Paisay bhejna
Stablecoins (dollar se juray digital sikke) minton mein duniya bhar mein ja sakte hain, kam fees ke saath.
Pakistan: Bahar se aane wali remittance ke liye bara mauqa, lekin sirf licensed platforms ke zariye.
Aaj tumhari photos, videos aur followers kisi company ke server par hain. Web3 ek naya tareeqa hai jahan data aur cheezon ki milkiyat ek company ke bajaye sab ke beech bati hoti hai.
Is sabaq mein: Web3 kya hai → kaise kaam karta hai → kahan kaam aata hai → aage kya scope hai.
Websites akhbaar ki tarah thin. Tum sirf parh sakte thay, kuch likh nahi sakte thay.
Facebook, YouTube, TikTok. Tum post karte ho, lekin data aur account company ka hai. Woh chahe to band kar de.
Koi ek malik nahi. Hazaron computer mil kar record rakhte hain, aur tumhari cheez sirf tumhari chabi se khulti hai.
Dono buttons daba kar dekho kya hota hai jab koi computer band ho jaye.
Sab log ek hi server se jure hain.
Har computer ke paas poore record ki copy hai.
Socho mohalle ki committee ka register ek bande ke paas nahi, har ghar ke paas hai. Har safha (block) pichle safhe ki "fingerprint" (hash) yaad rakhta hai. Koi ek safha badle to us ki fingerprint badal jati hai aur agla safha fauran pakar leta hai.
Try karo: Block 2 mein "Ali ne 5000 diye" ko "Ali ne 50000 diye" kar do.
Smart contract ek program hai jo blockchain par chalta hai. Shart puri ho to kaam khud ho jata hai. Na dukandaar chahiye, na beech ka banda.
>= ka matlab: 50 ya us se zyada. Yaani Rs 50, 60 ya 70, sab par juice milega.
Juice ki qeemat Rs 50 hai. Sikke dalo aur dekho contract khud faisla kaise karta hai.
Har jagah ek hi masla hai: bharosa. Web3 woh jagah kaam aata hai jahan logon ko kisi ek bande par bharosa karna mushkil ho.
Stablecoins (dollar se juray digital sikke) minton mein duniya bhar mein ja sakte hain, kam fees ke saath.
Pakistan: Bahar se aane wali remittance ke liye bara mauqa, lekin sirf licensed platforms ke zariye.
Fard aur registry blockchain par ho to koi chupke se naam nahi badal sakta. Jaali kaghzaat ka masla kam ho sakta hai.
Pakistan: Zameen ke jhagre courts mein saalon chalte hain, yahan bara faida ho sakta hai.
University certificate blockchain par jaari kare to company ek click mein dekh le ke degree asli hai.
Pakistan: Jaali degrees ka masla seedha hal hota hai.
Dawai ya aam ka har safar record ho: kis khet se aaya, kis godam se guzra. Customer QR scan kar ke dekh le.
Pakistan: Nakli dawaiyon aur export mein milawat ke khilaf madadgar.
Game ka item, art ya ticket asal mein tumhara ho, aur tum usay bech ya kisi aur game mein le ja sako.
Sabaq: Is shobay mein hype bohat hua, bohat se projects band bhi hue.
Group ka paisa aur faisle ek smart contract chalaye. Har member vote kare, aur sab ko nazar aaye ke paisa kahan gaya.
Misaal: Class ka fund, jis ka hisaab koi chupa na sake.
Pakistan ne PVARA (Virtual Assets Regulatory Authority) banayi.
Parliament ne Virtual Assets Act 2026 pass kiya. Ab crypto companies ko license lena zaroori hai, aur bina license kaam karne par 5 saal tak qaid ho sakti hai. Shariah committee bhi nigrani karegi.
Bare bank aur companies (Visa, Mastercard, Stripe) stablecoins par kaam kar rahi hain. Ghar, sona aur bonds ko token banana ("tokenization") tez ho raha hai.
Token bane assets ki value $2 trillion se $30 trillion tak ho sakti hai. Itna bara farq is liye hai ke koi pakka nahi jaanta.
Web3 shayad "crypto" naam se kam aur chupchap kaam karne wali technology ki tarah zyada aayega, jaise bijli: istemal sab karenge, naam koi nahi lega.
Blockchain par chalne wale programs likhna (zyada tar Solidity zubaan mein).
Contracts mein ghaltiyan dhoondna taake chori na ho. Is ki demand sab se tez barh rahi hai.
Aisi website banana jo wallet se jure. Is ke liye JavaScript aur React aani chahiye.
Har kaam coding nahi. Logon ko samjhana, designs aur community chalana bhi jobs hain, aur zyada tar remote hain.
Agla sabaq: Cryptography, yaani hash aur chabiyon ka jaadu kaise kaam karta hai.
