Bitcoin scalability: Why is it so difficult to increase scalability?

Bitcoin scalability means the limitation of blockchain for the processing of multiple transactions in the Bitcoin network. Bitcoin processes 7 transactions per second which is very much low as compared to the other cryptocurrencies in the market.

Bitcoin’s fundamental goal is to provide a decentralized replacement of the traditional transaction system. In order to achieve that goal, the Bitcoin network has to solve the scalability problem first.

Why increasing scalability is so difficult: 

The scalability issue is present in major crypto blockchains like ETH and BTC. With the everyday increasing popularity of the world’s largest cryptocurrency, the number of blocks to complete a transaction also increases. When the number of blocks increases, so does the average time to complete a transaction. To solve this issue, the size of an individual block would have to be increased to increase the transaction process. But the “decentralist” believe that it would make Bitcoin more centralized making miners dismantle the bigger blocks in a short period of time, compromising security and undesirable regulations.

Solutions: 

The biggest challenge today faced by existing blockchain networks like BTC ETH is scalability. Once it is solved, it would help us to build a creat a decentralized global currency that would be mass adopted and implemented all over the world. Here are some solutions that would counteract these scalability issues.

  1. Lightning Network:

The lightning network is built to make transactions cheap and fast on the Bitcoin network.  As a part of “layer 2” network technologies, it allows some transactions off of the main blockchain to make it work faster.

  1. Dynamic Block Size:

The scalability problem can also be solved using dynamic block size. These blocks can increase or decrease depending on the mining difficulty in the network.

  1. Segregated Witness

Segregated Witness or SegWit is a process in which certain parts of a transaction are removed to free up some space to validate more transactions in a block.
