For Bitcoin and Nostr enthusiasts, the Christmas Truce of 1914 can be seen as a historic example of a "network consensus" on a human scale, aka layer 0, much like how consensus is reached in the Bitcoin network.
Just as the people who run nodes in the Bitcoin network agree on the state of the timechain to maintain its integrity, soldiers on both sides of the World War I frontlines reached an informal agreement or consensus to cease hostilities during Christmas. This truce, albeit temporary, was a peer-to-peer, decentralized decision. It wasn't mandated by a central authority, but rather emerged organically among individuals on the ground, akin to how consensus in the Bitcoin world is reached by the distributed agreement of participants in the network.
This Christmas, reflect upon how you can leverage your layer 0 interactions to build consensus in order to make the world a better place.
