@ittaia My FLP Lemma 3 mental model "clicked" for me when I compressed the whole system state into this form:

[3,1] - states of two nodes (any number, say, from 1 to 5)
[e,e'] - shared message queue

Better config. labels:
U - uncommitted
C - committed

Then, case 1 becomes this square

@ittaia The hardest part with FLP85 is to trust the "graph of configurations" abstraction. I compressed the whole system state to `[local states][message queue]` out of definition from the original article, and it made me mentally trust the proof like it's a real execution model

@ittaia I find these 2 AI-generated diagrams pretty useful for a basic understanding of FLP85. Wdyt?

Today in the Reth chat I dumped everything I know about >10x'ing the performance of Reth's state root, the real bottleneck in crypto performance.

This includes my understanding of how other DBs like Geth, Solana, Monad, Firewood achieve their performance & verifiability.

#Security is about doing basic things well. People tend to overcomplicate. And in reality, it's good when at least the basic #security controls are really integrated into processes or into the product.

🥰I just found the 1st dependent of the `cliclack` 🦀 crate, the app which uses `cliclack` to build its TUI: https://t.co/VehoOPcphW

#NEARProtocol node (neard) documentation is here: https://t.co/jDAd2BaSEV

@n_moore I created a Clack prompts alternative for @rustlang 🦀 - CliClack. It is here: https://t.co/BE3dj0QE6l

Fun fact: though I write about #cybersecurity basically, the most popular article on my blog is about #Qemu automation via terminal.

My fancy terminal configuration (with @StarshipPrompt 🚀) is now the most popular article on my blog: https://t.co/NYz9cgZXfC

@dfrankland_ Hello! 👋 Would you be able to transfer your abandoned crate to me: https://t.co/T404aYXa33? I have something to deploy there. Thanks!

@a_seven_life @OnMachina Sorry to hear that. From the statement I see that it were other people originally... Personally, I joined OnMachina in 2023 to build a decentralized storage: technology and engineering are on my shoulders, and we have progress.

[Alexander Fadeev @fadeevab_com]

Engineered the first live demo of @OnMachina for the #ETHDenver2023 stage.

[AVB @AvbNear]

Very impressive demo from @onmachina👌

Decentralised storage is coming to NEAR 😏

Currently on Testnet, calling for developers to join Beta Program.

#NEAR #NEARisNOW

@a_seven_life @OnMachina No, I know nothing 😕 2 years ago I wasn't even in Web3 space. Are you sure you don't confuse different companies with a similar name?

[Alexander Fadeev @fadeevab_com]

@a_seven_life @OnMachina What, why?

[Alexander Fadeev @fadeevab_com]

Seems like, many developers just put different ideas, which don't fit into strong #FT and #NFT concepts, into #SFT (Semi-FT): shares (more like FT), tickets (more like NFT), inapp purchases. Many of them have different mutually-incompatible requirements.

I have completed the #GameTheory course on Coursera. The course itself is really bad except for practical assignments. Thankfully, I found an incredible YouTube course @gametheory101 (William Spaniel).

Me, trying to absorb the Game Theory in the past few weeks:

@mitsuhiko What a gross irony :)

[Alexander Fadeev @fadeevab_com]

If you wish to understand the principles and algorithms of #decentralization, I recommend a pretty deep course about Secure Multi-Party Computation (SMPC): https://t.co/xUBBxE5pHk (e.g. there are Byzantine Agreement and Reed-Solomon error correction algorithms). By @nptelindia
