Mulle meeldib PHP<\/a><\/noindex> arenduse kiirus ja suurep\u00e4rane \u00fclekantavus. See on t\u00f5eliselt hea, kui taskus on alati valmisolekuga t\u00f6\u00f6riist probleemide lahendamiseks.<\/p>\n

<\/p>\n

Oli p\u00e4ris pettumust valmistav, kui tutvudes kohaliku plokiahela Waves Platform<\/a><\/noindex> arsenalis ei olnud valmis SDK-d PHP jaoks. Mis teha, tuli see ise kirjutada.<\/p>\n

<\/a><\/noindex><\/p>\n

Alguses tuli kasutada nodid<\/a><\/noindex> tehingute allkirjastamiseks. Seega, kolme konto haldamiseks tuli k\u00e4ivitada kolm node't... See oli hale vaatepilt, kuigi see lahendas m\u00f5ned probleemid. Kuni sain aru, et node'ide najale toetumine on ummiktee. Esiteks, funktsionaalsuse piirangute t\u00f5ttu API<\/a><\/noindex>, teiseks kiirusest (tol ajal olid node'd v\u00e4ga aeglased).<\/p>\n

<\/p>\n

Alustasin kahte paralleelset projekti. \u00dcks neist - luua plokiahela brauser, mis oleks kiire ja t\u00e4iesti s\u00f5ltumatu node'ite API-st. Teine - koguda k\u00f5ik funktsioonid Waves Platformiga t\u00f6\u00f6tamiseks \u00fchte kohta. Nii tekkisid projektid w8io<\/a><\/noindex> ja WavesKit<\/a><\/noindex>.<\/p>\n

<\/p>\n

Waves plokiahela backstage\u2019i esimeseks sammuks oli w8io brauser<\/a><\/noindex>. See polnud lihtne, kuid ikkagi \u00f5nnestus kirjutada s\u00f5ltumatu k\u00f5igi saldode arvutamine ja isegi leida viga originaalnode'ite arvutustes (bug-bounty programm<\/a><\/noindex> \u00dcldiselt toimib see, nad maksavad leitud vigade eest). Saate p\u00f5hjalikumalt tutvuda w8io brauseri funktsioonidega selles teemas: https:\/\/forum.wavesplatform.com\/t\/w8io-waves-explorer-based-on-php-sqlite<\/a><\/noindex><\/p>\n

<\/p>\n

W8io kallal t\u00f6\u00f6tades kahtlesin juba alguses, kuid kui t\u00f6\u00f6 j\u00f5udis loogiliselt l\u00f5pule ja asusin SDK loomise juurde, siis kahtlused kinnitust said. Ma ei suutnud leida teatud funktsioone, sealhulgas k\u00f5ige olulisemaid, kr\u00fcptograafilisi. Siis hakkasin oma elemente ehitama aluseks. Nii s\u00fcndisid: ABCode<\/a><\/noindex> base58 kodeerimiseks (tegelikult igasuguste t\u00e4hestike kodeerimiseks igasugustes), Curve25519<\/a><\/noindex> \u00fchtsete allkirjade loomise ja kontrollimise jaoks (variantidega steroididel<\/a><\/noindex>), Blake2b<\/a><\/noindex> \u00fche hash'i arvutamiseks (mis oli saadaval alates PHP 7.2) jne.<\/p>\n

<\/p>\n

Siin pean t\u00e4nama Inala Kardanovi<\/a><\/noindex> mitme v\u00e4\u00e4rtusliku n\u00f5uande eest, mis suunasid mind composer'i<\/a><\/noindex> suunal, selle asemel, et kasutada harjumusp\u00e4raseid, kuid aegunud include faile.<\/p>\n

<\/p>\n

M\u00f5ne kuu p\u00e4rast WavesKit n\u00e4gi ilmavalgust<\/noindex>, tuli v\u00e4lja beetaversioon<\/a><\/noindex> ja on n\u00fc\u00fcd valmis t\u00f6\u00f6tama koos kogu Waves platvormi standardfunktsiooniga. K\u00f5ik, mis on saadaval p\u00f5hiv\u00f5rgus<\/a><\/noindex> tehingud on lihtsasti loodud, allkirjastatud ja saadetud \u00fche paketi abil, mis t\u00f6\u00f6tab k\u00f5igis 64-bitistes PHP versioonides alates 5.6.<\/p>\n

<\/p>\n

Kuidas \u00fchendada WavesKit oma projektiga:<\/p>\n

<\/p>\n

composer require deemru\/waveskit<\/code><\/pre>\n
<\/p>\n
Kasutame:<\/p>\n
<\/p>\n
use deemruWavesKit;\n$wk = new WavesKit( 'T' );\n$wk->setSeed( 'manage manual recall harvest series desert melt police rose hollow moral pledge kitten position add' );\n$tx = $wk->txBroadcast( $wk->txSign( $wk->txTransfer( 'test', 1 ) ) );\n$tx = $wk->ensure( $tx );<\/code><\/pre>\n
<\/p>\n
\u00dclaltoodud n\u00e4ites loome objekti WavesKit, mis t\u00f6\u00f6tab testv\u00f5rgus «T». Seame sisseseade fraasi, mille p\u00f5hjal arvutatakse automaatselt v\u00f5tmed ja konto aadress avatud v\u00f5tme alusel. Seej\u00e4rel loome 0.00000001 Waves \u00fclekande automaatselt arvutatud aadressilt, mis p\u00f5hineb sisseseade fraasil, aadressile «test», edastame selle allkirjastamiseks erav\u00f5tmega ja saadame v\u00f5rku. P\u00e4rast seda kindlustame, et tehing on v\u00f5rgu poolt edukalt kinnitatud.<\/p>\n
<\/p>\n
Tehingutega t\u00f6\u00f6tamine keskendub funktsioonidele, mis algavad tx<\/a><\/noindex>. Tehingute l\u00e4hemaks m\u00f5istmiseks v\u00f5ite tutvuda WavesKit dokumentatsiooniga<\/a><\/noindex> v\u00f5i minna otse visuaalsete n\u00e4idete juurde aatritestide pideva integreerimise kaudu<\/a><\/noindex>.<\/p>\n
<\/p>\n
Kuna WavesKit on arenenud reaalse kasutamise tingimustes, on tal juba v\u00e4lja kujunenud arenenud funktsioone. Esimene peamine funktsioon on funktsioon ensure<\/a><\/noindex>, mis kontrollib n\u00f5utud usaldusv\u00e4\u00e4rsuse taseme saavutamist, et tehingut ei kadunud, vaid vastupidi, see on kinnitatud ja saavutanud vajalikud kinnitused v\u00f5rgus.<\/p>\n
<\/p>\n
Teine l\u00f6\u00f6gikindel mehhanism on see, kuidas WavesKit suhtleb s\u00f5lmedega. Kasvuhoone tingimustes t\u00f6\u00f6tab raamistik ainult peamise s\u00f5lmega, hoides selle pidevat \u00fchendust, kuid t\u00f5rgete korral v\u00f5ib automaatselt vahetada varus\u00f5lmede peale. Kui seadistate hulga varus\u00f5lmi, saate kutsuda funktsiooni setBestNode<\/a><\/noindex> , et m\u00e4\u00e4rata parim s\u00f5lm peamise s\u00f5lmena vastavalt hetke k\u00f5rguse ja vastamise kiirusen\u00e4itajale. N\u00fc\u00fcd lisage sellele sisemine p\u00e4ringute vahem\u00e4lu ja hoolitsete nii kasutajate kui ka s\u00f5lmade omanike eest.<\/p>\n
<\/p>\n
\u00dcks viimaseid arenenud mehhanisme on funktsioon txMonitor<\/a><\/noindex>. See tuli vajadusest reageerida sissetulevatele tehingutele reaalajas. See funktsioon lahendab t\u00e4ielikult k\u00f5ik blockchaini tehingute t\u00f6\u00f6tlemisega seotud n\u00fcansid. Ei mingit valu, lihtsalt seadistage oma callback-funktsioon soovitud valikutega ja oodake uusi tehinguid, mis k\u00e4ivitavad teie protsessid. N\u00e4iteks, veel \u00fcks minu projekt VECRO<\/a><\/noindex> v\u00f5i t\u00e4ielikult ehitatud selle funktsiooni \u00fcmber, saate rahulikult uurida, kuidas see t\u00f6\u00f6tab otse projekti koodis<\/a><\/noindex>.<\/p>\n
<\/p>\n
Mulle meeldib avatud l\u00e4htekood, see on \u00fcks inimkonna suurimaid saavutusi. Kuna ma olen ainus arendaja ja olen saavutanud seisundi, kus k\u00f5ik minu vajadused on rahuldatud, kutsun teid \u00fcles kasutama ja panustama WavesKit<\/a><\/noindex>.<\/p>\n
