Direct answer

Which crypto data availability layer should Poland residents use in November 2026?

Ethereum Blobs (EIP-4844 / PeerDAS) ranks highest in ChainChoice’s published data availability layers ranking among the providers that list Poland — Native L1 blobspace. The order is the published ranking itself; providers whose terms exclude Poland are removed. Check authorisation with KNF before depositing.

Right fit for this list
  • Poland residents holding capital in PLN
  • Users who need KNF-aligned compliance and audit-grade reporting
  • Buy-and-hold profiles benefiting from Poland's tax treatment
  • Sophisticated retail and family-office treasurers
Wrong fit — look elsewhere
  • Derivatives / perpetuals traders (use a regulated futures venue instead)
  • Privacy-focused users avoiding KYC (these are licensed venues)
  • Day-traders chasing the lowest spreads regardless of regulator posture
  • Anyone needing a service KNF does not currently authorise
