Old versions of Geth would contain network consensus flaws.
The bug was fixed five versions ago, but customers needed to update.
The ecosystem around the Ethereum project suddenly woke up this Wednesday after a division in the chain .The cause of the chain split it would be due to the delays in updating the clients of its nodes.One that stands out is that of the Infura company, which, it was known, ran an old version of the Geth client.
The situation was described by Blockchair developer Nikita Zhavoronkov, saying:
“At some point, the Ethereum developers introduced a code change that today led to a chain split starting at block 11234873 (07:08 UTC).Those who haven’t updated (@Blockchair, @infura_io, some miners and many others) got stuck on a minority chain (~ 30 blocks in 2 hours).
The programmer indicated that technically it was a hard fork or hard fork without notice.Furthermore, he questioned the situation by saying that this would be a “failure” for the Ethereum consensus, which should not be underestimated.
In his opinion, what happened is the most serious problem that Ethereum has faced since the DAO debacle 4 years ago.Infura maneuvers on what happened in Ethereum
The error generated multiple delays and drops in services since, in the case of Infura, the company offers support to various companies that do not run their own nodes, but rather use their services as an outsourced provider.
Infura issued an alert at 4:12 a.m.(Venezuela time) in which warned that they had logged a “service outage” for their Ethereum API .
At 5:47 am Infura identified the problem without offering details about what happened.However, almost two hours later he indicated the following:
“The main cause was traced to various components within our infrastructure that were locked to an older stable version of the go-ethereum client.(This) found a critical consensus bug in block 11234873, which affected several versions of Geth, including 1.9.9 and 1.9.13.Components that worked in 1.9.19 and later were not affected.

In the midst of the service recovery, Infura informed its customers that it was limiting traffic on its API gateway to “speed up service recovery.” Services stopped and user reactions
The CEO of the Binance exchange, Changpeng Zhao, posted on his Twitter account that they had temporarily suspended withdrawals, but that the funds were safe.An hour later reported that both deposits and withdrawals for ERC20 tokens had been reset.
The chief technology officer of the Bitfinex exchange house, Paolo Ardonio, made a called of attention when saying that Exchanges must run their own Ethereum nodes .On this point, Zhao himself indicated in another message that they have it on Binance, but that he was not “sure if it will be in an orphan chain.”
On reddit, users also made their views known by placing the highlighter on the topic of centralization of services.One of them was nice2yz who alleged : «What happened to decentralization? This is embarrassing for services that are not running their own nodes.
Another who intervened in the debate was eastsideski al say that ‘there are many alternatives to Infura, but most dapps (and apparently even exchanges) have been too lazy to switch.
This is a good wake-up call.
Informational services that track prices in the cryptocurrency market such as CoinMarketCap they alerted Infura was experiencing problems, which led to delays in reflecting prices.At the time of this writing, ETH, Ethereum’s native token was trading at $ 461 per unit, according to the Crypto Price Index News .Share this:.
