blockchain technology

Assalamu Alaikum Dosto!

BlockChain

Aam tor par, blockchain, ek distributed ledger technology, ek malumat ke sath kaam karne ka zariya hai. Yeh ek digital database (registry) hai jo network participants ke transactions ke bare mein malumat ko barqarar rakhta hai, jisme decentralization (distributed), transparency, aur data ki unchangeability jaise asoolon ka paalan kiya jata hai. Is case mein, is tarah ke network mein shamil computers uske barabar independent nodes hote hain (peer-to-peer network).
In sab blocks ek chain banate hain: har naya block cryptography ki madad se pichle block se juda hota hai - data ko confidentiality aur protection ke liye encryption methods ka istemal karte hue. Khaas karke, naya block pichle block ka cryptographic hash contain karta hai, yani ke uska ek unique identifier code jo letters aur numbers ki ek string form mein hoti hai, sath hi ek timestamp, transaction ki date, aur ek electronic digital signature bhi hoti hai, kehta hai ek mahir.
Ek blockchain network public ho sakti hai jab koi bhi shamil ho sakta hai, ya private ho sakti hai agar participants ka circle limited hai. Network ka type is par depend karta hai ke participants ko identify kiya jana chahiye ya anonymity mumkin hai. Is network mein individuals, legal entities, government agencies, aur alag alag associations shamil ho sakte hain. Har participant network mein kai nodes rakhsakta hai. Corporate blockchain networks bhi hote hain, jo ek hi organization ke alag alag divisions ke nodes se bante hain.
Har node network mein blockchain ka ek digital registry ka copy rakhta hai, jisse practically kisi bhi data ki manipulation ya distortions ko almost eliminate kiya ja sakta hai. Blockchain smart contracts ka istemal karta hai - computer algorithms jo khud-ba-khud data ko control karte hain aur parties ke dvara kiye gaye commitments ko enforce karte hain - alag alag transactions ko conduct karne ke liye.

Decentralization

Distributed ledger technology ki ek key property decentralization hai, yani ke ek single decision-making center ki technological absence aur participants ki equality. Blockchain participants ko ek dusre par malumat exchange karne aur transactions karne ke liye ek dusre par trust nahi karna padta - trust technical level par diya jata hai.
Is tarah se, ek single trusted environment banata hai industry business processes ki automation aur counterparties aur kabhi kabhi competitors ke beech interaction ke liye.
Aaj tak, blockchain ke kuch economic effects identify kiye gaye hain. Inme document flow process mein transaction costs mein significant reduction shamil hai, sath hi mutual settlements par kharch hone wale time mein kami bhi hai. Iske alawa, technology aik large number of counterparties ko ek single business process mein integrate karne ke doran capital aur operating costs ko bhi kam kar sakti hai. Yeh information ki transparency ko bhi badha deti hai, aur, as a result, disputes aur litigation ke costs ko kam karti hai.
Aam tor par, ek single trusted decentralized environment banane se na ke sirf current business processes ki optimization hoti hai, balki yeh new business models ki bhi wajah ban sakti hai.

Immutability

Immutability ke aam tor par matlab hai ke data ko create hone ke baad change nahi kiya ja sakta. Software development mein shamil logon ko data immutability ki ahmiyat pata hoti hai. Blockchain ke context mein, data immutability bohot zaroori hai. Iska kyun yeh hai? Chaliye bitcoin ka example lete hain. Sabhi bitcoin transactions (wherever they come from) network par distributed taur par multiple copies ke roop mein record hote hain. Yahan ham links ko ek chain ke sath juda hua imagine kar sakte hain. Ab sochtiye ki agar is data ko change kiya ja sakta hai. Is case mein, koi bhi transaction history ko change karke billionaire ban sakta hai bas kuch lines ko sahi karke! Isliye, data ke blocks mein ki gayi immutability ek bohot important point ban jati hai.
Ek naye transaction ke liye, aap network ko transaction ke data ke sath ek message bhejte hain. Lekin kaise pata chalega ke yeh aap the, aur aapke neighbor nahi? Iske liye, bitcoin wallet ya doosra bitcoin software jo aap istemal karte hain, aapke private key se ek digital signature create karta hai, jo sirf aapko (aapki system) ke liye unique hota hai aur har transaction ke liye alag hota hai. Doosre log aapke message ko decrypt karne ke liye corresponding public key ka istemal karenge.
Toh data ki integrity kaise achieve hoti hai, kaise pata chalta hai ki attackers aapke message ko tamper nahi kar rahe hain? Digital signatures ke peeche ka principle yeh hai: agar koi message change hoti hai, toh signature invalid ho jati hai, aur phir sabko immediately pata chalta hai ke record mein kuch badlav kiya gaya hai.

Transparency

Kuch log kehte hain ke blockchain privacy provide karta hai, jabke doosre kehte hain ke yeh transparent hai. Aapko lagta hai iska yeh kyun hota hai?
Ek individual ki identity sophisticated cryptography ke through chupai jati hai aur sirf unke public address ke zariye represent hoti hai. Is tarah se, agar aap transaction history dekhna chahte hain, toh aapko "Bob ne 1 BTC bheji" nahi dikhega, balki aapko

"1MF1bhsFLkB9vpFYEmvwT2TbyCt7NZJ ne 1 BTC bheji" dikhega.

Is tarah se, jabki ek individual ki asal identity protected hoti hai, aap unke public address par ki gayi saari transactions ko dekh sakte hain. Yeh level of transparency pehle financial system mein kabhi nahi dekha gaya tha. Yeh bhi darust hai ke kuch bade institutions ko ek aur zaroori level of accountability ki zarurat hoti hai.
Sirf cryptocurrency perspective se baat karte hain, agar aapko kisi bade company ka public address pata hai, toh aap usko ek conductor mein daal kar dekh sakte hain ki unki saari transactions kya hain. Yeh unhe honest rehne par majboor karta hai, jo ke unko pehle kabhi deal nahi karna pada.
Lekin yeh best use case nahi hai. Hum sure hain ke zyadatar yeh companies cryptocurrencies ka istemal nahi karenge, aur agar karte hain bhi, toh unka saara transaction cryptocurrencies ke istemal ke nahi honge. Lekin agar blockchain technology integrate ho jaaye... keh sakte hain, unke supply chain mein? Aap samajh sakte hain ke aisa kuch financial industry ke liye bohot beneficial ho sakta hai, hai na?

Blockchain Kaise Kaam Karta Hai?

Blockchain existing options se zyada secure technology hai information store karne ke liye. Is wajah se agar registry ek single database mein hoti hai, toh usme hack ho sakta hai, destroy ho sakta hai, unauthorized changes ho sakte hain, lekin chain ke case mein, har node ke liye yeh sab karna padega. Yeh users ke individual computers par stored hote hain jo duniya bhar mein hote hain, isliye theoretically yeh hacking impossible hai.
Chaliye ek example lete hain. Misal k tawar par ek user ne Louvre se ek tasveer khareedi hai aur use apne dost ko dena chahta hai. Iske bare mein data ek naye item ke roop mein chain mein enter kiya jata hai. Kyunki yeh entry pichle ki "image" ko contain karta hai, isko forgeries ke khilaf protected kiya gaya hai. Is tarah se, ek individual element ko change karna mushkil hai, kyun ki "hack" kiya gaya element stored by the "neighbor" ke stored image ke sath match nahi karega.
Blockchain ek unique technology hai jo kuch important advantages provide karta hai:

• Sab type ke assets ke records ko store karne ki anumati deta hai: virtual aur tangible;
• Asset transfer ke transactions puri tarah anonymous hote hain, kyun ki sender aur recipient ka identifier sirf wallet number hota hai;
• Transactions bilkul reliable hote hain kyunki yeh impossible hai ke transactions ke information ko network ke sab nodes par change kiya ja sake;
• Blockchain destroy nahi ho sakta. Transaction data har network participant ke computer par stored hoti hai. Ek node ki loss network ke saare system ke performance ko affect nahi karta.

Miners Ka Kirdar

Jaisa ke hamne pehle kaha, blockchain systems decentralized hote hain, yani ke transactions ko system ke kai special participants - miners - process karte hain. Aam taur par, jo bhi sahi equipment aur software ke sath equipped hai, woh ek miner ban sakta hai.
Miners ke functions blockchain systems mein ye hote hain:

• Data ke copies store karna, jo system ko data loss aur information tampering se bachata hai;
• System mein transactions ko confirm karna;
• Doosre miners dvara kiye gaye transactions ko verify karna;

Toh miners ko kya motivate karta hai ke woh blockchain systems mein transactions ko log karein aur conduct karein? After all, mining equipment cheap nahi hota. Aam taur par, motivation transaction conduct karne ke liye system se milti hai, sath hi transaction participants dvara miner ko transaction process karne ke liye di jane wali commissions bhi hoti hai. Is tarah se, for example, bitcoin miners ki remuneration ka amount duniya bhar mein $0.5-1 million tak pahunch sakta hai!
Yeh yaad rakhna zaroori hai ke sirf mining ke liye equipment kharidna aur blockchain se connect karna enough nahi hai. Aapko phir bhi sabse tez transaction conduct karni hoti hai, kyunki reward sirf unko mil sakta hai jo transaction encryption code pahle offer karein, yani ke blockchain mein ek naya block create karein. Lucky woh miners hote hain jo transactions ko process karne ke liye sabse powerful equipment ke saath equipped hote hain, jabki network ke baaki participants bahar reh jaate hain.

Blockchain Real World Mein Explaination

Shuruwat mein, sirf bitcoin hi dusri coins se bada popular tha. Aajkal, phir bhi, market mein ek hazar panch so se zyada alag alag altcoins mojood hain. Inke perspectives ko dekhte hue har shakhs yeh decide kar sakta hai ke kaunsa cryptocurrency payments ke liye istemal karega aur kaunsa sirf invest karega. Cryptocurrency exchanges, alag alag projects, aur individual businessmen apne services ke zariye clients ko capital manage karne mein aasan access provide karte hain, jaise trading, exchanging, card par withdraw karne, aur aise kai aur kaam.
Chaliye ab blockchain technology ke idea ko behtar samajhne ke liye sabse popular cryptocurrencies ki taraf badhte hain.[LIST][*] Bitcoin Blockchain
Bitcoin ek definance act ke roop mein invanted hua tha. Cryptocurrency global economic crisis ke turant baad aayi thi aur ise traditional financial system ki nainsafi aur corruption ke liye ek ilaaj ke roop mein promote kiya gaya tha. Creators yakeen rakhte the ke jab bitcoin popular hoga, toh yeh real funds ke saath competition karega aur dheere dheere woh institutions ko supplant karega jo crisis ka karan bane the.
Bitcoin ne yeh services replace karne ki koshish ki jo in intermediaries dwara di ja rahi thi, ek khaas code aur cryptography ke zariye. Jab ek shakhs mortgage pay karta hai, toh uske bank aur doosre financial institutions ke beech background mein ek series of transactions hoti hai, jo funds ko user ke account se withdraw karti hai. Bank ye keh sakti hai ke finances ke saath sab kuch theek hai kyunki uske paas information hoti hai ke har ek penny account se kahan aur kaise kharch hua tha.
Bitcoin aur doosri cryptocurrencies yeh background transactions ko aur transactions ko software, ek distributed aur secure database, blockchain ke zariye badal deti hain. Is tarah se, multiple computers bitcoin token ownership ke process ko control karte hain. Cryptocurrency ka istemal bilkul kisi ko bhi kiya ja sakta hai, unki nationality ya residence ke bina.[*] Ethereum Blockchain
Blockchain technology sirf transactions ke liye hi nahi useful ho sakti. Lagbhag turant hi bitcoin ke utpann hone ke baad, logon ne sochna shuru kiya ke technology ko doosre areas mein kaise apply kiya ja sakta hai. Jab miners transactions ko check karte hain, toh woh chhote programs chalate hain jo transaction ke liye zaroori data ko process karte hain aur provide karte hain. Lekin kya humein kuch advanced programs chalane ka mauka mile, jaise social networking software? Ya phir blockchain ko online forums ke liye data provide karne ke liye istemal kiya ja sakta hai?
Yeh ideas bitcoin ke banne ke turant baad aaye, lekin kuch saal baad Toronto ke ek nineteen-year-old student ne inki development mein contribute ki. 2013 mein, Vitalik Buterin ne ek bilkul nayi technology banayi jise Ethereum kehte hain. Iski madad se blockchain sirf transactions ke liye hi nahi, balki aur bhi cheezein karne ke liye istemal ho sakti hai.
Bitcoin ke opposite, Ethereum smart contracts kehte hain, jo mini-programs hote hain. Inhe unlimited complexity ke saath likha ja sakta hai. Users in programs ke saath transactions bhej kar unse interact kar sakte hain, jo phir miners dwara process kiye jaate hain.
Iska matlab hai ke koi bhi ek program ko ek transaction mein embed kar sakta hai aur yeh guarantee kar sakta hai ke woh blockchain mein unchanged aur available rahega. Theoretically, Ethereum ke saath, Facebook, Twitter, Uber, ya koi aur digital service ko transparent, censor-proof, aur human intervention ke bina replace kiya ja sakta hai.[*] Blockchain Wallet
Seedha seedha toh cryptocurrency khud kahi store nahi hoti, lekin blockchain wallet ka maksad digital keys ko store karna hota hai jo ek address tak access aur transactions bhejne ki capability provide karte hain. Yaad rakhein ke cryptocurrency transactions ko undo nahi kiya ja sakta, isliye agar aap cryptocurrency ke saath deal karna chahte hain, toh aapko ek secure blockchain wallet hona chahiye.
Blockchain network mein transactions karne ke liye - aapko special wallets ki zaroorat hoti hai data store karne ke liye, jaise ki purchased cryptocurrency ke baare mein malumat. Yeh online, desktop, mobile, ya hardware wallets ho sakte hain. Online blockchain wallet ko aap 5-10 minutes mein kisi bhi specialized financial portal par register karke khol sakte hain. Desktop wale mein ek application ko PC par install karna padta hai, aur mobile wale ko communicator par. Hardware wallets - data store karne ke liye ek flash drive, inmein se zyada reliable hote hain kyunki unka constant Internet access nahi hota, aur is wajah se unhe hackers hack nahi kar sakte. Lekin transactions karne ke liye aapko bar-bar cryptocurrency ko hardware se doosre wallets aur vice versa bhejna padega.
Wallet ki malumat aur transactions ko encryption se protect kiya jata hai. Asset ke buyer aur seller transaction ko cryptographic keys ke saath confirm karte hain - special unique digital codes ke saath. Lekin cases aaye hain jahan online blockchain wallets ko hackers ne compromise kiya hai, isliye behtar hai ke data ko thumb drive par offline store karein. Ek blockchain transaction lagbhag turant hota hai, lekin transaction ko process aur confirm hone mein 10-15 minutes lag sakte hain.
Aam taur par, blockchain wallets anonymity assume karte hain, yani ke transaction karne wala kon hai, woh identify nahi kiya ja sakta. Yeh aapke assets ko curious eyes se bachane mein madad karta hai, lekin ismein additional risks bhi hote hain - agar aap apne wallet ke credentials bhool jaate hain, toh aap apne assets ko kho dete hain.
Blockchain wallet ki security ka dhyan rakhna real wallet ki security se kam nahi hai. Yeh user ki zimmedari hoti hai ke woh coins tak pahunchane ke liye keys ko secure rakhe.
Kuch tareeqe hain funds ko electronic wallet mein secure karne ke liye.

• Ek mushkil password ka istemal karen. Yeh letters, numbers, aur symbols ko shamil karna chahiye, jo 16 characters ya usse zyada hote hain. Ek strong password ko special programs se generate kiya ja sakta hai. Ye baat made-nazar rakhein ke password ko bhoolne ya kho dene se bachayein. Lamba password yaad rakhna mushkil hota hai, isliye ise kisi safe jagah par likh kar rakkhein.
• Apne wallet ko encrypt karen. Aap apne wallet ya smartphone ko khaas services se encrypt kar sakte hain. Yeh fund ko protect karega agar koi dusra vyakti unhe withdraw karne ki koshish karta hai. Yeh method malefactors ke khilaf nahi bachayega, jo keyloggers ka istemal karke aapke keyboard par type kiye gaye characters ko trace kar sakte hain.
• Online services se bachen. Yeh abhi tak sabhi coins ko secure rakhne ke liye kaafi nahi hain. Agar aap inka istemal karte hain, toh dhyan se choose karen aur dual authorization ka istemal karen.
• Apne funds ko kai wallets mein baant den. Kuch funds ko convenient aur accessible wallet mein chhod den, aur baaki ko ek aur secure jagah par rakh den. Is tarah, agar aap dhoka khaate hain, toh aapko sirf thoda nuksan hoga.
• Ek backup copy banayein. Aapke system ya computer mein kisi error ke hone ki sambhavna ko humesha nahi nikaal sakte, isliye advance mein ek copy bana lein. Regularly copies banate rahen taki aapko koi bhi address na khone pade. Copy ko bhi encrypt karna chahiye.
• Cold storage ka istemal karen. Iska matlab hai ek wallet jo network se connect nahi hota. Yeh aapke savings ko rakhne ka sabse surakshit tareeka hai. Iske liye aapko ya toh ek khaas hardware device kharidni padegi ya fir ek aise computer par transactions sign karna padega jo network se disconnect ho.

Blockchain Ka Istemal

Blockchain development ko bade companies aur corporations drive kar rahe hain jo technology ko apne business processes mein integrate kar rahe hain. Lagbhag sabhi un prototypes aur "pilots" ko launch kar rahe hain aur technology ka economic effect assess karne ki koshish kar rahe hain.
Blockchain ko mainly financial sector mein wide taur par istemal kiya jaa raha hai, jahan iska istemal funds transfer ke intermediate steps ko khatam karne aur transactions ki accuracy ko badhane mein madad karta hai. Bankon ke nazariye se, blockchain ko contracting, transactions ko register karna, aur customer ki identity ko confirm karne jaise functions ke liye istemal kiya ja sakta hai.
CB Insights ke mutabiq, Swiss bank UBS aur British bank Barclays blockchain ko back-office operations aur settlements ko tezi se karne ka ek tareeka banane ke roop mein experiment kar rahe hain, jise banking industry ke kuch log intermediary costs ko $20 billion tak kam kar sakte hain.
Blockchain ko aaj kal cross-border transactions ki cost ko kam karne ka ek solution ke roop mein bhi istemal kiya ja raha hai, jise McKinsey ne 2017 mein global transaction revenue ka 27% hone ka estimate kiya tha. Santander aur Western Union, for example, blockchain company Ripple ke saath partnership banaye hain taki cross-border payments ko efficient banaya ja sake.
Lekin blockchain application sirf banks, insurance companies, aur fintech startups se limit nahi hai: yeh technology ab retail se lekar aviation tak kai areas mein badh chuki hai.
For example, Data Insight analysts ne commerce ke liye blockchain ko ek key technology bataya hai kyunki iska istemal loyalty programs, customer digital ID management, aur direct sales mein kiya ja sakta hai. CB Insights ke mutabiq, blockchain gift aur loyalty cards ko sasta aur surakshit bana sakta hai, kyun ki inke issuance mein involved hone wale intermediaries ki quantity ko kam kar deta hai.
Iske alawa, technology customers ko counterfeit aur fraud ke khilaf additional protection provide kar sakti hai. For example, LVMH ne Microsoft aur blockchain startup ConsenSys ke saath collaborate karke ek platform banaya hai jisse luxury goods ko authenticate kiya ja sakta hai. Isse customers ko apne products ko design se distribution tak track karne ki suvidha milti hai.
Blockchain khaas taur par wahaan effective hai jahaan transactions ko authenticate karna aur smart contracts ko apply karna zaroori hai, jaise pharmaceuticals ke sale mein.
Logistics mein, blockchain ko supply chain monitor karne ke liye istemal kiya ja raha hai - isse food products ki freshness aur origin ko control karna aasan ho jata hai aur luxury goods ki authenticity guarantee ki ja sakti hai.
Blockchain ke zariye goods ke production se sale tak ke transactions ko permanent decentralized record mein document kiya ja sakta hai, jo time delays ko kam karta hai aur additional costs aur human error se bachata hai.
For example, companies jaise ki Walmart aur Sam's Club ne IBM Food Trust blockchain platform join kiya hai. Retailers ne apne suppliers se, jinko mainly fresh leafy vegetables ke specialization hai, unse request ki hai ki woh apne product data ko ismein enter karein. Is system ka istemal food ke origin ko jaldi track karne ke liye kiya ja raha hai, jo substandard batches ke source ko dhundhne ko kaafi aasan bana sakta hai.
Aviation mein, technology luggage aur cargo ko track karne mein madad karti hai, maintenance aur repair systems ko monitor karti hai, spare parts ko trade karti hai, aur pilot ki qualifications ko verify karti hai.
CB Insights ke analysts ke mutabiq, health care institutions ko yeh takleef hoti hai ke woh data ko securely share nahi kar sakte, jabki aise share karne se accurate diagnoses aur treatment ki effectiveness ko badhaya ja sakta hai. Blockchain, jo data security aur integrity ensure kar sakta hai, isme madad kar sakta hai.
For example, IBM ne MiPasa ko support karne ka elan kiya hai, jo ek open platform hai coronavirus ke confirmed data ke liye jo Hyperledger Fabric ke distributed blockchain network par bana hua hai. MiPasa pehle se hi World Health Organization (WHO), U.S. Centers for Disease Control and Prevention (CDC), Israeli Ministry of Health, aur doosre relevant agencies se data receive karta hai.
Project ki website par yeh likha gaya hai ki isko companies jaise Oracle aur Microsoft bhi support kar rahe hain. Dusre blockchain-enabled industries mein real estate, education, utilities, government, energy, gaming and entertainment, hospitality, aur law shamil hain.

Blockchain Mein Invest Kaise Karein

Toh yahaan teen tareeqe hain blockchain technology mein invest karne ke, sabse risky se lekar sabse safe tak.

• Coins aur Tokens mein Invest karna: Jaise ki humne pehle bhi mention kiya hai, cryptocurrencies blockchain nahi hain, lekin is technology ke application mein invest karne ka sabse seedha tareeka yeh hai. Yeh method bhi sabse risky hai. Yahan ki bet sirf blockchain technology par nahi hai, jo ke badhta ja raha hai, balki yeh bhi hai ke log sahi tareeke se is technology ka istemal karenge, unka concept sahi hai, unke paas ek code aur dhyan se socha gaya tareeka hai ise istemal karne ka, aur unka business model haqeeqatan mein kaam karega. Yeh saare typical startup risks hain.
  Coins aur tokens mein invest karne se aap yeh bhi bet kar rahe hain ki inke creators ne departing train par chadhne ka faisla nahi kiya hai, unke morals decent hain, aur company ko hack, cheat, blackmail, ya lawsuit ka samna nahi karna padega.
• Coin investing ke liye humara sabse accha advice yeh hai: apna due diligence karein aur coins ko alag-alag platforms se kharidne ke liye funds kharch karein. Phir in coins ko apne wallet mein daal dein aur consider karein ki woh kho gaye hain, phir unhein dus saal baad find karein, jaise ki 50-Cent ne kiya.
• Startups mein Invest karna jo blockchain technology ka istemal karte hain: Blockchain startup mein invest karna cryptocurrency mein invest karna se kam risky hai.
  Kuch interesting blockchain projects technology par based hain aur sirf currency par nahi. Yeh projects aaj kal pharmaceuticals, finance, real estate, product sourcing, virtually har industry mein emerge ho rahe hain jismein open digital traceability ki zarurat hoti hai. Lekin kai log samajhte hain ke is technology ka successful application abhi nahi mila. Abhi thoda early hai, lekin itna early bhi hai aur winners abhi dikhayi nahi denge.
  Agar aapke paas means aur ichha hai ki aap ek blockchain startup mein invest karen, toh yeh shayad aapki pehli startup nahi hogi. Jaise har investment mein hota hai, apna research karein, apna due diligence karein, lekin sabse important baat yeh hai ki company blockchain ko bas blockchain ke liye istemal kar rahi hai, woh kisi existing problem ka solution nikalne ki koshish kar rahi hai, balki temporary lekin tempting solution dhundhne ki jagah kisi problem ko solve karne ki koshish kar rahi hai.
• Exchange-Traded Funds (ETFs) mein Invest karna: Yahaan, risk ka level crazy se casual tak gir jata hai, aur yeh invest karne ka sabse asaan tareeka bhi hai. Yeh ek kaafi naya concept hai; kuch (kam se kam likhne ke waqt) exchange-traded funds hain jo aapko blockchain companies ko track karne ki permission dete hain. Yeh ek aise basket hota hai jo companies ke exchange-traded stocks ko shamil karta hai jo blockchain ka istemal karte hain ya blockchain aur cryptocurrencies se related hain.

Sabhi clear taur par batate hain ki woh cryptocurrencies mein seedhe invest nahi kar rahe hain, isliye yeh tareeka bade hadd tak safe hai. Problem yeh hai ki yeh mushkil hai jaanna ke companies asal mein kitni blockchain se judi hui hain. Iske baare mein chalte hain, hum kuch blockchain companies ke baare mein baat karenge.

Blockchain Stocks: 2024 ke Liye Top 5 Blockchain Stocks

Jab pehli baar traders blockchain investments ke baare mein keh rahe hain, toh unhe standard cryptocurrency trading yaad aati hai. Lekin, is field mein return milne ka ek popular aur munafa bakhsh option stocks mein invest karna ho sakta hai jo actively digital technology ka istemal karte hain. Humne paanch organizations ko select kiya hai jo blockchain-based products offer karte hain.

• DocuSign: Company Ethereum blockchain ka istemal karti hai client agreements sign karne ke liye. DocuSign electronic signature technologies ke developers ke beech market leader hai. 2015 mein, company ne blockchain-based smart contract ka ek public prototype banane mein shaamil hua tha. Likha gaya hai ki stock is waqt $116.13 mein trade ho raha hai.
• Alibaba: Yeh China aur duniya ke ek bade virtual marketplaces mein se ek hai, jo customers ko affordable prices aur wide range of products ke saath attract karta hai.
  Ant Technology Group, Alibaba Group ke fintech division ne ek blockchain-based cross-border trade settlement platform launch kiya hai, jiska naam Trusple hai. Reuters ke mutabiq, yeh platform, jo ki company ke khud ke blockchain Antchain par chalti hai, SMEs aur financial institutions ke liye hai. Isse sellers aur buyers ko trade orders place karne ki permission milti hai, jiske basis par platform automatically smart contracts generate karta hai saare zaruri information ke saath.
  Order execute hota hai toh smart contract mein key data update hota hai - isme various logistical data bhi shamil hai. Payments counterparties ke beech Antchain network par hoti hain. Ye procedures bhi automatically hoti hain, jisse cross-border trade transactions efficient aur cheaper ho jaate hain.
• Nvidia: Software aur hardware vendor ki scale aur ecosystem company ko metaverse mein active participate karne mein madad karte hain. Nvidia ne Omniverse beta testing launch kiya hai. Company blockchain technology par bhi dhyan deti hai, jo metaverse develop karne mein istemal hoti hai aur cryptocurrencies ke mining ke liye chips banati hai.
  Abhi ke liye, NVIDIA ke shares technology securities ke saath gir rahe hain due to correction in U.S. markets, Federal Reserve ke rates ke expected badhne, aur QE program ko accelerate karne ke expectations. Yeh Treasuries ko push karta hai, jise shares, aur khaas karke NVIDIA, itni sensitive hoti hain.
• Square: Investors Cash App ke through direct bitcoin trade kar sakte hain. Square Crypto open-source projects develop karta hai. Company ke blockchain developments ka focus hai bitcoin ko duniya ke sabse popular currency banane mein madad karna. Pata chala hai ki Square apne balance sheet par 8 thousand bitcoins rakhta hai. Iske alawa, company ne installment payment service Afterpay ko bhi acquire kiya hai. Isse Square stock ko woh investors ke liye attractive banata hai jo fintech companies mein invest karte hain. Is waqt, company kuchh around 118.00 mein trade ho rahi hai.
• Overstock dot com Yeh ek puchasing U.S. online store hai jo bitcoin ko payment ke taur par accept karne wale pehle online marketplaces mein se ek tha. Overstock apne subsidiary Medici Ventures ke through blockchain-related projects mein active invest karta hai. Yeh pehle ek fund mein transform ho gaya hai jo Pelion Venture Partners dwara manage kiya jata hai, jo jaldi hi blockchain startups ko develop karne ka iraada rakhta hai. Analysts ke mutabiq, yeh Overstock stock prices mein ek bullish trend ke liye ek prerequisite hai.

Am taur par, yeh worth mentioning hai ki cryptocurrencies ke field mein actively developing technologies un technologies se bade fayde le sakte hain jo banking institutions aur payment systems mein istemal hoti hain. Lekin iske saath hi koi guaranteed prediction nahi di ja sakti cryptocurrency market aur digital currencies ke rate ki stability ke baare mein. Isme spontaneity aur kisi bhi regulators ki absence hoti hai, isliye invest karte waqt aapko selected coin ke prospects ka andaza lagana hoga bina excitement aur emotion ke aur sirf proven resources se aayi information ka istemal karna chahiye.

BlockChain Technology ke jadoo ka aghaaz 2008 mein, ek ya ek se zyada anonymous shakhs ya group ke tahat ek shakhs ne bitcoin ki peshkash ke sath hua. Ye shakhs ya group Satoshi Nakamoto ke naam se mashhoor hain, lekin aaj tak unka asal shakl ya shakhsiyat nahi pata chal saki. Satoshi Nakamoto ne ek whitepaper jari kiya jismein wo cryptocurrency bitcoin aur uske peeche ke blockchain technology ke concepts ko bayan kiya.
Blockchain ek digital ledger hai jo decentralized hai, yaani ke ismein kisi bhi ek central authority ki zaroorat nahi hoti. Har transaction ko ek block ke roop mein store kiya jata hai aur har block ko pehle wale block se link kiya jata hai, isliye iska naam blockchain hai. Ye tamam transactions kisi bhi computer network par store kiye jaate hain jo blockchain network ka hissa hai.

Blockchain technology ke kuch ahem features hain jinse ye dusri traditional technologies se behtar hai:

1. Decentralization: Jaise ke pehle zikar kiya gaya, blockchain decentralized hota hai, iska matlab ye hai ke kisi bhi ek central authority ya institution ki zaroorat nahi hoti hai transactions ke liye.

2. Transparency: Blockchain ke sabhi participants ke transactions public hoti hain. Ye transparent hone ka matlab hai ke koi bhi individual ya organization ek transaction ke sahi hone ka asani se pata laga sakta hai.

3. Security: Har ek block ke sath cryptographic hash hota hai jo us block ki integrity aur authenticity ko maintain karta hai. Is tarah ke cryptographic techniques ke istemal se blockchain secure hota hai.

4. Immutability: Once a transaction is recorded on a blockchain, it's extremely difficult to alter it. Ye tamam transactions permanent hoti hain aur unmein kisi bhi tarah ki change karna nearly impossible hai.

Blockchain technology ne aaj tak kai sare sectors mein apna istemal dekha hai. Cryptocurrencies jaise Bitcoin aur Ethereum blockchain technology ka pramukh istemal hain lekin iske ilawa finance, healthcare, supply chain management, voting systems, aur bohot se aur domains mein bhi iska istemal hota hai.

Blockchain technology ke faide ke sath, challenges bhi hain jaise ke scalability, energy consumption, aur regulatory concerns. Lekin phir bhi, is technology ka istemal tezi se barh raha hai aur future mein aur bhi innovative applications dekhne ko milenge.

BlockChain Technology ek naye digital era ka aghaaz hai jo ke dunya ko ek naye tareeqay se transactions karne aur data ko store karne ka moqa deta hai. Iska istemal aaj aur bhi zyada taraqqi kar raha hai aur agle arsey mein iska aur bhi gehra asar dekhne ko mil sakta hai

Blockchain technology ko aam tor par digital currency, jese ke Bitcoin, Ethereum, aur Litecoin, ke peechay hone wali technology ke tor par jaana jaata hai, lekin iska istemal aaj kal bohot si aur maqsadon ke liye kiya ja raha hai. Blockchain ek decentralized database hai jo transactions ko secure tarikay se record karta hai. Iski sab se khaas baat ye hai ke ismein data ko ek bar record karne ke baad usay badalna ya delete karna mushkil hota hai.
Har ek block ek chain mein hota hai, aur har block mein transactions ke data hota hai. Har block mein ek hash hota hai jo us block ki identity ko define karta hai aur us block ke peechay wale block ka reference rakhta hai. Is tarah, jab naya data block mein shaamil hota hai, to wo purani blocks ki security ko bhi barqarar rakhta hai.

Blockchain ki technology ke fawaid mein data security, transparency, aur tamper-proof records shamil hain. Iski security ko barqarar rakhne ka tareeqa decentralized nature hai, jis mein data ko multiple nodes (computers) par distribute kiya jata hai. Agar kisi ek node ya server mein koi tabdeeli ya nuqsan ho, to bhi puri system kaam karti rehti hai.

Is technology ka istemal financial transactions, supply chain management, healthcare records, voting systems, aur bahut si aur jagahon mein ho raha hai. Halankay, iski kuch limitations bhi hain, jese ke energy consumption, scalability, aur regulatory concerns.
