Ethereum has just crossed the milestone of 25 million validated blocks, without any major announcement or technical change. However, this milestone tells the story of a network valued at $278 billion, which is advancing block by block. At the same time, Bitcoin is approaching block 1,000,000, another symbolic benchmark for public blockchains and their ability to last.
In brief
- Ethereum reaches 25 million validated blocks, confirming the continuity of its network without major interruption.
- The network has been operating at a rate of approximately one block every 12 seconds since moving to proof of stake.
- ETH is moving around $2,303, for a capitalization close to $278 billion, in an accumulation phase.
- Bitcoin is approaching block 1,000,000, another symbolic milestone expected in mid-to-late 2027.
Ethereum crosses 25 million blocks without breaking
Despite recent criticism of asset management and its ecosystem, Ethereum has just crossed the milestone of 25 million validated blocks thanks to the continued work of validators. This step does not modify the protocol, but it highlights the sustainability of the network.
Since its block zero, Ethereum has never experienced a prolonged global shutdown of its base layer. However, the network has experienced several technical incidents over the years. In 2023, Ethereum stopped finalizing blocks twice in 24 hours. Each interruption lasted more than an hour.
Other episodes, in 2016 and 2020, caused partial disruptions. A bug in the Prysm client also took about 23% of nodes offline. However, Ethereum continued to produce blocks despite these difficulties.
Since moving to proof of stake in September 2022, Ethereum has targeted one block every 12 seconds. Before Merge, under proof of work, a block took more than 13 to 15 seconds. This rate represents approximately 7,000 blocks per day.
On the market, Ethereum is also moving in a calmer phase. Price action shows a contraction in volatility, characteristic of an accumulation phase. According to Coingecko data, over the last 24 hours, the price of ETH is hovering around $2,303, while the total capitalization reaches almost $278 billion. Daily trading volumes stabilize around $7.6 billion.
Bitcoin advances towards block 1,000,000
Meanwhile, Bitcoin continues its own historic journey. As of May 1, 2026, Bitcoin had approximately 947,491 blocks. There were therefore almost 52,509 blocks remaining before block 1,000,000.
Bitcoin produces an average of 144 blocks per day, or one block approximately every ten minutes. Sometimes this pace becomes slightly faster or slower. According to this trajectory, Bitcoin could reach one million blocks in mid-to-late 2027.
As for Ethereum, this milestone remains mainly symbolic. Block 1,000,000 of Bitcoin will not trigger any halving, update, or change to 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 displayed remarkable continuity. Its estimated availability rate exceeds 99.99%. This stability brings BTC closer to Ethereum on an essential point: the resilience of open networks.
Networks that build their story block by block
Each block of Ethereum bundles transactions, fees, gas data, and rewards. Under proof of stake, a block goes through a window of approximately 12 seconds. It then reaches its finality after two epochs, or approximately 15 minutes.
Block 25,000,000 of Ethereum followed this classic process. The validators finalized it by consensus, without a central authority. The Ethereum blockchain now weighs several hundred gigabytes, with tens of millions of ETH in stake.
The network has also incorporated several major upgrades. London introduced EIP-1559 and the destruction of base fees. Shanghai allowed staking withdrawals. Dencun added blobs to support layer 2 data.
These developments were deployed without interrupting block production. L2 solutions are taking a growing share of Ethereum's volume, although some have experienced outages of their own.
Ultimately, the ecosystem provides a single slot purpose. This development would reduce finalization from 15 minutes to 12 seconds. Thus, Ethereum and Bitcoin show two distinct trajectories, but the same principle: decentralized networks accumulate their history without a central operator.
