How to test the network ?

You can test functionalities of the network through the test network available at this address : https://api.demo.katena.transchain.io/api/v1

What is the difference between you and your competitors ?

We developed our own blockchain network, our solution is not dependent on technical changes on which we would not have sufficient control as is the case for our competitors.

What is your validation frequency ?

Our blockchain has a validation frequency of 1000 transactions per second.

Can you also develop private blockchains ?

We believe that a robust proof, a robust certification need a public implementation with an infrastructure shared between multiple actor in an agnostic way.

What kind of consensus are you using ?

We use PTFB (pratical byzantine fault tolerance) algorithm for consensus and not a POW (Proof of Work) algorithm as the Bitcoin network.

Is your blockchain based on existing solutions such as Bitcoin, Ethereum or Hyperledger ?

We were inspired by multiple existing blockchains where we began. But for more than a year we are developing our own solution without any link to these solutions.

How can you validate data if you don't have any cryptocurrency on your network ?

Our nodes are maintained by actors and software developers that use our blockchain to deploy their applications. In counterpart, they can benefit of all the advantages of using our platform. In this win-win paradigm, no need to reward them with cryptocurrency.

How long does it take to implement your solution ?

We provide an API and a sdk to connect your application to our solution in a simple way. For further informations, please refer to this documentation : https://doc.katena.transchain.io
