What Is Holochain – Building Dapps Without Blockchain (HOT)

What Exactly Is Holochain?

Holochain is an open-source framework that enables a new kind of decentralized internet. It delivers a scalable and energy-efficient alternative to traditional distributed ledger technologies that use blockchain. Holochain also offers developers a comprehensive framework and toolkit for building decentralized applications (DApps) without relying on blockchain. On Holochain, these decentralized applications are called Holochain applications, or hApps.

Holochain applications are highly versatile, resilient, and scalable. They provide efficiency thousands of times greater than blockchain since they do not require tokens or mining. Holochain's primary goal is to facilitate human interaction through shared rules agreed upon by mutual consent. This approach removes the need for any central authority to impose or change those rules. As a result, peer-to-peer interaction gives users full ownership and control of their data, without interference from large tech companies that might otherwise collect, sell, or compromise it.

By owning their data, users gain unprecedented agency and can do more with their information. For example, users can benefit from truly personal AI designed to serve them instead of the creating corporation. This user-centric model fosters composable, customizable applications that prioritize privacy and individual autonomy.

Whereas blockchains typically require tokenization, currencies on Holochain are optional. They work best when issued through peer interactions—such as ratings—or via double-entry accounting systems.

What Is the Difference Between Holochain and Blockchain?

To understand how Holochain differs from blockchain, it's important to look at each technology's features and underlying architecture.

Blockchain

Blockchain technology debuted with Bitcoin. It processes transactions in blocks across a network. Each transaction produces a unique hash; any change to the block alters the hash, signaling that a different transaction has occurred. All transactions are publicly broadcast to every node on a ledger, ensuring transparency. Each block also references data from the previous block, creating an unbroken chain and an immutable transaction record.

Holochain

Holochain, by contrast, is a newer distributed ledger technology that fundamentally challenges legacy systems. In Holochain, nodes independently verify transactions without requiring global consensus. Each node maintains its own ledger and uses network protocols to determine the validity of transactions. Once verified, this validity is retroactively shared network-wide. If a node acts maliciously, it is quickly blacklisted, protecting the integrity of the ecosystem.

Key Differences Between Holochain and Blockchain

Both Holochain and blockchain are decentralized, but Holochain is designed for greater dynamism and speed. Blockchain decentralizes transactions to facilitate direct user interaction without intermediaries. Holochain, however, distributes these interactions even more efficiently among users.

With Holochain, users can execute unlimited transactions per second across distributed networks, resulting in a vast, unrestricted network. In contrast, blockchain networks depend on a single system for transaction initiation and validation, which leads to higher fees and computational load as the chain grows.

Holochain nodes each run on their own chains, providing greater computational capacity and removing the need for miners. This setup reduces transaction fees to a minimum and eliminates mandatory tokenization. Instead, smart contracts enforce rules on the platform.

Blockchain uses a "data-centric" approach, leveraging consensus algorithms such as Proof-of-Work (PoW) or Proof-of-Stake (PoS) for global or majority consensus. Holochain takes an "agent-centric" approach, employing distributed hash tables (DHT) using rrDHT, so each node independently verifies and confirms transactions. These verifications are randomly broadcast across the network, enabling peer validation and ensuring data integrity by exposing any changes or invalid transactions.

Is Holochain Scalable?

Holochain is theoretically infinitely scalable as a decentralized application network. Its architecture specifically promotes high scalability and efficiency, without the limitations common to blockchain systems. Since each participant maintains their own chain, the network can process numerous transactions without requiring every node to reach consensus on each one.

Overall transaction throughput is determined by the number of nodes in the network. Because each node manages its own ledger, network congestion does not occur during transaction validation. As more nodes join and earn rewards for hosting dApps, the network can handle more simultaneous transactions. This scalability makes Holochain especially compelling for applications that require high throughput and low latency.

What Is Holo?

Holo acts as the bridge between Holochain and the broader internet. It is a distributed peer-to-peer platform that hosts hApps and connects them to the web, making decentralized applications accessible to mainstream users. Anyone can join the Holo network by sharing unused storage and computing power through the Holo Host app or dedicated HoloPorts devices.

To reward resource contributors, Holo issues HoloFuel—the project’s native, asset-backed, mutual-credit currency. This incentive model motivates participation and helps build a strong, distributed hosting infrastructure, driving the expansion and adoption of Holochain applications.
