Newcomers to #crypto generally face one big problem — since we use a lot of jargon, many fundamental concepts are hard to understand.

I'm going to attempt to simplify things with plain English explanations for many crypto concepts.

Let's start with: #Wallets

🧵/1

Blockchain data can be freely read by anybody with the right tool, usually a web app written by a developer.

But in order to make a change to blockchain data such as sending funds to someone or minting an NFT, you need to send a "transaction" to the blockchain.

🧵/2
A "transaction" (Tx) is an action that changes blockchain data. It has four primary components:

1⃣ What the Tx will do? (ex: transfer funds)
2⃣ Information needed for the Tx? (ex: amount, recipient)
3⃣ Tx fees (aka "gas")
4⃣ Authorization for the Tx via a digital signature

🧵/3
A digital signature here isn't just your scribbled signature in picture form. It specifically means using cryptographic techniques to create a sealed digital envelope that mathematically proves that "you" approved the Tx.

The "you" in this case is not you, the person.

🧵/4
"You" really means someone or something in possession of a special piece of information called a "private key"

The private key is a secret piece of information associated with your blockchain account that is used by a special tool to digitally sign the sealed Tx envelope.

🧵/5
The commonly used name for the special tool that is used to sign the sealed Tx envelope is...

🎉 Wallet 🎉

In a nutshell, a crypto Wallet is a tool used to manage a list of accounts and their private keys that are necessary to sign blockchain transactions.

🧵/6
You're probably thinking, "But wait, Nik. That doesn't sound right. My crypto Wallet contains my BTC, ETH, NFTs, Doge 😜. Your definition of Wallet doesn't mention how my crypto is stored in it. What gives?"

That friends, is the biggest misconception about crypto Wallets.

🧵/7
Repeat after me — crypto Wallets do NOT contain any crypto assets. No coins. No tokens. No NFTs.

Crypto Wallets are a tool to manage your accounts and private keys — that's it.

Your crypto assets are ALWAYS data entries on the blockchain ledger, not in your crypto Wallet

🧵/8
This means you can use any number and type of crypto Wallets to transact for an account whose private key you know, and it will work swimmingly.

Your cryptocurrency — not in your Wallet
Your tokens — not in your Wallet
Your NFTs — not in your Wallet

So where are they?

🧵/9
Your crypto assets are actually just blockchain data:

Coins you own — an entry for your account in the ledger of the blockchain on which that Coin is a native cryptocurrency

Tokens and NFTs you own — an entry for your account in the Smart Contract that issued the token

🧵/10
Summary:

A crypto Wallet is a tool used to manage blockchain accounts and associated private keys.

Crypto assets are never in a Wallet, they always remain on the blockchain.

You can use multiple Wallets for the same account — just the UI will be different not the data.

#தினம்_ஒரு_திருவாசகம்
தொல்லை இரும்பிறவிச் சூழும் தளை நீக்கி
அல்லல் அறுத்து ஆனந்தம் ஆக்கியதே – எல்லை
மருவா நெறியளிக்கும் வாதவூர் எங்கோன்
திருவாசகம் என்னும் தேன்

பொருள்:
1.எப்போது ஆரம்பித்தது என அறியப்படமுடியாத தொலை காலமாக (தொல்லை)

2. இருந்து வரும் (இரும்)


3.பிறவிப் பயணத்திலே ஆழ்த்துகின்ற (பிறவி சூழும்)

4.அறியாமையாகிய இடரை (தளை)

5.அகற்றி (நீக்கி),

6.அதன் விளைவால் சுகதுக்கமெனும் துயரங்கள் விலக (அல்லல் அறுத்து),

7.முழுநிறைவாய்த் தன்னுளே இறைவனை உணர்த்துவதே (ஆனந்த மாக்கியதே),

8.பிறந்து இறக்கும் காலவெளிகளில் (எல்லை)

9.பிணைக்காமல் (மருவா)

10.காக்கும் மெய்யறிவினைத் தருகின்ற (நெறியளிக்கும்),

11.என் தலைவனான மாணிக்க வாசகரின் (வாதவூரெங்கோன்)

12.திருவாசகம் எனும் தேன் (திருவா சகமென்னுந் தேன்)

முதல்வரி: பிறவி என்பது முன்வினை விதையால் முளைப்பதோர் பெருமரம். அந்த ‘முன்வினை’ எங்கு ஆரம்பித்தது எனச் சொல்ல இயலாது. ஆனால் ‘அறியாமை’ ஒன்றே ஆசைக்கும்,, அச்சத்துக்கும் காரணம் என்பதால், அவையே வினைகளை விளைவிப்பன என்பதால், தொடர்ந்து வரும் பிறவிகளுக்கு, ‘அறியாமையே’ காரணம்

அறியாமைக்கு ஆரம்பம் கிடையாது. நமக்கு ஒரு பொருளைப் பற்றிய அறிவு எப்போதிருந்து இல்லை? அதைச் சொல்ல முடியாது. அதனாலேதான் முதலடியில், ஆரம்பமில்லாத அஞ்ஞானத்தை பிறவிகளுக்குக் காரணமாகச் சொல்லியது. ஆனால் அறியாமை, அறிவின் எழுச்சியால், அப்போதே முடிந்து விடும்.
How can we use language supervision to learn better visual representations for robotics?

Introducing Voltron: Language-Driven Representation Learning for Robotics!

Paper: https://t.co/gIsRPtSjKz
Models: https://t.co/NOB3cpATYG
Evaluation: https://t.co/aOzQu95J8z

🧵👇(1 / 12)


Videos of humans performing everyday tasks (Something-Something-v2, Ego4D) offer a rich and diverse resource for learning representations for robotic manipulation.

Yet, an underused part of these datasets are the rich, natural language annotations accompanying each video. (2/12)

The Voltron framework offers a simple way to use language supervision to shape representation learning, building off of prior work in representations for robotics like MVP (
https://t.co/Pb0mk9hb4i) and R3M (https://t.co/o2Fkc3fP0e).

The secret is *balance* (3/12)

Starting with a masked autoencoder over frames from these video clips, make a choice:

1) Condition on language and improve our ability to reconstruct the scene.

2) Generate language given the visual representation and improve our ability to describe what's happening. (4/12)

By trading off *conditioning* and *generation* we show that we can learn 1) better representations than prior methods, and 2) explicitly shape the balance of low and high-level features captured.

Why is the ability to shape this balance important? (5/12)

A THREAD ON @SarangSood

Decoded his way of analysis/logics for everyone to easily understand.

Have covered:
1. Analysis of volatility, how to foresee/signs.
2. Workbook
3. When to sell options
4. Diff category of days
5. How movement of option prices tell us what will happen

1. Keeps following volatility super closely.

Makes 7-8 different strategies to give him a sense of what's going on.

Whichever gives highest profit he trades in.


2. Theta falls when market moves.
Falls where market is headed towards not on our original position.


3. If you're an options seller then sell only when volatility is dropping, there is a high probability of you making the right trade and getting profit as a result

He believes in a market operator, if market mover sells volatility Sarang Sir joins him.


4. Theta decay vs Fall in vega

Sell when Vega is falling rather than for theta decay. You won't be trapped and higher probability of making profit.
