## Staking & Liquid Staking

- **Staking dynamics deep-dive** : A thread by thatMediaWag analyses recent shifts — the validator pool hit an all-time high of 1,421 on June 25 before dropping to 1,339; ~19M DOT left nomination pools while total staked DOT is still up 6M net; 9 new nomination pools opened during the volatile period, suggesting sustained interest in the system (via [thatMediaWag](https://x.com/thatMediaWag/status/2079274664791322805), [2](https://x.com/thatMediaWag/status/2079274676984115593), [3](https://x.com/thatMediaWag/status/2079274714929979706), [4](https://x.com/thatMediaWag/status/2079274733242286412))
- **Bifrost migration deadline** : Last reminder for holders of vDOT/BNC on Interlay/Kintsugi to withdraw before **July 22** , and vGLMR/vMOVR holders to complete the Moonbeam migration before **July 31** (via [Bifrost](https://x.com/Bifrost/status/2079471054456779183))

## Technical Development

- **JAM & PVM instruction set** : sorpaas notes interest from JAM implementers in replacing Polkadot’s custom PVM instruction set with standard RISC-V, but the current recommendation remains to write a new instruction set due to recompiler codegen considerations (via [sorpaas](https://x.com/sorpaas/status/2079111031217922212))
- **Snow library security audit** : Trail of Bits completed an audit of the Snow library — which secures encrypted connections for Ethereum clients, Polkadot, and 80+ Rust projects — finding 10 issues and validating 8 fixes protecting against forged packets, malformed PSK indices, and oversized messages; funded by 1Password (via [trailofbits](https://x.com/trailofbits/status/2079159889054605381))
- **Midnight built on Substrate** : Cardano’s Midnight privacy chain is built on Substrate, the same SDK used across the Polkadot ecosystem, inheriting its battle-tested block production, networking, and forkless upgrade mechanisms (via [visionandvibehq](https://x.com/visionandvibehq/status/2079224108781617505))

## Governance & Transparency

- **Polkadot Cloud validator transparency** : Polkadot Cloud (TheWeb3Cloud) commits to monthly and annual transparency reports for its validator operation, covering DOT holdings, staking rewards per era, and retention and compounding percentages (via [rossbulat](https://x.com/rossbulat/status/2079181975865409546), [TheWeb3Cloud](https://x.com/TheWeb3Cloud/status/2079082626141372750))
- **Verifiable randomness funding** : Polkadot Treasury funded a drand bridge this week, enabling provably fair, verifiable randomness for Web3 gaming applications (via [cryptodailyuk](https://x.com/cryptodailyuk/status/2079271779088912580), [MelaxyGame](https://x.com/MelaxyGame/status/2079326582271799321))
