Today is not a good news day for Ethereum. A vulnerability found within a popular wallet has frozen potentially hundreds of millions of dollars of the crypto currency in a second setback in recent months. Parity Technologies, the company behind widely used wallet service Parity, today disclosed an issue that could enable the contents of a wallet to be wiped. The issue affects multi-sig wallets — a technology that uses the consent of multiple parties for additional security on transactions — that were deployed after July 20. In other words, ICOs that were held since then may be impacted. It’s a […]

In cryptocurrency circles, calling something “centralized” is an insult. The epithet stems from Bitcoin creator Satoshi Nakamoto’s revelation: a monetary system doesn’t need a central authority, like a government, to work. That’s such a potent idea that it’s morphed into a battle among crypto-enthusiasts between good—that is, “decentralized”— currencies and evil ones, or anything with a whiff of “centralization,” that are assumed to threaten the utopian view of cryptocurrencies as the vehicle for a new financial world order. Do these arguments hold any water? Emin Gün Sirer, a cryptocurrency expert at Cornell University, says in many cases the jury’s still […]
The Canadian government has launched a trial to explore the use of technology in making government research grant and funding information more transparent to the public. For the trial, the National Research Council (NRC) is using the Catena Blockchain Suite, a Canadian-made product built on the Ethereum blockchain, to publish funding and grant information in real time. When the NRC creates or amends a grant, the pertinent information is stored on the Ethereum blockchain, and posted on an online database that Canadians can peruse.

They analyzed the attack and realized that there was no way to reverse the thefts, yet many […]

Now, major bitcoin and cryptocurrency exchange Coinbase has teamed up with global payments processor Visa to try […]
