Features

• Private Ledger Infrastructure - Provides a private, permissioned distributed ledger infrastructure for recording and managing business transactions.
• State Evolution Validation - Validates the logic that all network participants must satisfy to evolve shared ledger states.
• Notary Uniqueness Validation - Uses specialized notary clusters to verify transaction uniqueness and prevent double-spending.
• Digital Asset Management - Provides a system for issuing and managing the lifecycle of custom tokens and financial instruments on the ledger.
• Distributed Application Deployments - Manages the distribution of custom business logic and data schemas across a network of shared ledger nodes.
• Private Peer-to-Peer Networks - Implements a peer-to-peer system for creating shared records of facts between specific participants without global broadcasting.
• Distributed Process Coordination - Manages distributed business processes as stateful sequences of messages and signatures between network participants.
• Decentralized & Blockchain Technologies - Offers a comprehensive platform for building private, interoperable business networks with smart contracts and strict privacy.
• UTXO Models - Tracks the evolution of state through a chain of unspent transaction outputs rather than global balances.
• Global Network Directories - Implements directory services that provide network maps for node discovery and participant communication.
• Peer-to-Peer Networking - Enables independent nodes to exchange data and transactions directly without a central authority.
• Privacy-Preserving State Distribution - Maintains strict privacy by distributing ledger state only to the participants involved in a transaction.
• Business Network Construction - Enables the creation of private business networks for conducting direct transactions and executing smart contracts.
• Transactional Message Coordination - Coordinates the delivery of messages and negotiation sequences to ensure atomicity in multi-step transactions.
• Smart Contract Execution Environments - Executes business logic written in Java or Kotlin within a JVM runtime to automate ledger agreements.
• JVM Runtimes - Executes smart contract business logic written in Java or Kotlin within a JVM runtime.
• Business Network Governance - Provides administrative controls for managing node membership and PKI to secure private peer-to-peer business networks.
• Double-Spending Prevention - Prevents double-spending and ensures correct event sequencing without requiring global data broadcasting.
• Double Spending Preventions - Ensures the uniqueness of ledger entries to prevent the reuse of state and double-spending.
• Certificate-Based Authentication - Implements a public key infrastructure using digital certificates to manage network membership and peer authentication.
• Public Key Identity Providers - Implements a public key identity provider that governs network membership and authenticates peer nodes.
• Public Key Infrastructure - Manages the certificate hierarchy and public keys required for secure communication across the business network.
• Trustless Consensus Coordination - Coordinates agreement flows between network participants to validate transactions without global broadcasting.
• Digital Asset Lifecycle Management - Implements a framework for designing and controlling the full lifecycle of tokens and financial instruments.
• Consensus Workflow Coordinators - Coordinates communication and negotiation between network participants to reach consensus on transaction state.
• Smart Contract Automations - Executes JVM-based business logic to automate agreements and verify transactions on a distributed network.
• State Inspection Tools - Allows direct inspection of stored states, transactions, and attachments via a connection to the node database.
• Ledger Data Modeling - Uses a design language to specify ledger schemas and automate the generation of transaction logic.
• External Data Integrations - Integrates off-ledger oracle services to enrich transaction validation with real-world data.
• Historical Data Archiving - Implements strategies for offloading older ledger state and transaction records to secondary storage for auditability.
• Workflow Progress Monitoring - Tracks the execution flow and state transitions of distributed business processes via a management console.
• Automated Certificate Issuance - Acts as a certificate authority to sign join requests, revoke certificates, and authorize network map updates.
• Partial Data Visibility - Restricts the subset of transaction data visible to specific participants during the signing process to maintain privacy.
• Network Membership Controls - Provides administrative controls for managing node entry and certificate revocation to maintain a secure participant list.
• Oracle Service Integrations - Provides oracle service integrations to bridge on-chain logic with off-chain data sources for validation.
• Transaction Timing Validations - Verifies that transactions occur within specific time windows to meet business and regulatory requirements.
• Distributed State Recovery - Provides mechanisms to restore ledger data across participants to resolve synchronization failures and ensure consistency.
• Ledger Relationship Visualizations - Provides tools for mapping and analyzing dependencies between ledger states and transaction flows.
• Business Logic Testing - Ships tools for running unit and integration tests to verify business flow logic and environment calibration.
• Automated Contract Testing Suites - Provides an automated testing suite to verify that smart contracts and distributed workflows behave correctly.
