An Ethereum-based Ponzi scheme called Fomo3d is going viral

By Leo Zhang

It was only a matter of time before Ethereum, the home of the ICO and token-gambling, gave birth to literal casino games:

"Fomo3d is simple in concept. You buy a 'key,' which is kind of like a token, and that key adds 30 seconds to a timer. Part of the ETH you paid for the key goes to a pot, which currently has some 28,000 eth ($13 million). Part of it goes in 'dividends' to those that bought a key before you."

Lightning Network installation guides, philosophy and technical articles
(Coinmonks, by Gaurav Agrawal)

"The Lightning Network is one of the first implementations of a multi-party Smart Contract (programmable money) using bitcoin’s built-in scripting. The Lightning Network is leading technological development in multiparty financial computations with bitcoin. It’ll enable instant payments even for small transactions and will improve Bitcoin’s Scalability and hence will help in bitcoin adoption."

The state of hashing algorithms- the why, the how, and the future
(zkCapital, by Raul Jordan)

"Benartzi said: 'What we learned from this experience is there’s so much chaos that happens after an incident like this, where if all the parties were better coordinated, if there was a hotline, if we could share information more transparently, if we could be quicker about getting flagged accounts or flagged wallets to the exchanges so they could track those as well then we could all be better off.'"

Venmo's terrible idea
(ars Technica, by Cyrus Farivar)

"Why would I want the world, even my Internet friends, to know when I settle bar bills? I know of no mainstream payment system that makes its transactions public. PayPal, Venmo’s parent company, doesn’t even do this. After new scrutiny last week, Venmo still will not explain fully why the public default is useful."
