Overview

Welcome to BON Docs (Build On Nexa): your onboarding gateway to building powerful applications, services, and ecosystems on Nexa.

Whether you’re just getting started or already working on a project, BON provides the resources, tutorials, and tools you need to build confidently.

Why Build on Nexa?

Actively Growing

Since our fair launch in 2022, Nexa has listed on major exchanges like Bitget, MEXC, BingX, Biconomy, Coinstash, and more. Our vision is to become a decentralised global payment network optimised for usability, transparency, and mass adoption. Every project built on Nexa strengthens this mission and supports a network that is primed for exponential global penetration and growth.

Global Vision

  • Scalability: Nexa’s unique PoW algorithm and UTXO architecture can scale to 10+ billion transactions/day — enough for the whole planet.

  • Security & Reliability: Built on the proven UTXO model outlined by Satoshi Nakamoto, with key improvements for global scalability and long-term stability.

  • Predictable Costs: Deterministic fees and no blind-signing risks common to account-based chains.

Reliable Brand

Nexa is developed and maintained by the same world-renowned blockchain engineers who helped build Bitcoin Cash. Our team works under Bitcoin Unlimited, a non-profit dedicated to advancing global peer-to-peer money.

Nexa’s Architecture

At the heart of Nexa is a combination of Proof-of-Work (PoW) consensus and the Unspent Transaction Output (UTXO) model — the same foundational architecture that powers Bitcoin, but optimised for global scale, programmability, and developer flexibility.

UTXO: Transparent, Scalable, and Flexible

Unlike account-based systems, Nexa’s UTXO ledger tracks every coin as an output of a prior transaction, enabling scalability and independent validation.

  • Efficient Auditing – Funds can be verified independently, without reliance on centralised authorities.

  • No Blind Signing – UTXO design inherently prevents these risks as all of the inputs and outputs of the transaction are specified upfront.

  • Privacy & Flexibility – Outputs can be split or merged, allowing flexible transactions without exposing the same wallet address.

By combining the real-world anchoring of PoW with the efficiency and scalability of UTXO, Nexa provides developers with a secure, future-proof foundation for programmable peer-to-peer applications at global scale.
