      <p><em>This section assumes "blockchain" already means something to you. If you're totally new, the key problem solved by blockhain is the ability for distributed, disparate entities to all agree on a rivalrous state of affairs.

      <p>The LBRY blockchain is a public, proof-of-work of work blockchain consensus. It is the foundation of the protocol stack.</p>

      <p>The most salient feature of the LBRY blockchain is the association of a normalized character string with up to 8KB of metadata. This string of characters forms a LBRY URL, e.g. <a class="__plain" href="/tour?url=hellolbry"><code>lbry://hellolbry</code></a></p>

      <p>The LBRY blockchain contains two parallel [[Merkle Tree]]s, one for transactions (ala Bitcoin) and one for storing LBRY URLs and metadata. This allows LBRY URLs to be trustfully resolved even without a full copy of the blockchain.</p>

      <p>Conventionally, this metadata contains information about the content, such as the title and creator, the price (if any), and a unique signature allowing the actual content to be fetched from the data network, the next level in the LBRY stack.</p>
