“As we conclude our “Discovering Bitcoin” series, we will build on the use of digital signatures and of the CoinJoin paradigm to explore concepts of unique chronology, mining fees and off-chain transactions.” – Giacomo Zucco

“In Part 6 of this “Discovering Bitcoin” series, we will build on the idea of using digital puzzles as a way to reproduce scarcity, and on the importance of a supply-control mechanism to grant some hardness to digital money, to explore concepts of proving ownership through signatures and scripts, and the technique known as CoinJoin.” – Giacomo Zucco

Continuing the excellent series of Discovering Bitcoin, moving into the digital age, we have lost the most fundamental element of our money, it’s “hardness.” By what means can we get it back? Can we make a scarce money in the digital world, that has no authority, no ruler? Can we restore the freedom of decentralized money? Find out about the brilliant use of difficult puzzles, to achieve digital hardness, in part #5 of Giacomo’s excellent series, “Digital Scarcity.”

“While it was pretty difficult for him to take over the very decentralized process of people exchanging gold nuggets, there are now a few big, public, trusted, vulnerable entities he can easily seize control of.” – Giacomo Zucco

“it clearly involves moral, political and ethical aspects, like the importance of privacy as a human right. I will use the term “darkness” to address this attribute.” – Giacomo Zucco

“In order to be useful for this kind of process, a good must possess a good “hardness”: Any unit of said good should not significantly lose its ability to provide utility if stored over some period of time.” – Giacomo Zucco
