…wait – what happened? I thought this was a meetup?

Super Typhoon Noru!

We were not able to meet in person this week because Super Typhoon Noru had been approaching for a few days and Danang city authorities told everyone to stay inside. Noru originated over the Philippine Sea last week, and had 10-minute wind speeds of up to 175 kph (110 mph). As Noru passed over Luzon island, Philippines, widespread damage was caused. Today it passed directly over Danang, but fortunately wind speeds had reduced to 133 kph. When I went out earlier today the streets were full of leaves, branches, and some fallen trees, however I did not see extensive damage to buildings and perhaps the damage here in Danang is lower than expected, time will tell.

For more information, see Wikipedia article:

And also VN Express news, here is one relevant article:

And on to the crypto news!

Optimism Quests

Optimism and Arbitrum are the top two Optimistic Rollups (Layer 2s) on Ethereum. Arbitrum released their Odyssey earlier in the year, however it overloaded Arbitrum network and they had to pause it until Arbitrum Nitro was launched. (Arbitrum – wen restart Odyssey?!)

Optimism have a robust response to the Arbitrum Odyssey, which is Optimism Quests. This allows anyone to get 18 NFTs for using 18 different apps on Optimism. Some good reasons to do this:

• Optimism is great! Faster and cheaper than Ethereum mainnet, but with assets secured by Ethereum mainnet security

• Who doesn’t love a free NFT mint?

• Practice your Defi skills

• Understand the Optimism ecosystem better by participating in it

• Potential airdrops for using both Optimism and the apps on Optimism (caution – recommend only doing quests and minting NFTs on 1 account, to avoid being labelled as a Sybil attacker)

• Potential other future benefits of holding these NFTs

Ultrasound Money

When bridging to Optimism, find a time when Ethereum mainnet gas fees are low! Use Ultrasound Money to identify how low gas fees might go, in Metamask there is an Advanced fee option to set lower gwei and catch those dips:

Ultrasound Money is such a great dashboard, it replicates the Base Fee graph of Watch The Burn dot Com (now defunct), but also has a lot of other useful information there. I hope to go into this in more depth in future!

EF Devcon 7

Loi Luu has proposed Nha Trang, Vietnam, to host EF Devcon 7:

Here is the forum discussion:

Here in Danang we are very keen to see more conferences held in Vietnam, so we wish the Nha Trang application well!

Draper Heroes NFTs

Draper Entrepreneur Network (DEN) have been very supportive of Defi Study Group by hosting us for 18 weeks. Draper are minting NFTs now with cool artwork and optional utility! Check out these Draper Hero NFTs here:

And that’s it for this week! Hope to be back to meeting in person next week.
