Blockchains and network effects

An insight that is important in relation to recent talks about hard forks: Blockchain creates a shared view of one history (or reality) among the participants who enforce the same set of rules. Also, with the recent talks about scammy ICOs and whitepaper-backed shitcoins, remember Metcalfe’s and Reed’s laws (the value of network is either […]

Ethereum and other altcoins

As you all probably know I am a fan of Bitcoin, but I am not that much of an alt-coin guy. What I mean by that is that I think that a main property of money is that it is universal means of exchange. It is good that you can store your wealth as savings […]
