Reasons for buying

1. Nice narrative, AI concept, aiming to become the biggest AI proxy product, has locked in some key chips

2. Low market cap, new launch peaked at 285k, dipped down to 160k so I decided to scoop some, chip structure looks solid, has a few leading indicators

3. Community is tight-knit, almost 400 holders, over 200 in the community, mainly promoting through sharing images and text

Cryptography in Blockchain: The Locks, Keys, and Signatures That Secure Everything

Without cryptography, anyone could steal your crypto or fake a transaction. With it, mathematics does the job that banks and lawyers traditionally handle.

1. The Three Core Jobs of Cryptography

Job Crypto Tool What It Does Real-Life Analogy
Prove it's YOU Digital Signatures Verifies you authorized the transaction Your handwritten signature on a check
Keep it secret Public/Private Keys Ensures only you can spend your funds Your house key + your mailbox address
Lock blocks together Hash Functions Makes data tamper-proof A wax seal that breaks if opened

2. How It Works: Sending $BITCOIN to a Friend

Let's walk through sending 0.5 BTC to Sara:

Step 1: Your Two Keys

Every wallet comes with a pair:

· Public Key = Your wallet address (like your email) — anyone can send to it
· Private Key = A secret 64-character code (like your $ATM PIN) — only you should ever know it

Step 2: Creating a Digital Signature

You craft the transaction: "Send 0.5 $BTC to Sara"
Then you use your Private Key to "sign" it. This generates a unique cryptographic signature that mathematically proves: "Only the person holding this private key could have created this signature."

The network nodes verify the signature using your Public Key.

· Matches? ✅ Valid transaction
· Doesn't match? ❌ Rejected instantly

Important: Your private key is never revealed during this process.

Step 3: Hashing for Immutability

Once confirmed, your transaction is bundled into a "block."
That block gets hashed — turned into a unique digital fingerprint.
This hash is then embedded into the next block.

Here's the magic: Change even one letter in the original transaction, and the hash changes completely — breaking the entire chain. This makes historical data impossible to alter without detection.
