Blockchain Stamper, Wise’s technology in B2B Safe

The B2B Safe marketplace is the first marketplace to incorporate blockchain technology, thanks to Wise Security Global’s Blockchain Stamper solution. What does it do? It makes sure order confirmations are totally secure.

In the B2B Safe marketplace, the buyer and seller negotiate the conditions of different products and services until an agreement is reached. Blockchain Stamper ensures the entire negotiation process is totally secure: Who has done it, when was it done and what was the outcome. Once it is completed, the buyer can choose whether to secure the process through a certified contract, or through a certificate contract plus Blockchain Stamper.

Wise Security Global intervenes with its Blockchain Stamper solution, and with Getronics blockchain: AQQUM. The purpose of this solution is to certify all the actions taking place in the marketplace.

Our MEE the Cybernotary solution also intervenes throughout this process, providing the cryptographic layer to the whole process. So on the one hand, Blockchain Stamper will record the operation in the blockchain and, on the other hand, MEE signs and provides cryptography as a trusted third party certifying everything done by Blockchain Stamper.


The first thing we must do to create evidence is collect data: the time a certain operation tool place, who carried it out and what was the outcome. Once we have all that information, we record it in a document that we sign electronically. The result of this document or a summary of it will be uploaded to the blockchain.

Let’s get into the details of the Blockchain recording process: We don’t actually write the entire certificate in the blockchain, as this document does not need to be public. What we do is a cryptographic hash function on the certified record. It is the outcome of that, the summary, that we write in the blockchain.

(ESP) Blockchain Stamper, su uso en el marketplace de Crédito y Caución

El marketplace B2B Safe es el primer marketplace del mercado en incorporar tecnología blockchain, gracias a la solución Blockchain Stamper, desarrollada por Wise Security Global.

¿Qué se consigue con ello? Que las órdenes de confirmación de los pedidos queden totalmente securizadas dentro de este marketplace gestionado por Crédito y Caución.


En el marketplace B2B Safe, comprador y vendedor negocian las condiciones de los diferentes productos y servicios hasta llegar a un acuerdo. Con Blockchain Stamper todo el proceso de esa negociación queda totalmente securizado: Quiénes lo han hecho, a qué hora se ha hecho y cuál ha sido el resultado. Una vez termina, el comprador puede elegir si quiere securizar el proceso mediante un contrato certificado o mediante un contrato certificado más Blockchain Stamper.

Wise Security Global interviene con su solución denominada Blockchain Stamper, que utiliza la cadena de bloques AQQUM, de Getronics. El objetivo de esta solución es certificar todas las acciones que son llevadas a cabo dentro del marketplace.

En todo este proceso también interviene nuestra solución MEE the Cybernotary, que aporta la capa criptográfica a todo el proceso. Por un lado Blockchain Stamper notarizar la operación en la cadena de bloques, y por otro lado, MEE firma y aporta criptografía como tercero de confianza, certificando todo lo realizado por Blockchain Stamper.


Lo primero que debemos hacer para crear una evidencia es recabar datos de esa evidencia: a qué hora se ha realizado una determinada operación, quién la ha realizado, y cuál ha sido el resultado. Una vez tengamos todos esos datos, los consignaremos en un documento que firmaremos electrónicamente. El resultado de ese documento lo elevaremos a la cadena de bloques.

Realmente no escribimos todo el acta certificada en la cadena de bloques ya que ese documento no tiene porqué  ser público. Lo que realizamos es una función criptográfica de Hash sobre el acta certificada. Y ese resumen del acta es lo que escribimos en la cadena de bloques.
