Qualifi\u00e9e par certains visionnaires de technologie r\u00e9volutionnaire, la Blockchain<\/em> fait aujourd\u2019hui de plus en plus parler d\u2019elle. Le monde entier s\u2019y int\u00e9resse et les investissements dans le domaine se multiplient. De nombreuses entreprises et administrations explorent actuellement les usages possibles de cette technologie prometteuse mais complexe \u00e0 appr\u00e9hender pour les m\u00e9tiers.<\/p>\n

Pourtant, ce concept n\u2019est pas nouveau\u00a0: la Blockchain<\/em> est la technologie sur laquelle s\u2019appuie la crypto-monnaie Bitcoin, apparue en 2009. Mais alors, pourquoi ce regain d\u2019int\u00e9r\u00eat\u00a0? Quelles sont les caract\u00e9ristiques de cette technologie et quels usages peut-elle favoriser ? Quels sont les obstacles \u00e0 surmonter pour qu\u2019elle puisse se d\u00e9mocratiser\u00a0?<\/p>\n

Des algorithmes remplacent le tiers de confiance<\/h2>\n

La Blockchain<\/em> est une technologie qui permet aux membres d\u2019un m\u00eame r\u00e9seau d\u2019effectuer en toute confiance des op\u00e9rations de stockage et de transmission d\u2019informations, appel\u00e9es \u00ab\u00a0transactions\u00a0\u00bb, et ce en toute confiance, sans aucune autorit\u00e9 centrale de contr\u00f4le.<\/p>\n

Cette technologie se pr\u00e9sente sous la forme d\u2019un registre contenant l\u2019ensemble des transactions enregistr\u00e9es depuis sa cr\u00e9ation (dans le cas de la Blockchain<\/em> Bitcoin<\/em>, il s\u2019agit par exemple de l\u2019int\u00e9gralit\u00e9 des transactions financi\u00e8res effectu\u00e9es depuis la cr\u00e9ation de cette crypto-monnaie). Ce registre dispose de 2 caract\u00e9ristiques essentielles\u00a0:<\/p>\n

    \n
  • Il est distribu\u00e9<\/strong>: tous les membres du r\u00e9seau disposent d\u2019une copie du registre, rendant quasiment impossible la modification de ce registre par un individu sans l\u2019aval du reste du r\u00e9seau\u00a0;<\/li>\n
  • Il est fiabilis\u00e9 par les acteurs du r\u00e9seau<\/strong> \u2013\u00a0: la confiance \u00e9tablie au sein du syst\u00e8me est assur\u00e9e par les membres du r\u00e9seau eux-m\u00eames\u00a0; aucune autorit\u00e9 centrale ne joue le r\u00f4le de tiers de confiance.<\/li>\n<\/ul>\n

    Au sein du registre, les transactions sont regroup\u00e9es dans des \u00ab\u00a0blocs\u00a0\u00bb enchain\u00e9s par ordre chronologique (dans le cas de la Blockchain Bitcoin<\/em>, un bloc correspond \u00e0 environ 10 minutes de transactions). Le sch\u00e9ma ci-dessous permet de comprendre la cin\u00e9matique de cr\u00e9ation d\u2019un nouveau bloc, et donc l\u2019enregistrement d\u2019une nouvelle transaction dans la Blockchain<\/em>.<\/p>\n

    Cin\u00e9matique de rajout d\u2019un Bloc \u00e0 la Blockchain – Vision globale<\/h3>\n
    \"Blockchain<\/figure>\n

    Ainsi, le tiers de confiance est remplac\u00e9 par des algorithmes permettant\u00a0\u00e0 tous les membres du r\u00e9seau de v\u00e9rifier facilement que les mineurs n\u2019ont pas ajout\u00e9, supprim\u00e9 ou modifi\u00e9 une transaction lors de la cr\u00e9ation des nouveaux blocs.<\/p>\n

    Du simple stockage s\u00e9curis\u00e9 \u00e0 l\u2019ex\u00e9cution de \u00ab\u00a0contrats\u00a0\u00bb intelligents<\/h2>\n

    Toute situation faisant intervenir un tiers de confiance co\u00fbteux ou faillible est une opportunit\u00e9 pour cr\u00e9er un cas d\u2019usage Blockchain<\/em>. Banque, immobilier, sant\u00e9, transport\u2026 tous les secteurs se sentent concern\u00e9s et r\u00e9fl\u00e9chissent actuellement aux opportunit\u00e9s offertes par la Blockchain<\/em> pour am\u00e9liorer ou remplacer les mod\u00e8les actuels.<\/p>\n

    Trois cat\u00e9gories de cas d\u2019usage se distinguent\u00a0aujourd\u2019hui :<\/p>\n

      \n
    • Record keeping <\/em><\/strong>\u2013 Blockchain<\/em> utilis\u00e9e comme registre de stockage pour d\u00e9poser des donn\u00e9es dont on souhaite garantir la preuve de par leur existence, leur date de cr\u00e9ation et le droit de propri\u00e9t\u00e9, comme par exemple\u00a0:\u00a0des brevets, des donn\u00e9es m\u00e9dicales, etc.<\/li>\n
    • Digital transactions <\/em><\/strong>\u2013 Blockchain<\/em> utilis\u00e9e pour du transfert de valeur : transaction immobili\u00e8re, crowdfunding, crypto-monnaies, etc.<\/li>\n
    • Smart-contracts <\/em><\/strong>\u2013 Blockchain<\/em> utilis\u00e9e pour d\u00e9velopper et stocker des smart-contracts<\/em>, \u00e0 savoir des contrats entre plusieurs parties, r\u00e9dig\u00e9s sous forme de code informatique, et qui s\u2019ex\u00e9cutent sans intervention humaine selon les conditions et termes qu\u2019ils contiennent.<\/li>\n<\/ul>\n

      Les acteurs du monde de la finance s\u2019int\u00e9ressent tout particuli\u00e8rement \u00e0 la Blockchain<\/em>. Que ce soit en France ou \u00e0 l\u2019international, de nombreuses initiatives sont men\u00e9es, parfois sous forme de consortium, dans le but d\u2019\u00e9valuer le potentiel des usages de cette technologie dans le secteur et de d\u00e9finir des protocoles standardis\u00e9s.<\/p>\n

      Bien que la Blockchain<\/em> ait \u00e9t\u00e9 initialement pens\u00e9e comme un syst\u00e8me public, la plupart des r\u00e9flexions actuelles concernent des Blockchains<\/em> priv\u00e9es (propre \u00e0 une organisation) ou hybrides (propre \u00e0 un ensemble de partenaires).<\/p>\n

      Performance, \u00e9cologie et r\u00e9glementation\u00a0:\u00a0les obstacles \u00e0 surmonter<\/h2>\n

      \u00c0 titre d\u2019exemple, le r\u00e9seau Bitcoin permet d\u2019enregistrer environ 7 transactions par seconde, \u00e0 comparer aux 2 000 transactions par seconde de VISA. Pour s\u2019imposer \u00e0 large \u00e9chelle et d\u00e9velopper de nouveaux cas d\u2019usage, la Blockchain<\/em> doit donc pouvoir am\u00e9liorer ses performances.<\/p>\n

      Le d\u00e9fi de la performance repose sur une d\u00e9finition et un calibrage des param\u00e8tres intrins\u00e8ques \u00e0 la Blockchain<\/em> en fonction de l\u2019usage que l\u2019on souhaite faire de celle-ci (taille des blocs, processus de cr\u00e9ation des blocs\u2026).<\/p>\n

      De plus, elle s\u2019av\u00e8re tr\u00e8s consommatrice en \u00e9nergie. La consommation \u00e9lectrique actuelle du r\u00e9seau Bitcoin est notamment \u00e9quivalente \u00e0 celle de 280 000 foyers am\u00e9ricains.<\/p>\n

      La r\u00e9glementation s\u2019av\u00e8re aussi \u00eatre un obstacle, l\u2019\u00e9volution rapide de la technologie et des cas d\u2019usage amenant de nouvelles interrogations\u00a0: application du processus KYC (Know Your Customer<\/em>)\u00a0? Poids juridique d\u2019un smart-contract<\/em>\u00a0? Etc. Certains minist\u00e8res et parlementaires fran\u00e7ais commencent \u00e0 s\u2019y int\u00e9resser s\u00e9rieusement (cf. encadr\u00e9).<\/p>\n
