Un smart contract, c&rsquo;est un programme autonome qui va ex&eacute;cuter automatiquement des conditions d&eacute;finies au pr&eacute;alable. Si telle condition est bien v&eacute;rifi&eacute;e, alors telle cons&eacute;quence s&rsquo;ex&eacute;cutera d&rsquo;elle m&ecirc;me. C&rsquo;est donc bien un code informatique qui d&eacute;termine l&rsquo;ex&eacute;cution ou non d&rsquo;un contrat.<\/p><p>Un exemple concret pour comprendre ce qu&rsquo;est un smart contract : les assurances voyages. Une grande majorit&eacute; des passagers assur&eacute;s contre le retard de leur vol ne r&eacute;clament pas leur argent. Cela pourrait changer gr&acirc;ce aux smart contracts. Imaginons que toutes les donn&eacute;es relatives au transport a&eacute;rien soient mises sur la blockhain (heures d&rsquo;arriv&eacute;e et de d&eacute;part des vols, retards, liste des passagers, etc). On pourrait, gr&acirc;ce &agrave; un smart contract qui se connecterait &agrave; cette base d&rsquo;information, faire en sorte que les clients dont le vol est annul&eacute; ou en retard soient automatiquement rembours&eacute;s, sans m&ecirc;me en faire la demande. L&rsquo;indemnisation se ferait de fa&ccedil;on automatique et imm&eacute;diate.<\/p><p>Les smart contracts sont donc des &laquo; contrats auto-ex&eacute;cutants &raquo; qui b&eacute;n&eacute;ficient des avantages de la blockchain : les conditions de l&rsquo;accord sign&eacute; entre toutes les parties sont inscrites sur le r&eacute;seau de fa&ccedil;on transparente et irr&eacute;versible. <\/p><p>Si vous aimez les mots du monde des cryptos, allez faire un tour dans <a href=\"https:\/\/cryptonews.com\/fr\/exclusives\/guide-de-la-terminologie-crypto-1435\/\">notre section lexique<\/a>.
