Allium has dumped a major cache of indexed blockchain history onto Walrus — bringing more than 65 TB of standardized, finance-ready datasets from Bitcoin, Sui, Ethereum, Arbitrum, Tron and XRP to the verifiable on-chain data layer.
The data drop is part of a new partnership between Allium — the analytics platform used by customers such as Visa, Stripe and Coinbase — and Walrus, the verifiable data platform developed by Mysten Labs (the team behind layer-1 Sui). Walrus flagged the launch on Twitter, noting these are indexed, production-ready tables rather than raw chain blobs.
Why it matters
- Institutions get institutional-grade, auditable blockchain data with built-in availability and on-chain verification — important for compliance, risk management and high-stakes finance.
- Builders and researchers gain direct access through dashboards and developer tools, lowering the friction to query and integrate historical chain activity.
- Walrus sees a particular upside for AI agents: the datasets can be discovered, purchased and consumed autonomously, enabling agents to incorporate structured blockchain signals into workflows or models.
“Data that underpins high-stakes financial decisions needs a foundation you can verify,” Walrus Foundation managing executive Rebecca Simmonds said. “Allium already serves some of the biggest names in fintech, and they're now delivering data through Walrus—making it verifiable, always available, and with programmable access built in. This is validation of our thesis that mission-critical data belongs on Walrus.”
Allium’s CEO Ethan Chan framed the move as an experiment in distribution: the company is publishing selected datasets via Walrus to test decentralized infrastructure as an additional channel for institutional-grade blockchain data.
How the technical stack works
Walrus already emphasizes verifiability and resilience — it claims to have stored more than 450 TB of unencoded data since launch less than a year ago — and the partnership builds on those core features like redundancy in the face of node failure and on-chain proofs of integrity. Allium’s datasets on Walrus also tap Seal, a decentralized secrets-management service, to encrypt data and enable programmable access. That lets data be encrypted and unlocked at the point of purchase without a centralized intermediary — effectively turning datasets into programmable assets that quant funds, analytics firms or AI agents can buy and use on demand.
What’s next
Both teams characterize this as the start of a longer-term collaboration. Allium says more institutional-grade, indexed datasets from leading chains will arrive on Walrus in the coming weeks and months, widening the pool of auditable, developer-friendly blockchain data available for finance, AI and on-chain analytics.
