Kya aap Blockchain ke bare me jante hai agar nahi jante toh ye blog post bilkul apke liye hai. Aap Bitcoin  ke bare me toh jante hi honge ya sune honge toh bas bitcoin ka record rakhne wale technology ko hi blockchain kaha jata hai. Plus blockchain banking, cryptocurrencies aur investing ke alag alag charan se bhi relate karta hai.

Blockchain Kya Hai?

Hum blockchain nam sunte hi bahut complicated sa lagta hai aur sahi me ye thora complicated bhi hai, lekin iska core concept bahut hi simple hai. Ye blockchain ek prakar ka database hai aur blockchain ko samajh ne ke liye apko database samajh na hoga.

So basically, database pieces of information ke collection ko kaha jata hai jo electronically stored rehta hai computer system mein. Database ka structure table format me hota hai taki koi particular information ko search karne me asani ho.

Spreadsheet database se alag isiliye hai kyunki spreadsheet ek single person ke liye designed kiya hota hai jabki database ko bahut sare log ek bare use kar sakte hai.

Blockchain aur database me bas itna hi fark hai ki blockchain groups me information collect karta hai jise 'blocks' bhi kaha jata hai.

Har ek blocks ki limited storage capacity hoti hai isiliye jab ek block bhar jata hai toh pehle bhare huye block se jur jata hai aur ese hi ek information ki chain ban jati hai. 

Blockchain ka purpose digital informations ko record aur ditribute karne ki permision deti hai lekin edit karne ki nahi. Toh hum ye bol sakte hai ki har ek blockchain database hota hai lekin har ek database blockchain nahi hota.

Blockchain kaise kam karta hai ?

3 main important concepts shamil hai blockchain me: blocks, nodes, miners.

1. Blocks

Ek chain bahut sare blocks ke jurne se banta hai aur ek block me 3 basic elements present rehta hai:
  • Data
  • Ek 32-bit whole number jise nonce kaha jata hai. Nonce randomly generate hota hai jab ek block banta hai, jo ki bad me ek block header hash ko generate karta hai.
  • Ek 256-bit number ka hash jo nonce ke sath jura rehta hai. Aur ye bht sare zeros ke sath suru hota hai (matlab bahut chota hota hai).
Jab ek chain ka pehla block create hota hai, tab nonce ek cryptoghraphic hash generate karta hai aur jo data us block me rehta hai wo hamesa ke liye nonce aur hash se jur jata hai jab tak ki use mined na kia jaye.

2. Miners

Miners wo hota hai jo mining ke madad se naya blocks create karta hai. Ek blockchain me har ek block ka apna khud ka nonce aur hash hota hai, aur sath hi ek block apne pichle wale block ke hash ko bhi carry karta hai chain me. Isiliye block mining karna bht hard hota hai especially jab chain bht lamba ho.

Miners special software use karte hai bahut hi hard complex math ko slove karne ke liye taki wo nonce finde kar sake jo ki hash generate karta hai.

Kyunki nonce 32-bit aur hash 256-bit ka hota hai isiliye roughly 4 billion nonce-hash combinations ko mined karna padta hai perfect combination pane ke liye.

Aur jab ye ho jata hai miners ko 'golden nonce' milta hai aur ek naya block chain me add ho jata hai. Ek block ko change karne ke liye re-mining ki jarurat hoti hai aur isse block ke sath-sath block ke piche ke sare block bhi change ho jate hai.

Isiliye block chain me changes karna bahut muskil hota hai. Ise aap ek tarah ki safety feature bhi samajh sakte hai. Jab ek block successfully mined ho jata hai tab network me sare nodes use accept karte hai aur miner ko financially reward kia jata hai.

3. Nodes

Decentralization (kisi ek ke pass control nahi rehna) blockchain technology ka sabse important concept hai. koi ek particular computer ya organization chain ko own nahi kar sakta hai. Balki, ye technology ek distributed ledger (khata bahi) hai jo via nodes chain se connected rehta hai.

Nodes hum kisi bhi prakar ke electric device ko khete hai jo blockchain ke copies ko maintain karta hai or network ko chalu rakta hai.

Har ek nodes ka apna copy hota hai blockchain ka aur network ko jaruri hai kisi bhi naye mined kiye block ko algoroithmically approve karna taki chain update aur varified ho sake. 

Blockchain bahut hi transparent hai kyunki ledger me kiye gaye kisi bhi prakar ke change ko hum dekh sakte hai. Har ek participent ka apna unique alphanumeric ID hota hai jo uske transaction ko show karta hai.
