Sequencer yeh tay karta hai keh kon si transaction pehle ki jaye gi aur settlement ke liye sargarmi ko package karta hai. Mazeed wazeh andaz mein batayein to yeh ek layer-2 network ke hisse ki surat mein aam tor par ek rollup hota hai, jo user transactions mosool karta hai, unhein tarteeb deta aur unhein bunyadi layer-1 blockchain par post karne se pehle batches ki surat mein jama karta hai.

Kai rollups mein, user apni transaction kisi awami intezar ki jagah ke bajaye barah-e-raast sequencer ko bhejta hai. Sequencer check karta hai keh aaya transaction darust hai ya nahi, Is se user ko ek fori "ibtadai tasdeeq" mil jati hai keh transaction qabool kar li gayi hai, aur yeh layer 1 par finalize hone se kaafi pehle mosool ho jati hai.

Is ke baad sequencer kai transactions ko compressed data ke ek single block mein ikatha kar deta hai aur us batch ko layer-1 chain par post kar deta hai. Jab batch layer 1 par record ho jata hai, to sequencer ki tay karda tarteeb rollup ki mustaqil history ka hissa ban jati hai. Is tarah sargarmi ko ek sath bundle karna rollups ki fees kam rakhne ka ek eham tareeqa hai.

Sequencer ke paas kaafi ikhatyarat mojood hote hain kiun keh yeh order ko control karta hai. Aaj ke dour mein kai rollups ek hi operator ki janib se control karda sequencer par chal rahe hain. Yeh tareeqa muassar sabit hota hai, lekin yeh centralization ke hawale se tashweesh paida karta hai: agar yeh offline ho jaye to network ruk sakta hai, aur jo shakhs order ko control karta ho, mumkin hai keh woh transactions ko tarteeb de kar maximal extractable value (MEV) hasil kar le. Isi wajah se misal ke tor par shared ya barre barre istemal hone wale sequencers ke zariye sequencer ko decentralized banana taraqqi ki janib ek eham qadam hai.
