at the time of patching. According to Immunefi, Whitehat hacker “Leon Spacewalker” was the first to report on the security hole on Dec. 3 and will be rewarded with $2.2 million worth of stablecoins for their efforts, while the second unnamed hacker, referred to as “Whitehat2” will receive 500,000 MATIC ($1.27 million) from Polygon.Related: Here’s how Polygon is challenging the limitations of Ethereum, as told by co-founder Sandeep NailwalPolygon’s co-founder Jaynti Kanani emphasized the network’s ability to promptly resolve the critical bug, noting in the blog post that: “What’s important is that this was a test of our network’s resilience as well as our ability to act decisively under pressure. Considering how much was at stake, I believe our team has made the best decisions possible given the circumstances.”According to data from Coingecko, MATIC is priced at $2.45 and is up 35.1% over the past 30 days despite the current downturn across major crypto assets this month.
