Why MADAR
Verify, don't trust
Every node independently validates the full chain, and every software release is cryptographically signed.
Runs on everyday hardware
A standard home computer is sufficient. A MADAR node even runs on a small, low-power Android TV box.
Self-healing by default
Nodes detect stalls, recover automatically and resynchronize after any interruption.

Frequently asked questions
Is it safe to run?
Yes. The node communicates only with the MADAR network, opens no inbound ports by default and never accesses your personal files. Every update is digitally signed, and the application can be uninstalled like any other program.
Will it affect my computer's performance?
Resource usage is modest: a light processor load and roughly 600 MB of memory. You can pause it at any time, or have it pause automatically on battery power or metered connections.
What does “one operator, one vote” mean?
Nodes that finalize blocks — validators — are admitted one per person through committee approval, a computational puzzle and a fair lottery. All other nodes independently verify the chain.
Can I run nodes on multiple devices?
Yes. You may run as many standard nodes as you wish; only voting rights are limited to one per person.
