In my previous two articles I explored possible solutions to the IOTA donation address problem and the IOTA address alias problem . Since both solutions were written up as kind of spur-of-the-moment articles there were still a few weaknesses in the approaches, especially with respect to the alias solution.

Part 5: Consensus, confirmation confidence, and the coordinator Last week we mentioned the double-spend problem, which arises when Alice tries to spend her money more than once.

This is clearly a problem: we cannot…

I want to point out here that Tangleblog is not part of the IOTA Foundation but just a community member; the same is true for me.The IOTA Foundation did not make these emails public: As an…
