I believe everyone should be familiar with blockchain technology, and today we will take a look at what issues we need to pay attention to in the field of blockchain technology security. Let’s start today’s The main content.

At present, most blockchain projects carried out within enterprises are so-called "private chains with permissions".

Unlike public chains, private chains can only be accessed by a selected group of users who have the authority to enter, verify, record and exchange data on the ledger.

Of course, for an "outsider" who has never been allowed to join, such a network is almost impossible to break.

But with the emergence of private chains, another question arises: In order to improve privacy and security, do we really need to abandon decentralization? From "MIT Technology Review" Mike Orcutt of Change.

” Such systems need to come up with balancing mechanisms to grant different levels of permissions to different groups of users and perform identity checks on validators to ensure they are who they claim to be.

That’s why many companies are looking for a way to have both—the decentralization of a public chain and the extra security of a private chain.

Consortium chains developed by major manufacturers such as IBM, Corda, and Ripple currently appear to be good security choices.

In short, they provide businesses with access to centralized systems that themselves have a level of cryptographic auditability and security.

Other companies are also considering how to adapt public chains to meet their security needs.

For example, the Ethereum blockchain already provides mechanisms that can be leveraged to ensure the privacy of network participants, including ring signatures, stealth addresses, and storing private data on the public chain.

In general, the blockchain field is developing steadily towards new solutions that define technology-granular privacy layers for public chains, private chains, and consortium chain networks.

IT Training/Discovery Companies are actively investigating and patching known vulnerabilities and adopting new mechanisms to ensure that all parties are protected and that no malicious hacker can break through and exploit vulnerabilities in the ledger. .
