Difficulty Bomb
Difficulty bomb ek aisa tareeqa-e-kaar tha jo waqt ke sath sath mining ki dushwari mein ahista ahista izafa karne wale
Ethereum ke code par banaya giya tha, jis se miners ke liye naye
blocks banana musalsal mushkil hota ja raha tha.
Isay network ki
proof-of-work se
proof-of-stake ki taraf muntaqili ki targheeb dene ke liye design kiya giya tha. Jab Ethereum launch hua to yeh miners par inhisar karta tha keh wo cryptographic puzzles hal kar ke transactions ki toseeq karein. Difficulty bomb is liye mutaarif karwaya gya tha taa keh ek schedule karda "Ice Age" banaya jaye jis mein block ke auqat waqt ke sath barhte jayein, taa keh
mining kam munafa bakhsh ho jaye aur ecosystem ko energy ke hawale se ziada muasar consensus model apnane ki targheeb di jaye.
Difficulty bomb 2015 mein block 200,000 par activate kiya giya tha. Is ki wajah se Ethereum ki mining ki dushwari pehle se tay shuda
block heights par tezi se barhti gayi. Jab difficulty bomb aage barhta gaya, to block ke auqat taqreeban 13 seconds se barh kar 20 seconds ya us se ziada ho gaye, jis se transaction ki processing sust ho gai aur hissa lene wale afraad ke liye mining musalsal kam munafa bakhsh hoti gai.
Proof-of-stake ki taraf muntaqili ke tayyar hone se pehle, Ice Age ko network mein khalal dalne se rokne ke liye, developers ne
hard forks ke zariye difficulty bomb ko kai martaba muakhar kiya. Yeh takheer mukhtalif marahil mein naafiz ki gayi, jin mein 2017 mein Byzantium upgrade, 2019 mein Constantinople, 2020 mein Muir Glacier, 2021 mein
London, aur 2021 aur 2022 mein
Arrow Glacier aur Gray Glacier upgrades shamil hain. Har taakhir ne bomb ko mustaqbil ki taraf dhakail diya, jis se developers ko proof-of-stake mechanism ko hatmi shakal dene ke liye waqt mil gya.
Difficulty bomb ke do eham maqasid thay. Pehla, is ne developers ke liye proof-of-stake ki taraf muntaqili ko mukammal karne ki deadline muqarrar ki, taa keh network ki taraqqi ruk na jaye. Agar yeh dabao na hota, to upgrade ko jald mukammal karne ki fori zarurat mehsoos na hoti. Doosra, is ne miners ko tabdeeli ke baad purane proof-of-work chain par kaam jari rakhne se roka, jis se is baat ka imkaan kam ho gaya keh koi ikhtilafi hard fork paida ho aur Ethereum blockchain aisi do chains mein taqseem ho jaye jo ek doosre ke muqable mein kaam kar rahi hon.
Ethereum ne 15 September, 2022 ko Merge naam ki ek upgrade ke zariye proof-of-stake par apni muntaqili mukammal kar li. Kiun keh network ab mining par inhisar nahi karta, is liye difficulty bomb bhi ab mazeed active nahi raha aur na hi is ka talluq Ethereum ke operations se hai. Is ne apna matlooba maqsad poora kar diya hai aur ab yeh Ethereum ki tareekh ka hissa hai.
