What solutions does DoxyChain offer?

DoxyChain is a blockchain-based platform for digital documents and credentials management. The two products DoxyChain offers are Certificates and eSign. Another integral part of the solution is Verifier where involved parties may check the status, validity and history of a particular document issued/uploaded onto the DoxyChain platform.

What is DoxyChain blockchain?

DoxyChain users don't have to be tech-savvy to use the platform. However, the backend of our platform is powered by an advanced technology. DoxyChain Team developed a proprietary blockchain infrastructure specifically for document management. Built on Tendermint Core, with a Proof-of-Authority consensus mechanism, it might connect to other blockchains and is fully interoperable.

At DoxyChain we also developed our own DSL (Domain Specific Language) - a specialized language created for writing advanced smart contracts for document management and digital credentialing.

On top of this blockchain infrastructure, we built a user-friendly platform for certificates and document management to leverage security and automation in the space.

Is DoxyChain platform available via a mobile app?

Yes! DoxyChain mobile apps are available in App Store and Google Play.

What types of documents can I sign with DoxyChain eSign?

Any type of document. From contracts, applications, offer letters, sales contracts, real estate contracts, permission slips, rental/lease agreements , liability waivers, financial documents etc...

Can I delete a file?

Using blockchain means you can't delete a file. But you can easily archive it.

I have more questions, where can I get answers?

We have a chatbot on our system, whether you are registered or not you can ask anything that hasn't been answered here.

Is e-signature feature intended for personal or business use?

DoxyChain e-signature can be used for both personal and business purposes. The system is abstract enough to add and sign any document. The only documents that are signed on our platform are not legally binding are those that should be drawn up in the presence of a notary.

What are the three main advantages of DoxyChain e-signature?

1. Immutability — blockchain technology guarantees that all actions performed on the document will be indisputably secured. Thanks to this, our system is fully transparent.

2. Privacy — archived documents will be safe, and stored independently in several locations in the European Economic Area. What is more user activities within the DoxyChain system are secured and executed by smart contracts. Blockchain is not only used as a database - instead, smart contracts manage all business logic.

3. Time savings by collaborating on a contract with a B2B/B2C client or within a team and minimizing printing and document storage costs.

4. (*) Interoperability — possibility to connect with other blockchains.

5. (*) Ownership — user data in their own hands.

How does e-signature work in DoxyChain software?

1. Create an account on the platform by providing an email address and phone number (two-step verification).

2. Add a new document with an e-signature.

3. Upload the selected files of which the document will consist. We accept files in PDF, DOC/X, JPG, PNG and ZIP formats. If the file to be signed is in another format, it should be zipped.

4. The system adds the document to the blockchain network and displays a screen to invite recipients.

5. You can invite signers to the document both from inside your workspace and from outside by entering their email addresses. You can also invite users in other roles: viewer and administrator. This can be useful if you want to grant access to the document to the auditing entity.

6. People designated by the document administrator can join the document after logging into the system and signing it.

7. Once signed by all, the document assumes the state of being signed.

8. If the document you added is wrong or another party doesn't want to sign it, both the signer and the administrator can reject it.

9. You can download the original files from which the document is composed.

10. You can also download the document card which is the legal confirmation of the signatures on the blockchain.

Are DoxyChain e-signatures built on blockchain technology?

Our blockchain, which is built on Tendermint Core, is unique in the world. It was designed to have business processes in which broadly understood documents appear.

Can you just make an e-signature or can share it with others?

You can also add users in other roles, such as viewers. Blockchain will provide us with the assurance that a person has been granted access at a specific time.

How is DoxyChain different from other e-signature vendors?

Can DoxyChain e-signatures be used on mobile devices?

Yes, can be used both through a browser and through a mobile app available on iOS and Android.

What document formats does DoxyChain support for e-signatures?

We accept files in PDF, DOC/X, JPG, PNG and ZIP formats. If the file to be signed is in another format, it should be zipped.

Are DoxyChain e-signatures legally binding?

Yes. Our blockchain-based electronic signature is legally valid and compliant with the eIDAS regulation, the Durable Medium Directive, as well as GDPR. But you have to remember that it is not a qualified signature in the terms of polish law.

DoxyChain signature, in addition to all the advantages of SES and AES signatures, gives its users, through the use of blockchain technology, an unmatched certainty of the document flow and complete security of stored documents.

Where DoxyChain stored files?

The files attached to the documents are stored securely and encrypted on servers within the European Economic Area.

Why can't the signatories be edited once the signing has started?

The ability to edit signatories is blocked when the first person signs the document. This is done to preserve the integrity of the document.

Each person signing the document must know the identities of the other signatories and they cannot be changed once the previous signers have signed. This provides assurance to all signatories that the agreed content of the document will be signed by the designees who approved it.

Remember that it is always possible to add people in the role of administrators or viewers, regardless of the status of the document.

Why should I use blockchain technology?

The solution we provide puts security and transparency in the first place. That's why we use blockchain technology.

The data in the blockchain is verified, encrypted, and stored in a common distributed ledger (database) of transactions, rendering any attempt to alter the records ineffectively, while providing a single but shared source of truth about the origin of the certificate.

Our blockchain which is built on Tendermint Core is unique in the world. It was designed to have business processes in which broadly understood documents appear. We enable our clients to easily migrate towards transparency.

What is a digital certificate?

A digital certificate is a document stored and signed on the blockchain. With this technology, we can get rid of paper versions or enhance them with a new layer of security.

The certificate can easily be verified using the dedicated DoxyExplorer application. This allows you to confirm the authenticity of the product and the identity of the organization issuing the certificate. In addition, the certificate can be directly linked to a physical object using a QR code or NFC technology.

As most organizations share their documents via email and other centralized methods, where data is susceptible to cybercrime. By using blockchain-based digital certificates, product owners can securely confirm the authenticity of their physical assets.

How is DoxyChain different from simple PDF solutions?

Digital signatures stored on the blockchain live independently of the object to which the signature relates, which means that the signature is stored in a tamper-proof distributed registry and not in the PDF file itself.

The blockchain-based solution uses only cryptographic records of the files of which the document is composed without interfering with its content. Classical (not blockchain-based) solutions add signatures to the original files modifying them, which is undesirable. Once a record is added to a block, its contents are immutable, which means that any modification to the signed file can be discovered in a simple manner.

This implies that there is no need for a central certification authority or a central time stamp server, as time stamping is inherent to the blockchain - this applies to the document itself and each signature.

It is always possible to check who signed a document, when, and in what order without the need for the participation of intermediaries.

Why do we need blockchain when issuing certificates?

The certificate confirms the authenticity of the product. Nowadays, it is very difficult to check whether a document has been forged – blockchain is a solution.

Thanks to the distributed ledger nature of blockchain technology and its ability to track every change or transaction performed, it allows verification in real time. Anyone with access to a digital certificate can authenticate the information and source mentioned.

DoxyChain brings trust and transparency into the market by offering the highest possible level of security and making use of contemporary technological advancements.
