Convergence of private & public

A new standard in private networks

HashSphere provides transaction privacy, flexible governance, and dedicated support, along with interoperability to other public and private networks through CLPR, a Cross-Ledger Protocol.

Why HashSphere?

Built with Hedera technology

Leverage trusted, enterprise-grade Hedera technology that is inherently secure, scalable and efficient to build tokenization solutions and more on a private network or Sphere with transaction privacy and security controls.

Network hosting optionality

Available as both a managed network service and self-hosted, users can monitor network performance, request services and support, restrict node operations to a specific country or cloud provider, as well as customize the number of nodes and size.

Transaction privacy

HashSphere delivers on-chain transaction confidentiality, while enabling atomic value exchange, such as DvP and PvP, as well as private transfers.

HashSphere explained in 1 minute

HashSphere is core privacy features that operate across every layer of the stack. These include: transaction confidentiality, independent network design, flexible validator and governance models, and mathematically guaranteed fair ordering through the hashgraph consensus algorithm.

PRIVATE BY DESIGN. INTEROPERABLE BY DEFAULT

Avoid vendor lock-in or trapped liquidity

HashSphere is designed for enterprises that require privacy, governance, and control—without creating isolated systems or long-term vendor lock‑in. It combines the benefits of private networks with native interoperability to the Hedera public network.

CLPR—Cross-Ledger Protocol

Interoperability without traditional bridges or validator networks

HashSphere integrates with CLPR, a bridgeless interoperability protocol that acts like a “postmaster” for blockchain networks and enables tokens, data, and messages to move between ledgers, such as Sphere-to-Sphere, Sphere-to-Hedera, or other public chains.

Cryptographic state proofs

The transfer of value is enabled by using cryptographic state proofs and threshold signature schemes (TSS), rather than maintaining pooled liquidity or trusted relayers.

Fast and Secure

Because HashSphere preserves each chain’s native consensus model, security assumptions are not weakened, and transfers complete as fast as the underlying networks reach consensus.

CONFIDENTIAL SETTLEMENT

Where privacy meets interoperability

Transaction privacy

DvP, PvP and direct transfer privacy leveraging zkSNARKs and ZKPs–all powered by an ERC-20 privacy SDK.

Secure and private + future interoperability

The network is not a ‘subnet’ on a public network. It operates as an isolated Sphere with asynchronous Byzantine Fault Tolerant (aBFT) security, EVM compatibility and enables interoperability through CLPR, avoiding isolated pools of assets.

Validator and governance optionality

HashSphere enables you to choose your own validator model without depending on a centralized authority. You control how your Sphere is governed and operated.

Consensus is achieved mathematically

Fair ordering and deterministic settlement are achieved mathematically with the hashgraph consensus algorithm without relying on external validators to order transactions.

What sets HashSphere apart

BENEFIT FROM NATIVE L1 SPEED AND SCALE

No trade-offs with L2s

With HashSphere, powered by Hedera, you get fair ordering and settlement finality through a native consensus model. Because the network defines the privacy boundary, there is no validator hierarchy and no need for ZK circuits for internal consensus.

DEPLOY ONCE. OPERATE ANYWHERE.

Private and public, without re-architecting

Applications built on Hedera can be deployed on HashSphere without additional development effort, enabling teams to move easily between private and public environments using the same tools and standards.

BUILD WITH FAMILIAR TOOLS

EVM-compatible by default

HashSphere supports Ethereum Virtual Machine (EVM)-compatible applications and smart contracts, enabling developers to build with Solidity and standard EVM tooling. Existing dApps from other EVM private networks can be deployed seamlessly.

CONFIGURABLE, COMPLIANT, AND PREDICTABLE

Institutional governance built-in

Define network participation, infrastructure preferences, and operational controls to meet regulatory, data residency, and security requirements without introducing new economic models or governance layers.

Open source as Hiero

The Hedera codebase that powers HashSphere has been contributed to Linux Foundation Decentralized Trust as Project Hiero, giving HashSphere users confidence that the technology will always be maintained by an independent third-party, and eliminating fears of vendor lock-in.
