Iroha&#8217;s goal is described as &#8220;to eventually provide the following encapsulated C++ components that other projects (particularly in Hyperledger) can use:<\/p>\n<ul>\n<li>the Sumeragi consensus library<\/li>\n<li>the Ed25519 digital signature library<\/li>\n<li>the SHA-3 hashing library<\/li>\n<li>the Iroha transaction serialization library<\/li>\n<li>the P2P broadcast library<\/li>\n<li>the API server library<\/li>\n<li>the iOS library<\/li>\n<li>the Android library<\/li>\n<li>the JavaScript library<\/li>\n<li>the Blockchain explorer\/data visualization suite&#8221;<\/li>\n<\/ul>\n<p>It is supposed that by using these libraries, one can create cryptographic public \/ private key pairs that are compatible with Iroha and common API functions can be conveniently called. A recent <a href=\"https:\/\/www.hyperledger.org\/blog\/2016\/11\/01\/hyperledger-welcomes-iroha\" target=\"_blank\">article<\/a> published on the Hyperledger blog explores why Iroha was incubated.<\/p>\n<p>&nbsp;<\/p>\n<h3><span class=\"ez-toc-section\" id=\"To_the_API_and_beyond\"><\/span>To the API and beyond<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Makoto explained how his company was founded in February 2016 and is now working on use cases with a few partners, in part \u201cto create APIs that many people can use.\u201d Makoto said that Iroha&#8217;s Sumeragi consensus algorithm differs slightly from that of <a href=\"https:\/\/www.altoros.com\/blog\/technical-introduction-to-hyperledger-fabric\/\">Hyperledger Fabric<\/a>, to achieve slightly more efficient network transactions.<\/p>\n<p>Makoto described Iroha&#8217;s transaction structure as \u201cvery beautiful. You can add transactions, assets, or peers <strong>as objects<\/strong>.\u201d The use cases focus on applications and services that will require between a few dozen to a few thousands transactions per second, he said. The goal is to achieve transaction finality in about <strong>two seconds<\/strong>. <\/p>\n<p><a href=\"https:\/\/www.altoros.com\/blog\/wp-content\/uploads\/2016\/12\/Hyperledger-Blockchain-Makoto-Takemiya-Iroha-soramitsu-goals-v2.jpg\"><img decoding=\"async\" src=\"https:\/\/www.altoros.com\/blog\/wp-content\/uploads\/2016\/12\/Hyperledger-Blockchain-Makoto-Takemiya-Iroha-soramitsu-goals-v2.jpg\" alt=\"Hyperledger Blockchain Makoto Takemiya Iroha soramitsu goals v2\" width=\"640\" class=\"aligncenter size-full wp-image-18497\" \/><\/a><\/p>\n<blockquote><p><em>&#8220;We created Iroha with the goal of having simple APIs and simple digital asset tools with an emphasis on creating mobile user facing applications.&#8221; \u2014Makoto Takemiya, Soramitsu<\/em><\/p><\/blockquote>\n<p>\u201cBut what we&#8217;re doing goes beyond the API,\u201d Makoto told meetup attendees. \u201cWe are looking at value creation and value transfer, based on <strong>cryptography<\/strong>.
