The crypto sector has seen no shortage of headlines this week — from fresh privacy infrastructure launches to multi-million dollar institutional products, and even an unexpected network outage on one of the industry’s most-used blockchains.
Scroll Introduces ‘Cloak’ for Institutional Privacy
Layer-2 (L2) network Scroll has unveiled Cloak, a privacy system built to give institutions more control over confidential blockchain transactions. Powered by zero-knowledge proofs, the system keeps sensitive transaction details hidden from the public while still allowing for regulatory audits.

Transactions flow through a permissioned sequencer that verifies them without exposing critical data, ensuring only the sender and sequencer have visibility. The early version is live on Scroll’s testnet, with a full mainnet launch expected soon. Despite the announcement, Scroll’s SCR token has slipped nearly 10% in 24 hours.

Polygon Faces Brief Disruption After Upgrade
Polygon’s network experienced a one-hour halt in block production following its Heimdall upgrade. The incident was triggered when a validator exited the mainnet, exposing a consensus bug. While the core Bor layer continued processing transactions, front-end and RPC services saw temporary downtime. The team has since restored operations, and the POL token has rebounded after an initial dip.
