In 2014, I made a post and a presentation with a list of hard problems in math, computer science and economics that I thought were important for the cryptocurrency space (as I then called it) to be able to reach maturity. In the last five years, much has changed. But exactly how much progress on what we thought then was important has been achieved? Where have we succeeded, where have we failed, and where have we changed our minds about what is important? In this post, I’ll go through the 16 problems from 2014 one by one, and see just where we are today on each one. At the end, I’ll include my new picks for hard problems of 2019.The problems are broken down into three categories: (i) cryptographic, and hence expected to be solvable with purely mathematical techniques if they are to be solvable at all, (ii) consensus theory, largely improvements to proof of work and proof of stake, and (iii) economic, and hence having to do with creating structures involving incentives given to different participants, and often involving the application layer more than the protocol layer. We see significant progress in all categories, though some more than others.

La elección de mayo de 1989 fue la primera misión observadora del Carter Center, una oenegé estadounidense. En ese momento, una delegación liderada por el expresidente Jimmy Carter declaró la elección como fraudulenta. Un artículo publicado en el New York Times el 9 de mayo, dos días después de las elecciones, detalla las declaraciones de Carter en el programa Nightline de ABC News. “Espero que haya un llamado internacional en condena del dictador que le robó las elecciones a su propio pueblo”, habría dicho Carter. La nota dice que Carter intentó hablar con Manuel Antonio Noriega para discutir la situación, pero “no tuvo éxito”.
