Tested for you: Legapol, a blockchain service for lawyers

Legapol is operational. Here is a small test of what you can do with it (with screenshots!)

Legapol allows signing, storing and certifying documents using the blockchain.

It can be used in internal work processes of a firm, and to access documents which have been electronically signed and registered.

An example in practice

This is Legapol administration dashboard and menus.

First of all I had to create 2 users (to have one who will send documents to another), and a folder to organize and upload documents.

Then I uploaded a document for signature. Once the upload was complete, I immediately received a text message on my smartphone, with a link to the document, and a 4-digits code to use as a signature. A signature is possible whether the document is “accepted” or “refused”.

Clicking the link brings me to a page where I can visualize the document.
Once the document is reviewed, one can enter the 4 digits code and press the relevant button (“accept” or “refuse”)


Once it is signed, a certificate is automatically appended to the original document. It is certifies 1// who is the signor, 2// his decision (accepted or refused), as well as 3// the date of the decision.
At the very end of the certificate, there is the hastag that identifies the registration on the blockchain (here, highlighted in yellow).

Now, let’s go to “Verification” section. Copy/paste the hashtag at the end of the certificates to verify and validate.

– Clicking on “verify” brings us to the following page, which is a record of the transactions.

By clicking the hash link, detailed information is available.

And that’s it !

I contacted Deep Block SAS, developper of Legapol, to get further details;

  • BigBLOCK, where transactions are recorded, does not require any mining fees: all transactions are  unlimited and free of charge  . However, their is a subscritption price to the Legapol service (around 30 euros/month for the starter pack).
  • Each transaction is audited by a bailiff at the end of each month, to validate the existence of the records in the BigBLOCK register
  • Deep Block company validates its security once a year by a specialized cyber security company, to comply with the best practices of the sector
  • BigBLOCK is a hybrid Private/Public Blockchain : Private because the consensus engine is developped and owned by Deep Block, and public because it is based on the open-source version of Ethereum and because the blocks explorer is publicly accessible.

DeepBlock SAS adds that – as the project does not include any aspect of tokenization – they did not recourse to ICO or fund-chasing in general,  but they financed the project with their income from the sales of their other products to customers and partners. One of these partner, The “Village of Justice” wanted to offer to the legal community a tool to present a blockchain application, and they naturally agreed with Deep block SAS to promote Legapol on their portal.

In Conclusion

With legapol, lawyers – as well as other legal professions – can use the blockchain as a certification tool which is directly integrated in a store-and-share cloud solution, with digital signature through a smartphone validation process.

As the signature allows either “acceptance” or “refusal” it can also serve in all collaborative and remote work processes, where a partner needs to validate documents submitted to him by his team.

I let you appreciate how this process can be transposed to your own business, and in a more global picture, how it could be used for communications in court procedures and general registration of documents whenever anteriority is needed.
