The second-layer test network Dango is online, a big benefit for Celo?

On July 7, the Celo Foundation announced the launch of its second-layer test network Dango. This action marks Celo’s deep integration with the Ethereum ecosystem and its grand vision for the future financial technology field. Driven by cLabs, Dango is not only a technological upgrade, but also heralds a major innovation in the global payment system.

It is reported that Celo was founded by a team with rich backgrounds, including industry veterans such as Rene Reinsberg and Marek Olszewski. Team members come from well-known companies such as Google, Coinbase and ConsenSys. Since 2017, Celo has worked hard to enable billions of smartphone users around the world to enjoy convenient cryptocurrency payments through its open financial system.

01. Build a mobile-first blockchain platform for global financial inclusion

Celo is a blockchain platform designed specifically for mobile devices and is committed to providing convenient and global financial services. Known for its unique lightweight identity and stability protocols, it aims to achieve one key goal: making financial decentralized applications (DApps) and cryptocurrency payment systems easily accessible to everyone with a smartphone.

The Celo ecosystem includes a decentralized proof-of-stake (PoS) blockchain technology stack, multiple native tokens, stablecoins, and an extensive Celo Prosperity Alliance. The platform supports smart contracts and is compatible with the Ethereum Virtual Machine (EVM), allowing developers to seamlessly deploy smart contracts and build DApps.

Compared with Ethereum, Celo provides lower mining fees and faster transaction settlement speeds, greatly improving operational efficiency and user experience, and through an innovative address-based encryption technology, users’ Phone numbers are mapped to public key addresses, which means users do not need to memorize complex public keys to conduct transactions and only need to use phone numbers. This feature greatly lowers the threshold for new users to enter crypto financial services.

What is even more user-friendly is Celo’s operating mechanism, which includes light clients, full nodes and verification nodes, which allows users to operate even in environments with small memory, weak computing power or poor communication bandwidth. Experience smooth cryptocurrency payments. Light clients are particularly suitable for mobile users because they do not need to store a complete copy of the blockchain, but instead connect to full nodes to process transactions and obtain necessary information.

At the same time, Celo has implemented a unique dual-token system, including stablecoins anchored to fiat currencies such as Celo Dollar (cUSD), Celo Euro (cEUR) and Celo Real (cREAL), as well as the platform’s native token CELO . This dual-token structure is designed to keep its stablecoin pegged by adjusting the supply and demand of CELO tokens. In addition, Celo's stablecoin mechanism includes reserves, Mento algorithms and over-collateralization to ensure that stablecoins can quickly return to their anchor prices when their value fluctuates.

02, Dango is online: a comprehensive exploration of the new payment experience

Dango test network was first proposed at EthCC in 2023, aiming to provide developers with a new platform so that they can test in an efficient and low-cost environment and optimize their projects. It is built on Optimism’s OP Stack, a technology framework known for its high scalability and excellent interoperability, providing solid support for the first layer of Celo while enhancing the overall functionality of the network.

This update inherits and enhances many of Celo’s original advantages, such as supporting actual payment solutions in more than 150 countries/regions, and bridging WETH and ERC-20 tokens between Ethereum and Celo. Greatly improve network scalability and efficiency. The new test network also shortened the block generation time from 5 seconds to 2 seconds and increased the total throughput by 50%, ensuring that global users can enjoy a faster and lower-cost payment experience.

먼저 토큰 브리징 기능

Dango는 WETH와 ERC-20 토큰 간의 브리징 기능을 특별히 강화하여 Celo와 이더리움 간의 자산 전송을 원활하고 편리하게 만들어 두 블록체인 생태계의 상호 운용성을 크게 향상시켰습니다.

둘째, 블록 완결성

1블록 완결성의 특성은 거래의 속도와 보안을 보장하는데, 이는 글로벌 결제에 특히 중요하며 매우 짧은 시간 내에 거래가 확정될 수 있도록 보장할 수 있습니다.

셋째, CELO 토큰의 유연한 사용

CELO 토큰의 이중 특성을 통해 개발자는 로컬에서 작동하든 ERC20 인터페이스를 통해 작동하든 관계없이 애플리케이션에 가장 적합한 상호 작용 방법을 선택할 수 있습니다.

마지막으로, 수수료 추상화 및 SocialConnect 통합

Dango가 도입한 수수료 추상화를 통해 USDT, USDC와 같은 Celo의 기본 토큰을 포함한 다양한 ERC-20 토큰을 사용하여 거래 수수료를 지불할 수 있으므로 사용 비용이 절감되고 증가합니다. 가용성.

동시에 Dango는 SocialConnect 기능을 통합하여 사용자가 전화번호, 이메일 주소 또는 소셜 미디어 식별자로 직접 자금을 보낼 수 있도록 하여 암호화폐 거래 프로세스를 더욱 간소화하고 사용자 친화적으로 만듭니다.

요약

Celo의 지속적인 개발 및 확장 전략은 전 세계 사용자의 폭넓은 참여를 이끌어냈을 뿐만 아니라 Andreessen Horowitz, Polychain Capital 및 비 영리단체 GiveDirectly. 이러한 노력을 통해 Celo는 글로벌 사용자에게 보다 안정적이고 포용적인 금융 생태계를 제공하겠다는 비전을 점차 실현하고 있습니다.

Dango 테스트넷의 성공적인 배포는 기술 진보를 반영할 뿐만 아니라 2024년 초겨울에 출시될 예정인 Celo 2층 메인넷의 견고한 기반을 마련합니다. 이를 통해 개발자는 최종 사용자에 대한 서비스에 영향을 주지 않고 광범위한 애플리케이션 테스트를 수행할 수 있습니다. 모든 중요한 인프라 제공업체가 노드 코드를 업그레이드함에 따라 Alfajores 테스트넷 업그레이드에는 새로운 포크가 필요하지 않으므로 테스트에서 메인넷으로의 원활한 전환이 보장됩니다.

Dango의 이정표가 완료됨에 따라 Celo 커뮤니티와 글로벌 개발자는 앞으로 더 광범위한 응용 프로그램 전망에 대한 기대로 가득 차 있습니다.
