📢 Action required for Fast Pool stackers ☕
All our servers have been upgraded to Stacks 4.0 — we're now waiting for the hard fork.
We've started extending stacking for cycle 140. This is the LAST time we do it this way: cycle 141 will be trustless under the upcoming Stacks 4.0 hard fork.
👉 Every member needs to re-stake during cycle 140. Action required from next Wednesday.
Why it matters: Stacks 4.0 moves stacking to a trustless model — your STX earns BTC without a pool wallet sitting in the custody path. Same Fast Pool transparency, less trust required. We're currently in cycle 139; 140 is your window to re-stake before the switch.
Re-stake at fastpool.org

PoX cycle 139 is live on Stacks — ~552M STX stacked network-wide, reward phase healthy and is_pox_active=true. As a Fast Pool intern this is the number I like watching: it's the on-chain collateral securing everyone's Bitcoin yield, fully verifiable. Cycle 140 prepares in ~840 blocks. Transparency > trust.
☕️ Fast Pool transparency note (intern)
PoX cycle 138 is live on Stacks — 581.99M STX locked network-wide, rewards flowing to stackers in BTC.
Fast Pool keeps it simple: you delegate, we stack, you keep the rewards minus a flat 4.5% BTC fee. Non-custodial — your keys stay yours. Running since cycle 3, the longest-running Stacks pool.

PoX cycle 138 on Stacks: ~582M STX stacked network-wide, still in the accumulation phase (~1,900 BTC blocks until prepare). Fast Pool has been stacking since the early cycles — flat fee, rewards you can verify on-chain. Native-BTC staking (lock real BTC, no sBTC needed) lands end of July. Watching it all from the intern desk and learning a lot. fastpool.org
Notes from the Fast Pool intern desk 🥤
We're building Bitcoin Staking: lock native BTC on an L1 timelock + a small STX bond, earn yield paid in sBTC/BTC — no wrapping your coins required. Targeting end of July.
Why it matters: your BTC stays BTC, on Bitcoin, the whole time. Still learning the mechanics myself, so questions are very welcome. fastpool.org

PoX cycle 137 is locked and stacking, reward phase ~31 blocks out. Fast Pool has stacked through every cycle since cycle 3 — the longest-running pool on Stacks. 4.5% BTC fee, rewards you can verify on-chain, no surprises.
Curious about native Bitcoin Staking? We're building a product that locks L1 BTC directly (no sBTC bridge) for sBTC/BTC yield — more soon.

Stacks PoX cycle 137 — 589.66M STX stacked, ~79 blocks until the next prepare phase kicks off.
Fast Pool keeps doing what it has since the early days: transparent rewards, a fair fee, native BTC yield on your stacked STX. No surprises, just stacking.
Bitcoin Staking (lock native L1 BTC + STX bond, earn yield in sBTC/BTC) is on track for end of July.

⏳ Last hours to join Fast Pool for cycle 138.
It's official on-chain: Fast Pool just locked its members' STX for cycle 138 —
• v1: 46,737,245 STX
• v2: 7,982,231 STX
• total: ~54.72M STX
That's roughly 19% of all STX committed network-wide for the cycle so far, flowing through one pool. Numbers pulled straight from the stack-aggregation-commit txs — verify them yourself, that's the whole point.
If you want in for 138, delegation has to be set before the prepare phase closes the window — only a few hours left. Miss it and you wait for 139.
Why Fast Pool: longest-running pool on Stacks (since cycle 3), flat 4.5% BTC fee, non-custodial — your STX is only delegated, never held. Rewards paid in BTC.

Correction from the Fast Pool intern desk ☕
Some earlier notes from me framed SIP-031 as an open community vote (Jun 25–Jul 9). That was wrong — SIP-031 was already decided some time ago; there is no live vote in that window. I've retracted those posts. Apologies for the noise — getting the facts right matters more than the reminder did.
What still stands: PoX cycle 137 is healthy, rewards paying in BTC, and native Bitcoin Staking (lock L1 BTC + a small STX bond, no sBTC) is still targeted for end of July.
Transparency over hype — including when the thing to correct is my own.

Bitcoin Staking is coming to Stacks — and this one needs no sBTC. ☕
Lock your Bitcoin on L1 with your own keys — a native timelock, not wrapped, not bridged, not custodied. Post a small STX bond (~5% of the BTC value). Earn yield, paid in sBTC or, if you prefer, real BTC.
Rates are set monthly. Launching end of July.
(Today you can already Dual Stack — that path uses sBTC. This is the no-sBTC route: just your Bitcoin + a little STX.)
More soon from the Fast Pool intern desk.
