The Maps in Ghana with the technology Blockchain

Blockchain: revolution for land registration in Ghana

A simple address, a title?

Not so evident in Africa, where 90% of rural areas are not listed.

To solve the problems associated with the lack of registers and land registers, the African NGO Bitland blockchain uses technology designed to use the Bitcoin currency, transaction and information security.

Technology Extension in the rest of Africa?
This digital innovation creates a transparent, tamper-proof property register. Individuals can benefit from state services.

For its part the state meanwhile can for example collect taxes.
Currently, blockchain is a phenomenon at the forefront of innovation; start ups creations multiply on the subject, the oldest articles on the technology have no more than a year, and investors already mobilized huge sums to make sure not to miss the checkmark.

The blockchain is approached as a major innovation, and many predictions even argue that it will change our lifestyles in the same way as the Internet or printing.

This is why it is so important to stay informed on the subject, and especially in France, where public opinion is still poorly informed about it.

Locate the Blockchain

In 2009 has created a digital currency Bitcoin.

This currency was based on a technology that certified that Bitcoins could not be duplicated, and therefore assured that this money would not be falsifiable: this technology is called the blockchain.

The concept ? Each Bitcoin is “traceable” from its inception through files of detainees and updated by each user of the currency. Everyone can tell when such Bitcoin has passed through such account, which means that creating fake Bitcoin is impossible without it sees on the “chain” of transactions.

Where the revolution begins is when the developers had the idea to use this system for other than the currency Bitcoin.

A revolution that can affect all aspects of life

The blockchain is a storage technology and information transmission, transparent, secure, and operating without central control body. By extension, a blockchain is a public database, secure and distributed (that is to say shared by different users, without intermediaries). This blockchain ( “block chain”) contains all of the exchanges between users since its creation, exchange each can verify the validity (that is to say from his computer to check if the system is good or if someone one tried to drag a “false”).

A blockchain can be likened to a large public accounting book, and unfalsifiable anonymous. As written by the mathematician Jean-Paul Delahaye, one must imagine “a great book, everyone can play freely and without charge, on which everyone can write, but that is impossible to erase and indestructible. ”

This technology can be useful in many other areas as currency: patents, votes for election, financial instruments (derivatives, loans, micro-credit …), real estate, certificates of all kinds (eg degrees), health data, games, bookings (hotels, restaurants …), our keys (home, car …) … the operating fields are immense.

Generally, the blockchain can potentially replace all the “trusted third party” centralized (banks, notaries, land registry …) by a decentralized computer system.
