After four hours of outage, validators rebooted the network by blocking the so-called “durable nonce transactions” that have been popular among several exchanges.
Solana’s latest outage occurred on Wednesday when a flaw in the blockchain’s processing of a specific sort of transaction meant for offline use-cases knocked the network offline for more than four hours.
Solana Labs Communications Chief Austin Federa told CoinDesk that validators only began restarting the network after blocking these so-called “persistent nonce transactions.” They’ll be disabled until the devs figure out what caused Solana’s consensus process to go haywire and fix it.
Validators speculated that this could have repercussions for any offline custodian whose transactions fall under this category, possibly restricting their ability to move funds until the patch is applied. CoinDesk has started contacting exchanges to inquire about their Solana setup.
Even still, a few exchanges reported issues with Solana deposits and withdrawals as of publication time on Wednesday. Binance, Coinbase, and Crypto.com are three of the most popular cryptocurrency exchanges.When the outage started at noon Eastern time on Wednesday, the chain’s native SOL token was already down about 13%, trading at $39.98, according to CoinMarketCap.
Until recently, Federa said, durable nonces accounted for “an extraordinarily small percentage” of transactions on Solana. The technique is gaining traction across exchanges. A nonce is a random number that is used for a specific purpose in cryptography.
“This was likely a defect that existed for a long time but was never really an issue because it’s not something that most people use,” Federa said.
On Solana, durable nonces are meant for token holders with complicated offline signature setups who can’t always prepare their transactions quickly enough for the fast network.A custodian who signs Solana transactions using two space computers, for example, might not be able to complete the task in a single block. In this case, normal Solana transactions would fail. Nonces that last a long time offer the token holder time to work.
Solana’s ability to manage long-term nonces was tested on Wednesday. Instead of considering these specialty inbounds as a single transaction, Federa claims that the network’s validators double-counted them at two separate block heights. Solana’s consensus mechanism was effectively broken as a result of this impossible predicament.
Laine from Stakewiz, a Solana validator operator, stated the flaw was “known” and was corrected before Wednesday’s events in a tweet. They claimed that it “hadn’t been triggered in this way before.”
On Wednesday evening, important infrastructure pieces such as RPC nodes began to work again, gently bringing the network back to life.

Mixin Network Halts Services After $200 Million Security Breach; Recovery Plan in Progress
Mixin Network, a prominent decentralized wallet service provider, has been rocked by a massive security breach resulting in a loss of $200 million.
The breach, attributed to vulnerabilities in its cloud service provider’s database, has raised questions about the platform’s dependence on centralized infrastructure.
Mixin Network, known for its support of 48 public blockchains and an impressive total network asset value exceeding $1 billion, halted deposit and withdrawal services following the breach.
This incident has prompted discussions within the crypto community regarding the risks associated with centralization in decentralized platforms.
In response to the breach, Mixin Network has taken swift action, enlisting the expertise of blockchain security specialists from SlowMist.
The company has pledged to resume services only after thoroughly addressing identified vulnerabilities, a decision reached through consensus among all network nodes.
The plan for asset recovery will be announced in due course, and Mixin founder Feng Xiaodong will provide a detailed explanation in a public livestream.
The Mixin incident follows closely on the heels of the JPEX cryptocurrency exchange scandal in Hong Kong, which has left countless individuals reeling from financial losses totaling $178 million.
Experts now speculate that these recent setbacks may lead the Hong Kong government to reconsider its enthusiastic promotion of Web3 technologies, as concerns over security and public sentiment cast a shadow on the region’s cryptocurrency ambitions.
Carlton Lai, head of blockchain and cryptocurrency research at Daiwa Capital Markets, said, “I think this scandal will have a pretty sizeable negative impact on retail sentiment, given its significant local presence and the various celebrities involved.”
As Hong Kong grapples with the fallout from these high-profile incidents, the future of cryptocurrency in the region remains uncertain, with questions of regulation and security taking center stage.
Dallas Mavericks Owner and Billionaire Tech Investor, Mark Cuban, Falls Victim to Phishing Attack, Losing $870,000 in Crypto Assets
Mark Cuban, owner of the Dallas Mavericks and a prominent billionaire technology investor, recently fell prey to a phishing attack, resulting in a loss of approximately $870,000 worth of tokens.
The incident occurred over the weekend after months of inactivity on Cuban’s crypto wallet.
Phishing attacks, a prevalent threat in the crypto industry, deceive users into revealing sensitive information, downloading malicious software, and exposing their private data.
These attacks exploit users’ trust, often causing them to overlook the authenticity of incoming requests on their crypto wallets or unwittingly download counterfeit applications designed solely to pilfer their assets.
Cuban’s crypto wallet was emptied of various assets, including U.S.-pegged stablecoins, staked ETH (stETH), SuperRare (RARE) tokens, and some Ethereum Name Service (ENS) domains, according to blockchain data.
The initial discovery of these suspicious transactions was made by the vigilant on-chain investigator @wazzcrypto.
Fortunately, Cuban was alerted to these transactions, and he managed to safeguard over $2.5 million worth of Polygon’s MATIC tokens.
He accomplished this by promptly logging into his wallet and transferring the tokens to a secure Coinbase exchange address.
Cuban revealed that the phishing attack was apparently initiated through a fraudulent MetaMask wallet application that he had unwittingly downloaded.
This incident marks the second high-profile phishing attack in as many weeks, following Ethereum co-founder Vitalik Buterin’s experience in early September. Buterin’s X account was compromised in a phishing attack, although he did not appear to lose any of his own funds.
Nevertheless, unsuspecting users collectively suffered losses of up to $700,000 by sending tokens to a malicious link that falsely appeared to have Buterin’s endorsement.
As the crypto industry continues to thrive, it is crucial for users to exercise caution and remain vigilant to safeguard their digital assets from the ever-present threat of phishing attacks.
