  • Key features: Custom tokens, Nano Contracts, atomic swaps
  • Architecture: Based on a PhD thesis by co-founder Marcelo Brogliato

Introduction

Hathor (HTR) is a Layer 1 blockchain that takes a fundamentally different approach to scalability and usability. By merging a Directed Acyclic Graph (DAG) structure with a traditional Proof-of-Work (PoW) blockchain, Hathor enables fast, fee-less transactions without sacrificing security or decentralization.

The platform is designed to make blockchain accessible — allowing individuals and businesses to create tokens, deploy simplified smart contracts, and perform atomic swaps without deep technical knowledge or high costs.

History & Background

Hathor's development began in 2018, rooted in a novel blockchain architecture proposed in co-founder Marcelo Salhab Brogliato's PhD thesis at a Brazilian university. The first testnet went live in 2019, and the mainnet launched on January 3, 2020 — symbolically mirroring Bitcoin's own genesis block date.

The founding team includes Yan Martins (CEO), Marcelo Brogliato (CTO), Layla Mendes (CFO), Pedro Ferreira, and Jan Segre as senior engineers.

How Hathor Works

Hathor's architecture places transactions inside a DAG, while traditional mined blocks sit on top of the DAG and confirm them. During low-traffic periods, the blockchain layer ensures security. As transaction volume grows, the DAG takes over to maintain speed and scale.

This hybrid model allows the network to handle hundreds of transactions per second without a central coordinator. Security is reinforced through merged mining with Bitcoin and Litecoin, meaning miners can secure all networks simultaneously without extra energy costs.

Nano Contracts — Hathor's lightweight alternative to smart contracts — allow users to deploy programmable logic without writing code or managing gas fees.

Tokenomics

HTR is the native token powering all activity on the network. It serves as collateral for custom token creation: users lock a small amount of HTR to mint new tokens, which is refunded when those tokens are burned. This creates a natural demand mechanism tied directly to network usage.

Miners earn newly issued HTR as block rewards, ensuring ongoing decentralized distribution. HTR is also used to access Nano Contracts and participate in atomic swaps.

Ecosystem & Use Cases

Hathor supports a wide range of applications:

  • Custom tokens and NFTs — created without coding, requiring only a small HTR deposit
  • Atomic swaps — peer-to-peer token exchanges in a single transaction, no smart contracts needed
  • Nano Contracts — simplified programmable agreements for DeFi-like functionality
  • Tokenization platforms — for real-world assets, loyalty programs, and fundraising
  • Confidential Transactions with Selective Disclosure — combining privacy with auditability for enterprise use

Team, Governance & Community

Hathor is developed by Hathor Labs, a team with roots in academic research and blockchain engineering. The project is fully open-source, welcoming public contributions via GitHub.

The community is active across Telegram, Discord, Reddit, and Twitter. Governance decisions and development roadmaps are discussed openly with the community, reflecting the project's commitment to transparency.

Advantages

  • Zero transaction fees — no gas costs for users or businesses
  • High scalability — the DAG-blockchain hybrid handles 200+ TPS
  • Merged mining — leverages Bitcoin's hash rate for added security at no extra energy cost
  • No-code token creation — custom tokens and NFTs deployable without technical expertise
  • Built-in atomic swaps — protocol-level token exchanges without smart contracts
  • Optional privacy — confidential transactions with selective disclosure for compliance needs

Risks & Challenges

  • Adoption hurdle — competing against well-established Layer 1 ecosystems with larger developer bases
  • Nano Contracts maturity — smart contract functionality is newer and still maturing
  • Market visibility — limited awareness compared to major blockchain platforms
  • Merged mining dependency — network security partially relies on Bitcoin miner participation

Long-Term Vision

Hathor aims to become a foundational infrastructure layer for the next generation of digital applications — from tokenization platforms to AI-native systems. Its roadmap focuses on expanding Nano Contracts, advancing confidential transaction capabilities, and making blockchain development as simple and accessible as possible for builders worldwide.

Frequently Asked Questions

Hathor combines a DAG structure with Proof-of-Work mining to achieve high throughput and zero transaction fees. Unlike Ethereum, it requires no gas fees and lets users create tokens without writing smart contracts.

HTR is the native token used to pay for network operations, act as collateral when creating custom tokens, deploy Nano Contracts, and reward miners who secure the network.

Miners can mine Hathor simultaneously with Bitcoin and Litecoin using the same computational work. This shares Bitcoin's hash rate with Hathor, boosting security without additional energy consumption.

Nano Contracts are Hathor's lightweight alternative to traditional smart contracts. They allow users to set up programmable on-chain logic simply and without needing advanced coding skills or gas fees.

Yes. Users can create custom tokens and NFTs on Hathor without any coding knowledge. A small amount of HTR is locked as collateral during minting and is refunded when the tokens are burned.

Hathor's mainnet launched on January 3, 2020. Development began in 2018 and was grounded in an academic blockchain architecture proposed in co-founder Marcelo Brogliato's PhD thesis.

Yes. Hathor supports Confidential Transactions with Selective Disclosure, which allows transaction data to remain private while still being auditable for compliance purposes.

Transactions are placed inside the DAG, while mined blocks confirm them from above. The DAG absorbs high transaction volumes to maintain speed, while the blockchain layer ensures long-term security.
