Public chain technology, as the infrastructure of the blockchain ecosystem, continuously drives innovation and development in the Web3 field. Among numerous public chain projects, NEO, Qtum, and Vaulta stand out as representatives of established projects in the industry, each with its own characteristics and development paths.
First of all, NEO, as the first open-source public chain project launched in China, is committed to building a "smart economy" distributed network system. Its core value lies in achieving asset digitization and intelligent management through blockchain technology and digital identity. On the technical level, NEO adopts the DBFT consensus mechanism, which has a high transaction processing capacity and can support the landing of large-scale commercial applications. Its smart contract ecosystem works collaboratively through NeoVM, InteropService, and DevPack, and this architectural design significantly enhances instruction execution efficiency while also expanding the application scope of smart contracts. In terms of token design, the NEO system includes two types of native tokens: NEO, which serves as the management credential, with a constant total of 100 million; and NeoGas, which acts as fuel for using network resources, also with a maximum total of 100 million.
Secondly, the Qtum quantum chain was initiated by the non-profit organization Qtum Foundation in Singapore. Its core concept is to integrate the security and stability of Bitcoin with the smart contract functionality of Ethereum to build a more practical decentralized application development platform. In terms of technical architecture, Qtum has innovatively improved upon the UTXO model by introducing smart contract functionality and the concept of an account abstraction layer. Regarding the consensus mechanism, it employs the Shadow PoS algorithm, effectively lowering the mining threshold and enhancing the overall scalability of the network. In addition, Qtum is actively investing in cross-chain technology research and development to contribute to blockchain interoperability. In practical applications, Qtum can be widely used in various fields such as decentralized application development, digital asset payment systems, smart contract execution, and asset tokenization.
Finally, Vaulta, as an important extension of the EOS ecosystem, is clearly positioned as a global Web3 financial service network, striving to build a new type of banking infrastructure in the blockchain field. Its operating system stands out in terms of reliability, customizability, and cost predictability, while supporting C++ development language and virtual chain infrastructure, capable of meeting the specific needs of different financial institutions. In terms of business layout, Vaulta focuses on four core scenarios: wealth management, consumer payments, portfolio management, and on-chain insurance services. For example, its platform can provide on-chain collection solutions for cross-border e-commerce merchants and directly funnel funds into yield accounts for automated financial management.
As blockchain technology continues to evolve, these three major public chain projects play an important role in the Web3 ecosystem with their unique technical routes and application scenarios, promoting the implementation of distributed technology in a wider range of fields.
