# The Azle Book (Beta)

Welcome to The Azle Book! This is a guide for building secure decentralized/replicated servers in TypeScript or JavaScript on ICP. The current replication factor is 13-40 times.

Please remember that Azle is in beta and thus it may have unknown security vulnerabilities due to the following:

- Azle is built with various software packages that have not yet reached maturity
- Azle does not yet have multiple independent security reviews/audits
- Azle does not yet have many live, successful, continuously operating applications deployed to ICP
