Why Steem curation reward
is needlessly unfair and how to fix it.

This is a paper written by Alex Mizrahi on Steemit, about the unfairness of rewards in Steem curation. Alex Mizrahi proposes more fair solutions to the rewards of the users, such as rewarding them in relation with their steem power, making the distribution more proportional.

A blockchain-based property ownership recording system.

For any kind of a high-value property (real estate, cars, art) it is important to have accurate records which identify the current owner and provide a proof that he is indeed the owner. From the point of view of a computer security expert, currently people have to rely on a trusted third party. E.g. a government agency might be responsible for keeping track of ownership information. Sometimes, these records are not preserved in a systematic way. Is it possible to keep track of property ownership through some kind of a distributed system which won't rely on trust? What would it require? This paper shows our idea of using colored-coins for this purpose.

Cryptocurrencies without Proof of Work.

This is a paper by Iddo Bentov, Ariel Gabizon at the Computer Science Department of Technion University, and Alex Mizrahi. The authors examine pure Proof of Stake protocols for decentralized cryptocurrencies in which the participants do not need to deplete physical scarce resources. This work includes both a critique of existing cryptocurrency protocols of the PPC/NXT kind, as well as an analysis of novel pure Proof of Stake protocols that seek to mitigate the problems that the existing protocols suffer from.

Proof of Activity: Extending Bitcoin's Proof of Work via Proof of Stake.

This is a paper written by Iddo Bentov, together with Litecoin founder Charlie Lee, Alex Mizrahi, and Meni Rosenfeld, chairman of the Israeli Bitcoin Association. The authors analyse a hybrid between Proof of Work and Proof of Stake as a remedy against possible future attacks on Bitcoin.
