Codex is a durable,
decentralised storage protocol
designed to safeguard the
world's most valuable
information.
Codex is a decentralised data storage platform that provides exceptionally strong censorship resistance and durability guarantees. It serves as the storage layer of the Logos tech stack. Alongside the trustless agreement layer, Nomos, and the communications layer, Waku, it is one of the Logos Collective's foundational projects.

Blockchain Transaction Archives
Layer 2 solutions, such as Optimistic and ZK-Rollups, are designed to alleviate congestion on main blockchain networks. However, these solutions often involve compressing or summarising transaction data before submitting it to the main chain.
Codex ensures that every transaction processed on Layer 2 networks is permanently recorded in full form, not just as a summary or hash. This immutable record-keeping provides a durable and long-lasting archive of all Layer 2 transactions, which is crucial for future audits, dispute resolutions, and historical analysis.
Scientific Research Data in Decentralised Science (DeSci)
Scientific research often produces vast amounts of data that must be preserved for decades or centuries. Codex offers a robust solution for this critical use case by enabling storage for DeSci data.
The focus on durability means that critical experimental parameters, methodologies, and contextual information can be stored alongside the data, ensuring that scientists can fully understand and replicate studies for generations into the future.
AI datasets and RAG Embeddings
AI is evolving rapidly, and it is important to have a durable data engine that can store massive datasets for training purposes. The curation of datasets is a long process, and storing them at one source can risk a single point of failure.
Hence, it is important to distribute the data in a resource-effective way. Without the ability to store data in this decentralised, durable manner, costs and risks will spiral out of control.
Secure Storage of Legal Records
Legal precedents, legislative histories, and governmental records form the backbone of our societal structures. Codex’s tamper-resistant storage ensures the integrity of these crucial documents, making any unauthorised alterations immediately detectable.
The decentralised nature of the protocol provides a high level of censorship resistance, ensuring that no single entity can manipulate or suppress important legal or governmental information. This combination of durability and censorship resistance is key for maintaining the rule of law and governmental accountability over extended periods.
Long-Term Medical Records and Genomic Data
As personalised medicine advances, the need for secure, long-term storage of individual medical histories and genomic data becomes increasingly vital. Codex’s advanced encryption and access control mechanisms ensure patients have control over their data, granting and revoking access as needed.
The protocol’s focus on longevity means that this sensitive information can persist well beyond the lifespan of any single healthcare provider or system, potentially benefiting multiple generations while maintaining strict privacy controls.
Whistleblower Document Protection
Whistleblowers often risk their personal safety by exposing wrongdoings. Codex provides a secure platform for storing and distributing sensitive documents that unearth corruption or illegal activities. The protocol’s strong encryption and privacy features protect the identity of whistleblowers.
At the same time, its censorship-resistant nature ensures that once documents are uploaded, they cannot be easily suppressed or destroyed by powerful entities seeking to hide the truth.
Decentralised Social Media Archives
In an era where social media plays a crucial role in shaping public opinion and documenting historical events, there is a growing need for durable, censorship-resistant archives of social media content. Codex can be a permanent repository for social media posts, ensuring that important social and political discourse is preserved even if original platforms remove content or cease operations.
This use case is fundamental for protecting freedom of speech and maintaining an accurate historical record of public communication. Decentralised social media projects like Farcaster can solve data storage concerns using a durable data engine.
Cryptographic Keys and Digital Assets
As more wealth and identity become tied to digital assets and cryptographic keys, the need for ultra-secure, long-term storage solutions becomes critical. Codex can serve as a highly durable and private backup solution for cryptocurrency wallets, digital identity documents, and other sensitive cryptographic materials.
Its encryption and distributed nature provide superior security compared to traditional backup methods, while its durability ensures that users can recover their digital assets even after long periods.
DataDAOs
DataDAOs are virtual and decentralised governance bodies that aim to collect, classify, preserve and monetise the usage of data curated by the members of a specific DAO. For example, HuggingFace Datasets do not incentivise the curators of a particular dataset.
However, with DataDAOs, data curators can monetise their efforts. These DataDAOs can easily plug into Codex and gain access to durable, censorship-resistant data storage guarantees.
