Secure, private industry ledgers establish a single immutable record, or single version of the digital truth, that once entered, cannot be modified.

Bluetooth is a very popular choice for indoor positioning systems because of the following advantages:
- wide availability (you can find it in almost all modern chips and smart devices);

- simple implementation (the technology is easy to work with).
