One chain. One state. The speed of light.

天下武功,唯快不破主加义速

Solana cut its block time from 400 milliseconds to 200 in seven weeks, and on October 21 Alpenglow brings finality down to about 150. The creed behind that is four letters long: IBRL. Increase bandwidth, reduce latency, stop when physics says so. s/acc is the name for the people who mean it.

@anza_xyz on X, 2026-10-20: Alpenglow is pending activation on mainnet-beta.

Alpenglow goes live tomorrow, Wednesday, Oct 21 at ~14:00 UTC. One slot, and TowerBFT retires.

Migration boundary: slot 459,653,000.

24-hour countdown starts soon. Turn on notifications. 🔔@anza_xyz on X, 2026-10-19: 🚨 Alpenglow update: epoch 1064 on mainnet-beta is tracking earlier than our estimate. Slots are running faster than projected, which pulls the epoch boundary forward.

We’ll share an updated countdown time tomorrow morning once more data is in.  

Here is why timing moves. 🧵@Solana_zh on X, 2026-10-18: Alpenglow 将于 10 月 21 日周三约 UTC+8 时间 22:50 在 Mainnet-Beta 上线。

历时 18 个月的研发,只需一个 Slot 即可完成迁移。最终确认时间将从数秒缩短至约 150 毫秒。

01 Live from mainnet主网实时

400 became 200. In seven weeks.

For six years Solana's block-time target was 400 milliseconds. On August 21 it dropped to 350, a week later to 300, on September 18 to 250 and on October 9 to 200. Next is Alpenglow, live on October 21 at about 14:00 UTC. Every number below is read from mainnet while you look at it.

Block time target in milliseconds. Dates are when each cut took effect on mainnet, one epoch after its feature gate activated. Read from the gate accounts on mainnet; background: Solana Foundation, September 28, 2026. The four gates have on-chain addresses that begin with iBRL. The creed is written into the chain; watch Alpenglow's gate.

02 The Yakovenko scale延迟标尺

Kardashev measured civilizations by energy. We measure markets by latency.

Literally the goal of Solana is to carry transactions as fast as news travels around the world — so speed of light through fiber.
Anatoly Yakovenko, 2021. Source. Said about Solana, years before this coin existed.

Light circles the Earth in 133.7 milliseconds. Call that one lap. A market is as advanced as the number of laps it makes you wait before a trade is final. Press the button and wait with it.

03 The creed信条

Solana was designed around eight innovations. This is built on eight tenets.

I

Latency is the last tax.

延迟是最后一道税。

Every second you wait, someone faster gets paid. We stopped paying.

II

Increase bandwidth. Reduce latency.

增加带宽,降低延迟。

IBRL. Four letters, the whole plan. Everything else is commentary.

III

One chain. One state.

一条链,一个状态。

A market split across ten chains is ten small markets. It settles in one place or it does not settle.

IV

The floor is physics.

底线是物理。

Light needs 133.7 milliseconds to circle the planet. We stop accelerating when it does.

V

The trenches are the test.

土狗就是压力测试。

Every memecoin is a load test. The degens paid for the bandwidth and broke it in for everyone else.

VI

Chew glass.

啃硬骨头。

The hard thing, shipped. Then the next hard thing.

VII

It died at eight dollars.

它曾死在八美元。

Then it came back. A chain that walked out of its own funeral does not flinch at a red candle.

VIII

No followers. Only leaders.

没有追随者,只有领导者。

Every leader gets four slots, then the next one steps up. Same here.

Why this is a cult, and what kind.

04 Receipts加速记录

The acceleration so far.

  1. A clock before consensus

    Anatoly Yakovenko publishes Proof of History: a way for a network to agree on time without talking about it.

  2. Mainnet

    March 16. The target is a block every 400 milliseconds. It stays there for six years.

  3. A dog on Christmas

    BONK is airdropped on December 25, four days before the bottom.

  4. Eight dollars

    FTX is gone and SOL touches $8.00 on December 29. The obituaries are already written.

  5. The last outage

    February 6, five hours. Nothing since. — days and counting.

  6. First light

    Validators approve Alpenglow with 98% of the vote: finality in about 150 milliseconds, one lap of light.

  7. Fire

    Firedancer, a second client written from scratch by Jump, is announced live on mainnet in December. Its first general release follows in August 2026.

  8. Bigger blocks

    Block capacity reaches 250 million compute units a second, about twice what it was in early 2025.

  9. 29% of the stake goes dark

    A routing fault takes it offline for half an hour. Blocks keep coming.

  10. 400, 350, 300, 250

    Three cuts to the block time in four weeks, with no downtime.

  11. 200

    The fourth cut lands on October 9. A Solana Foundation review had called the 200 millisecond question "increasingly philosophical and economic, rather than purely technical." The network answered. Right now: — ms.

  12. The dawn

    Anza: Alpenglow goes live on October 21 at about 14:00 UTC, at slot 459,653,000. One slot, and TowerBFT retires: finality in about 150 milliseconds. The same week, Solana Accelerate China runs from Shanghai to Beijing.

Every line is sourced in the roadmap document and tracked in the hub.

05 The hub控制台

Everything the chain is. Everything it is becoming.

A control room for people who want the machine itself: which clients hold the stake, which release the network is on, which upgrades are live and which are waiting on a feature gate, and what shipped this week.

06 The mechanism机制

They started a think tank. We lock the fees until 2100.

The fees from e/acc go to a person, who pledged them to an institute and then wrote that e/acc is not a crypto movement. Ours go to the chain. When an epoch's fees reach one SOL they are split in half. One half is staked to an independent Firedancer validator under a lockup that runs to January 1, 2100: nobody can withdraw it before then, us included. The other half buys s/acc and burns it. A feature gate cannot change its mind. Neither can a lockup.

  1. 1

    Trade

    Every trade of s/acc pays a creator fee. The rate is pump.fun's schedule; we cannot change it.

  2. 2

    Offering

    Once per epoch, when the fees reach one SOL, they are split in half. The chain keeps the schedule.

  3. 3

    Stake and burn

    Half is staked to an independent Firedancer validator and locked until 2100. The other half buys s/acc and burns it.

  4. 4

    Validator

    The aim, never a promise: if the stake grows large enough, it gets a validator of its own.

Locked until 21000.00 SOL
Offerings0
Next offering—
EpochStakedStake accountProof
The first offering lands when this epoch closes.

What is not on chain is not claimed. Every offering links to its transaction and its stake account, which anyone can check without asking us. Holders have no claim on the stake or its rewards. Whoever holds the staker key chooses the validator, and that address is published with the first offering.

07 Take your slot认领你的槽位

No followers. Only leaders.

On Solana no leader holds the chain for long: four slots, then the next one steps up. Take yours. The slot the chain is on when you press the button is yours for good, stamped on a card you can post.
