Against the backdrop of the thriving Web3 industry, the Sign project has become a focal point in the industry due to its innovative business model and substantial profitability. In 2024, the project achieved a remarkable revenue of 15 million USD, making it one of the few profitable infrastructure projects in the Web3 field.

Sign Protocol, as a core component of the Sign ecosystem, is hailed as a pioneer of the 'global on-chain verification infrastructure.' It employs a decentralized proof mechanism, allowing users to verify information such as identity, contracts, and assets in a cross-chain environment. The protocol integrates blockchain technology, zero-knowledge proofs, and Arweave storage solutions to build an efficient and secure data verification system.

The practical applications of this technology are very extensive. For example, users can generate zero-knowledge proofs by simply scanning their passports with their mobile phones, allowing them to complete identity verification without exposing sensitive information. This innovative approach shows great potential in the construction of government digital infrastructure.

In 2024, Sign Protocol has been implemented in several countries, including the UAE, Thailand, and Sierra Leone, covering multiple areas such as electronic visas and digital identities. Notably, in Sierra Leone, Sign Protocol has enabled the world's first blockchain-based electronic visa system, significantly improving administrative efficiency. These successful cases not only demonstrate Sign's technical strength but also bring stable revenue sources to the company.

According to official data, the number of proofs for Sign Protocol is projected to experience explosive growth in 2024, increasing from 685,000 to over 6 million, nearly a 9-fold increase. This astonishing growth rate highlights the strong demand and widespread recognition of the technology in the market.

As digital transformation deepens, the application prospects of Sign Protocol in government and enterprise digital infrastructure are broad. It not only enhances the efficiency and security of data verification but also provides innovative solutions for cross-border collaboration and identity management. It is foreseeable that as more countries and institutions adopt this technology, Sign Protocol will play an increasingly important role in shaping the future digital world.
