> Educational articles on privacy-preserving identity: Know Your Agent (KYA), reusable KYC, zero-knowledge credentials and how MintID compares to other identity chains. Blog # Notes from the engineering team Plain-language explainers on the problems MintID works on: verifying the humans behind AI agents, reusing KYC without re-sharing documents, and proving claims in zero knowledge. 2026-08-22 7 min read ## [How we grade identity — and how we keep it fresh](/en/blog/grades-follow-eidas) design note What each MintID assurance grade A1–A4 certifies, mapped onto eIDAS, ISO/IEC 29115, ETSI TS 119 461, NIST IAL and the EU anti-money-laundering regimes — and why freshness is a second axis (bands F1–F4) rather than a decaying grade, with re-verification periods taken from the standards. 2026-08-02 11 min read ## [The first live network: running, not written](/en/blog/first-live-network) milestone MintID stood up its first live network — a single-validator chain and the verifier service, deployed behind TLS from a reproducible bring-up package — and drove the first end-to-end test through it: proof-backed reads, live ten-second challenges, a fixed-slot decision record and a complete MCP session. Protocol-code defects found: zero. Alongside it, what the v2.0 re-freeze leaves fixed in the tokenomics — the hard cap, the ratified bands, the price-independent launch gate, the protocol cuts and the post-emission plan — now reads as closed policy, not promise. 2026-08-02 9 min read ## [We audited ourselves before anyone asked](/en/blog/we-audited-ourselves) transparency Crypto projects publish code audits after the token is sold. MintID put itself through a full economic-viability audit — solvency of every actor, survivability of the project — before genesis, against its own frozen corpus, with the authorship on the cover: [Conectia PRO](https://conectia.pro/en/), a related-party service provider to the protocol. The answer came within days: a full re-freeze of the corpus as v2.0. The verdict, stated whole: a qualified opinion, a demand thesis corroborated against independent sources, and five critical findings with five written answers. The report is downloadable, unedited. 2026-07-26 6 min read ## [Verification is now a tool call](/en/blog/verification-is-a-tool-call) announcement The MintID client family grew a third member — not another language, a protocol. An MCP server exposes the three frozen verifier-service operations as tools any agent framework can call, with the same closed reason-code vocabulary: a rejection stays a decision, now readable by an agent. 2026-07-26 8 min read ## [The graduated-knowledge slot: an identity profile for x402 and Web Bot Auth](/en/blog/x402-web-bot-auth-identity-profile) standards Between an anonymous payment and a doxxed buyer sits the slot only a zero-knowledge proof can fill: human-backed, in scope, unrevoked — and unrevealed. MintID has drafted the standards-track transport profile that fits it, with machine-readable schemas and a validation suite. 2026-07-26 7 min read ## [AI writes the evidence. It doesn’t get to decide.](/en/blog/ai-writes-the-evidence) issuance AI screeners are collapsing the cost of KYC — which is good for a credential rail. But a screener produces evidence, not verdicts. The MintID issuer plane now enforces that division by construction: enumerated checks with provenance, or a named rejection — and no field anywhere that could carry a provider-asserted grade. 2026-07-26 7 min read ## [The pay-per-use web is here. It needs Know Your Agent.](/en/blog/x402-pay-per-use-web-needs-identity) agentic identity Cloudflare’s Monetization Gateway makes agents pay per call over x402. Payment and fleet signatures are solved — the accountable human behind the long tail of agents is not. Why zero-knowledge KYA is the missing half of the agentic web. 2026-07-20 6 min read ## [Implementing clients: where the rubber meets the road](/en/blog/implementing-clients) architecture The multi-language strategy behind the MintID SDKs is decided and locked into the spec: one audited verification core, embedded in Python — and TypeScript and PHP clients that carry no cryptography and no policy, built against a verification service you host yourself. Why thin clients are the strongest guarantee we could ship. 2026-07-20 5 min read ## [The MintID SDKs are in development: TypeScript, PHP and Python](/en/blog/embedded-not-hosted) announcement Development of the MintID verifier SDKs has started — TypeScript, PHP and Python — and we expect the first builds tested and working in a couple of weeks. Inside every binding, the same non-negotiables: nine acceptance checks, a ten-second proof lifetime and zero policy knobs. 2026-07-13 9 min read ## [MintID vs ERC-8004: trustless agents still need accountable humans](/en/blog/mintid-vs-erc-8004) comparison ERC-8004 makes agents discoverable and their work verifiable — but its identity is a transferable NFT, its reputation is Sybil-prone, and recourse is out of scope. Where the standard stops, and how human-backed credentials fill the gap. 2026-07-10 7 min read ## [Scope an agent can prove, axis by axis](/en/blog/agent-scope-axis-by-axis) agent credentials Agent authorisation today is a plaintext scope inside a token: all or nothing. A scope structured along five provable axes applies selective disclosure to authorisation itself — the merchant learns the limit, not the mandate. 2026-06-25 7 min read ## [One KYC, every agent: the economics of amortised accountability](/en/blog/amortised-accountability) economics Per-check verification re-pays KYC at every counterparty. Amortisation — one human verification backing N agent credentials — changes the cost structure of trust. The five flows a sovereign identity rail earns from. 2026-06-11 8 min read ## [Identification, not surveillance](/en/blog/identification-not-surveillance) privacy Identifying an agent once, paid and consented, is categorically different from holding a handle that tracks its human forever. How pay-per-disclosure, pseudonym churn and on-chain receipts make surveillance structurally impossible. 2026-05-27 9 min read ## [Money before identity: how disputes settle without ever learning who](/en/blog/money-before-identity) disputes Most disputes want money back, not a name. How a dispute rail built on self-custodied escrow, anonymous arbitration and due process settles claims without unmasking anyone — and why that protects both sides. 2026-05-14 10 min read ## [The agentic identity problem: no human at the keyboard](/en/blog/agentic-identity-problem) agentic identity Every identity system of the last twenty years assumed a human at the keyboard. AI agents break that assumption — and six concrete failures follow. Why the accountability-versus-privacy binary is the one to solve first. 2026-04-13 8 min read ## [Reusable KYC explained](/en/blog/reusable-kyc-explained) reusable kyc Reusable KYC explained: verify once with an approved issuer, then prove age, assurance grade or status anywhere in zero knowledge — with no PII on-chain. 2026-03-30 8 min read ## [MintID vs Concordium](/en/blog/mintid-vs-concordium) comparison How MintID and Concordium differ: identity architecture, anonymity revocation vs zero-knowledge presentations, compliance models and token design. 2026-03-01 9 min read ## [What is Know Your Agent (KYA)?](/en/blog/what-is-know-your-agent) kya What Know Your Agent (KYA) means, why AI agents need verified human backing, how KYA differs from KYC, and how zero-knowledge agent credentials work. --- Source: https://mintid.net/en/blog · Blog — identity, KYA and reusable KYC explained — MintID
