SHRINCS & SHRIMPS are post-quantum signature schemes designed for Bitcoin with:
- 324 B SHRINCS stateful signature (q=0)
- 4052 B SHRINCS stateless signature
- 2564 B SHRIMPS compact signature
- 4052 B SHRIMPS fallback signature
I've been experimenting with SHRIMPS lately and just published the hashsig repo on Github.
Hashsig is a paper-faithful Go/Cpp implementation of the crypto primitives from Mikhail and @n1ckler, Hash-based Signature Schemes for Bitcoin.
Aka SHRIMPS.

This repo is research grade only and I expect to iterate over further proposals. There's still plenty of work and research to do!
Community feedback is more than welcome.
@n1ckler@Blockstream@blksresearch@OPNEXT2026 Thanks, means a lot! I’m going to create a “hashsig” repo with crypto primitives only + test vectors and tag it as unaudited / research-grade.
Would welcome a look from you or Mikhail once it’s in shape.
I implemented @Blockstream ‘s SHRINCS/SHRIMPS PQ proposal on a practical Bitcoin-like chain I’ve build and… it works beautifully.
- 324-byte stateful signature
- 2548-byte stateless signature
- 2- leaf P2MR addresses
Kudos Kudinov & Nick
In 2010, Gavin Andresen created the Bitcoin Faucet and gave away 5 BTC to anyone who visited. Most people ignored it.
Today, we're giving away 5 Laxes per visitor at https://t.co/gL4PQIyxia.
We even use proof-of-work to prevent automated spam, a nod to Hashcash by @adam3us.
Don't make the same mistake twice.
Parallax 2025 Recap
2025 was about proving that Parallax can exist, run, and evolve under real-world conditions.
Launched on October 28 2025.
Since then:
• 1.5 TH/s peak network hashrate (GPU only)
• 1,000+ peak unique miners
• 100+ nodes online at peak
• 35,980 total transactions
• 2,793 total addresses
• Listed on 7 mining pools (@coolpooltop@K1Pool GTPool RPlant LuckyPool)
• Listed on 5 exchanges (@safetrade@nonkyc_exchange @exbitron @BITGoGet Rabid-Rabbit)
• Listed on CoinGecko
• 30,000+ unique website visits
On the protocol side:
• Migrated difficulty adjustment from DAA to ASERT based on community feedback
• Deployed several client optimizations and stability improvements
On the philosophical side:
• Published the Parallax Doctrine, a set of axioms and constraints defining what Parallax is and what it refuses to become
No premine.
No VC.
No shortcuts.
Just a Proof-of-Work network finding its footing in adversarial reality.
Thank you to everyone who mined, ran nodes, reviewed code, challenged assumptions, and stayed honest.
2026 continues.
Exciting to see the first token on the Parallax block chain @prlxchain .
