PROFILE
Ersinihsanu-affinidi
Developed and delivered full WebVH DID resolution capabilities for the affinidi/affinidi-ssi-dart repository, focusing on secure, standards-compliant handling of decentralized identifiers. Leveraged Dart for backend development and cryptography to implement HTTPS transformation, did.jsonl parsing, and deterministic historical state retrieval using versionId, versionTime, and versionNumber. Enhanced log integrity through strict validation, cryptographic verification with eddsa-jcs-2022, and witness threshold checks, while enforcing pre-rotation and deactivation protections. Improved interoperability by supporting implicit service insertion and version enforcement per the did:webvh:1.0 specification. Updated documentation and changelogs to ensure transparency, supporting robust trust and reliability in DID resolution outcomes.

Mar 1, 2026March 2026 monthly summary for affinidi/affinidi-ssi-dart focused on delivering a standards-compliant, secure WebVH DID resolution experience and solidifying the security posture around DID history logs. Key accomplishments include implementing end-to-end WebVH:1.0 DID resolution with HTTPS transformation, did.jsonl parsing, and latest-state DID Document resolution, plus support for did:webvh:1.0 version enforcement and implicit services insertion per the v1.0 spec. A robust historical resolution path was added via versionId, versionTime, and versionNumber, enabling deterministic recovery of prior DID states. Security and integrity improvements were a major driver: strict log integrity validation, cryptographic verification (eddsa-jcs-2022, assertionMethod), witness verification with thresholds, and signer authorization via updateKeys. Pre-rotation and nextKeyHashes rules were enforced, along with deactivation protections to block further updates when needed. Duplicate witness approvals were prevented, and the policy that later proofs can satisfy earlier entries was implemented to improve resilience. Changelog alignment: updated v3.6.0 CHANGELOG to reflect did:webvh resolution features and security enhancements, improving transparency for stakeholders and ecosystem interoperability. Overall impact: increases reliability, security, and interoperability for WebVH-compliant ecosystems, enabling deterministic historical state resolution and robust trust in DID resolution outcomes.
