What are the main challenges in scaling Blockchain networks?

The question is about Blockchain Development .

Answer:

The main challenges in expanding Blockchain networks are slow transaction speeds, network congestion, and high energy consumption. As more users join and conduct more transactions, the network becomes slower and more costly. Solutions such as sharding, layer-2 protocols (like Lightning Network), and improved consensus algorithms are available, but implementing them without compromising security or decentralisation is difficult.
