Yini I-Maximum Extractable Value (MEV)

I-Maximum Miner Extractable Value (MEV) isilinganiso sezinzuzo umvukuzi (noma isiqinisekisi, isilandeleli, njll.) angazithola ngokusebenzisa ikhono lakhe lokuhlanganisa ngokungafanele, ukukhipha, noma ukuhlela kabusha ukuthengiswa ngaphakathi kwamabhulokhi awakhiqizayo. Ake sibone ukuthi i-MEV iyini ngokujulile nokuthi isebenza kanjani.

Liyini Inani Eliphezulu Elikhiphekayo

I-Maximum Extractable Value, eyaziwa nangokuthi i-MEV, igama elisho inani eliphakeme levelu umvukuzi we-blockchain angalikhipha emsebenzini ngesikhathi esithile. Ngamanye amazwi, kuyisilinganiso senani lezomnotho abavukuzi abangalithola ngokulawula ukuhleleka kokuthengiselana ngaphakathi kwebhulokhi. I-MEV ingumqondo oye wazuza ukubaluleka emhlabeni we-cryptocurrencies kanye vimba eminyakeni yamuva, njengoba isibe yisici esibalulekile ekuqondeni indlela abasebenza ngayo abavukuzi be-blockchain nokuthi lokhu kungathinta kanjani ukuphepha nokuzinza kwenethiwekhi.

Lisebenza kanjani Inani Elikhiphekayo Eliphezulu

I-Maximum Extractable Value ikhiqizwa kusukela kumehluko phakathi kwevelu yezentengiselwano ezifakwe kubhulokhi kanye nenani lemisebenzi ebingafakwa uma i-oda labo belihlukile. Abavukuzi bangakwazi ukusizakala ngalo mehluko ukuze bathole inzuzo yezomnotho, bahlele kabusha ukuthengiselana ngaphakathi kwebhulokhi ukuze bathole i-MEV ephezulu engenzeka. Indlela abavukuzi abahlela kabusha ngayo ukuthengiswa ngaphakathi kwebhulokhi ukuze kwandiswe i-MEV isuselwe embonweni we-latency arbitrage. Lokhu kusho ukuthi abavukuzi bafuna ukusebenzisa ngokunenzuzo umehluko wesikhathi ekudlulisweni kolwazi phakathi kwama-node ahlukene kunethiwekhi, ukuxhaphaza ukuhleleka kokuthengiselana futhi bathole inzuzo enkulu. Ngokwesibonelo, ake sithi umvukuzi unemisebenzi emibili engu-A no-B engafakwa ebhulokhini. Umsebenzi A ubiza i-ETH engu-1 kanti okwenziwa ngu-B kuwu-2 ETH. Uma umvukuzi ehlanganisa ukuthengiselana A kuqala, inani eliphakeme angalikhipha kulokho kuthengiswa yi-1 ETH. Kodwa-ke, uma umvukuzi e-oda kabusha ukuthengiselana futhi ebeka ukuthengiselana B kuqala, inani eliphakeme angakwazi ukulikhipha kukho kokubili okwenziwe yi-3 ETH (2 ETH kusukela ku-B kanye ne-1 ETH kusukela ku-transaction A).

Izibonelo Zenani eliphezulu Elikhiphekayo

Esinye sezibonelo ezaziwa kakhulu ze-MEV ku-Ethereum blockchain yilokho okubizwa ngokuthi "ukuhlaselwa kwesandwich." Lokhu kuhlasela kwenzeka lapho umvukuzi esebenzisa ithuba lomehluko wokubambezeleka phakathi kokwenziwa kwemisebenzi emibili ukuze afake owakhe umsebenzi phakathi kwabo, ethola inzuzo yezomnotho kule nqubo. Esinye isibonelo se-MEV esibizwa ngokuthi “izindali zenani elikhiphekayo zabavukuzi,” ezisetshenziselwa abavukuzi ukuze bancintisane nelungelo lokufaka ukuthengiselana kubhulokhi elandelayo. Abahlanganyeli bendali babhida inani le-ETH ukuze umsebenzi wabo ufakwe kubhulokhi elandelayo, futhi umvukuzi owina endalini uthola inani eliphakeme elikhiphekayo kulokho kuthengiselana.
