CurveBlock
Hyperledger Besu is an enterprise grade Ethereum client that CurveBlock uses to record and manage digital shares because it combines permissioned network controls privacy options and compatibility with Ethereum tooling while meeting the operational and auditability needs of a regulated fund that is approved for Gate 1 of the Bank of England and FCA Digital Securities Sandbox and is not full FCA authorisation.
What is Hyperledger Besu?
Hyperledger Besu is open source software that implements the Ethereum protocol and is designed for both public networks and private permissioned networks. It runs as a node software that validates and broadcasts blocks records transactions and manages consensus among participants. Besu supports standard Ethereum primitives so developers can use familiar languages and libraries while operating in a controlled environment suited to enterprises and regulated markets.
Hyperledger Besu brings Ethereum compatibility into environments where governance privacy and performance matter.
Core technical features that matter for digital shares
Besu offers a set of technical capabilities relevant to issuing and managing digital shares. It supports permissioned network models so the operator can control which organisations run nodes and who can submit certain kinds of transactions. It includes configurable consensus choices that balance finality throughput and decentralisation which helps tune performance for a financial product where timely settlement and audit history are important. Besu also offers privacy frameworks that limit sensitive data visibility to specified participants rather than exposing all ledger entries to every node.
Compatibility with Ethereum tooling
Because Besu implements Ethereum standards developers can use mature tooling for smart contracts and wallets and auditors can apply familiar techniques when verifying ledger records. This compatibility reduces bespoke software risk and makes it easier to integrate with custody and reporting systems already used across the market.
Using an Ethereum compatible client reduces integration friction while keeping enterprise controls.
Why CurveBlock chooses Besu for managing digital shares
CurveBlock needs a platform that supports a regulated fund model offering pooled UK real estate and renewable assets with equal profit sharing per share and non expiring shares. Besu provides the right mix of enterprise features and open standards. Permissioned operation helps meet governance expectations because participant identities and roles are known and controlled. Privacy features let CurveBlock keep investor details confidential while still providing an auditable ledger for regulators and auditors. The software is mature and widely used in enterprise settings so operational risk is lower than with experimental frameworks.
Operational needs include reliable settlement workflow integration and the ability to present an auditable share register. Besu supports clear ledger histories and cryptographic proofs that are useful when reconciling records with corporate registries and custodians. That helps CurveBlock maintain a robust share record while allowing investors to hold and transfer digital shares with transparency.
CurveBlock is publicly described as approved for Gate 1 of the Bank of England and FCA Digital Securities Sandbox which signals regulatory engagement. It is important to state that this Sandbox approval is not full FCA authorisation and does not imply full regulatory permission beyond the testing environment. Besu helps meet the practical requirements that such a sandbox process examines because it supports permissioned access audit logging and consistent rule enforcement across nodes.
Besu aligns enterprise controls with open standards which supports the needs of a regulated digital share platform.
Privacy and permissioning in practice
For a fund platform privacy means investor personal data and trade details are not widely visible across an open network. Besu provides private transaction capabilities where transaction payloads can be shared only with designated participants while a hash or reference is stored on the common ledger. Permissioning allows an operator to decide which organisations run validators who can propose blocks and who can read particular records. This is particularly useful for a regulated provider that must satisfy data protection rules and confidentiality expectations.
Controlling who can see and validate records is essential for private investment structures.
Auditability operational resilience and performance
Besu produces transaction logs and block histories that auditors can inspect and verify. This supports the production of an auditable share register and helps show how profits and distributions map to holdings. Running a permissioned Besu network also allows CurveBlock to design operational resilience into the platform by distributing nodes across multiple providers and disaster recovery zones while keeping performance in a range appropriate for retail grade share management.
When investors transfer digital shares settlement times are influenced by consensus configuration node availability and integration with custody or payment rails. Besu lets operators tune these parameters to find the best balance between speed and the guarantees required by the fund governance model. For further detail on settlement mechanics see How digital share transfers settle and what affects the timing.
Transparency in ledger history combined with resilient node deployment supports dependable operations.
Integration with existing financial and audit workflows
Besu supports widely used cryptographic standards and audit approaches so it is easier to connect ledger records to trustee accounts custodian systems and fund accounting. That reduces the amount of custom plumbing needed to generate investor statements or regulatory reports. CurveBlock uses these integration paths to present reconciled investor records and to allow independent auditors to verify the integrity of ledger entries. For more on ledger records and investor trust see Auditable share registers what ledger records change for investor trust.
Bridging ledger records to familiar accounting and audit processes lowers operational friction.
Security design and governance
Security for a digital share register is not only about cryptography. It is also about who can change network rules who can run validator nodes and how upgrades are governed. Besu supports permissioning and configurable governance which allows CurveBlock to document upgrade processes control access to node operation and manage keys in line with industry best practice. Regular audits code reviews and secure key management complement the platform choice to reduce the chance of operational or security incidents.
Security combines software capability with clear organisational controls and audit routines.
Final points for investors and partners
Hyperledger Besu is not a silver bullet but it is a pragmatic choice for an entity that needs Ethereum compatibility and enterprise grade controls. CurveBlock uses Besu because it helps maintain a transparent auditable register of digital shares while allowing the privacy governance and operational resilience required for a regulated fund platform. The platform remains under regulatory oversight in a testing context and being approved for Gate 1 of the Bank of England and FCA Digital Securities Sandbox does not mean the platform has full FCA authorisation.
Choosing an Ethereum compatible enterprise client supports integration transparency and controlled governance.
Frequently asked questions
What makes Besu different from a public blockchain?
Besu can be run as a permissioned network where participation is restricted and privacy controls are applied rather than as an open public network where anyone can validate and view all transactions.
Can investors see every transaction on the Besu network?
Visibility depends on how the network is configured; CurveBlock uses privacy and permissioning so investor personal data and sensitive trade details are not broadly visible to all nodes.
Does Sandbox approval mean the platform is fully authorised by the FCA?
No, saying the platform is approved for Gate 1 of the Bank of England and FCA Digital Securities Sandbox is not the same as full FCA authorisation.
How are ledger records used in audits?
Ledger records provide cryptographic and chronological evidence of holdings and transfers which auditors can reconcile with fund accounting and custody records.
Will CurveBlock change the platform software in future?
Any changes to the network software would be governed and documented to ensure continuity of records and to meet audit and regulatory expectations.
