Matter Labs unveils 'Elastic Chain,' similar to Polygon's AggLayer

ZKsync’s developer Matter Labs unveiled a new roadmap called ZKsync 3.0 this week. The team is looking to make the ecosystem more closely knit. It retrospect, it introduced a new "Elastic Chain," congruent to Polygon's AggLayer.

Via a blog post, the team contended that at the heart of ZKsync "3.0" lay the v24 upgrade that turned ZKsync from a single ZK chain into an Elastic Chain. More specifically,  

"The Elastic Chain is an infinitely extensible network of ZK chains [rollups, validiums and volitions], secured by math and seamlessly interoperable under uniform intuitive UX."

Polymarket's oracle service UMA misrules DJT-Barron verdict

Earlier this week, decentralized prediction market platform Polymarket opposed its decentralized oracle service UMA’s verdict with respect to a market bet on whether Donald Trump’s son Barron Trump was involved with the DJT token or not.

Polymarket claimed that Barron Trump was involved with the DJT token "in some way.” As a result, it announced that it would refund holders of "yes" contracts. According to the team,

"It is conclusive that he was, in fact, involved in some way... As such, it is crucial that markets resolve to the truth by the best means possible, even if it is not a popular decision."

Typically, whenever the outcome of a prediction market is contradicted, decentralized oracle UMA is brought in to resolve it. UMA token holders vote on the outcome. In this case, most voters voted no. After this incident, the Polymarket team is also looking to improve its oracle and resolution methodology.

Bitcoin Virtual Machine team launches ZK proof service BitZK

BitZK - a zero-knowledge proof service that bolsters Bitcoin's scalability by allowing users to create rollups and migrate apps from Ethereum to Bitcoin - was recently put to sea by Bitcoin Virtual Machine [BVM] developers.

The BVM blockchains on Bitcoin are said to be the maiden instance of Bitcoin ZK-rollups on the mainnet. This, according to the developers, is a revolutionary quantum leap.  

BVM is charging a minimum of $99 in return for monthly access to its BitZK service. It already has a queued list of early users including Octopus Bridge and POWD3R Blockchain.
