How decentralized identifiers eliminate credential databases and single points of failure.

How btcr2 uses MuSig2 n-of-n Schnorr multi-signatures and Nostr relays for decentralized beacon aggregation.

How the 256-bit SMT beacon batches DID updates so on-chain observers learn nothing, and the aggregator can't tell which participants actually updated or what their updates contain.

Techniques for proving claims about yourself without revealing underlying data.

How sidecar delivery and closed-loop resolution enable pairwise, non-correlatable DIDs.

Practical steps for resolving Bitcoin-anchored DIDs in your applications.

How a W3C Data Integrity cryptosuite was built using Bitcoin-native Schnorr signatures over secp256k1.

Deep dive into the three-tier beacon architecture (Singleton, CAS, SMT) and how aggregation amortizes on-chain costs.

A technical walkthrough of ION's Sidetree-on-Bitcoin design, and an honest accounting of its current status now that Microsoft has pivoted to did:web.

How Taproot activation, Schnorr signatures, and Bech32m encoding directly shaped btcr2's design decisions.

How btcr2 identifiers are derived offline from secp256k1 keys or genesis documents, and why this changes the economics of decentralized identity.

What btcr2 is, why a v2 was needed, and how it improves on the original BTCR with zero-cost creation, stable identifiers, and private resolution.

Comparing SSI with OAuth/SAML and why the shift matters for data ownership.

An overview of the DID spec landscape, Bitcoin-native DID methods, and the road ahead.

Examining the tradeoffs of anchoring DIDs to Bitcoin and how they compare to other approaches.
