Enterprise blockchain development has evolved rapidly over the past decade, and organizations today face a critical decision: which distributed ledger technology (DLT) and consensus protocol best align with their long-term goals? Popular options such as Ethereum, Hyperledger Fabric and Sawtooth, Quorum, MultiChain, and Corda offer varied capabilities. While enterprises can customize these protocols and build proprietary client DApps using in-house APIs and tools, doing so often leads to vendor lock-in—limiting flexibility and interoperability.
Although having multiple DLT choices fosters innovation, the lack of universal standards creates fragmentation. Enterprises within the same ecosystem may end up developing incompatible systems, making collaboration cumbersome. This is where open standards become essential—not just for technical compatibility, but for enabling trust, scalability, and industry-wide adoption.

The Role of the Enterprise Ethereum Alliance (EEA)
The Enterprise Ethereum Alliance (EEA) brings together over 500 member organizations with a shared mission: to establish open, standardized architectures that accelerate the adoption of Ethereum-based solutions in enterprise environments. By defining common practices and specifications, the EEA ensures that decentralized applications (DApps) built on one implementation can seamlessly interact with blockchains developed under another—provided both adhere to the same standards.
A pivotal moment came in October 2018 when the EEA and the Hyperledger Project—a well-known open-source blockchain initiative—announced a strategic partnership. Both organizations became members of each other’s communities, signaling a unified push toward creating interoperable enterprise blockchain frameworks. This collaboration strengthens the ecosystem by combining Ethereum’s smart contract capabilities with Hyperledger’s enterprise-grade tooling.
While adherence to EEA standards remains voluntary, following them offers clear advantages:
- Reduced development and integration effort
- Enhanced compatibility with third-party tools and services
- Faster deployment of scalable, secure blockchain solutions
- Support for industry-wide interoperability
Enterprise Ethereum Client Specification v2: Key Components
In late 2018, the EEA released Client Specification Version 2 and the Off-Chain Trusted Compute Specification v0.5, marking significant progress in standardizing enterprise blockchain implementations. These documents define how Enterprise Ethereum clients should be structured, ensuring consistency across different platforms while extending public Ethereum’s core features to meet business needs like performance, privacy, and permissioning.
The EEA Architecture Stack
The EEA introduced a layered reference model known as the Enterprise Ethereum Architecture Stack, which clearly separates components available on public Ethereum from those required for enterprise use. This stack comprises five distinct layers:
Application Layer
This topmost layer includes decentralized applications (DApps), monitoring tools, infrastructure contracts, governance frameworks (e.g., role-based access control), and development environments for smart contracts. It serves as the user-facing interface where business logic is implemented.
Tools Layer
This layer provides APIs that enable communication between clients and blockchain nodes. It also integrates with enterprise identity management systems (like LDAP or SSO) and supports deployment automation, configuration management, performance monitoring, security protocols, and historical data analysis.
Privacy & Scaling Layer
Privacy and scalability are critical for enterprise adoption. This layer introduces mechanisms such as:
- Zero-knowledge proofs (ZKP) for confidential transactions
- Layer 1 scaling via sharding and parallel transaction processing
- Layer 2 solutions including Plasma, state channels, and off-chain computation (as defined in the Off-Chain Trusted Compute Specification)
These technologies allow enterprises to maintain data confidentiality while improving throughput and reducing on-chain congestion.
Core Blockchain Layer
This foundational layer handles consensus mechanisms (e.g., Proof of Authority), block validation, transaction execution (both on-chain and off-chain), and data storage. It ensures network integrity and fault tolerance across distributed nodes.
Network Layer
Built on peer-to-peer (P2P) protocols like DEVP2P, this layer enables node discovery, message propagation, and secure communication. Future enhancements may introduce additional enterprise-specific P2P protocols to improve efficiency and security.

Off-Chain Trusted Compute Specification v0.5: Enhancing Performance & Privacy
One of the most impactful innovations introduced by the EEA is the Off-Chain Trusted Compute Specification v0.5. This framework allows enterprises to execute transactions outside the main blockchain—within trusted environments—and later submit only verified summaries back to the chain. This approach significantly boosts performance while preserving privacy.
Key enterprise use cases supported by this specification include:
- Conducting private transactions between mutually distrustful parties without revealing details to others on the network
- Selectively disclosing partial transaction data to authorized entities while keeping other information confidential
- Offloading high-volume or complex computations from the main chain to trusted execution environments (TEEs)
- Integrating oracles that provide verified external data for enterprise applications
The specification has been designed to work with three leading trusted computing technologies:
- Trusted Execution Environments (TEE) – such as Intel SGX
- Zero-Knowledge Proofs (ZKP) – enabling verifiable privacy
- Secure Multi-Party Computation (MPC) – allowing collaborative computation without exposing raw inputs
By supporting these models, the EEA ensures flexibility in implementation while maintaining strong security guarantees.
Why Open Standards Matter for Enterprise Blockchain
Open standards eliminate silos and promote innovation. When enterprises adopt EEA-compliant frameworks, they benefit from:
- Interoperability across platforms and vendors
- Faster time-to-market for DApps
- Reduced reliance on proprietary tools
- Access to a growing ecosystem of compliant software and services
Organizations like Chainstack actively monitor EEA developments to ensure their platforms remain aligned with these standards—enabling rapid deployment, monitoring, and management of enterprise blockchain networks.
