Because identity could not be solved with partial blockchain, same mistake Akasha is doing.&lt;p&gt;An identity is a proxy for past work done, which the identifier further wishes to use as a proxy for future working. A blockchain bypasses this by directly asking a proof of current work, irrelevant of past work done.&lt;p&gt;When a system does not use an exclusive blockchain, the identity is unable to proxy itself through PoW. Spam rules zapchain now.&lt;p&gt;To make this work they need a PoW Akashacoin.</text><parent_chain></parent_chain></comment><story><title>Akasha: A Social Media Network Powered by Ethereum and IPFS</title><url>http://akasha.world/</url></story>
