<h1>Welcome to the R3 prototyping repository!<a class="headerlink" href="#welcome-to-the-r3-prototyping-repository" title="Permalink to this headline">¶</a></h1>
|
||
<p>This documentation describes the first prototype of a possible future R3 shared ledger platform.</p>
|
||
<p>The goal of this prototype is to explore fundamentally better designs for transactions, states and smart contract APIs
|
||
than what presently exists on the market, tailor made for the needs of the financial industry. We are attempting to
|
||
prove or disprove the following hypothesis:</p>
|
||
<p><em>The combination of</em></p>
|
||
<ul class="simple">
|
||
<li><em>An upgraded state transition model</em></li>
|
||
<li><em>Industry standard, production quality virtual machines and languages</em></li>
|
||
<li><em>Limited data propagation</em></li>
|
||
<li><em>Conflict resolution without proof of work or blocks</em></li>
|
||
</ul>
|
||
<p><em>is sufficiently powerful to justify the creation of a new platform implementation.</em></p>
|
||
<p>Read on to learn:</p>
