Les mineurs font tourner du mat\u00e9riel sp\u00e9cialis\u00e9 qui court pour r\u00e9soudre une \u00e9nigme cryptographique ; le gagnant ajoute le bloc suivant et empoche la r\u00e9compense plus les frais. L&rsquo;\u00e9nigme n&rsquo;a pas de raccourci, donc la seule fa\u00e7on de gagner plus souvent est de d\u00e9penser plus de puissance de calcul, ce qui rend justement une attaque trop co\u00fbteuse pour en valoir la peine.<\/p>\n<h2>Exemple chiffr\u00e9<\/h2>\n<p>Sur Bitcoin, les mineurs s&rsquo;affrontent environ toutes les dix minutes pour la r\u00e9compense de bloc actuelle. Le r\u00e9seau ajuste la difficult\u00e9 pour que les blocs arrivent \u00e0 ce rythme quelle que soit la puissance ajout\u00e9e. Plus il y a de mineurs, plus chacun a besoin de puissance pour la m\u00eame part de r\u00e9compenses, d&rsquo;o\u00f9 une \u00e9conomie du minage en course permanente entre prix du coin, co\u00fbt de l&rsquo;\u00e9lectricit\u00e9 et efficacit\u00e9 du mat\u00e9riel.<\/p>\n<h2>Minage ou exposition de trading<\/h2>\n<p>Le minage est une op\u00e9ration \u00e0 forte intensit\u00e9 de capital : mat\u00e9riel, \u00e9nergie, refroidissement et disponibilit\u00e9. La plupart de ceux qui veulent une exposition \u00e0 un coin ne le minent pas ; ils l&rsquo;ach\u00e8tent. Sur Volity, vous prenez une exposition spot ou CFD aux grands coins sans aucun mat\u00e9riel, et les CFD permettent la vente \u00e0 d\u00e9couvert, ce qu&rsquo;un mineur ne peut structurellement pas. Le minage est une entreprise ; le trading est une position.<\/p>\n<h2>Pourquoi c&rsquo;est important<\/h2>\n<p>Le minage lie la s\u00e9curit\u00e9 d&rsquo;un coin \u00e0 un co\u00fbt \u00e9nerg\u00e9tique r\u00e9el, ce qui est l&rsquo;argument de la durabilit\u00e9 de la preuve de travail et l&rsquo;argument contre sa consommation.
