The Solana ecosystem is entering a new phase of its development: the development team has launched the process of reducing block generation time from 400 to 200 milliseconds. The first stage of this large-scale upgrade will start at epoch 1020, within one of the two-day windows allocated for network changes.
The Agave client, developed by the Anza team, supports all four stages of the transition. Each of them is activated separately, allowing validators to carefully control the process. Upon completion of all phases, the network will produce a new block every 0.2 seconds, effectively doubling the current throughput.
Doubling blocks per second: technical details
Currently, Solana generates about 144 blocks per minute, which is slightly more than two blocks per second. With the transition to a 200 ms interval, this figure will rise to 300 blocks per minute. It is important to emphasize: the acceleration will not lead to increased network load. Block sizes will be proportionally reduced, so the total volume of processed data will remain unchanged.
The developers have divided the transition into four stages with a step of 50 milliseconds. Validators retain the ability to stop the process at any moment if the network begins to lose too many blocks. That is why Anza calls this schedule preliminary — flexibility remains a priority.
According to data from a dedicated page, 96.7% of staked coins have already been updated to the required software version. 690 validators are participating in the upgrade, and 435 million SOL are in active staking.
Stability as a key challenge
The main question is operational stability. In August, the Solana network was on the verge of a halt: due to a routing failure, 28.83% of staked SOL went offline. Validators also slowed the implementation of an emergency patch scheduled for early 2026. These incidents serve as a reminder that speed is not the only criterion for efficiency.
Comparison with Bitcoin and Ethereum
The contrast with other blockchains is impressive. Bitcoin produces a block every 10 minutes, while Solana at a 200 ms interval will create 3,000 blocks in the same time. Ethereum adds a new block approximately every 12 seconds — Solana already updates the chain 30 times more often, and after the transition, this gap will grow to 60 times.
However, the real settlement speed looks different. A transaction on Solana receives final confirmation in about 13 seconds. Ethereum takes about 13 minutes for the same operation, and Bitcoin about an hour. The second half of the task is addressed by the Alpenglow mechanism — a new consensus with finalization in 150 ms, the first phase of which is planned for implementation in the third quarter alongside the release of Agave 4.3.
Market reaction and prospects
Solana co-founder Anatoly Yakovenko compared the pace of the upgrade with previous experience. "The transition from 800 ms to 400 ms took 2 days," he noted. This sets a benchmark for subsequent stages, although Anza has not yet announced exact dates.
The price of SOL is near the $90.7 mark. The token's growth over the week exceeded 20%. The coin ranks seventh by market capitalization — $52.91 billion.
My view: Accelerating blocks is a logical step for Solana, which seeks to strengthen its status as the fastest network. However, the history of the August failure shows that each stage must be accompanied by careful monitoring. The success of this upgrade will be a test not only for the technical team but also for the entire ecosystem, which increasingly depends on the speed and reliability of the base layer.
