In Q1 of this year, we went hard with the "every rollup will be a ZK rollup" messaging. At this point, this transition seems inevitable--although it'll take some time to play out, as technology adoption always does.
This quarter, we've been seeing the rise of non-rollup use-cases for ZK that are equally exciting:
• ZK identity aka "Proof of Whale" (h/t @freakmycrypto who used it to bootstrap an anonymous X account)
• Private stablecoins, like @MyntUSD
• Verifiable exchanges aka "ZK Hyperliquid", announcements Soon TM
ZK tidal wave incoming.
