The innovative Proof of Location (PoF) system, or location confirmation, is another way to use Blockchain technology in the modern world.

GPS is a satellite navigation system covering the entire globe. Its operation is based on measuring the time of reaching a radio signal from satellites to the receiver.

Although this system has been in use for a long time and many users have already become accustomed to it, it is not without flaws. First of all, there is no protection against hacker attacks, it is not accurate enough, and it is not immune to jamming. Devices working in this system consume their batteries significantly.

Developing technology blockchain used in the navigation system may in the future change the comfort of using such devices and introduce new possibilities. No longer GPS, and kryptokartografia it can become the future.

Blockchain can create maps created and managed by users, as well as various spatial development plans and administrative divisions.

Proof of Location (PoF)

It is delivered by the company FOAM and is based on measuring the time it takes to transmit a signal between the user PoFand each of the four receivers that make up the zone.

Today, many applications can be found for this system. PoF it is helpful, for example, at monitoring the road, which they overcome our shipments before they reach their destination, and also when confirming our address, if only on the basis of the time we spend in a given place.

PoF is an autonomous and fully transparent system. It offers mapping and users can also create POI lists. These lists can be evaluated and popularized by users.

Users assess areas on the scale of attractiveness taking into account the atmosphere, crime rate or infrastructure.

However, critics believe that PoF system it is not sufficiently widespread, as well as that most of its users are men, which may result in the lack of lists of attractive places for women, and that these places may be underestimated.

Other possibilities of using this system are as fast as possible to notify the insurance company in the event of a breakdown in the flat or car collision. Then the photo is sent along with the confirmation of the location.

In the future, more and more companies and institutions will use the blockchain system, so there are also opportunities to use it in this field.
