Un moyen de revenu passif"},"content":{"rendered":"

Cela peut sembler un terme compliqu\u00e9, mais ce n'est pas un gros probl\u00e8me une fois que vous l'avez compris et mis en pratique, m\u00eame. Pour faire vite: Proof of Stake (PoS) est un type de syst\u00e8me num\u00e9rique (algorithme) pour parvenir \u00e0 un consensus dans une blockchain,<\/strong> ce qui signifie v\u00e9rifier les transactions et frapper de nouvelles pi\u00e8ces. Et oui, cela peut \u00e9galement \u00eatre un moyen de revenu passif, pour quiconque dispose de suffisamment de fonds.<\/p>\n\n\n\n

Alors\u2026 est-ce quelque chose comme l'extraction de crypto-monnaie? Eh bien, en quelque sorte. C'est fondamentalement une alternative au minage de crypto-monnaie traditionnel Proof of Work (PoW), qui est utilis\u00e9 par des pi\u00e8ces comme Bitcoin (BTC). Souvenons-nous un peu de cela.<\/p>\n\n\n\n

PoW est un autre algorithme<\/a>, et par \u00abalgorithme\u00bb, nous entendons un ensemble d'\u00e9tapes et de m\u00e9thodes qui sont construites - avec des math\u00e9matiques - pour obtenir un r\u00e9sultat sp\u00e9cifique ou r\u00e9soudre un probl\u00e8me. C'est exactement ce que fait le PoW: d\u00e9velopper un probl\u00e8me math\u00e9matique difficile ou une \u00e9nigme que l'\u00e9quipement du mineur doit r\u00e9soudre afin de v\u00e9rifier les transactions virtuelles. Ils gagneront ensuite quelques crypto-monnaies en r\u00e9compense de leurs services.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Ce mineur aura besoin d'un mat\u00e9riel puissant, d'une certaine quantit\u00e9 de connaissances techniques et de beaucoup d'\u00e9lectricit\u00e9 pour r\u00e9ussir sa t\u00e2che. Maintenant en Syst\u00e8mes PoS<\/a> (et pi\u00e8ces) la figure du \u00abmineur\u00bb est remplac\u00e9e par le \u00abvalidateur\u00bb. Ce validateur, qui peut \u00eatre n'importe qui qui le souhaite, n'aura pas besoin de beaucoup de cela. Au lieu, ce qu'ils vont faire, c'est verrouiller dans un portefeuille sp\u00e9cial une certaine quantit\u00e9 de jetons natifs qu'ils ont pr\u00e9c\u00e9demment acquis.  <\/strong><\/p>\n\n\n\n

Ainsi, ils obtiendront le droit de v\u00e9rifier les transactions et de frapper de nouvelles pi\u00e8ces, si n\u00e9cessaire, et presque automatiquement. Et ils seront r\u00e9compens\u00e9s pour cela, comme un revenu passif. Cela a cependant ses inconv\u00e9nients.<\/p>\n\n\n\n

Quel est le probl\u00e8me avec PoS, alors?<\/strong><\/h2>\n\n\n\n

La r\u00e9ponse courte \u00e0 cela est la s\u00e9curit\u00e9 fournie au r\u00e9seau. Arr\u00eatons-nous un peu ici pour parler des fourches. Vous savez, la plupart des crypto-monnaies sont sauvages et libres de tout droit d'auteur, open source et d\u00e9centralis\u00e9es. Cela signifie toute personne ayant les connaissances peut copier et coller sa propre version de la m\u00eame crypto-monnaie: c'est une fourchette<\/strong>, car ils peuvent diviser le r\u00e9seau pour le prendre dans une autre direction.<\/p>\n\n\n\n

Pour le dire plus clairement, Bitcoin en esp\u00e8ces<\/a> (BCH) est, par exemple, un fork de Bitcoin<\/a> (BTC). Ils ont la m\u00eame histoire jusqu'en 2017, lorsque BCH s'est scind\u00e9 dans une autre direction et avec de nouvelles fonctionnalit\u00e9s. Mais bon, ils fonctionnent tous les deux avec PoW, pas avec PoS. Cela signifie que les mineurs auraient alors d\u00fb d\u00e9cider entre eux deux. Leur puissance de calcul, leurs efforts acharn\u00e9s ne peuvent pas \u00eatre partag\u00e9s avec deux cha\u00eenes, car cela reviendrait \u00e0 d\u00e9penser deux fois le m\u00eame argent.<\/p>\n\n\n\n

\"Deux-Bitcoin-Cash-survivant\"<\/figure>\n\n\n\n

C'est en fait un risque avec les syst\u00e8mes PoS. Avec PoW, cela n'a pas de sens de cr\u00e9er des fourchettes sans fin, mais dans PoS, elles peuvent \u00eatre rentables pour les tricheurs. Ainsi, l'utilisateur peut sauter entre la cha\u00eene d'origine o\u00f9 il a d\u00e9j\u00e0 d\u00e9pens\u00e9 de l'argent et la nouvelle cha\u00eene o\u00f9 il ne l'a pas fait<\/strong>, for example.  There\u2019s no \u201cwork\u201d to verify the transactions here, only stakeholders.<\/p>\n\n\n\n

Les d\u00e9veloppeurs travaillent sur ce probl\u00e8me \u00e9ventuel. Des punitions pour mauvais comportement ont \u00e9t\u00e9 propos\u00e9es, comme couper ou confisquer les enjeux des tricheurs. C'est un travail en cours, cependant. Et les syst\u00e8mes PoW pr\u00e9sentent \u00e9galement certains inconv\u00e9nients.<\/p>\n\n\n\n

Alors, quel est le probl\u00e8me avec PoW?<\/strong><\/h2>\n\n\n\n

Le principal probl\u00e8me susceptible de susciter des pr\u00e9occupations l\u00e9gitimes \u00e0 propos de ce syst\u00e8me est probablement le facteur environnemental. PoW blockchains<\/a> sont pour la plupart solides et s\u00e9curis\u00e9s, mais le co\u00fbt est l'\u00e9nergie (\u00e9lectricit\u00e9) d\u00e9pens\u00e9e par le mat\u00e9riel pour r\u00e9soudre les \u00e9nigmes math\u00e9matiques (le travail).<\/p>\n\n\n\n

Selon le Cambridge Center for Alternative Finance (CCAF<\/a>), Bitcoin (par exemple) a une consommation \u00e9nerg\u00e9tique annuelle estim\u00e9e \u00e0 environ 12,65 TWh<\/strong>. Pour la perspective, c'est plus que des pays comme la Finlande, la Suisse et le Portugal.<\/p>\n\n\n\n

Consid\u00e9rant<\/a> que chaque 1 KWh produit environ 1 livre de dioxyde de carbone (CO2) lib\u00e9r\u00e9e dans l'atmosph\u00e8re (et la pollue), ce qui signifierait environ 6,4 Mt (millions de tonnes) de CO2 chaque ann\u00e9e. Bien s\u00fbr, cela ressemble plus \u00e0 un petit chiffre, compar\u00e9 \u00e0 d'autres activit\u00e9s, industries et pays.<\/p>\n\n\n\n

\"PoS-revenu-Bitcoin-\u00e9nergie\"
Bitcoin est loin derri\u00e8re les plus gros consommateurs d'\u00e9nergie au monde. Source: CCAF<\/figcaption><\/figure>\n\n\n\n

Le secteur bancaire produit environ 319,5 Mt de CO2 par an. L'exploitation aurif\u00e8re produit 69,4 Mt de CO2, les \u00c9tats-Unis 1 951 Mt de CO2 et la Chine 2 782 Mt de CO2. Au-del\u00e0, comme indiqu\u00e9 \u00e9galement par le CCAF, Bitcoin prend \u00e0 peine 0.49% de la consommation totale d'\u00e9nergie.<\/strong><\/p>\n\n\n\n

De plus, une \u00e9tude r\u00e9alis\u00e9e par la firme CoinShares<\/a> a r\u00e9v\u00e9l\u00e9 que les crypto-mineurs utilisent pour s'\u00e9tablir dans des endroits o\u00f9 l'\u00e9lectricit\u00e9 est moins ch\u00e8re, pour faire plus de profits. Et une \u00e9lectricit\u00e9 moins ch\u00e8re signifie g\u00e9n\u00e9ralement des sources d'\u00e9nergie renouvelables (et non polluantes), comme l'hydro\u00e9lectricit\u00e9. Donc, cette question est toujours en discussion.<\/p>\n\n\n\n

Les pi\u00e8ces PoS comme revenu passif<\/strong><\/h2>\n\n\n\n

Mettre de c\u00f4t\u00e9 quel syst\u00e8me est le meilleur (une r\u00e9ponse n'est pas encore \u00e9tablie, de toute fa\u00e7on), il est certain que les gens peuvent gagner des revenus passifs simplement en gardant des pi\u00e8ces PoS dans leur portefeuille.<\/strong> Plus vous en avez et plus vous les verrouillez (inutilis\u00e9s), plus vous pouvez gagner de revenus (dans cette m\u00eame devise).<\/p>\n\n\n\n

Vous pouvez le consid\u00e9rer comme quelque chose de similaire aux comptes d'\u00e9pargne, mais probablement avec plus d'int\u00e9r\u00eats. Et, nous devrions dire, avec probablement plus d'argent en jeu \u00e9galement. Devenir un validateur de PoS n'a pas l'habitude d'\u00eatre bon march\u00e9, pr\u00e9cis\u00e9ment. C'est parce que le principe principal de ce syst\u00e8me est que leurs utilisateurs doivent vraiment s'int\u00e9resser au bien-\u00eatre du r\u00e9seau.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Nous pouvons utiliser quelques exemples ici. R\u00e9cemment, Ethereum publi\u00e9<\/a> son premier syst\u00e8me PoS. Pour en devenir un futur validateur, les utilisateurs doivent avoir verrouill\u00e9 32 ETH (maintenant autour de $41.6k) dans le portefeuille qui lui est destin\u00e9. Selon le calculateur (exp\u00e9rimental) fourni par Prix Ethereum<\/a>, cela impliquerait environ 8,91 TP1T en int\u00e9r\u00eats annuels gagn\u00e9s.<\/strong><\/p>\n\n\n\n

Les chiffres varient selon les pi\u00e8ces de PoS. Demandes de Dash<\/a> une garantie de 1000 tokens ($105,700) pour ses validateurs PoS et offre un int\u00e9r\u00eat annuel d'environ 6%. D'autre part, dans Cosmos (ATOM)<\/a> il existe diff\u00e9rents niveaux de jalonnement. Le premier ne n\u00e9cessite pas de montant sp\u00e9cifique au minimum, vous pouvez le faire facilement \u00e0 partir de portefeuilles comme Portefeuille atomique<\/a>, et le b\u00e9n\u00e9fice calcul\u00e9 est de 8% par an. Le niveau suivant (pour les validateurs officiels) est cependant plus difficile \u00e0 atteindre. Les co\u00fbts<\/a> sont au-dessus de $57k.<\/p>\n\n\n\n

En conclusion? Les pi\u00e8ces PoS peuvent g\u00e9n\u00e9rer un tr\u00e8s bon revenu passif, mais pas sans un bon investissement.<\/strong> Quoi qu'il en soit, au cas o\u00f9 vous seriez int\u00e9ress\u00e9, vous trouverez ici un liste des pi\u00e8ces PoS<\/a> choisir. Mais n'oubliez pas de faire vos propres recherches (DYOR<\/a>) premier!<\/p>\n\n\n\n
