Bitcoin XT, also known as BIP-101 (Bitcoin Improvement Proposal -101) has been making a gradual progress. Bitcoin XT was introduced by two Bitcoin Core developers – Gavin Andresen and Mike Hearn. It is supposed to be one of the answers to the prevailing Bitcoin block size issue.
Bitcoin XT or BIP-101 proposes the block size to be increased from the current size of 1 MB to 8 MB followed by doubling of block size every alternate year. The main reason for the proposal was to ensure that the Bitcoin network is future-proof and scalable. Currently, the smaller block size of 1 MB has a limitation when it comes to increased transactions. As the number of transactions over the blockchain increases, the processing speed has to increase proportionally to ensure that there is no delay in operations. At present, the blockchain can process only two transactions per second. If the rate of processing stays the same even after the number of transactions over the network goes up, it will create delays and backlogs. This may even result in
