Metadata
Update shuda Aug 18, 2026 Metadata se murad aisa data hota hai jo dosre data ke baray mein maloomat faraham karta hai, is ke features, maakhiz, ya saakht ki wazahat karta hai taa keh isay talash kar ke istemal karna aasan ho jaye.
Rozana ki computing mein, metadata har jagah mojood hota hai. Misal ke tor par, ek photo file mein jis din woh khenchi gayi thi woh tareekh, camera ka model, aur file ke size ka metadata shamil ho sakta hai, halan keh in mein se kuch bhi tasveer mein zahir nahi hota. Crypto mein, metadata aksar
transaction ki tafseelat ya kisi token ki khasusiyat ko bayan karta hai.
Ek
Blockchain par, kisi transaction ke record mein metadata shamil ho sakta hai jaisa keh timestamp, shamil addresses, transfer ki gayi raqam, aur adaa ki gayi fee. Yeh maloomat khud transfer ki gayi value nahi hotiin balkeh transaction ki wazahat karti hain.
Metadata khas tor par
non-fungible tokens (NFTs) ke liye eham hota hai. Blockchain par mehfooz kiya jane wala NFT asal mein milkiyat ka ek record hota hai. Metadata hi is token ko asal pehchan deta hai: is mein aam tor par naam, tafseel, tasveer ya media link, aur un khasoosiyat ki list mojood hoti hai jo item ko bayan karti hain. Metadata ke baghair, NFT sirf yeh dikhaye ga keh kis wallet ke paas kon sa token hai, lekin yeh nahi bataye ga keh woh token asal mein kis cheez ki numaindagi karta hai.
NFT metadata aam tor par do tareeqon mein se ek tareeqe se mehfooz kiya jata hai. On-chain metadata barah-e-raast
smart contract mein likha jata hai, jis se token khud-kafeel aur bairooni servers se aazad ho jata hai. Yeh tareeqa aam tor par ziada arse tak kaar-aamad sabit hota hai lekin ziada mehnga bhi hota hai kiun keh blockchain par data mehfoz karna mehnga ho sakta hai.
Off-chain metadata blockchain ke bahar mehfooz kiya jata hai, aur token mein file ko zahir karne wala sirf ek link mojood hota hai, jise aksar auqat token URI kaha jata hai. Yeh file kisi
centralized server ya
IPFS jaise kisi decentralized storage network par mojood ho sakti hai. Off-chain storage sasti hoti hai, lekin agar link karda location offline ho jaye to metadata ghair dastiyaab ho sakta hai. Isi liye storage ka intikhab NFT ki taweel muddati reliability ko mutasir kar sakta hai.
Metadata ko mehfooz karne aur banane ke tareeqay ke baray mein jaan kar users ko yeh jaanchne mein madad mil sakti hai keh token asal mein kis cheez ki numaindagi karta hai aur waqt ke sath us ki tafselaat ke qabil-e-rasai rehne ka kitna imkaan hai.
