25 million blocks validated: Ethereum quietly celebrates its longevity

Ethereum has just surpassed the milestone of 25 million validated blocks, without any major announcement or technical change. Yet this milestone tells the story of a network valued at $278 billion, moving forward block by block. At the same time, Bitcoin is approaching block 1,000,000—another symbolic marker for public blockchains and their ability to endure.

Ethereum surpasses 25 million blocks without disruption

Despite recent criticism regarding asset management and its ecosystem, Ethereum has just crossed the 25 million validated blocks mark thanks to the continuous work of validators. This milestone does not alter the protocol, but it highlights the network’s durability.

Since its genesis block, Ethereum has never experienced a prolonged global shutdown of its base layer. However, the network has faced several technical incidents over the years. In 2023, Ethereum stopped finalizing blocks twice within 24 hours, with each interruption lasting over an hour.

Other events in 2016 and 2020 caused partial disruptions. A Prysm client bug also took approximately 23% of nodes offline. Nevertheless, Ethereum continued producing blocks despite these challenges.

Since transitioning to proof of stake in September 2022, Ethereum targets one block every 12 seconds. Before the Merge, under proof of work, blocks were produced roughly every 13 to 15 seconds. This pace represents about 7,000 blocks per day.

On the market side, Ethereum is also moving through a calmer phase. Price action shows reduced volatility, characteristic of an accumulation phase. According to Coingecko data, over the past 24 hours, ETH’s price has hovered around $2,303, while total market capitalization reaches nearly $278 billion. Daily trading volume stabilizes around $7.6 billion.

Bitcoin moves toward block 1,000,000

Meanwhile, Bitcoin continues its own historical trajectory. As of May 1, 2026, Bitcoin had approximately 947,491 blocks, leaving around 52,509 blocks before reaching milestone 1,000,000.

Bitcoin produces an average of 144 blocks per day, or roughly one block every ten minutes. This pace can sometimes be slightly faster or slower. Based on this trajectory, Bitcoin could reach one million blocks between mid and late 2027.

As with Ethereum, this milestone is mostly symbolic. Bitcoin’s 1,000,000th block will not trigger a halving, update, or change in consensus rules. The next Bitcoin halving is expected at block 1,050,000.

Since its genesis block mined by Satoshi Nakamoto in January 2009, Bitcoin has demonstrated remarkable continuity. Its estimated uptime exceeds 99.99%. This stability brings BTC closer to Ethereum on a key point: the resilience of open networks.

Networks building their history block by block

Each Ethereum block includes transactions, fees, gas data, and rewards. Under proof of stake, a block is proposed within a slot of about 12 seconds. It then reaches finality after two epochs, or roughly 15 minutes.

Ethereum’s 25,000,000th block followed this standard process. Validators finalized it through consensus, without any central authority. The Ethereum blockchain now weighs several hundred gigabytes, with tens of millions of ETH staked.

The network has also integrated several major upgrades. London introduced EIP-1559 and base fee burning. Shanghai enabled staking withdrawals. Dencun added blobs to support layer 2 data.

These upgrades were deployed without interrupting block production. Layer 2 solutions now account for a growing share of Ethereum’s volume, even though some have experienced their own outages.

In the long term, the ecosystem aims for single-slot finality. This change would reduce finalization time from 15 minutes to 12 seconds. In this way, Ethereum and Bitcoin illustrate two distinct trajectories but share the same principle: decentralized networks build their history without a central operator, block after block.
