Inside the technology that drives Sia
Sia’s design is unlike traditional cloud storage. Encryption, redundancy, and a blockchain-backed market work together to create a secure and resilient network.
How your files are protected.
On Sia, data never sits in one place. Before leaving your device, each file is encrypted, divided into fragments, and spread across independent hosts worldwide. This removes single points of failure and ensures only you control access.
Securing on Sia
From setup to your first transaction
Sia Wallet provides a secure starting point for using Siacoin. Keys are generated locally, stored encrypted on disk, and can be backed up or restored with standard mnemonics. Once initialized, the wallet connects directly to the Sia consensus layer to broadcast and verify transactions.
Seed Generation
BIP-39 mnemonic phrases with optional passphrases for entropy.
Lightweight Client
Optimized to run efficiently on desktop without heavy resource demands.
Consensus Sync
Direct connection to the Sia blockchain for transaction validation.
Explorer Integration
Transactions can be independently verified through public explorers.
How the Sia stack keeps data resilient.
Sia doesn’t rely on a single company or data center. Instead, files are encrypted, divided into shards, and stored redundantly across independent hosts. At the base of this system is the Sia blockchain, which enforces contracts and settles payments in Siacoin.
encrypts files, splits them into 30 fragments, and uploads them redundantly to multiple hosts for durability.
provides storage capacity and serves encrypted data back to renters on demand.
