Introduction

Nubit is building the Trustless World Computer for Bitcoin, enabling open scaling through Bitcoin-native technology.

Computing has undergone a remarkable evolution over the past decades. Initially, it was characterized by proprietary applications running on individual local machines, which limited accessibility and collaboration. The 1990s and early 2000s saw the rise of open-source software, democratizing access and allowing users to run free applications on their personal computers. The subsequent shift to massive, multi-user applications hosted on proprietary cloud platforms offered unprecedented connectivity and convenience but introduced new concerns about centralization and control by dominant entities.

In recent years, the advent of blockchain technology has opened the door to decentralized networks, leading to a trustless, decentralized computing platform. Ethereum played a pivotal role in this evolution by introducing the idea of a "world computer," enabling programmable smart contracts on a global scale.

However, current implementations face persistent challenges in scalability, security, and true decentralization. Issues such as network congestion, high transaction fees, and vulnerabilities in smart contract code have highlighted the limitations of existing platforms. The need for a robust, universally accessible, and genuinely trustless computing platform remains unmet, particularly as we move toward a new era of autonomous interactions between humans and machines.

Bitcoin, the most secure and decentralized blockchain network, is uniquely positioned to serve as the foundation for the next-generation world computer. Its Proof-of-Work consensus mechanism and extensive network of nodes provide unparalleled resistance to attacks.

Bitcoin's simplicity and robustness have garnered trust from users and institutions globally. By leveraging Bitcoin's unmatched security and universal accessibility, enhancing its programmability and data capabilities can unlock a transformative era—Bitcoin 3.0—enabling seamless automation and interaction between humans and autonomous systems in Mankind-to-Machine (M2M) economies.

Despite its strengths, Bitcoin's network faces significant limitations that must be addressed to achieve the vision of a trustless world computer:

Limited Programmability: Bitcoin's intentionally restrictive scripting language limits its ability to support complex computations and advanced smart contract functionalities.
Storage Constraints: With a design focused on security, Bitcoin offers limited on-chain storage and high costs for data-intensive applications.
Scalability Issues: High transaction fees and slow confirmation times hinder the development of scalable applications.

To overcome these challenges, Nubit introduces a comprehensive infrastructure to transform Bitcoin into a trustless world computer:

BitVM for Advanced Bitcoin Programmability A comprehensive virtual machine that enables Turing-complete programmability on Bitcoin, allowing for complex computations and smart contracts. This innovation empowers developers to build dApps directly on the Bitcoin network.
Bitcoin-native Data Availability (Nubit DA) A solution to Bitcoin's storage limitations by enabling scalable data capacities with off-chain storage and on-chain verification. This ensures data integrity while significantly reducing the burden on the blockchain.
Goldinals A trustless framework for fungible tokens on Bitcoin, leveraging zero-knowledge proofs (ZKPs) and state commitments for full on-chain verification. Goldinals enables secure and decentralized applications like tokenization, stablecoin issuance, and DAO governance while preserving Bitcoin's principles of decentralization and security.
Formal Verification for Security Applies rigorous formal methods to ensure the correctness and security of Nubit's stack. By leveraging decades of expertise in mathematical reasoning, it minimizes risks, validates program behavior, and protects against vulnerabilities, enabling a robust and trustless ecosystem.
