If you would like to study blockchain, but doubt that it is worth the time, pay attention to the field of application of this technology, which is becoming more and more extensive. In addition to private projects, blockchain is seriously interested in government agencies, where transparency and controllability of information plays a very important role.
The popularization of blockchain and the rapid development of blockchain technologies lead to a permanent shortage of qualified blockchain developers to create new solutions. According to Upwork experts, the demand for blockchain specialists has grown significantly in recent years.
Created as the driving force behind the first cryptocurrency, Bitcoin, blockchain has managed to prove its usefulness in other directions as well. Distributed ledger technology can help automate administrative procedures involving the state, which require legal entries to be made in a number of registers and registers related to property rights, civil status, proof of legal capacity, and health status.
In addition to the national level, the municipal and regional ones have potential:
creation of portals for public participation of citizens in the affairs of the city - region - country;
development of a unified register that stores information about the history of placing municipal orders;
using a mechanism for transparency in the distribution of benefits and subsidies, places in children's camps, etc.The blockchain approach is promising in the field of voting and elections. Among the developments:
The Greek experience of the introduction of the electronic voting system E2E - it allows the voter to check the time and the fact of casting his vote for a specific candidate.
Conducting intraparty voting in Texas (via Blockchain Technologies Corp).
The Australians from NVB are promoting blockchain voting software as a "political application": a citizen can vote on any political issue so that politicians can get the opinion of voters and listen to it.
An Indonesian hacker organization, Protect the Voice, was founded to publicize election results, exposing an abundance of fraud. Citizens were given the option of checking and confirming the results from all polling stations.
"Voting" on the blockchain to solve current commercial problems: for example, by shareholders (NASDAQ stock exchange), as well as testing the e-proxy voting system for bondholders (RF).
Prevention of threats and hacker attacks: blockchain makes it possible to strengthen cybersecurity due to the lack of a single point of failure, immutability of the ledger.For an experienced programmer with skills in C ++, JavaScript, HTML and CSS, it will not be so difficult to understand the intricacies of working with the blockchain. And the abundance of tasks and staff shortage, which we talked about above, will allow him to forget about periods of financial instability and the absence of serious projects.
