Abstract
This report examines the infrastructure through which institutions observe blockchain state, submit transactions and participate in network operation. Covering nodes, remote procedure call (RPC) services, data and transaction routing, staking and controlled execution, it distinguishes network access, independent verification, custody and consensus responsibilities. It assesses sovereign operating models through the ability to verify, authorize, recover and switch suppliers, rather than server location alone. Reference architectures, a representative market comparison, illustrative cost models, stress scenarios and procurement tests connect technical choices with institutional accountability. Based on public sources retrieved on 30 September 2026, the analysis separates documented requirements, supplier-reported capabilities and IEI assessments; it does not present provider claims as independent assurance or propose universal requirements to operate nodes.
About this report
Blockchain Access as Institutional Infrastructure examines which capabilities banks, custodians, asset managers, market infrastructures and public institutions should control directly, which they can purchase, and what evidence demonstrates that the resulting arrangements remain reliable, accountable and substitutable.
The 48-page report connects network-specific technology choices with node management, RPC quality, validator operations and staking. It also examines intent forwarding, execution integrity, privacy orchestration, gas sponsorship and emergency intervention. Reference architectures and responsibility boundaries support a representative market comparison, illustrative economic scenarios, stress tests and an implementation and procurement programme. Appendices provide acceptance tests and a glossary.
The study uses public protocol, regulatory, institutional and supplier documentation; it does not include performance testing, institutional interviews or inspection of enterprise contracts, assurance reports and customer workloads. Proposed thresholds and budgets are illustrative, and the market review is a comparison of operating models rather than a provider ranking.
