Hi, Bradley Keoun here, editor of The Protocol.
When the Ethereum blockchain temporarily stopped finalizing transactions last week, a sense of panic spread across Crypto Twitter. In today’s feature, our Margaux Nijkerk explains how Ethereum’s mini-crisis over transaction “finality” unfolded and why top developers on the blockchain aren’t too worried.
In the news, we’re covering Bitcoin’s existential struggle with congestion-inducing “BRC-20” tokens – and, yes, now “DRC-20 tokens” on Dogecoin. Ledger’s crypto wallet recovery service has spurred an outcry (and lots of suspicions), Ripple agreed on a $250 million deal, and crypto projects raised more than $60 million.
Ethereum Briefly Stopped Finalizing Transactions – What Happened?
There was a lot of confusion in terms of what the delay in “finality” meant for the functionality of the blockchain, prompting discussions about security concerns. So it bears unpacking a bit.
The cause of the temporary loss of block finality remains under investigation, though Prysm, a provider of client software used to run a node on the blockchain, just released a new version, describing it as “the first full release following the recent mainnet issues,” with “critical fixes.”

When data blocks don’t finalize, there isn’t supposed to be any downtime or difference in end-user experience. That said, a loss in finality can lead to some security issues like reorgs.
Reorgs occur when a blockchain produces more than one block at the same time, usually because of a bug or an attack. This means that a validator node temporarily creates a new version of a blockchain, which makes it difficult to properly verify if a transaction has been successful, while the old version of the blockchain continues to exist.
However, snowball effects from this incident led to some end-user jolts. DYdX, a leading crypto exchange platform, had to temporarily pause deposits because of one of last week’s incidents, and Polygon’s zkEVM also experienced some delays with deposits.
On Ethereum, there’s not just a wait to get out, but a wait to get in. After last month’s “Shapella” upgrade allowed validators of the blockchain to make full withdrawals of their 32 ETH ($58,400) stake for the first time ever, the world learned just how long it can take to actually exit – a queue as long as 17 days at one point. What’s now jolting Ethereum watchers is just how long it can take to establish a new validator. Currently, the queue stands at 640 hours, or 26 days – nearly a month. The wait times are a function of Ethereum’s own design choices, which impose hard limits on inflows and outflows, to help stabilize network security. But staking apparently isn’t for fast money.
Say it out loud: ‘Dencun.’ Ethereum developers are already planning the next big upgrade, which they’ve named using a Brangelina-style portmanteau similar to the recently completed “Shapella.”
Worldcoin, crypto project of Open AI co-founder Sam Altman, reportedly raises $100M from Andreesen Horowitz, Khosla Ventures, through sale of tokens.

Here we highlight some of the latest blockchain tech upgrades:
Balancer, an automated market maker, is set to play a crucial role in a coordinated effort to recover $300,000 of frozen cryptocurrencies – before arbitrageurs can lay claim.
Bakkt, crypto trading platform controlled by Intercontinental Exchange, delists 23 tokens, citing “up-to-date regulatory guidance.” They include Aave (AAVE), Avalanche (AVAX), Chainlink (LINK), Cosmos (ATOM), Filecoin (FIL), Maker DAO (MKR), Stellar (XLM) and Uniswap (UNI).
Data Corner
The chart below shows the Bitcoin blockchain’s “mempool” – the backlog of transactions waiting to be confirmed. The mempool surged to a record 480,700 transactions recently, according to Jochen Hoenicke’s website, as the explosion of BRC-20 tokens minted using Ordinals inscriptions backed up the network. Bitcoin miners have worked down the mempool by roughly half from where it was, but the absolute level is still well above the sub-100,000 unconfirmed transactions that prevailed for most of the past couple years.
