EthHub Weekly #119

Curated by Anthony Sassano (@sassal0x) and Eric Conner (@econoar)

👨‍🌾 Farming All the Yield

Well, that was an absolutely crazy week in Ethereum, wasn’t it? If you’ve somehow missed it, the concept of “yield farming” entered the mainstream crypto lexicon this week with the launch of Compound’s liquidity mining program and the Synthetix/Curve yield farming partnership. Eric and I will be diving very deep into this new trend on this weeks recap podcast – be sure to subscribe so that you don’t miss it!

Gitcoin Grants Round 6 is now live! You can now have your donation matched by up to 100’s of times during this matching round. If you’d like to support EthHub, you can do so here (or fund the Ethereum “state media” here). You can also support my efforts with The Daily Gwei here.

Lastly, a Chinese version of EthHub is now available – a big thanks to ECN for making this possible!

Have a great week everyone!

News of the Week

😅 Trump Told Treasury Secretary to ‘Go After’ Bitcoin, Bolton Book Reportedly Claims

President Donald Trump ordered Treasury Secretary Steve Mnuchin to focus on a clampdown on Bitcoin over negotiating a trade with China, former national security adviser John Bolton reportedly claims.

In a terse exchange about imposing sanctions and tariffs with China, Trump reportedly told Mnuchin: “Don’t be a trade negotiator,” ordering him instead to: “Go after bitcoin [for fraud].”

“If you don’t want me on trade, fine, your economic team will execute whatever you want,” Mnuchin retorted. The exchange comes from an excerpt from Bolton’s new book, obtained by the Washington Examiner.

The conversation is said to have happened in May 2018, around the time investors were cheering bitcoin on after it rose 33% against the dollar. It’s unclear from the excerpt what specifically led Trump to order Mnuchin to crack down on bitcoin and whether the two men had been talking about cryptocurrencies beforehand.

☮️ Ethereum Foundation Makes Second Crypto Donation to UNICEF

The Ethereum Foundation followed up on its 2019 gift to the United Nations Children’s Fund (UNICEF) this week with a second cryptocurrency donation. 

UNICEF crypto portfolio manager Cecilia Chapiro said the fund is now accepting applications from startups in emerging markets to receive investments via this second donation of roughly 1,125 ETH.

“We are still looking for big donors … also from a technical expertise perspective, we’re always matching our startups with mentors in the space,” said UNICEF blockchain lead Christina Lomazzo. “We’ve not received any more bitcoin, beyond what we got from the Ethereum Foundation [in 2019].” 

There’s no set number, but Chapiro expects to find five to 10 attractive startups for equity-free investments worth $100,000 each. The fund is in talks with other prospective donors, but so far none that could be named for this article.
