Will blockchains make account privacy more secure?

本文介绍了几种利用区块链技术保障资金安全的方法,包括SALT提供的安全贷款服务、ZCoin的交易隐私保护,以及DeepBrain Chain和Matrix在AI计算及解决区块链问题上的应用。

From the emergence of blockchain technology, many people think that our funds have been brought into a safety helmet. This idea is not groundless. Following the four blockchain technologies introduced in this article and the virtual currency, it can be verified whether this statement is true. same.

Salt will be a better secure loan

The salt project is called “Traditional Loan Protected by Password Security”. This safe and automated loan technology (SALT) is a member-based financial enterprise. Members are the main target of their services and they can also protect Funds and equity for all users who want cash loans.

In the slat lending platform, users can take advantage of Bitcoin and other cryptocurrency collateralized loans. Advocacy is to provide a mechanism to support investors' holding value while simplifying various aspects of the lending process and fully exploiting the power of the lump-centric loan market.

SALT not only supports digital wallet security loans, but also allows valuable items such as jewelry and contracts to be used for mortgage loans. Such operations are suitable for any individuals and companies that own assets. For the first time, the project has the same fuel as its name. It is the circulation currency of the platform salt.

ZCoin better protects transaction privacy

ZCoin is a cryptocurrency that protects the privacy of your account by using the zerocoin protocol. It is the first cryptocurrency that implements the zero-coin protocol and uses zero-knowledge proofs to ensure that the relevant address information of the parties to the transaction is not compromised.

The zero-currency currency uses the same technical parameters as Bitcoin. It takes 10 minutes to produce a block, and the total money supply is 21 million. The half-cycle of output is also the same as Bitcoin. It is halved for about four years.

DeepBrain Chain is a highly effective privacy protection platform

DeepBrain Chain is a blockchain-based decentralized privacy protection artificial intelligence (AI) computing platform. DeepBrain Chain is abbreviated as dbc, and dbc is also its token, which is a useful digital currency for users to “buy” computing power. DeepBrain Chain aims to provide a more efficient and cost-effective way for AI development. The low-cost system saves the company up to 70% of the computational cost, which provides users with higher profitability and a better user experience.

Not only that, because the transaction is in the online transaction ledger, and the online transaction uses digital security code encryption, so the data transaction environment is protected by encryption algorithms and smart contracts, and users can safely use it for transactions.

Matrix is the advanced power of blockchain

Matrix uses the most advanced AI technology to solve the current blockchain problem. Matrix AI Network's cryptocurrency has high speed, high availability and advanced security.

he above technologies and currencies, from loans to transactions, have played a protective role in accounting privacy. This kind of currency with strong potential has stopped many people from watching and investing in them.
