@hayatu__ @illustrarch A sliding door / pocket door is the right approach. Used on trains and busses for their WC. Bifold doors used on Airplanes.

If you lived in this Dune Tower on Marco Island FLA, the wind would have charged all your storage batteries for plenty of power, and your living space would be 3m above the storm surge. Survive #HurricaneIan.

OK. So a Rollup is just a blockchain layer on top of an Ethereum network blockchain base layer. How many layers can the Ethereum layer support ?

(1/15) @ethereum Scaling Technology

State Channels → Plasma → Optimistic Rollups → ZK-Rollups

Your guide to the technologies that will scale Ethereum from 12 to 100,000 txns/sec... at a lower cost than you pay today!

[Logarithmic Rex @LogarithmicRex]

(4/15) State channels are the first attempt at moving execution off-chain.

Channels are one-time relationships between two or more parties. The parties lock up capital on-chain, allowing them to exchange IOUs for no cost.

[Logarithmic Rex @LogarithmicRex]

(6/15) Plasma (chains) were developed to address (some of) these issues.

Plasma are independent blockchains that are much higher performance (and much more centralized) than @ethereum. However, they are anchored to the World Computer by posting data back to mainnet.

[Logarithmic Rex @LogarithmicRex]

(9/15) The first category of rollups are optimistic rollups.

Optimistic rollups make the assumption that all txns that are posted to mainnet are valid and so it records them on-chain. But, just in case, they also leave open a challenge window.

[Logarithmic Rex @LogarithmicRex]

(11/15) Which brings us to the real solution to blockchain scaling and the future of @ethereum: ZK-Rollups.

Like their optimistic brothers, ZK-rollups post ALL data to mainnet, but they also provide a a zero-knowledge proof.

Like what you read? Help me spread the word by retweeting the thread (linked below).

The problem with free speech in America is that social media gives these zealot extremists a soapbox to stand and broadcast their nonsense to the world. The bigger problem is that some people actually listen !!

[No Lie with Brian Tyler Cohen @NoLieWithBTC]

Marjorie Taylor Greene just said she is introducing articles of impeachment against President Biden for investing in solar panels, because she says they will “plunge America into darkness” because she thinks they would cause the lights to turn off at night.

Here's a way to rise above sea level changes resulting from climate change:

@UmarBzv Ancient times, fire was used for cooking and heating. What if someone threw that wooden key in the fire?

[Rahbaba Kahn @RobertRahbaba]

This self-sufficient dwelling is better. Off the grid, and out of the flood zone. #architecturephotography

[designboom @designboom]

this elevated house is brillhart architecture's response to the miami coastline's harsh environmental conditions. https://t.co/UneMq9bRXi

[Rahbaba Kahn @RobertRahbaba]

@designboom Already built that. Self-sufficient tower dwelling, rising above the flood zone. Coastal habitat. #architecture #windpower #glulam
