According to recent news from Thailand, NECTEC of Thailand has started an electronic voting system that revolves around blockchain technology. This is an administrative organization that works under the Ministry of Science and Technology and Technological Development and the National Science Agency. NECTEC is typically the support of telecommunications, IT, electronics and IT.
Blockchain technology is becoming famous in many countries around the world for the organization of a secure and protected electoral procedure. Previously, in the United States, the State of West Virginia showed an electoral electoral procedure through a mobile blockchain voting system for the Virginians sent abroad, helping the equipped facilities. The elections held in West Virginia were extremely popular and received many optimistic responses. Many different countries like Japan and Switzerland have also voted blockchain in many elections. The intake of Bitcoin as a method to change the voting technique was measured at the time of the first days of the new technology. At a time when the virtual currency was around $ 30 (now around $ 3,500), in 2012, computer scientists in Canada were trying to exploit Bitcoin's capabilities as "a form of & # 39; carbon dating & # 39, for digital information and approximately this will make electronic voting safer.

Traditional databases are managed by a single organization and this organization has complete control of the database, including the ability to tamper with the stored data, to censor changes otherwise valid to the data or to add data fraudulently. For most of the use cases, this is not a problem because the organization that manages the database does it to its advantage, and therefore has no reason to fake the database content; however, there are other cases of use, such as a financial network, where the stored data is too sensitive and the reason for manipulating it is too tempting to allow any organization to have total control over the database. Even if we could ensure that the responsible organization never made a fraudulent change to the database (a hypothesis that, for many people, is too much to ask), there is still the possibility that a hacker may intrude and manipulate the database for its own purposes.
Blockchains in action
The most obvious example of the blockchain technology in use today is Bitcoin. Bitcoin is a digital currency system that uses a blockchain to keep track of currency ownership. Whenever someone wants to spend their bitcoins, he creates a transaction where he claims to send a certain number of bitcoins to someone else. Then they digitally sign this transaction to authorize it and transmit it to all the nodes of the Bitcoin network. When the next node creates a block, it will check that the new transaction is valid and include it in the new block, which is then propagated to all other nodes in the network, which regulate their databases to deduce the bitcoins transferred from the sender and credit them to the recipient.
