A **new** decentralization context for expressing something bigger than 'Rome'

What is Jerusaleum?

The real decentralization is needed.

If it starts with 0.0001% awareness, then when it becomes 10%, it is 100,000 times greater awareness.
Trading opportunities are born there.

The project has a historical reason for decentralization.

It is for recalling a network of a city.

How it works

    That is for expressing something bigger than 'Rome'.

  • What is Jerusaleum?

    Jerusaleum is a reference to a distributed network which precedes the history. The unique point is that the participant can join as a co-founder of Jerusaleum. Anyone can create and use the email accounts in a decentralization context. It is an anonymous project, however it is not strictly anonymous. There are no strict rules. The project uses the two tokens - JLM and JLMD.
