A Blockchain Hits Undo, a Global Bank Trades Bitcoin, and AI Takes Over a Mining Site

Highlights

• Zcash cut zero-knowledge proof generation from seconds to milliseconds in testing
• Uniswap processed more than seven million swaps in a single day
• Cronos rolled back its blockchain after the $75 million Tectonic exploit
• OpenSea announced the return of Solana NFT trading after a four-year gap
• Standard Chartered launched institutional Bitcoin and Ethereum trading in the UAE
• Hyperscale Data shut down Bitcoin mining in Michigan to prepare the site for AI computing

Crypto infrastructure is being tested in very different ways. Privacy tools are getting faster, decentralized trading is processing heavier traffic, and established financial firms are bringing digital assets into familiar institutional systems. Older mining infrastructure is also finding new commercial uses.

The harder issues are operational. Better technology means little if governance breaks under stress, security failures force emergency intervention, or new products fail to attract real usage. Progress is visible, but the stories also show how much still depends on decisions made behind the scenes.

World Opens Its Identity Technology

World released ProveKit, the zero-knowledge proving toolkit used in its identity system, as open-source software. The technology allows developers to prove specific facts about a user, such as age or an identity attribute, without exposing the underlying personal information.
