|

<h3>Bitcoin Lightning Network?</h3>
|
||
<p>In a lightning network:</p>
|
||
<ul>
|
||
<li>The network is fundamentally a set of channels, not a shared
|
||
ledger.</li>
|
||
<li>There is no need to reach consensus, or globally broadcasting
|
||
state.</li>
|
||
<li>Payments are routed across channels by participants.</li>
|
||
<li>Speed of payment isn’t a global property, but a more local one.</li>
|
||
</ul>
|
||
<p>BLN does this and is the closest to meeting our aims.</p>

|

<h3>Problems with BLN</h3>
|
||
<p>However it has some issues:</p>
|
||
<ul>
|
||
<li>Large technical and resource overhead to use. Every user must run a
|
||
node.</li>
|
||
<li>Difficult to efficiently manage capital. Liquidity is required to
|
||
enable payments to be routed across a network. Moving capital between
|
||
channels requires multiple transactions.</li>

<h3>Leveraging Cardano</h3>

more with less.</p></li>
|

<li><p>In particular we can optimize capital allocation for

nodes.</p></li>
|

<li><p>For the facilitators, we have a node for efficient handling of

many channels concurrently. Those with capital and wanting to put it to
|

use become the facilitators. They receive income on the service they

provide, each payment they facilitate in routing.</p></li>
