NanoTrust is a technology platform that generates tamper-proof documents. When creating a document, the document issuer can use NanoTrust to generate a digital twin of this document. Part of the information contained in this document (chosen by the creator of the document) is used to create a signature that will be registered in the Tezos blockchain.
The digital twin includes a QRcode which makes it possible to invoke the blockchain and bring up the authentication information which was chosen by the creator of the document when it was created. Thus, anyone receiving this document can invoke the blockchain to verify that the document presented is indeed authentic.
It is a real revolution in the portability of digital documents which are increasingly falsified.
Today the NanoTrust platform is not open to individuals. Only holders of a document justifying a legal entity (Kbis for France) can use NanoTrust to create digital twins.
As an employee, if you wish to benefit from documents certified by Nanotrust (pay slip for example), you must ask your employer to create an account on the Nanotrust platform to generate these authentic documents for you.
An "issuer" is a legal person (company / association) that issues an authentic document by generating a digital twin. An issuer has an account that has been verified by NanoTrust
A "beneficiary" is the person who receives a Nano, i.e., a document authenticated by the NanoTrust platform. A beneficiary can accept or refuse this Nano. By accepting it, the Nano is added to his personal wallet at Nanotrust. The beneficiary can then generate a presentation of this Nano to share it with a third party ("ultimate beneficiary").
At the end of the chain, the ultimate beneficiary is the one who receives the certified document (Nano) sent to him by the beneficiary. He can invoke the blockchain to ensure the authenticity of this document.
Any document can become verifiable with NanoTrust.
We support the following document types as standard:
The personal data used to create the NanoTrust account is stored on NanoTrust servers (hosted in a secure environment at AWS in Europe).
Personal data contained in authenticated documents are also stored on NanoTrust servers (hosted in a secure environment at AWS in Europe).
What is recorded in the blockchain is only the signature (signature: concatenation of the information present in the document to be authenticated – signature which is not decodable. It is impossible to regenerate personal information from a signature).
In order to be able to issue Nanos on behalf of your company, you must present some information allowing you to attest to your "authority" on this account. So, you will have to deposit in our platform: a registration document of your company (Kbis for France) and an identity document.If your name is not in the Kbis, the KYC process will take a little longer and we will ask you to provide a delegation of signature. You will be contacted by the Nanotrust teams in charge of account verification.
The Nanotrust platform works by subscription. When creating your account, you choose a business plan for a monthly or annual period. Each plan gives you access to the production of a finite number of Nanos per month and some offer you extensive functionalities within the platform. It is possible to upgrade a plan.
The subscription is monthly; however you have 3 months to use your Credits. NanoTrust automatically uses the oldest credit when creating a Nano.
If you want to cancel your subscription to NanoTrust, just write to us at firstname.lastname@example.org . Withdrawals from your account will be suspended immediately. The current subscription will remain valid until the end of the subscribed period (month / year).
Your invoices are available in your personal space within the Nanotrust interface. You can download it in pdf.
A Nano is a document (physical or not, abstract or tangible) that is signed into a Verifiable Credential.
The credential acts as a digital twin that can be transferred digitally to its owner, the subject of the credential.
This credential can then be presented (in its entirety or just a part) to a third party so that the authenticity of the document and its content can be instantly proven.
A "wallet" is a secure storage application for digital assets linked to a blockchain. In order to facilitate access to secure documents issued via the NanoTrust platform, Nanotrust provides beneficiaries with its own web wallet. It consists of three elements: an address within the Tezos blockchain (tz_xxxxxx), a public key (series of numbers) and a private key, known only to the owner of the wallet. This private key makes it possible to sign transactions and to prove to all the peers of a network that one is indeed the owner of such or such document (verifiable using the public key which is shared).
In a few months, it will be possible to port the assets contained in the Nanotrust wallet to other wallets supporting the Tezos chain (Kukai for example).
The DID is the unique identifier that is generated when creating your profile within Nanotrust. Its encoding follows the rules of protocols related to controlled identities (Self-Sovereign Identity or SSI) defined worldwide by the W3C. This DID can be used outside of Nanotrust.
An NFT (Non-Fungible Token) refers to a digital file to which a digital certificate of authenticity has been attached. More precisely, the NFT is a cryptographic token stored on a blockchain. The digital file alone is fungible, whether it is a photo, video or otherwise, the associated NFT is non-fungible.
The Nanotrust platform makes it possible to generate NFTs that fall into the category of Utility NFTs. The primary purpose of these NFTs is not speculative but probative. The transfer of ownership is subject to constraints imposed by the issuer.
The smart contract that we put in the blockchain is called an anchor. He is there to ensure, later, that the document presented is indeed the one that was written on the date of writing.
It is composed of the address of its owner and the signature of the document. This signature is generated by taking the information from the document and by operating a mathematical function (sha256 or other) with the public key of the issuer of the document as a parameter. This function is particular since its properties are to be irreversible, idempotent and for almost similar parameters, it will provide a totally different result. The slightest change in the document (even a letter or a pixel) therefore gives a different signature. This is the guarantee of authenticity.
What is recorded in the blockchain is only the signature (signature: concatenation of the information present in the document to be authenticated – signature which is not decodable. It is impossible to regenerate personal information from a signature). Our smart contract defines the rules of life of the "signature" in the blockchain.
The NanoTrust smart contract is recoverable in its personal dashboard in the detail of each Nano. The address of the smart contract is presented there, and a link is to an indexer (for example TzKT) makes it possible to find the smart contract in the Tezos blockchain and to see its details.
No. Only the "signature" is recorded in the blockchain. It is impossible to reproduce your data from the signature.
The certificate will be "minted" in the Tezos blockchain (https://tezos.foundation). It is one of the 10 largest blockchains in the world, renowned for its reliability and eco-responsibility.
Initially, the certificate once generated will be hosted on a NanoTrust web wallet which will be created for the beneficiary when creating his account (ie when he asks to receive his certificate). In a second step, the holder will be able to port their NanoTrust certificate to other wallets supporting the Tezos blockchain: kukai (https://wallet.kukai.app/), Temple (https://templewallet.com/)

The steps required to be able to issue Nanos are :
You receive your Nanos directly in your wallet within the NanoTrust platform. When a new Nano intended for you is generated, you receive an email. You then have the choice to accept it (it will then be "minted") or to refuse it.
As a beneficiary, if I refuse a Nano, it will not be "minted" in the blockchain. It will not be added to your wallet. It will be listed as "refused" in the issuer's wallet. If you finally want to accept it, you will have to make a request to the issuer to generate a new one for you.
The NanoTrust platform uses "proof of stake" blockchains, which consume little energy. Today the blockchain used to generate certificates is Tezos, reputed to be one of the least energy-consuming in the world. (https://tezos.com/carbon/). It is estimated that the mintage of a Nano generates 2.5gr of CO2. By way of comparison, according to ADEME in 2022, sending an email via a computer generates an average of 17gr of CO2 equivalent.
Any entity (person, organisation, government, ...) can issue a Nano. They can do it with the NanoTrust platform (the easiest) or any other tools compatible with the Verifiable Credential standard.
A nano makes it possible to prove the origin and the authenticity of an information.
You can present the Nano (or part of it) with a third party that will be instantaneously able to verify (and thus trust) that proof.
Nanos and Verifiable Credentials allow anyone to share information in a secure, privacy-aware, controlled, and tamper-proof way with a third party.
You should issue Nanos whenever you are in a position to state an assertion about yourself or other subjects, and you want that assertion to be easily, instantly, and permanently verifiable by the people it is being shared with.
Examples of relevant Nanos range from diplomas delivered by a school to their students to invoices issued by contractors to their clients, going through internal assessments, audits, government-issued identification cards, or passports.
Verifiable Credentials are statements made about a subject.
This subject, which is often the owner, can be anyone, from yourself to another person or even a group of people.
When you create a Nano via the Nanotrust tools, you provide that subject's email address and name.
They receive an email asking for their consent to receive that Nano, and if they agree, it is added to their wallet.
