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, 2, 3, 4)
  • 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)

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)
  • 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)
  • 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)

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, TheWeb3Cloud)
  • Verifiable randomness funding: Polkadot Treasury funded a drand bridge this week, enabling provably fair, verifiable randomness for Web3 gaming applications (via cryptodailyuk, MelaxyGame)
