EIP-4844: Mis on Dencun?<\/h2>\n

Dencun on Ethereum’i suurim v\u00e4rskendus, mis toob kaasa blob-andmete k\u00e4sitlemise. S\u00f5na \u201eblob” viitab massiivsetele andmekogumitele, mis on loodud suurema skaleeritavuse jaoks, aga ei sisalda tehinguid otse. See on nagu massiivne laual, kuhu saad visata info plahvatuslikult, ilma et iga t\u00fckk \u00fcksikult loendataks.<\/p>\n

Miks see on kriitiline?<\/h3>\n

Kujuta ette, et su andmevoog on t\u00f5rjutud l\u00e4bi \u00f5hu, kuid see \u00f5hk on t\u00e4is \u00f5hku, mis ei kanna kaalu. EIP-4844 eemaldab selle koormuse, laseb node’idel salvestada vaid “blob” viiteid, mitte kogu sisu. Tulemuseks on kiirem blokivahetus, madalam latentsus.<\/p>\n

Kuidas blob t\u00f6\u00f6tab?<\/h3>\n

Blobi andmed p\u00f5imuvad eelseisvate plokkidega, kuid need on eraldatud. Node’id peavad need andmed ainult ajutiselt hoidma. See on nagu \u00fchekordne foto, mis kaob, kui see on vaadatud. Nii v\u00e4heneb p\u00fcsiva salvestuse n\u00f5udlus.<\/p>\n

Tehniline s\u00fcgavus<\/h2>\n

Blob-suurus on piiratud 128\u202fMiB-ni, mis t\u00e4hendab, et suurus on m\u00e4rkimisv\u00e4\u00e4rne, kuid kontrollitud. Blobi juurdep\u00e4\u00e4s toimub KZG-kommitiidi kaudu – l\u00fchidalt, kr\u00fcptograafiline t\u00f5end, mis kinnitab andmete \u00f5igsust. Kui KZG-kommitiit ei klapi, l\u00fckkab s\u00fcsteem blobi \u00e4ra.<\/p>\n

V\u00f5imalikud l\u00f5ksud<\/h3>\n

\u00dcks risk on, et arendajad v\u00f5ivad ekslikult eeldada, et k\u00f5ik andmed on p\u00fcsivad. Vale. Blob on m\u00f5eldud l\u00fchiajalisteks, n\u00e4iteks rolli-p\u00f5histeks andmeteks. Kui sa salvestad midagi, mida pead tulevikus vajaduse korral s\u00e4ilitama, on vaja eraldi kahte – \u00fcks blob, \u00fcks traditsiooniline state.<\/p>\n

Praktiline m\u00f5ju<\/h2>\n

Rollup-lahendused saavad n\u00fc\u00fcd pakkuda madalamat tasu, sest nende tehingud saavad “blob” kanda. See on nagu hinnanguline hind, mis l\u00fckkab k\u00fctusekulu alla. Projektid, mis varem v\u00f5itlesid transaktsioonitasude koormuse all, tunnevad kohe leevendust.<\/p>\n

Lisaks, Dencuni rolli-metaandmete salvestus v\u00f5imaldab “data availability sampling” – l\u00fchiajaline kontroll, et k\u00f5ik nodid saavad vajalikud andmed.<\/p>\n

Toimintakava<\/h2>\n

Alusta testnetis, rakenda blob-andmeid oma protokollile, j\u00e4lgi KZG-kommitiidi valideerimist, ja hakat\u00e4ida oma rakendus uue tasuga. Siin on k\u00e4sk: seadista oma node KZG-koodi ja loo esimene blob-plokk juba t\u00e4na.<\/p>\n","protected":false},"excerpt":{"rendered":"
