How to Enable Privacy on a Public Blockchain?

Daily Fintech

ZCashnetworkMost cryptocurrencies out there expose your entire payment history to the public, because each transaction registration on the blockchain requires validation by each node. Some scientists and developers realised this problem early and are working on adding a privacy layer on top of blockchain based currencies. Here, I’m going to talk about Zcash, a young cryptocurrency that is leading the way to provide private transactions on a public blockchain, without compromising decentralization.

Zcash, pronounced “zee-cash” was introduced in October 2016, with the aim to offer “privacy and selective transparency of transactions.” As stated on their official website, “Zcash is the first open, permissionless cryptocurrency that can fully protect the privacy of transactions using zero-knowledge cryptography.” Zcash payments do get published on a public blockchain, but they shield away the sender, recipient and amount information from other blockchain nodes. They say, “If Bitcoin is like http for money, Zcash is https—a…

Central Bank Digital Currencies: A Revolution in Banking?

Some great suggestions from Ellen Brown on how CBs can offer banking services directly using block chain technologies.

WEB OF DEBT BLOG

Several central banks, including the Bank of England, the People’s Bank of China, the Bank of Canada and the Federal Reserve, are exploring the concept of issuing their own digital currencies, using the blockchain technology developed for Bitcoin. Skeptical commentators suspect that their primary goal is to eliminate cash, setting us up for negative interest rates (we pay the bank to hold our deposits rather than the reverse).

But Ben Broadbent, Deputy Governor of the Bank of England, puts a more positive spin on it. He says Central Bank Digital Currencies could supplant the money now created by private banks through “fractional reserve” lending – and that means 97% of the circulating money supply. Rather than outlawing bank-created money, as money reformers have long urged, fractional reserve banking could be made obsolete simply by attrition, preempted by a better mousetrap.  The need for negative interest rates could also be eliminated…

By Mick Brown

So, I say to Yanis Varoufakis, you were an obscure university lecturer, with a sideline in writing comment pieces about economics, who had also devised and plotted virtual currencies for computer games, but your only experience of political office was almost 40 years ago as secretary of the Black Students Alliance at the University of Essex (even though you’re white) – how exactly did you end up for five months as one of the pivotal figures in the biggest economic crisis to engulf Europe since the Second World War?

“Guerrilla Warfare Against a Hegemonic Power”: The Challenge and Promise of Greece

If Greece were to issue a digital currency to replace the Euro; a temporary measure with many precedents – including Roosevelt in 1933.

WEB OF DEBT BLOG

Banks create money when they make loans. Greece could restore the liquidity desperately needed by its banks and its economy by nationalizing the banks and issuing digital loans backed by government guarantees to its ailing businesses. Greece could provide an inspiring model of sustainable prosperity for the world. But it is being strangled by a hegemonic power in a financial war that is being waged against us all.  

On July 4, 2015, one day before the national vote on the austerity demands of Greece’s creditors, it was rumored in the Financial Times that Greek banks were preparing to “bail in” (or confiscate) depositor funds to replace the liquidity choked off by the European Central Bank.

The response of the Syriza government, to its credit, was “no way.” As reported in Zerohedge, the government was prepared to pursue three “nuclear options” to protect the deposits of the Greek people:
