BlockSign - The Digital Asset Operation Platform

Building digital trust without being ISO 27001 certified is just a well-formatted promise. At BlockSign GmbH, we don't ask for trust, we get audited for it. ISO 27001 certified for a year now and just past our annual surveillance audit 🚀 Digital trust shouldn't a vibe. It should be audited year after year. A big shout out to our trust partners: @Swisscom Trust Services & @nbxcom. Please find more info regarding our ISO certification here:

Wallets are as essential as browsers. They are the operational gateway through which digital assets are accessed, managed, secured, and governed. At BlockSign, we approached wallet infrastructure from the perspective of a trust-layer provider. We began with a 100% non-custodial architecture and developed the platform around the requirements of professional DeFi users, organisations, and teams. This meant going far beyond the basic storage of private keys. Professional digital asset operations require role-based permissions, policy-driven approvals, transaction limits, clear responsibilities, audit trails, and verifiable execution. Only after completing the self-custody model did we address the next challenge: How can the same modern operational structure fully meet the requirements of MiCA while preserving security, usability, and operational flexibility? The answer is a carefully integrated ecosystem of specialised partners. Through our strategic partner @nbxcom authorised as a Crypto-Asset Service Provider under MiCA, BlockSign can provide a regulated custody and crypto-asset services model across the European Economic Area. NBX is also approved as a recognised custodian of crypto-assets for exchange-listed products on SIX Swiss Exchange, demonstrating that its custody infrastructure meets the standards required for institutional capital-market products. Through NBX, Notabene provides the Travel Rule infrastructure, while Chainalysis supports transaction monitoring, wallet screening, and AML risk management. Together, BlockSign and its partner provide the custody, compliance, governance, security, and operational controls required for MiCA-compliant digital asset operations. Organisations can therefore choose between three models: 100% self-custody, regulated MiCA-compliant custody via NBX, or self-custody with an additional disaster-recovery layer. All three models are integrated into one policy-driven platform designed for professional digital asset operations. Because institutional wallet infrastructure is not only about holding assets. It is about control, accountability, compliance, security, and verifiable execution.

Compliance als Wettbewerbsvorteil - Teil 3/3: Dieser Teil erklärt, warum Unternehmen nicht nur Wallets brauchen, sondern Rollen, Regeln, Freigaben, Nachweise, Audit Logs, eSignaturen und Reporting rund um jede Digital-Asset-Bewegung. Ein wichtiger Punkt ist, dass die drei Nutzergruppen nicht strikt voneinander getrennt sind. Die Grenzen verschwimmen. Nutzer können wachsen, Anforderungen können sich ändern, und ein Wallet-Setup, das am Anfang ausreichend war, kann später zu einfach oder regulatorisch unpassend werden.

Im Mittelpunkt steht die Frage: Wie lassen sich Kontrolle, Sicherheit und Compliance sinnvoll miteinander verbinden, ohne die operative Handlungsfähigkeit zu verlieren? Der vollständige Artikel: linkedin.com/pulse/teil-23-…

Vom Einzelwallet zur professionellen Team-Treasury - Teil 2/3 Sobald mehrere Personen digitale Assets verwalten, reichen Seed Phrase und einzelner Wallet-Zugang nicht mehr aus. Unternehmen, DAOs und institutionelle Nutzer benötigen klare Rollen, Freigabeprozesse, Limits, Policies und nachvollziehbare Audit Trails. In Teil 2 unserer Serie zeigen wir, welches Wallet- und Governance-Setup zu welchem Anwendungsfall passt – vom Einzelanwender bis zur regulierten Organisation.

To all the people looking to fork the Yoroi wallet, beware: 🚨 ⚠️ Mantaining a wallet is not that simple. It's not a profitable business, requires a lot of maintenance, and nothing can prepare you for the toll on your mental health that comes with the customer support needs.

Start der Serie: Dies ist der erste Teil einer dreiteiligen Serie über BlockSign Digital Asset Operations. Teil 1 erklärt die Grundmodelle. Teil 2 zeigt, welche Nutzergruppen davon profitieren. Teil 3 beschreibt, warum BlockSign mehr ist als ein Wallet: eine Operations-Schicht mit Governance, eSignaturen, Evidence, Reporting und Blockchain-Verankerung. linkedin.com/pulse/teil-13-…

Ein Wallet speichert Keys. Eine Operations-Schicht steuert Verantwortung. Wer digitale Assets professionell verwalten will, muss zuerst klären: Wer hält den Schlüssel? In Teil 1 unserer 3-teiligen Serie zu BlockSign Digital Asset Operations erklären wir drei Modelle: I. Self-Custody II. Full Custody via NBX III. Disaster Recovery Denn für Unternehmen, DAOs, Treasuries und regulierte Institutionen reicht ein Wallet allein nicht aus. Digitale Assets brauchen Rollen, Freigaben, Policies, Audit Trails, Reporting und klare Verantwortlichkeiten. Genau hier setzt BlockSign an. Teil 1: Wer hält den Schlüssel? ⬇️ #BlockSign #DigitalAssets #Custody #SelfCustody #MiCA #Cardano

@adatainment Let’s have a look. Task is clear!

Creating a DRep from a hardware wallet is great for peace of mind, until voting season: Every action signed individually, no bulk voting, endless clicking. Is anyone solving this, or is it just the price for key security?

NO BOTS. NO AGENTS. VERIFIED HUMANS ONLY. How can organizations make sure that only real, verified humans enter a confidential video call? CallShield adds a Proof-of-Human trust layer in front of video meetings. Before the real meeting link is revealed, invited participants must complete the required verification, from fast liveness checks to stronger identity verification flows. This is especially relevant for government-related meetings, financial services, digital asset operations, legal and compliance workflows, executive calls and high-security institutional communication.

The hottest topic: Stablecoin Open USD 1. What is Open USD? Open USD, ticker OUSD, is a new U.S.-dollar stablecoin initiative by Open Standard. It was announced on June 30, 2026 and is expected to go live later in 2026. Open Standard describes it as a stablecoin for global money movement, built around three ideas: no mint/redeem fees for businesses, shared reserve economics, and collaborative governance through an independent company backed by partners. The important point: Open USD is not just another stablecoin. It is a distribution coalition. The official partner list includes payment networks, banks, fintechs, exchanges, wallets, infrastructure providers and blockchain ecosystems, including Visa, Stripe, Mastercard, American Express, BlackRock, BNY, Standard Chartered, Google, Shopify, Coinbase, Fireblocks, MetaMask, Solana, Base, Stellar, Polygon, Aptos Labs, Plasma and Tempo. 2. Is it good for users? Potentially yes, but not automatically: For users, the positive development is more competition. If Open USD really creates cheaper, more open stablecoin infrastructure, users could benefit from better availability, faster payments, more wallet/exchange support and potentially lower costs. Reuters reports that Open USD is designed to let businesses mint and redeem without cost or volume limits, while reserve earnings are shared with partners after a management fee. But the user benefit depends on whether companies actually pass those advantages through. A stablecoin can be cheaper at the infrastructure level while the end user still pays fees through wallets, exchanges, payment apps or merchants. 3. Biggest pros The biggest pro is distribution. Open USD has a very strong partner network from day one. Stablecoins win not only through technology, but through where they are accepted, who integrates them, and whether merchants, banks, wallets and payment processors actually use them. The second pro is competition with USDT and USDC. Fortune describes Open USD as a serious challenge to Tether and Circle, and reports that Tether and Circle are not part of the consortium. That matters because the stablecoin market has been highly concentrated around those two issuers. The third pro is governance and shared economics. Open Standard positions Open USD as a stablecoin where governance and economics are shared with the businesses growing adoption, rather than controlled by one dominant issuer. That could be attractive to large institutions that do not want to depend entirely on Circle or Tether. 4. Biggest contras The biggest risk is that the launch details are still incomplete. Open USD is announced, but not live. Fortune reported that Open Standard had not disclosed which blockchain the stablecoin will operate on. The official partner list includes several chain ecosystems, but a partner listing is not the same as a confirmed technical deployment. The third risk is centralization by another name. Open USD may be more open than a single-issuer model, but it is still a consortium of very large financial and technology companies. That can be good for adoption, but it does not automatically mean neutral public infrastructure. This is a real positive fact: Cardano’s native-asset model is technically elegant for stablecoins. Cardano’s developer documentation explains that native tokens are tracked directly by the ledger, without a smart contract for basic transfers, reducing contract-execution risk for simple token movement. 5. How could BlockSign add Open USD? Open USD creates more stablecoin competition. More competition creates more need for trust infrastructure. That is BlockSign’s field. Our conclusion: Open USD is a positive market signal because it increases stablecoin competition and moves the discussion from “who issued the biggest coin?” to “who controls distribution, trust, governance and real-world usage?”

@GeroWallet Well done! Thank you.

Amidst the gathering shadows, a new light is forged for those whose watchfires cannot go dark. Introducing Nexus, a singular key to the multi-chain realms. Forged first for Cardano, Nexus grants its bearer sight over market data, token wealth, prices, swaps across eleven markets, digital relic values, and hidden fortunes within every vault. We speak with reverence of @TapTools. For four long years, they stood as the great palantír through which a million degens gazed upon the markets. But as their watch draws to a close, those who relied on their sight must not wander in darkness. Nexus stands ready as the new stronghold for those who seek the truth of the realm’s data. And within it, a greater power awakens: live, decoded dApp event streams. Where Cardano chroniclers once relied on webhooks, standing up an endpoint, verifying signatures, and handling retries, Nexus changes the path. Open a WebSocket, subscribe to a topic, and receive decoded contract events in mere heartbeats: UTxO phase, owner, datum, amounts, all at sub-block latency. No webhook server. No indexer. #Cardano today. #Bitcoin and #Midnight on the roadmap. Public launch is near. Claim early access here: nexus.gerowallet.io

Wir gratulieren unserem Partner @nbxcom herzlich zu diesem wichtigen Meilenstein: der Zulassung als Crypto-Asset Service Provider unter MiCA. Ein großer Erfolg und ein starkes Signal für regulierte, europäische Krypto-Infrastruktur.

The hard part of tokenization is not creating a token. The hard part is making a real-world asset institutionally usable. A token can represent value, rights, claims or access. But by itself, it does not answer the questions that matter in regulated markets: - Who verified the investor? - Which legal structure defines the asset? - Who is allowed to approve transactions? - How are custody, reporting and settlement controlled? - Where is the audit trail? - Can every relevant action be proven? This is why the next phase of tokenization will not be won by technology narratives alone. It will be won by infrastructure. At BlockSign, we are building this missing trust layer: proof of human, signatures, governance, custody coordination, compliance workflows and blockchain-based proof combined into one operational framework. Because institutions do not adopt tokens. They adopt reliable systems. #Tokenization #RWA #DigitalAssets #TrustLayer

PRE-CALL PROOF OF HUMAN Our product test for Pre-Call Proof of Human will be completed soon. We believe this is one of the most urgently needed security features in digital communication today. As AI-driven impersonation, voice cloning, and video deepfakes become more realistic, companies can no longer rely on appearance or voice alone as proof of identity. The question is no longer only: “Can we detect a deepfake during a call?”. The better question is: “Can we verify before the call whether the participants are actually human?” BlockSign Verify can be placed in front of common video-call systems such as Microsoft Teams, Google Meet, Zoom and similar platforms. The inviting party can send a normal invitation link. Before entering the actual call, participants are asked to complete a short Proof-of-Human check that takes a maximum of around eight seconds (NO DATA WILL BE STORED!) We are convinced that the future of telecommunications will include verification technologies like this running quietly in the background, protecting meetings, onboarding processes, approvals, and sensitive business interactions before they even begin.

How do institutions judge GDPR? GDPR compliance is not proven by security architecture alone. Encryption and distributed storage infrastructure can be relevant technical measures under Article 32 GDPR. However, GDPR compliance also requires demonstrable accountability, clearly defined controller and processor responsibilities, documented processing activities, sub-processor governance, breach notification procedures, and evidence that these processes operate effectively in practice. Institutions ask different questions: Who is the controller? Who is the processor? Who manages sub-processors? Who maintains records of processing? Who verifies deletion under Article 17? Who handles data subject requests? Who reports a suspected breach, and who can prove that the process was followed? This is the key difference between a security claim and institutional GDPR readiness. BlockSign takes the stronger position by combining privacy-conscious architecture with clear governance: a German legal entity, European infrastructure principles, documented enterprise workflows, controlled access, audit trails, eIDAS-aligned signature evidence, and an ISO 27001-certified information security management system. In regulated markets, the question is not only: “The provider cannot read your data.” The real question is: “Who is responsible if something goes wrong, and can you prove compliance?” That is how institutions judge GDPR. This is why BlockSign does not rely on technical architecture alone. Our GDPR and information security approach is supported by an externally audited ISO/IEC 27001-certified #ISMS and led by Patrick Rayermann, an experienced CISO, certified IT Security Officer, certified Data Protection Officer, and former Managing Director of a German compliance and data protection company. For institutional customers, this matters: GDPR readiness requires not only secure technology, but responsible governance, documented processes, and people who know how to operate them. BlockSign delivers a unique Cardano-based trust infrastructure for multichain environments, combining digital identity, e-signatures, auditability, and compliance-grade workflows aligned with #MiCA, European #GDPR requirements, and an externally audited ISO/IEC 27001:2022-certified information security management system.
