Scaling PoW was just the beginning. Now we build the flywheel. Alignment begins. 🌀.

My dad always told me "watch out where you put your signature and your. " 🤫. Both Alephium mobile and desktop wallet now display the simulated output of a transaction during signing, before you sign it. This is safer than blindly signing a bytecode.

Code editors should show you which lines were written by AI vs. humans. Would change how we review, debug, and even trust code.

Now is the time to activate. As the ecosystem grows, every builder benefits. Alignment strengthens the network, the network strengthens opportunities. The next era of Alephium begins! Stay close.

No hype cycles. No empty promises. Value loops that sustain themselves through usage, staking, and deflationary tokenomics. Composability. Sustainability. Deflation by design.

Phase 2: Alignment. An economy that rewards participation, not extraction. Staking as the network’s heartbeat, powered by transaction fees from a Core dApp and ecosystem synergies.

Phase 1: Infrastructure. • Native sharding → real scalability.• Security → grounded in proven principles.• Dev experience → Web2-grade.

While others chose PoS, we scaled PoW. Scaling without sacrifice. Performance without trade-offs. A single, coherent Layer 1, secure, composable, reliable. This isn’t a promise. It’s live. Tested. Proven.

Alephium is stable again, but the situation is still developing. An official update and full post-mortem will follow soon. Thanks for your support and patience. Onwards 🔥.

The incident lasted about 24 hours. Several core contributors barely slept. Big thanks to Maud, Hongchao, Muchen, and others who jumped in. And to the community: your alerts and feedback were incredibly helpful.

What did we learn?. ✅ The DAA (Difficulty Adjustment Algorithm) behaved as intended.⚠️ But the penalty curve was too steep in practice. We’ll be refining it in the future, keeping its core purpose but softening the edges.

A few hours later, we connected with the right pool. They responded quickly, updated their mining strategy, and pushed the change to production shortly. Roughly 10 hours later, difficulty levels is back to normal on their own.

With Maud’s help, we reached out to pools to confirm the behavior. It was a Friday night. No replies at first. So we kept going: digging into block data, identifying patterns, and preparing backup plans.

Then Muchen joined, freshly awake, and we quickly pinpointed the issue. A large hashrate was repeatedly mining only one chain at a time. That behavior triggered the penalty again and again, causing difficulty to spike rapidly.

The idea is simple: if too much hashrate ends up on one chain, a penalty kicks in and raises the global difficulty. But in hindsight, the penalty factor might’ve been too aggressive in certain edge cases. We started asking: do we need an emergency upgrade to change that?.

Hongchao quickly pointed to a likely culprit: our difficulty penalty mechanism. This system, part of Alephium's original design, discourages miners from concentrating hashrate on a single chain. That's essential for a secure sharded network.
