A consensus issue with the Open Ethereum client disrupted block production a few hours after today's Berlin hard fork. The Open Ethereum team fixed the flaw some hours after it arose.
STORY CONTINUES BELOW
An open GitHub issue for the software version states there was a “node issue after Berlin hard fork, not [sic] sync after block 12244294." The GitHub page’s comments include numerous Open Ethereum users whose nodes were knocked out of sync by the bug.
The Open Ethereum software version supports 12% of nodes on the Ethereum network.
Notably, the bug did not affect nodes running Ethereum’s most used client, Go Ethereum.

Coinbase pauses ETH withdrawals
Seemingly in response to the issue, cryptocurrency exchange Coinbase has disabled ETH and ERC-20 withdrawals, according to a tweet.
A Coinbase Support alert called "Ethereum Berlin Network Upgrade" noted that withdrawals were halted from both Coinbase and Coinbase Pro. Other services that relied on Open Ethereum like the Ethereum block explorer Etherscan and custodian BitGo were also affected by the bug.
Coinbase, the largest U.S. exchange, went public yesterday through a direct listing on Nasdaq.

Updated April 15, 2021, 15:49 UTC: This article was updated to reflect that the Open Ethereum team has patched the consensus issue.

The ecosystem now spans phygital products (> $13M retail sales and >1M units sold), games and experiences (Pudgy Party surpassed 500k downloads in two weeks), and a widely distributed token (airdropped to 6M+ wallets). While the market is currently pricing Pudgy at a premium relative to traditional IP peers, sustained success depends on execution across retail expansion, gaming adoption and deeper token utility.
