Despite major advances in blockchain technology, the industry still struggles with key limitations: scalability bottlenecks, high energy consumption, and increasing centralization risks tied to mining power or validator control. As networks grow, these issues become harder to ignore, pushing developers and researchers to explore new, different architectures.
That’s why Arthur Brock and Eric Harris-Braun created Holochain, an open-source framework that challenges the traditional blockchain model entirely. Instead of relying on a global ledger shared by all users, Holochain takes an agent-centric approach, where each user maintains their own chain and only shares data when necessary.
But can Holochain replace traditional blockchains in 2025?
What is Holochain and How Does it Work?
Holochain is a post-blockchain framework designed for building fast, scalable, and peer-to-peer applications without relying on centralized infrastructure or global consensus. While it supports the same goals as blockchain decentralization, security, and transparency, it takes a fundamentally different path to get there.
At the heart of Holochain is an agent-centric architecture. Rather than using a single, global ledger like Bitcoin or Ethereum, each user (or “agent”) runs their own independent copy of an application.
Your identity and data are stored locally on your device, and all the actions you take are signed with your private key and tracked in your own personal source chain. Only when necessary is data published to a shared distributed hash table (DHT) for others to validate or reference.
This is not just a design preference; it’s what allows the agent-centric blockchain to eliminate the need for mining, staking, or energy-intensive consensus protocols. There’s no global ledger to synchronize and no “truth” that the entire network must constantly agree on.
Instead, each user follows shared validation rules, and mutual accountability, backed by cryptographic proofs and audit trails, ensures integrity without central enforcement.
Holochain also creates encrypted, peer-to-peer networks on a per-app basis. This means every application connects users directly, empowering collaboration and real-time interaction without dependence on cloud servers.
Users benefit from the autonomy and responsiveness of local software, combined with the redundancy and reach of distributed systems. Developers, in turn, don’t have to manage or pay for hosting; each user helps carry the network.
Because of this unique architecture, this agent-centric blockchain is particularly well-suited for lightweight and collaborative applications, such as social networks, supply chain tracking, identity systems, and reputation tools, where data sovereignty and scalability matter more than global financial consensus.
How Does Holochain Work?
Unlike traditional apps hosted on centralized servers or blockchains requiring consensus from the entire network, Holochain distributes authority and responsibility to every participant. Here’s how it works:
Individual Agency
At the heart of every Holochain app is you, the user. Instead of connecting to a central server or syncing with a global ledger, you run your own copy of the application. Your identity, data, and activity live on your own device, and nothing is shared or published without your explicit consent.
Every action you take, whether it’s creating a post, recording a transaction, or updating a profile, is cryptographically signed using your private key. This signed data is stored in your personal source chain, a kind of tamper-proof journal that proves your authorship and behavior without needing third-party approval.
This setup gives you full data ownership, offline resilience, and a computing experience that’s both private and powerful.
Shared Rules
While everyone maintains their own chain, the app enforces shared validation rules, a kind of distributed social contract. These rules define what “valid” behavior looks like (e.g., how messages should be formatted or how interactions should be recorded) and ensure that every peer in the network can independently validate each other’s actions.
Each user has a local copy of these rules built into their application. When someone tries to publish data to the shared network (the DHT), peers use these rules to check whether the data follows the protocol. If it doesn’t, the network rejects it, automatically and impartially.
This model enables mutual accountability without a central authority. Bad actors are quickly detected and can be flagged or isolated, making it hard for them to disrupt the system.
Mutual Sovereignty
In a Holochain app, no one user is above the rest. Everyone has the same capabilities and responsibilities, creating a decentralized balance between freedom and accountability. This principle is called mutual sovereignty.
Since all users validate each other’s actions, no central server or miner needs to enforce the rules. And because each node operates independently, the system is highly resilient; if one node goes offline or behaves maliciously, the network keeps working just fine.
This structure allows the agent-centric blockchain to scale naturally as more users join, all without introducing the bottlenecks or energy costs typical of blockchain systems.
In essence, Holochain apps are collaborative ecosystems where users are in full control, the rules are transparent, and trust is enforced through architecture, not authority. It’s a radically different way of thinking about how apps should work in a decentralized world.

Holochain’s Limitations
While Holochain offers a fresh and powerful approach to decentralized computing, several challenges could limit its mainstream adoption, especially in a blockchain-dominated space.
Lack of Smart Contract Compatibility with Existing Blockchains
Holochain doesn’t support traditional smart contracts like those built on Ethereum, which limits direct compatibility with the majority of DeFi and Web3 platforms. Most developers are familiar with Solidity and its robust tooling.
Since Holochain uses a different model based on Rust and custom validation logic, dApp creators often have to rethink their logic entirely, which can slow down adoption and deter builders looking for fast deployment paths.
Harder to Port DeFi/NFT Apps Due to Lack of Token Standards
Blockchains like Ethereum thrive on shared token standards like ERC-20 for fungible tokens and ERC-721 for NFTs, which simplify interoperability across apps and platforms. Holochain avoids a global consensus layer and does not include built-in token primitives.
As a result, developers must create custom logic for managing digital assets, identity, or value exchange, which adds complexity and reduces composability.
Fewer Enterprise Integrations Compared to Layer-1 Blockchains
Ethereum, Solana, and other Layer-1 chains have spent years building enterprise-ready infrastructure, SDKs, APIs, support services, and grants that attract businesses, governments, and institutions. Holochain, while promising, is still maturing in this area.
It lacks the same level of developer onboarding tools, documentation depth, and proven enterprise partnerships, making it less attractive for organizations looking for stable, long-term integrations. Until Holochain expands its ecosystem and support systems, enterprise adoption may remain limited.
Market Perception: Still Seen as “Experimental” or “Too Academic”
Holochain’s different architecture can be hard to understand for both the public and professionals used to blockchain norms. This often leads to it being perceived as experimental or unproven, especially because there are still few widely used apps or commercial deployments built on the platform. Without high-profile case studies, investor confidence and developer interest can lag, even if the technology is technically sound.
Conclusion: Can Holochain Relegate Traditional Blockchains?
Holochain isn’t aiming to dethrone Ethereum, Solana, or Bitcoin in the race to power decentralized finance or global value transfer. Its architecture lacks a native token layer and doesn’t support smart contracts in the traditional sense, so it’s not designed to replace Layer-1 blockchains that serve as financial infrastructure.
But that’s exactly the point. Instead of competing head-on, Holochain offers a different model: one that removes the need for global consensus and embraces user autonomy, local validation, and peer-to-peer resilience. This makes it uniquely suited for decentralized applications focused on collaboration, identity, governance, and real-time data, areas where blockchain can be overly slow, expensive, or inefficient.
Holochain isn’t trying to be the next Ethereum; it’s trying to be the foundation for a new kind of internet: one where apps are user-owned, lightweight, and serverless. And if it succeeds, that shift could be just as transformative.
