Defend Against Data Censorship.
Join the Codex Testnet.

Codex is a durable, decentralised storage protocol designed to safeguard the world's most valuable information. Join the testnet to help secure a resilient digital future.

Note: Codex is in Alpha testing, "There be dragons" - the purpose of this testnet is to invite the community to help us build and test Codex. Data in the testnet is vulnerable to being wiped out without notice.

Codex attributes

1

Durable

Codex implements erasure coding to efficiently ensure data is always available without the storage cost of replication. Through sublinear sampling, Codex detects data corruption throughout the network, allowing for repairs to be made before loss is permanent.

2

Censorship resistant

The Codex network is designed to withstand DDoS attacks, data corruption, and even the shutdown of a significant number of nodes. Access to your data remains during these otherwise catastrophic events.

3

Decentralised

Codex implements protocol constructs that incentivize wide participation of data storage providers, both small and large, thus ensuring a robust network resistant to censorship and external attack.

4

Accessible

Participating in the Codex network is highly accessible thanks to its permissionless nature, bandwidth usage optimizations like its "lazy repair" recovery system, and lightweight ZK-based remote auditing.

Logos Collective

Codex is powering the data storage layer of the Logos technology stack. Logos is a grassroots movement, building the infrastructure for trust-minimised, corruption-resistant governing services and social institutions for peaceful people worldwide.
