We are getting exceptional results optimizing our SHPINCS+(-) in our zkVM (Airbender based) for PQ smart accounts. I think we just removed one of the biggest excuses against post-quantum smart accounts: cost.
Full SLH-DSA verification on @syscoin zkSYS now runs in ~1.36–1.37M effective cycles—only ~2.9× ECDSA recover.
Portable code. No custom circuit. Upstream zkSync/Airbender. Live on testnet. This will be our last major change before entering mainnet. 🧵
Next up is Liberty mainnet activation, expected around Monday, 17 August.
After activation, we will continue sharing updates on Pali, zkSYS, the proposed $zkSYS model and new Sentry Node use cases.
Liberty is out. Bridge V2 is ready for mainnet. Governance voting is open. The Sentry Node Competition has a winner.
Here is what moved forward across Syscoin this week:
The Sentry Node Competition has officially wrapped up.
Congratulations to sys1qafdwz0qae4mgekxkj58tj4ea6kq6d5uh2rc5pn and thank you to everyone who deployed a node and took part.

Reminder to Sentry Node operators: voting is now open.
The Ecosystem Sustainability & Liability Reduction Proposal covers ongoing infrastructure and ecosystem costs, the next funding period, and a plan to begin reducing existing liabilities.
Please read the proposal and cast your vote.

Quantum computers could eventually break the digital signatures most blockchains use today. Syscoin is already designing around that risk.
Think of every Sentry Node having its own quantum-safe digital stamp. Before the network accepts something, it would collect 801 stamps from several independent groups of nodes.
That full proof is only about 3.6MB, roughly the size of a photo, and can be checked in parallel in around 1 millisecond.
Syscoin’s 2.5-minute blocks, Bitcoin merge-mining and finality every five blocks give the network enough room to handle these larger, safer proofs. The same hash-based technology can also support the data layer behind zkSYS.
In simple terms: thousands of independent nodes can prove they agree without relying on one shared key, while staying secure against future quantum computers.
Most blockchains may need to bolt this on later. Syscoin is designing for it now.
Working on SLH DSA based sentry nodes. Removing the DKG and MPC replacing it with direct signatures, and a 3.6mb commitment of 801 signatures which validate in 1ms (parallel). A global key will replace the BLS owner key with a FIPS 205 SLH-DSA-128s (7856 bytes). At around 3k SNs this is less than 24mb. A merklized tree of subkeys are created under C11 (SPHINCS-) which is 3976 bytes and 2^14 signature budget. Much faster to sign, and gives the 3.6mb commitment with 801sigs. Why 801? Because you have 4 quorums of 400 nodes, while each quorum you want 267/400 safety (33% liveness), distributed over 4 quorums and 3 out of 4 need to sign. 267*3=801. This will only work on @syscoin because it is purposefully slow at 2.5m block times, auxpow with @bitcoin and we finalize every 5 blocks. This gives adequate buffer for the bandwidth overhead. The DA layer is also hash based (keccak or blake2s), which feeds zkSYS (zkVM layer) for speed and convenience. Lastly once we figure out which direction BTC is going (likely shrimp/shrinc/sphincs), we can complete utxo PQ, once EOAs on eth figure out which way (hopefully hash based), we will finish EVM PQ. The reason we need the safe large sigs is because we reuse addresses with sentry nodes across validator usages, and although hash based snarks are becoming viable, they still open new games and attacks and I prefer safety first with 128+ bit PQ security at minimum.
The Sentry Node Competition has a winner.

Syscoin's next mainnet upgrade is ready.
Liberty v5.1.0 ships Bridge V2, hardened ChainLocks, coordinated Core + NEVM changes and new Bitcoin infrastructure.
Activation is expected around Monday, 17 August.
Node Operators: upgrade now.

📢 PSA Reminder: @binance withdrawals for $SYS close on July 27.
Move your $SYS to a wallet you control before the deadline. Pali Wallet is a browser extension wallet built for secure self-custody.

The Sentry Node competition is nearly over.
Set up a qualifying node and keep it online through the campaign window for your chance to win 100,000 $SYS. One operator wins for every 100 new nodes added.
Ends July 27, 3:00 AM UTC.

It seems @the_matter_labs has removed operational Gateway settlement support from the upstream @zksync OS server and rescoped release v31.0 away from public Gateway-routed interop. Their stated near-term priority is private institutional environments, direct Ethereum settlement and private atomic interop.
@syscoin intends to preserve the original Gateway and public interoperability architecture: hierarchically scaled chains anchored to a decentralized base layer, with the network economy aligned around that base. This now creates an alternative for the ZKsync community and $ZK holders who still believe in the public Elastic Network vision.
I wrote about this architecture in 2021 and still believe it offers the strongest decentralized path for interoperable chains and scaling through aggregation.
The solution focuses on gateway based interop scaling with blake2s hash based DA secured through Bitcoin merge-mining. We are keeping that vision going and the existing community who want to see the technology through is most welcome to join the initiative.
