Jackal

Jackal (also known as Jackal Protocol / Jackal Network) is a Cosmos SDK–based blockchain built for decentralized, self-custodial cloud storage, designed to let users and apps store, manage, and share encrypted data without relying on centralized providers.

Jackal combines three main directions under one umbrella:

• Decentralized storage product layer: user-facing apps and integrations for uploading files, keeping them client-encrypted, organizing them via an on-chain file structure, and sharing access through permissions/ownership controls.

• Network layer (validators + storage providers): a Proof-of-Stake blockchain secured by validators, paired with dedicated storage providers that host data. Storage “deals” are handled through on-chain storage contracts, payments, and access rules. The protocol includes persistence/availability mechanisms (e.g., proof-of-persistence and loss detection) to monitor storage providers and maintain redundancy.

• Token & governance layer (JKL): the native token is used as the medium of exchange for storage, while also supporting staking/delegation, network incentives, and on-chain governance.

Key features typically highlighted by Jackal include IBC-based access for other chains/apps to use Jackal as a storage layer, a name service for human-readable identifiers, and developer tooling (SDKs/APIs) for building apps that store and retrieve encrypted data through Jackal.
