As we all probably know, blockchain is not perfect and it has some drawbacks. Let’s take a closer look at some of the major blockchain drawbacks.
From an
economic point of view, blockchain has certain disadvantages.
🔹 High volatility of the most widespread blockchain with the PoW consensus algorithm due to the complexity of the transaction - makes it an expensive technology.
🔹 When transferring electronic values, the blockchain allows you to significantly save on payment for the services of intermediaries and guarantors. However, the very creation of the system and its implementation in any area is very costly.
🔹 Scalability is another limitation due to the size of the public blockchain. If the database is overloaded, the speed of transfers is significantly reduced. For instance,
in the bitcoin system, one transaction can take 4-5 hours or more.
🔹 Differentiation of the blockchain. There are currently over 1,400 digital coins in existence, many of which have their own versions of the blockchain. It is not yet clear which of them will be able to survive and which will disappear.
Among the
technical shortcomings, the following can be highlighted:
🔹 Impacts at the network level:
- DDoS hacker attack, or a distributed denial of service attack;
- "attack of the Sibyl";
- Eclipse attack, or "information eclipse attack."
🔹 Actions at the user level:
botnets are special anonymous malicious programs that disguise themselves as pirated versions of licensed programs.
🔹 Impacts on blockchain integrity:
- "Attack 51%";
- Double spending, which implies twice successful use of the same funds;
- Selfish mining. This phenomenon can kill the concept of a decentralized system.
🔹 Other attacks:
- Phishing.
- Deface - address substitution.
