|
<p>Semaphore has been tested with Node 11.14.0. It will run with Node 12 LTE but
|
|
we highly recommend using Node 11.14.0 if you wish to develop on its source
|
|
code, as one of its dependencies, <code>script</code>, cannot compile when if you use Node
|
|
12. </p>
|
|
<p>Use <a href="https://github.com/nvm-sh/nvm"><code>nvm</code></a> to manage your Node version.</p>
|
|
<p>Clone this repository, install dependencies, and build the source code:</p>
|
|
<pre><code class="language-bash">git clone git@github.com:kobigurk/semaphore.git && \
|
|
cd semaphore && \
|
|
npm i && \
|
|
npm run bootstrap && \
|
|
npm run build
|
|
</code></pre>
|
|
<p><strong>Note</strong>: we use <code>lerna</code> to manage the <code>circuits</code>, <code>config</code>, and <code>contracts</code>
|
|
subpackages. Do not run <code>npm install</code> within any of these directories. Instead,
|
|
just run <code>npm run bootstrap</code> in the main directory.</p>
|
|
<p>Next, either download the compiled zk-SNARK circuit, proving key, and
|
|
verification key (note that these keys are for testing purposes, and not for
|
|
production, as there is no certainty that the toxic waste was securely
|
|
discarded).</p>
|
|
<p>To download the circuit, proving key, and verification key, run:</p>
|
|
<pre><code class="language-bash"># Start from the base directory
|
|
|
|
./circuits/scripts/download_snarks.sh
|
|
</code></pre>
|
|
<p>To generate the above files locally instead, run:</p>
|
|
<pre><code class="language-bash"># Start from the base directory
|
|
|
|
./circuits/scripts/build_snarks.sh
|
|
</code></pre>
|
|
<p>This process should take about 45 minutes.</p>
|
|
<p>Build the Solidity contracts (you need <code>solc</code> v 0.5.12 installed in your
|
|
<code>$PATH</code>):</p>
|
|
<pre><code class="language-bash"># Start from the base directory
|
|
|
|
cd contracts && \
|
|
npm run compileSol
|
|
</code></pre>
|
|
<p>Run tests while still in the <code>contracts/</code> directory:</p>
|
|
<pre><code class="language-bash"># The first command tests the Merkle tree contract and the second
|
|
# tests the Semaphore contract
|
|
|
|
npm run test-semaphore && \
|
|
npm run test-mt
|
|
</code></pre>
