Chainflow 🌞 ⚒️

Independent PoS validator since 2017

Operating on Solana, Sui, Monad, Walrus.
Self-funded, no VC.

[Chainflow 🌞 ⚒️ @ChainflowPOS]

What we watched on Sui this week as validators:
- A DoS fix shipped privately and patched fast
- Hashi getting close to mainnet
- AI agents getting limits they can’t get around

We're not done shilling London events:

The day before Breakpoint doors open, in the same building: BlockZero, a community-led validator summit run by @ChainflowPOS and friends.

Small, high-signal, built around what it actually takes to run the network. Validators, request your seat.

Monad’s security team ran the same AI model over the same codebase 4 different ways. 26 real bugs between them.

None of the 4 found all of them, and one high-severity bug only showed up in one run. Worth the read, if you use AI for audits. The latest @monad pulse is out on Substack:

When we launched chainSOL, we decided not to charge our commission on top of the pool fee. Holders already pay for liquidity, and charging twice for the same stake didn’t sit right.

So we return it every epoch, on-chain.

Did you know @ChainflowPOS was a genesis operator on Akash?

Quick question for delegators: do you know how your validator voted on the last proposal?

Most people don’t. That’s normal.
But the stake they used was yours.

If their record doesn’t match what you care about, vote yourself or move. 🌞

REMINDER: the @solana validator community call we moved is this Thursday, Oct 29, 2:00 PM ET.

Sui ran a fire drill on its new address-freeze mechanism last week. The @SuiNetwork team froze an address it controls, checked it worked, and unfroze it. Also, @DeepBookonSui just passed $20B in volume, with 15+ Sui apps trading on the same order book 👇

We’ve come a long way since Tour de Sol 🌞🏔️

We’ll be at @LuganoPlanB this Friday, and @nicostery is there for us. If you’re building on Bitcoin, or curious about our work as a Strata bridge operator, say hello or DM Nico to set up a time.

[Alpen @AlpenLabs]

Our new research moves us closer to letting anyone help secure BTC deposited on Alpen.

We survey permissionless challenging on Bitcoin & introduce polynomial soldering: a more scalable, efficient component for challenging the validity of proofs.
