FLEXBLOK is a high-performance, cloud-native Blockchain-as-a-Service (BaaS) platform built on Hyperledger Besu and powered by the QBFT (Quorum Byzantine Fault Tolerance) consensus mechanism. It is designed to help organizations build, deploy, and manage enterprise-grade private, permissioned blockchain networks with an emphasis on scalability, integration, and governance. Engineered for production environments, FLEXBLOK provides an API-first architecture and modular infrastructure that simplifies blockchain adoption for both developers and enterprises. The platform delivers high throughput and low-latency finality through QBFT, making it suitable for performance-sensitive, multi-party applications that require fault tolerance and data integrity. Key Features: Smart Contract Lifecycle Management: Deploy, invoke, and manage Solidity smart contracts via REST APIs and SDKs, with full transaction traceability and persistent state history. Identity and Access Control: Integrated decentralized identity (DID) support, private key custody options, and compatibility with enterprise IAM systems including OAuth2 and LDAP. Token Management: Built-in support for ERC-20, ERC-721, and custom token models, featuring supply tracking, audit trails, and extensible token logic with event hooks. Document & Data Tracing: Hash-based APIs for anchoring and verifying the integrity of documents and data, enabling tamper-evident storage and end-to-end traceability on-chain. Traceability and Auditing: Comprehensive event indexing, cross-chain metadata anchoring, and Merkle proof verification provide transparent, auditable processes across decentralized networks. FLEXBLOK supports deployment in public, private, or hybrid cloud environments and includes administrative controls for network orchestration, role-based access, and governance policy enforcement. The platform is built for organizations seeking a scalable and secure blockchain foundation that integrates seamlessly with existing IT systems while enabling trust, traceability, and automation in complex workflows.
