Bitcoin ha delle limitazioni quali la velocit\u00e0 e il costo delle transazioni.<br \/>\nUn periodo particolarmente denso di transazioni, fee non abbastanza alte e blocchi ogni 10 minuti, possono rendere davvero lento e costoso il vostro acquisto o spostamento da un wallet ad un altro.<\/p>\n<p><em>Lightining network dovrebbe risolvere tutte queste problematiche .<\/em><br \/>\nIl concetto di questo sistema \u00e8 sviluppato dal 2015 e dobbiamo immaginare che lavori come se fosse una torta a strati.<br \/>\nSullo strato 1 abbiamo Bitcoin con la sua blockchain mentre sullo strato 2 abbiamo il sistema di lightning network.<br \/>\nQuesta caratteristica viene creata appositamente per i micropagamenti, cos\u00ec che tutte le micro transazioni non vengano scritte sulla blockchain di bitcoin.<br \/>\nAlmeno non immediatamente.<\/p>\n<p>Vengono cos\u00ec creati i payment channel. se voglio inviare fondi ad un mio amico o ad un negoziante possiamo aprire un payment channel tra noi due, con i nostri pagamenti che non coinvolgono la blockchain principale. La transazione avverr\u00e0 alla velocit\u00e0 con cui i due wallet riescono a comunicare tra loro.<br \/>\nA chiusura completa delle transazioni tra i due wallet, si verr\u00e0 a creare una transazione principale che verr\u00e0 scritta sulla BC principale.<br \/>\nOra, se pensassimo ad una serie di transazioni abituali, di piccola entit\u00e0, come per esempio il caff\u00e8 al bar tutte le mattine, ogni transazione inviata alla blockchain principale di bitcoin ci costerebbe pi\u00f9 in tempo perso e fee che la transazione stessa.<br \/>\nHa senso spendere 1 euro di caff\u00e8 e 2 di commissioni?<\/p>\n<p>NO<\/p>\n<p>Ora ipotizziamo di aprire un payment channel per tutto il mio team di CY Mood con il mio barista preferito.<br \/>\nAll\u2019apertura del canale di pagamento entrambe le parti depositano una certa somma di denaro a garanzia delle transazioni totali.<br \/>\nSe so che il mio team beve 100 caff\u00e8 a settimana depositer\u00f2 una somma uguale o superiore.<br \/>\nSulla BlockChain principale di bitcoin vi saranno solo 2 transazioni, ovvero la prima transazione di apertura del payment channel e deposito della moneta e una seconda per &#8220;chiudere&#8221; o completare il pagamento.<br \/>\nOra se torniamo al nostro secondo strato, all&#8217;interno del canale di pagamento possono avvenire migliaia milioni di transazioni senza che queste vengano scritte sull BC principale. Il mio team potr\u00e0 bere migliaia di caff\u00e8 e ogni volta che comprano,si scriver\u00e0 una transazione di X btc verso il barista.<br \/>\nSettimanalmente, mensilmente o ogni volta che il mio amico barista vorr\u00e0 incassare i bitcoin del caffe, decider\u00e0 di scrivere la transazione sulla BlockChain principale.<\/p>\n<p>Il sistema funziona al meglio per le piccole transazioni che si ripetono, possiamo pensare al nostro panettiere o dal barbiere.<br \/>\nEsiste ovviamente un sistema contro le truffe, per chi volesse chiudere il canale di pagamento in anticipo e non pagare nulla.<br \/>\nIn questo caso, il totale del deposito iniziale verrebbe inviato al truffato. Questo scoraggia di molto le truffe.<br \/>\nUn&#8217;altra interessante capacit\u00e0 di Lightning network \u00e8 la possibilit\u00e0 di fare pagamenti a persone con cui non abbiamo un canale aperto, ma sfruttando i canali delle altre persone.<\/p>\n<p>Per saperne di pi\u00f9 sui wallet <a href=\"https:\/\/cymood.com\/web\/2021\/12\/04\/bitcoin-wallet-i-vari-tipi\/?lang=it\"><strong>clicca qui.<\/strong><\/a><\/p>\n<p>Per saperne di pi\u00f9 sui pericoli e su come restare al sicuro in questo mondo <a href=\"https:\/\/cymood.com\/web\/2022\/10\/13\/security-guide-for-newbies-save-the-user\/?lang=it\"><strong>clicca qui<\/strong><\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Bitcoin e Lightning Network, una delle soluzione pensate ai problemi di bitcoin.
