Behind the conflict is an ideological split about bitcoin’s rightful identity. The community has bitterly argued whether the cryptocurrency should evolve to appeal to mainstream corporations and become more attractive to traditional capital, or fortify its position as a libertarian beacon; whether it should act more as an asset like gold, or as a payment system. The seeds of the debate were planted years ago: To protect from cyber attacks, bitcoin by design caps the amount of information on its network, called the blockchain. That puts a ceiling on how many transactions it can process -- the so-called block size limit -- just as the currency’s growing popularity is boosting activity. As a result, transaction times and processing fees have soared to record levels this year.
