It is a traditional view that in order to increase throughput we need to increase the bandwidth. This is true but we also know that throughput can be increased by abstracting the existing bandwidth to hold more information. Increasing the blocksize will increase throughput, but is it the only way? Definitely not. The very recently improvement by Dr.Peter Wuille to segregate the witness (cryptography used to validate transactions) from the data (transactions) increases the capacity by around 66%, even if block's max size is unchanged. This is already in the testing phase. There is a whole bitcoin scaling roadmap & a lot of work going on.[0] Practically, the death scenario being painted by XT hasn't realised and transactions are still going through normally.[1] The bitcoin developer community comprises of very capable hackers many of whom are not only PHDs but have also invented new cryptographic techniques and also are robust security coders.[2][3] [0]https://bitcoin.org/en/bitcoin-core/capacity-increases-faq https://bitcoin.org/en/bitcoin-core/capacity-increases-faq [1]http://statoshi.info/dashboard/db/transactions?panelId=4&fullscreen&from=1435768112971&to=1452875394268 http://statoshi.info/dashboard/db/transactions?panelId=4&ful...
