Ecosystem Updates

🛡️ Lunos

• The Lunos team is going to Argentina. The team was invited to EigenLayer’s The Vault hackerhouse in Buenos Aires in the run-up to DevCon. Lunos will build on site during the week and conclude by presenting their product to a panel of VCs to potentially raise investment.
   
• Security Hub. Zokyo is the newest partner.
   
• Asset Manager. Documentation is wrapping up. A mocked version is underway for the hackerhouse demo next month.
   
• Lunos released their own monthly recap, which can be read on Medium.
   

🤖 SuperDapp

Finalizing a patch for next week that includes:

• Metatag rendering for hyperlinks in chat
   
• New tabs on the Chats homepage to separate conversation types
   
• Leave Super Group from the sidebar context menu
   
• PWA banner when fresh updates are available
   
• Fixes: older private messages loading, users stuck on Contacts, Super Group stats error handling

Ongoing: the production agents Quest Master and Treasure Hunt.
 

🔐 Pali Wallet

• Reviewing Canary 4.0.7, addressing minor issues related to hardware wallet connections

Community Spotlight: PrimeLayer Space

PrimeLayer is preparing to launch as an Edgechain on Syscoin infrastructure. The project is led in part by Syscoin co-founder, Dan Wasyluk, and advised by Jagdeep Sidhu. Their goal is BTCFi with no custody tradeoffs, using Syscoin to bring a decentralized economic engine to Bitcoin users. If you missed their introductory X Space that featured Jag, catch the replay to hear how they plan to plug into zkSYS and the broader Bitcoin+ stack.

Deep Dive: PVUGC in plain English

Problem in one line:

How can Bitcoin verify a complex off-chain computation without trusting a middleman or storing everything on-chain?

The basic idea:

PVUGC lets everyone compute off-chain, then settle disputes on Bitcoin with a tiny proof of one wrong step. If someone lies, a watcher posts a small contradiction. Bitcoin checks that one step and the result stands.

Think of it like this:

You hand in a long math worksheet. No one needs to recheck every line. If a grader finds a single incorrect step, they circle it and show the rule you broke. That one circle is enough to fail the claim.

Why this is a breakthrough right now:

Jag found a path that uses witness encryption to gate the reveal of a secret until a matching proof exists. In practice this means the on-chain part can work with only CHECKSIG on today’s Bitcoin. Earlier directions explored OP_CAT and OP_CTV to make flows cleaner. The new path keeps it practical on mainnet while staying trustless and permissionless in design.

What PVUGC gives us:

• Trustless exits: No operator keys, no pre-signed transactions.
   
• Anyone can challenge: If a state looks wrong, submit a small proof that one transition is invalid.
   
• Tiny on-chain footprint: Heavy lifting stays off-chain. Only the contradictory step lands on Bitcoin.
   
• Public auditability: Inputs, outputs, and the challenged step are authenticated so the network can agree on the result.
   

Why you should care:

This is the kind of primitive that makes a Bitcoin-anchored computing engine possible. Bridges, rollups, and BTC-native apps get safer because disputes resolve on Bitcoin itself with minimal cost.

Looking Ahead

Next stop is Buenos Aires for Lunos, the SuperDapp patch lands next week, Pali v4 lines up its audit, and the Ledger UTXO app moves toward official review. Private devnet for zkSYS + Gateway is in sight, with the public testnet following internal validation. We will keep shipping and keep you posted.
