Transactional scaling refers to the ability of a blockchain to handle an increasing number of transactions efficiently without sacrificing speed or performance. As user adoption grows, networks often struggle to process transactions quickly, leading to delays and higher fees.There are various methods to achieve scaling. One common approach is increasing block size, which allows more transactions to be included in each block. Another method is implementing layer two solutions, such as payment channels, which conduct transactions off the main blockchain and later settle them in batches.Improving the consensus mechanism also plays a crucial role. Switching from proof-of-work to proof-of-stake, for example, can enhance transaction speed and reduce energy consumption.Ultimately, effective transactional scaling ensures that a blockchain can support a larger user base while maintaining fast transaction times and low costs, critical for real-world application and usability.
