In the 2021 bull market where DeFi and NFT almost occupy all the attention, the development of the underlying technology of the blockchain is also making substantial progress: while Ethereum is moving step by step to the Ethereum 2.0 of the Proof of Stake (PoS) consensus mechanism, the representative is more The advanced technology Casper public chain officially launched the mainnet on March 31, marking a milestone step.

“The existing Layer-1 protocol rarely meets the needs of enterprises, developers, and consumers to apply the blockchain without sacrificing the unique decentralization and security of the blockchain,” Casper co-founder and CTO Medha Parlikar pointed out in an interview with Lianwen. Some blockchain protocols increase efficiency by randomly sampling the validator population, thereby reducing security; some protocols have a very limited set of verification nodes or all are proxies, and these nodes either require permission or have a high threshold; some protocols Relying on sub-chains or shards as the main expansion method means that the total amount of network pledge cannot form a consensus, which reduces economic security. Since the shards cannot be completely combined, multiple attacks may be encountered. In addition, almost all protocols are subject to DDoS attacks.

Medha Parlikar said, “The Casper network is the first real-time PoS public chain built on Casper CBC, and the first Layer-1 protocol to achieve efficient expansion without sacrificing decentralization and security. Casper design goals It is to accelerate the adoption of blockchain technology by today’s enterprises and developers, and to meet future user needs through continuous evolution. We firmly believe that the enterprise-level functions and developer experience that Casper brings to the industry will surely promote mainstream enterprise adoption Blockchain technology.”

This self-confidence of Casper stems from Casper’s research on the basis of CBC Casper, one of the expansion plans of Ethereum, from the beginning of 2019. With the addition of Dr. Daniel Kane, one of the most famous mathematicians in North America, as a consensus protocol consultant, this cutting-edge research has become even more powerful. CBC Casper’s upgrade program Highway protocol was designed and officially released in January this year and passed a security audit.

Most PoS blockchains are designed using Byzantine Fault Tolerance (BFT) consensus protocol. The BFT protocol refers to the ability of the blockchain network to efficiently and repeatedly generate consensus among a group of distributed autonomous nodes. The BFT consensus model assumes that the number of dishonest nodes in a network does not exceed 1/3. Under the assumption that there are 2/3 honest nodes, the BFT blockchain can operate safely for a long time and maintain the immutability and verifiability of its transaction history. Casper’s Highway protocol is not only a safe and active consensus model under the BFT concept, but also two important improvements: First, it makes the network deterministic (Finality) threshold higher; second, it can achieve the typical BFT model cannot Reachable flexibility (Flexibility).

Mrinal Manohar, co-founder and CEO of Casper, said that the advanced BFT consensus mechanism design makes Casper the most advanced, safe and reliable smart contract platform in the PoS public chain. At the same time, Casper has a series of advantages that are welcome by developers, enterprises and users. : First of all, it is developer-friendly. The Casper virtual machine can translate the Solidity programming language, allowing Ethereum-based projects to be safely and easily transferred to Casper. Casper also provides an open coding standard to support Rust, Assembly, Script, and all languages ​​that can be compiled into WebAssembly (WASM) to attract nearly 30 million developers around the world to immediately develop decentralized applications, not just the blockchain field Secondly, it is user-friendly. Its Gas charging model allows users to predict the current network usage cost when using the Casper network, so that gas fees can be controlled. For developers on the Casper chain, in terms of transaction fees With complete flexibility, you can allow the sender to pay and the receiver to pay. The DApp itself can prepay and design any changes or percentages. This allows developers to create any type of infrastructure; the third is permission-free and flexible, enterprises can create private or licensed blockchain applications on the Casper network, while enjoying the confidentiality of the private chain and the security of the public chain; The fourth is that it can be upgraded. Casper can directly upgrade smart contracts on the chain without the need for complex ecological communication and migration processes in other public chains.

At 23:00 on March 31st, the Casper mainnet was officially launched, producing the first genesis block. 54 genesis nodes will be launched at the same time. As the mainnet goes online, more Casper verification nodes will also be launched. As a Casper network token, CSPR, like other PoS blockchains, plays a key role in value measurement and transaction media when rewarding verification nodes to run the network and maintain its security, developers/enterprises/users to use Casper to pay for Gas, and to conduct transactions. . CSPR with a total supply of 10 billion was publicly funded on the well-known crypto crowdfunding platform Coinlist in late March. More than 300,000 people from all over the world registered to buy it. The amount raised was more than 100 times. In the end, more than 50,000 people successfully purchased 1.6 billion. CSPR, Casper successfully raised 32 million US dollars. This largest and most popular token sale in history has made Casper a more widely distributed and more decentralized Layer-1 protocol from day one.

Entering 2021, Casper has not only made milestone progress in technology research and development, network operation, but also announced important cooperation with Metis, BSN, PlasmaPay, ACDX, IPwe, Covalent, BitGo, Threefold and other companies in the past three months. DAO, blockchain services, digital payments, derivatives, patent registration, data access on the chain, asset custody, distributed storage and other application scenarios have made solid progress.

At the same time, Casper is actively building communities around the world, especially in the United States and China, and will supervise an important funding plan through the Casper Federation and DEVxDAO to promote the development and application of developers on Casper, and jointly establish the ecological construction of Casper.
