For business is based on Multichain, holding different types of assets with any describing metadata. It stores information in a distributed and decentralized way, and the information can never be erased. It has an incorruptible digital ledger of transactions shared by participating nodes. Blockchain is modeled for commercial networks with privacy.


What is Blockchain technology?

The blockchain technology consists of replicating in any number of nodes, blocks of transactions cryptographically signed to prevent their alteration, as well as to prevent the alteration of the order of the blocks within the chain. The consensus on the order of transactions and their entry into the network is given by different algorithms such as Byzantine Fault Tolerance.

  • Computational nodes managed by various entities
  • Incorruptible digital ledger of transactions shared by participant nodes
  • Stores information in a distributed and decentralized way
  • Through cryptography, it provides incorruptible records in unalterable sequence


  • - A blockchain run by a Consortium of institutions is considered as a private blockchain, where each party or institution doesn’t entirely trust each other
  • - Health care and insurance industry
  • - Authorizations associated with electronic DNI
  • - Supply chain and logistics
  • - New Paradigm of Databases
Public blockchains
  • - There are currently many public blockchains that support crypto-currencies like Bitcoin or Ethereum
  • - The information stored in the blockchain can neither be erased or changed
  • - Legal documents and certificates
Blockchain Security and Privacy
  • - There are no centralized points of vulnerability
  • - Data is not being held centrally
  • - Every participant user has a key-pair, a private and a public key, that defines its identity
  • - User to user transaction become possible, without the intervention of a central
Network of computing nodes
  • - Every blockchain consists of computing nodes that jointly manage a decentralized database of transactions
  • - Every node connected to the blockchain network validates and relays transactions
  • - Planisys provides Blockchain nodes in the form of Linux servers that run the Multichain software
Benefits of running a private blockchain
  • - 'Private' blockchain doesn’t mean exclusively internal to an organization, or completely isolated from the public
  • - The participating companies or organizations provide own validating computing nodes

Private Blockchains for Business

Central, trusted authority model

Currently, we need trusted central authorities to verify the existence of digital transactions, validate them, and keep them secure, safeguarded and private. - Our ISP tells us that our e-mail has been delivered. - Our Bank is telling us that it has effectively transferred the money we wanted to. - Our browser tells us that a website is really the site we meant to visit, and it is protected by a valid certificate.

Blockchain in bitcoin

Bitcoin participants are anonymous, everyone can join and view any past transaction, the only Asset is the shadow-currency, the only transaction is money-transfer, heavy cryptography is required for consensus … unuseful for regulated industries

CertifChain: The Exam and Certification Blockchain

The Problem(s):

Certifications, degrees, secondary school diplomas, attendance to courses and events, are very difficult to verify. Verification requires a lot of burocracy, gets worse in cross-country jurisdiction, and there are a lot of counterfeits (e.g. alledged master degrees and tampered paperwork). There is no central entity, trusted by all parties, that can assure that a certain person has achieved certain qualifications in time and space (when, where, what exactly)

The Opportunity and Our Value proposition:

Create a decentralized entity, invite all involved parties to participate, reduce burocracy and counterfeits. Let all parties participate in a decentralized system trusted by all, even when they not trust each other completely. This would be a Blockchain Consortium, where all parties can have nodes anywhere in the Internet that participate in the consensus process.
