Bija diezgan s\u0101p\u012bgi, kad iepaz\u012bstoties ar iek\u0161\u0113jo blok\u0137\u0113di Waves Platform<\/a><\/noindex> taj\u0101 nebija gatava SDK uz PHP. Nu, n\u0101c\u0101s to uzrakst\u012bt.<\/p>\n

S\u0101kum\u0101 n\u0101c\u0101s izmantot mezglus<\/a><\/noindex> dar\u012bjumu parakst\u012b\u0161anai. T\u0101tad tr\u012bs adres\u0113m bija j\u0101uzs\u0101k tr\u012bs mezgli\u2026 Tas bija no\u017e\u0113lojams skats, lai gan tas atrisin\u0101ja da\u017eas probl\u0113mas. L\u012bdz br\u012bdim, kad sapratu, ka pa\u013cauties uz mezgliem \u2014 tas ir aklu gals. Pirmk\u0101rt, ierobe\u017eot\u0101 funkcionalit\u0101te API<\/a><\/noindex>, otrk\u0101rt, \u0101truma d\u0113\u013c (tobr\u012bd mezgli bija \u013coti l\u0113ni).<\/p>\n

<\/p>\n

Es uzs\u0101ku divus paral\u0113lus darbus. Viens \u2014 izveidot blok\u0137\u0113des p\u0101rskatu, kas b\u016bs \u0101trs un piln\u012bgi neatkar\u012bgs no mezglu API. Otrais \u2014 apvienot visas funkcijas darbam ar Waves Platform vien\u0101 viet\u0101. T\u0101 rad\u0101s projekti w8io<\/a><\/noindex> un WavesKit<\/a><\/noindex>.<\/p>\n

<\/p>\n

Pirmais solis aiz Waves blok\u0137\u0113des bi\u013cetes bija p\u0101rskatu w8io<\/a><\/noindex>. Nebija viegli, bet tom\u0113r izdev\u0101s uzrakst\u012bt neatkar\u012bgu visu bilances apr\u0113\u0137inu un pat atrast k\u013c\u016bdu apr\u0113\u0137inos ori\u0123in\u0101lajos mezglos (bug-bounty programma<\/a><\/noindex> , starp citu, pie vi\u0146iem darbojas, par atrastaj\u0101m k\u013c\u016bd\u0101m maks\u0101). J\u016bs varat detaliz\u0113t\u0101k iepaz\u012bties ar w8io p\u0101rskata funkcionalit\u0101ti \u0161aj\u0101 t\u0113m\u0101: https:\/\/forum.wavesplatform.com\/t\/w8io-waves-explorer-based-on-php-sqlite<\/a><\/noindex><\/p>\n

<\/p>\n

Str\u0101d\u0101jot pie w8io, man jau bija \u0161aubas, bet kad darbs tuvoj\u0101s lo\u0123iskajam beig\u0101m un es uzs\u0101ku SDK izveidi, \u0161aubas apstiprin\u0101j\u0101s. Es nekur nevar\u0113ju atrast da\u017eas funkcijas, tostarp vissvar\u012bg\u0101k\u0101s, kriptogr\u0101fisk\u0101s. Tad es s\u0101ku veidot savus pamatus. T\u0101 \u010detri tika rad\u012bt: ABCode<\/a><\/noindex> base58 kod\u0113\u0161anai (paties\u012bb\u0101 jebkura alfab\u0113ta kod\u0113\u0161anai), Curve25519<\/a><\/noindex> lai izveidotu un p\u0101rbaud\u012btu sader\u012bgas parakstus (ar variantiem uz stero\u012bdiem<\/a><\/noindex>), Blake2b<\/a><\/noindex> viena no ha\u0161\u0101m apr\u0113\u0137in\u0101\u0161anai (kas bija pieejama tikai s\u0101kot no PHP 7.2) utt.<\/p>\n

<\/p>\n

\u0160eit es gribu pateikt paldies In\u0101lam Kardanovam<\/a><\/noindex> par da\u017eiem v\u0113rt\u012bgiem padomiem, kas novirz\u012bja mani uz composer<\/a><\/noindex> viet\u0101 no man ierastiem, bet novecoju\u0161iem, include failiem.<\/p>\n

<\/p>\n

P\u0113c p\u0101ris m\u0113ne\u0161iem WavesKit ieraudz\u012bja gaismu<\/noindex>, veiksm\u012bgi izn\u0101ca no beta versija<\/a><\/noindex> un tagad ir gatavs darbam ar visu standarta funkcionalit\u0101ti Waves platform\u0101.
