Building the network for on-chain reinforcement learning
We're creating the infrastructure layer that will enable a new generation of AI systems trained with verifiable, blockchain-based reinforcement learning—solving the fundamental trust problem that limits AI deployment.
Our approach is to build a decentralized network of blockchain-verified RL environments where anyone can develop, train, and deploy agents with cryptographic guarantees. This network will serve as the foundation for a new ecosystem of verifiable AI, removing the core limitation preventing adoption in high-stakes domains.
The current AI paradigm is fundamentally broken for mission-critical applications. Models train in black boxes with no verifiable feedback mechanisms, making them unsuitable for medicine, finance, legal systems, and any domain requiring certainty. Their impressive capabilities remain locked behind this verification barrier.
OpenBlock Labs is building the protocol layer that solves this through blockchain-powered reinforcement learning environments. Our network provides cryptographically verified data, immutable reward functions, and transparent training processes—enabling any organization to develop agents they can trust with their most important decisions.
This isn't just about better AI—it's about unlocking trillions in market value across every industry where verification matters. By creating the standard protocol for verifiable agent training, we're enabling an ecosystem where developers, companies, and researchers can collectively advance the state of trustworthy AI.
The network effects of this approach are profound. Each participant strengthens the ecosystem: developers create better environments, organizations contribute verified datasets, and researchers advance training methodologies—all built on a common infrastructure with cryptographic guarantees.
Our vision is to make verifiable reinforcement learning the standard for any high-stakes AI application, transitioning the industry from impressive but unreliable models to systems with provable guarantees. Through our network, we're building the foundation for AI systems that can be trusted with our most important decisions.
Our network consists of three interconnected components that enable a new paradigm of verifiable agent training:
Unlike traditional AI platforms, our network creates a virtuous cycle where every participant strengthens the ecosystem. Each new environment, training methodology, or verification technique becomes available to the entire network, accelerating the development of trustworthy AI systems.
This network approach solves the core coordination and incentive problems of AI verification—aligning all participants toward building trustworthy systems.
The implications extend far beyond individual products. By building the protocol layer for verifiable reinforcement learning, we're creating the infrastructure for a new generation of AI applications—ones that can operate in regulated industries, critical infrastructure, and any domain where verification is non-negotiable.
We're looking for exceptional engineers and researchers to join us in building this network.
High-impact roles for exceptional builders.
Creating the blockchain-powered gym for training AI through verifiable reinforcement learning
Blockchain-Verified Agent Training
OBL.dev is our first agent — an autonomous data analyst trained in blockchain environments that leverage four unique properties: rich public datasets, multi-agent interactions, deterministic execution, and verifiable reward functions.
Massive public datasets that capture real economic behaviors and interactions
Shared global state with many users interacting on the same database simultaneously
Cryptographically verifiable reward functions that guarantee training integrity
Advancing agent intelligence through reinforcement learning and verifiable data
We're OpenBlock Labs
A team of researchers and engineers at the intersection of AI and blockchain. Our mission is to build intelligent autonomous agents through reinforcement learning, with blockchains serving as verifiable environments for data validation and training.
Blockchains are uniquely suited to serve as the perfect training gym for AI. They provide massive public datasets, shared global state across many users, deterministic execution environments, and cryptographically verifiable rewards—all essential properties for advanced reinforcement learning. These characteristics enable us to train agents in environments where actions and outcomes are transparent, rewards are provable, and the complexity of real-world interactions is authentically represented. No other technology combines these properties in a way that solves the fundamental challenges of building trustworthy AI systems.
