How useful it is to issue digital certificates on the blockchain?

Blog content:

Blockchain technology is used in several ways in varied industries for offering high-security managing distribution systems and recording valuable information. Blockchain records all transactions without any verification from third parties. An evolving issue in recent years is - counterfeiting certification. It is posing serious threats to people. Issuing paper-based certificates manually is prone to errors and time- consuming. Day by day, the number of people's data is increasing, so deploying a system for both issuing and verifying digital certificates based on blockchain technology can solve issues of forged documents.

What is the current problem with document certification?

Many organisations and businesses need original documents for verification purposes before further processing. Some valuable documents like (birth certificates) exist only once. Parties involved in verification and issuing other certificates may experience hesitancy to handle these sensitive documents and that can result in damage or even loss. Many parties are unable to protect the valuable physical pieces of paper with this process. Another big problem comes from data theft. Many people have reported it. So the question comes: how can this issue be solved? Creating digital proof or digital certificates certified or signed by respective institutions or authorised organisations can be beneficial. With blockchain-based digital certificates, you can access and verify the digital asset's authenticity without depending on any intermediary or third party. Traditional data records like paper files deteriorate over time. storing records like digital certificates on the blockchain can help in safeguarding sensitive credentials from destruction & damage. Blockchain document security methods can help users seamlessly secure their sensitive documents.

What about blockchain solutions?

Blockchain technology has brought a revolution in storing and sharing data. The mechanism of cryptography helps in keeping information fully secured. Blockchain offers a digital ledger or decentralised database of data. Centred on computer networks that approve updates before data get recorded and verified. It lessens the reliance and vulnerability of centralised data storage. Instead of handling physical pieces of documents, issuing and storing digital certificates in blockchain can be advantageous to users. You can efficiently utilise the benefits of blockchain, like - authentication, encryption and decentralisation. Every certificate consists of references of both issuer and receiver with a hash (a sign of document), that is stored in the public database. It is identical in the number of computers throughout the globe. These digital certificates with blockchain technology have vital additional advantages over any other certificates.

How does blockchain make digital certificates work?

When a digital certificate is issued, data gets digitised. A digital identity gets assigned to every certificate. All of the digital certificates are tagged as well as traceable. Original documents are stored safely in the computer networks in the blockchain which are known as nodes. In totality, blockchain makes digital certificates highly transparent and secured. It also makes it easy to unfurl any fraud because this technology can expose any forged or outdated certificates.

Are these digital certificates tamper-proof?

Yes, the digital certificates are tamper-proof not by just signing but right after the beginning of the transaction. A signing algorithm produces a signature that is encrypted through a private key. The digital signature in these certificates can never be forged without having access to the private key of the user or members. With the help of document security QR codes, users can secure their valuable credentials.

What are the potential benefits of issuing digital certificates on the blockchain?

Blockchain has evolved to be beneficial for the financial industry. This technology is the most talked about and sought-after technology used in the world. There are innumerable benefits of issuing digital certificates on the blockchain. Some of them are here: a) Require fewer resources for issuance: Issuance and maintenance of digital certificates on the blockchain require a very less number of resources. As a result, the whole process saves time, effort and human capital. b) Digital certificates are conveyable: Contrary to physical certificates, the digital ones issued on the blockchain need not be carried around every place. Digital certificates are there to exist for a lifetime. These certificates can be easily accessed on any of your devices from any part of the world. c) Ideal as Identity proof: Digital certificates based on blockchain are the best substitution for the traditional proofs of paper identification. Digital certificates are issued on a highly secured framework of blockchain which is fully secured. These verifiable certificates can be easily traced all the way back to an issuer. This method makes the procedure transparent. You can use the blockchain document security method for securing and storing your valuable documents. d) Gives overall data security: Paper certificates can also take days and months to get issued and dispatched. Paper certificates can be altered without issuing the institute's knowledge and that is risky. Digital certificates issued on the blockchain can not be altered by any person. If someone tries to tamper with it, then verification will fail. This makes data in your digital certificates fully secured as well as traceable. e) No third party requirement: Blockchain verification of digital certificates can be performed by any person having access to the network. There is no need for any third party interference for verification. Digital certificates can be verified even if any organisation that issued them no longer exists. f) For micro-credentialing: Every data remains encrypted in the digital certificates issued on the blockchain. Organisations or businesses can issue "micro-credentialing" for recognizing, career skills, learning and so on. It can help both students and organisations. g) Comes at an affordable cost: Using blockchain is not expensive. With the help of the blockchain-powered platform, you can issue digital certificates for numerous services with ease. You may need no extra software or hardware and be done with an internet connection. So in nutshell, the unique features of blockchain technology make issuing digital certificates easy and tamper-proof. Blockchain technology simplifies and facilities the entire process of issuance of digital certificates. It also helps in the easy transfer of these certificates leading to the expansion of contents and information. We hope in the next few years, more and more organisations will come forward in embracing digital certificates issuance on the blockchain. A blockchain document security system can help you to secure sensitive credentials with ease.

What is Zero-Knowledge Proof and How is It Connected with Blockchain?

Posted on December 2, 2021

Though Blockchain technology is a trustworthy option for obtaining the desired privacy and security of information exchange, it includes transparency, sometimes, as a setback. Hence, Zero Knowledge Proof (ZKP) has is emerging as one of the protuberant solutions for attaining the requirements of transaction confidentiality.

What Do You Mean by Zero-Knowledge Proofs?

Cryptography has been linked to blockchain technology as one of the most crucial components since its beginning. Cryptography on blockchain technology is the main reason for its huge-scale adoption across diverse industries for various companies. The ZKP Blockchain applications came into existence because of new cryptography-protocols, and mechanisms based on different mathematical foundations.

The beginning of zero-knowledge proof shows a new chapter in the arena of cryptography. It is one of the most protuberant examples of cryptographic innovation with different applications, encompassing file security, secure and anonymous transactions on public blockchain networks and nuclear decommissioning.

How Do Zero-Knowledge Proofs Work?

The functionality of ZKP aims at permitting a prover to persuade a verifier about a particular fact without revealing real information. For example, you can check the balance in your bank account without any need to access your bank details and any personal information. Zero-knowledge proof can help in achieving this outcome by leveraging its three significant traits. The three crucial aspects characterizing a ZKP encompass the following,

Completeness of the transaction is crucial. It simply implies that the reality of a statement persuades the verifier that the prover has ownership of the needed input.
A crucial trait in the design of a ZKP is soundness. It means that it shows that a fraud prover fails to persuade the verifier that he has the needed input when their statement is untrue.
The final factor in the design of a zero-knowledge proof is all about zero knowledge. The main indication of the zero-knowledge aspect in ZKP underlines non-disclosure of information. Even though the statement is true or false, the verifier should not learn anything about the data.

How Can a Person Use ZKPS in Blockchain?

Maybe ZKP blockchain interdependent relationship has not been discussed enough. However, industry leaders, experts, and decision-makers are identifying the value of ZKPS. The point is the scalability of ZKPS can enable the growth of blockchain technology while even offering the assurance of flexibility to users, coupled with enhanced control and freedom linked to their information. Hence, it is unavoidable to think about the possible ways in which ZKPS is altering the blockchain arena. To know how zero-knowledge proof is modifying blockchain technology, have a quick peep into the diverse areas in the blockchain system where ZKPS is appropriate.

Messaging Applications

End-to-end encryption has played a crucial part in enabling messages to be sent privately. However, conventional messaging applications need users to confirm their identity to a server. With ZKP’s, a person can prove his identity without releasing any extra personal information.

Complicated Documentation

Blending ZKP’s and blockchain technology permits users to share complicated documents with security. ZKP’s have the power to encrypt data in pieces. It allows users to control specific blocks and the visibility of the information contained inside them. It permits some users to access while limiting others.

Just like ZKP’s, you can find another alternative solution by ProofEasy. It ensures security and that too without the revelation of any personal or confidential information. For example, secure QR codes like ProofEasy Global QR Codes are dynamic and different. It has blockchain-based technology, and it does not ask for any information from the users. Blockchain technology places a hashtag in the secure QR code that is immutable. Whenever someone wants to access the data or information or make a transaction, the blockchain technology matches the hash value of the QR code with the hash value registered on the blockchain network. The hash value contains biometrics like fingerprint, and no more information stays therein. Hence, no matter who you are and how much you know about technology, it is easy to use for you to make your documents, procedures, or anything secure and immutable. The unique hash value of the Secure QR code promises document safety that too without exposing any personal or confidential information. You can even use encrypted QR code generator to produce the QR for protecting your document or file. Furthermore, try guarding your transaction data or documents or other procedures with future proof Secure QR-code.
