After Japan, South Korea will also experiment with the blockchain in the elections. The National Electoral Commission and the Ministry of Science and ICT have developed new election software for computers and mobile phones based on blockchain.
The first tests in the private sector will begin in December, and the authorities will then decide whether they will deploy the system once in classical state elections.
The point of the blockchain deployment, which we know mainly from the world of cryptocurrencies, lies in data integrity. Once you save something in the blockchain database, you can never change this value again, since all other entries are mathematically related to the previous ones.
Blockchain is, therefore, resistant to fraud attempts. When a hacker attempts to change value – for example, a vote status – in the elections, the scientific integrity of the database will collapse. Conversely, when a hacker breaks into a classic SQL database and changes any of the stored values, no one needs to know at all when the design is terrible.
While classic databases require top security, blockchain is top-of-the-line in design.
That is why banks, logistics companies, etc. are also considering the use of blockchain systems. Even if cryptocurrencies disappear from the world, their decentralized database system, which records all approved transactions, may well survive.
