Blockchain Data Exchange System – Upwork

Our goal is to create a prototype solution that allows to securely exchange information between participants.

Here are requirements:
– Using public or private blockchains
– Data can be submitted to blockchain by any participating node
– Data can be requested by all nodes or by a specific node only

We need to create a back-office with 2 users that share and exchange sensitive information with each other or with all nodes.

Preferably, this solution should be based on a public and secure blockchain. Alternatively, it can be based on a private blockchain.

Hourly Range: $10.00-$40.00
