OB1: The Foundational Blockchain LLM
OB1: The Foundational Blockchain LLM
Millions of users—many with limited technical backgrounds—engage in high-stakes blockchain transactions every day. While blockchain data is open and verifiable, making sense of it remains an unsolved challenge. The ecosystem is flooded with dashboards, data providers, and indexers, but data alone isn’t enough. The real value lies in reasoning—accurately interpreting user intents, predicting behaviors, and producing insights.
Enter OB1, the first blockchain-native large language model (LLM) focused on and designed to actively learn, simulate, and reason over on-chain activity. More than a query engine, OB1 transforms blockchain data into structured, deterministic knowledge—bridging the gap between static analysis and real-time, adaptive intelligence.
A New Era for Blockchain Intelligence
From Data to Reasoning
While data and data processing are vital, the blockchain space has no shortage of data-centric solutions. OB1 is a designed to process and interpret on-chain data across 30+ networks, including Ethereum, Arbitrum, Optimism, Solana, and emerging L2 ecosystems and integrates:
- On‑Chain Data: Blockchains are open ledgers full of verifiable, shared data. OB1 treats them as a rich dataset, integrating everything from transaction logs to smart contract events.
- On-Chain State Awareness: Real-time access to historical state, contract storage, and transaction mempools enables precise reasoning over blockchain interactions.
- Multi-Chain Data Aggregation: OB1 is integrated with event-driven indexers, allowing seamless cross-chain liquidity tracking, bridge validation, and risk assessment.
Yet, data without reasoning is just noise. A transaction hash doesn’t explain intent. A contract call doesn’t reveal expected outcomes. A user does not know what they are not aware of - OB1 aims to tackle this head on. Solution: Focus On The Reasoning Layer OB1’s performance isn’t just a product of scaling hardware—it’s built on a new paradigm for blockchain data interpretation with a key focus on the reasoning layer. OB1’s core features aim to create a model that optimizes interpreting and translating user intents into actions:
- Simulation as Intelligence: OB1 doesn’t just query on-chain data—it tests hypotheses. By simulating contract calls on local forks, OB1 compares simulated vs. real-world outcomes, adjusting its models to ensure precision. Cross-chain interactions, MEV flows, and DeFi strategies are no longer black boxes—OB1 reconstructs them step by step, verifying execution paths and potential failure modes.
- Active Learning: The Model That Gets Smarter: Every blockchain event is a learning opportunity. When its predictions differ from actual on‑chain outcomes, it learns and adapts—bridging the gap between theoretical reasoning and real‑world execution.
- Natural Language Meets Deterministic Blockchains: The complexity of multi-step, state-dependent blockchain interactions makes them difficult to interpret. OB1 explains its reasoning in plain language, ensuring transparency even for non-technical users. Whether optimizing gas fees, analyzing liquidations, or debugging smart contract logic, OB1 provides step-by-step, verifiable responses—bridging the gap between raw on-chain data and human decision-making.
Through improved reasoning, OB1 enables users to discover and surface what would normally be hidden insights, and seamlessly act on them.
The Openblock Labs Advantage
At OpenBlock Labs, we’ve spent years deeply immersed in crypto—designing points systems, structuring airdrops, and creating incentive models for leading DeFi projects and ecosystems. This extensive domain expertise gives us a unique edge in building OB1.
OB1 isn’t just another LLM trained on blockchain data—it’s built to reason within the realities of crypto ecosystems. It understands what and why liquidations happen, how arbitrageurs exploit price inefficiencies, and what motivates cross-chain liquidity flows.
