❶ What is the model of blockchain?

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. . Blockchain (Blockchain) is an important concept of Bitcoin. It is essentially a decentralized database. As the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. , each data block contains a batch of Bitcoin network transaction information, which is used to verify the validity of its information (anti-counterfeiting) and generate the next block.

The biggest problem if such technology is to be put into application is the "impossible triangle problem"

That is, it cannot achieve scalability (Scalability) and decentralization () at the same time. , Security (Security), you can only get two of the three.

Most of the public chain projects currently on the market are difficult to put into use on a large scale.

If there is a public chain project that can solve this problem, it will be a revolution in the blockchain.

Backed by the world’s first and largest encrypted digital currency payment platform and wallet solution with a user base of more than 3 million, Velas (Virtual Expanding Learning, virtual expansion autonomous learning system) is a Artificial intelligence (AI)-optimized neural networks enhance its consensus algorithm, self-learning and self-optimizing public chains, and are committed to improving the security, interoperability, and high scalability of the transfer process and smart contracts. Velas uses AI-enhanced DPoS consensus to achieve complete decentralization without reducing security and transaction speed.

Velas has recently launched the Velas desktop wallet and web wallet

Velas web wallet

Velas web wallet allows users to process transactions within their web browser Cryptocurrency, purchase Velas token VLX, and support easy viewing of detailed history of all wallet transactions. Login credentials have an additional layer of security with two-factor authentication feature.

In addition to the basic functions of creating and restoring wallets based on mnemonic strings, all data stored in the Velas web wallet is encrypted using the RSA-256-CBC algorithm to ensure that user data is not compromised by the system owner. or stolen or misappropriated by external attackers.

A prominent feature of the web version of the wallet is that it supports exchanging VLX tokens for other cryptocurrencies within the wallet, and the wallet will continuously refresh the current VLX exchange rates for all fiat currencies for users’ reference.

Velas Desktop Wallet

Velas Desktop Wallet is a highly secure wallet program suitable for Windows, macOS, and Linux operating systems. The desktop wallet also uses the same mnemonic feature as the web walletand RSA-256-CBC encryption algorithm.

Unlike the web version, which is an online wallet, the Velas desktop wallet allows users to store their wallets directly on their computers, avoiding potential risks of online attacks, including phishing, IP fraud and XSS. It is worth mentioning that both the desktop and web wallets provide users with an automatic lock option for security issues. If they are not used for a long time, they will need to enter a password when logging in again before they can access again.
