I previously wrote a post on proof of work (PoW) and mining . The first half generated great interest but (apparently) failed to be universally persuasive. For example, CCRG (Ethereum’s multi-million dollar funded “research” organization) consists almost entirely of academics theorizing about proof of stake (PoS) .

An introduction to Bitcoin without the jargon: Bookkeepers, Ledgers and Anonymity.
Cryptanalyst Marc Stevens from the Centrum Wiskunde & Informatica (CWI) in Amsterdam, known for breaking the https security in 2008 using a cryptanalytic attack on MD5, analyzed the recent Flame virus this week.
Web3 security lessons from the Resolv hack: how a compromised key enabled a $23M exploit, what went wrong, and how DeFi protocols can prevent similar attacks.
How do you encrypt a file such that it can be decrypted after a date, but not before? Use serial computations for proof-of-work using successive squaring, chained hashes, or witness encryption on blockchains.

In his 2008 white paper that first proposed bitcoin, the anonymous Satoshi Nakamoto concluded with: “We have proposed a system for electronic transactions without relying on trust.” He was referring to blockchain, the system behind bitcoin cryptocurrency. The circumvention of trust is a great promise, but it’s just…
Control over important internet services has shifted from open source to proprietary services operated by big tech. As a result, people got access to technology, but that shift also created serious problems.
The majority of the EU Parliament's lead committees today approved far-reaching new anti-money laundering laws: Anonymous cash payments over €3,000 will be banned in commercial transactions. Cash payments over €10,000 will even be completely banned in business transactions. And anonymous payments in

The responses of many to my post on Bitcoin reveal a powerful tendency to underestimate the ill-effects of deflation on a social economy. This tendency to underestimate deflation’s deleterious impact matters beyond debates on Bitcoin per se. For example, in Europe the incapacity of the European Central Bank (ECB) to…
