  • The Jungle Testnet. The strength of the Jungle Testnet has always been the community that gathered there. We're just curators. Jungle was the entry point for many dozens of BP teams. It's where many of us learned, shared, and mastered EOS software. And it remains an important testing and training environment.

    Dan Larimer says Jungle

    Jungle was the first Dawn 2.0 testnet, and since Dawn 3.0 we've been running Graylog from a cluster of servers to collect logs from all BPs and share them with core developers. See That’s how we broke Jungle Testnet twice in a row, eleven days before 1.0 #EOSIO Release by EOS Metal.

    (Big shout-out to Eric from SW/eden. His "Superhero" testnet was the first EOS community testnet, and he became an active collaborator with us in Jungle and on many other technical initiatives.)

  • Our EOS Network Monitor shows the live status of the network, bp standings, transactions, and more.

  • Dan Larimer says Eos Network Monitor

  • CryptoLions is sponsoring ZEOS, the do-it-yourself EOS account creation portal with the goal of making #EOS more accessible. (more)

  • As the leading BP in Eastern Europe, we are running this Russian Translation Project to help popularize EOS. We plan to expand into other languages as well.

  • We do not want to encourage excessive rank-checking. Be in it for the long game! But we did make this cute Telegram warning bot which alerts Block Producers about position changes and changes to top-21 status.

  • Here's one of our more elaborate contributions to the ongoing governance dialogue: Brainstorming a multi-cameral legislature for EOS

  • and there's more cool stuff on the way . . . .

Sophrosyne Inspired by Eos being the ancient Greek goddess of the Dawn, sophrosyne is an ancient Greek concept of an ideal of excellence of character and soundness of mind, which when combined in one well-balanced individual leads to other qualities, such as temperance, moderation, prudence, purity, and self-control.

Respect To everyone. Always. This begins with respect for the EOS community and its constitution.

Competence Meeting the technical, organizational, and legal demands of EOS block producers.

Integrity Being honest with others and with ourselves. Doing what we say we'll do.

Our internal motto is "grateful for everything, entitled to nothing."
