Efficient Block replication to optimize the blockchain resources

Blockchain is a great tool that provides a scalable data ledger ensuring integrity of the registered data. The validation of the blocks integrated in the blockchain can be fully distributed using a voting mechanism. This article proposes to use the blockchain as a distributed database to store information in different nodes of an ad hoc network. The main issue resides in the volume of resources needed to validate and store the blocks. We propose a distributed blockchain with k resiliency, instead of a full replication, over the nodes to reduce the overall used memory and bandwidth while providing robustness through data duplication.
