CERTIFICATION IN NFT MARKET

A non-fungible token (NFT) is a unique and non-interchangeable unit of data stored on a digital ledger (blockchain). NFTs can be associated with easily-reproducible items such as photos, videos, audio, and other types of digital files as unique items (analogous to a certificate of authenticity). NFTs use blockchain technology to provide a public proof of ownership. Copies of the original file are not restricted to the owner of the NFT, and can be copied and shared like any file. The lack of interchangeability (fungibility) distinguishes NFTs from blockchai files

Non-fungible tokens or NFTs are cryptographic assets on blockchain with unique identification codes and metadata that distinguish them from each other. Unlike cryptocurrencies, they cannot be traded or exchanged at equivalency. This differs from fungible tokens like cryptocurrencies, which are identical to each other and, therefore, can be used as a medium for commercial transactions.

Much of the current market for NFTs is centered around collectibles, such as digital artwork, sports cards, and rarities.

Perhaps, the most obvious benefit of NFTs is market efficiency. The conversion of a physical asset into a digital one streamlines processes and removes intermediaries. NFTs representing digital or physical artwork on a blockchain removes the need for agents and allows artists to connect directly with their audiences. They can also improve business processes. For example, an NFT for a wine bottle will make it easier for different actors in a supply chain to interact with it and help track its provenance, production, and sale through the entire process.

INTERCER certifies the content encrypted in NFT, with two objectives:

- Ensure the NFT owner the integrity, suitability and truthfulness of the NFT information

- Assure the buyer of the NFT of the veracity, suitability, integrity of the information of the NFT received

SMART CONTRACT AUDIT

A smart contract audit is a security check done by cybersecurity professionals meant to ensure that the on-chain code behind a smart contract is devoid of bugs or security vulnerabilities.

A smart contract audit is an extensive methodical examination and analysis of a smart contract’s code that is used to interact with a cryptocurrency or blockchain. This process is conducted to discover errors, issues and security vulnerabilities in the code in order to suggest improvements and ways to fix them. Generally, smart contract audits are necessary, because most of the contracts deal with financial assets and/or valuable items.

Such checks are complex, as smart contracts often interact with each other and any integrations with third-party systems can also result in making the system vulnerable. Because of this, the checks are often expanded to other smart contracts involved in any interactions, and even those that the ones it interacts with are interacting with. Such checks usually include both running tests and manual code analysis.

TOKEN CERTIFICATION

Federation servers require token-signing certificates to prevent attackers from altering or counterfeiting security tokens in an attempt to gain unauthorized access to federated resources.

The private/public key pairing that is used with token-signing certificates is the most important validation mechanism of any federated partnership because these keys verify that a security token was issued by a valid partner federation server and that the token was not modified during transit.

INTERCER works in two areas of certification:

1.- Blockchain / Token-signing certificate requirements

2.- Certify the content of the Token, in terms of information, integrity and veracity.

WALLET CERTIFICATION

Wallet is used to store the public and private keys necessary to carry out transactions. The public key is a series of numbers similar to the bank account number and is used as an address to which the crypto assets will be sent. The private key works as a key for the exclusive use of the owner with which he can carry out the movements within his virtual wallet. These keys always remain within the device that operates them and are not related to the data of the cryptocurrencies, they are also accompanied by a digital signature to verify that the funds are transferred by the owner.

There are also non-custodial and custodial portfolios.

A non-custodial wallet allows the user to be the sole manager of their keys through the use of series of words known as seed, this type of wallet being the most secure.

On the contrary, custodial wallets do not allow the user to manage their passwords since these are controlled by the service in which the transactions are carried out and, in general, they tend to be more insecure.

LEDGER CERTIFICATION

Ledger's hardware wallets are device-based, which means they use storage mechanisms—USB drives—to store private keys, thereby making it difficult for hackers to access the key from an online location.

BLOCKCHAIN DATA CERTIFICATION (only for private blockchain node)

A blockchain, as a decentralized, resilient and forgery-proof registry enables integrity certificates to be generated in minutes, in a secure manner and at a lower cost than existing solutions such as the e-soleau envelope, which requires the certified content to be revealed to third parties.

Moreover, evidence created on a public blockchain will never be erased, even if your certification provider were to disappear, the evidence would remain accessible.

What is the legal value of a blockchain certification?

Today, the certification of a digital file on a blockchain constitutes the beginning of a proof, like an email. Thus two conditions must be respected:

1. Guarantee the identity of the person who initiated the certification

2. Keep a certified version of the file

The certificate established on blockchain will allow before a judge to prove the integrity and the anteriority of a data or digital file.

Sectors of activity concerned are numerous. Here is a selection with concrete examples:

Health: certification of digital medical prescriptions + pharma

Medicines production batch to batch

Pharmaceutical products

Public sector: certification of intregrity of information

INTERCER provides services for the parametering and certification of massive data encrypted in blockchain technology in order to assure third parties the suitability of the data, its veracity and its identification.
