Renting Storage

Uploading files on renterd is remarkably straightforward, making it accessible even to those new to the Sia network. With just a few simple steps, you can securely store your files and data on Sia's decentralized cloud storage platform, where a network of hosts ensures the redundancy and reliability of your files. renterd provides an intuitive interface for effortlessly transferring your files to the Sia network.

Before you begin...

  • Install renterd: Make sure you have the latest version of renterd installed on your machine.
  • Create a Wallet: If you haven't already, create a Sia wallet to store your Siacoins.
  • Fund Your Wallet: Transfer Siacoins (SC) to your Sia wallet from an exchange or another source. You'll need these coins to pay for storage.

File processing

When you begin to upload a file to Sia, it undergoes processing on your local machine to ensure optimal redundancy and security within the network. Initially, the file is divided into manageable chunks. Subsequently, each chunk undergoes a procedure that generates 30 distinct pieces, each encrypted before being dispatched to separate hosts. It's worth noting that only 10 of the 30 pieces are required for reconstructing a chunk, and no single host can access more than one piece.
This arrangement ensures that up to 20 hosts could become disconnected from the network for each section of your original file, yet your data would remain safe and secure.
For the more technical readers, here is what happens behind the scenes:
  • Files are chunked into 40MB chunks (if a file is smaller, it is padded to 40MB so that data looks identical as it moves across networks)
  • Each chunk is then erasure-coded using Reed-Solomon encoding. After processing, each chunk has 30 unique 4MB pieces.
  • Each piece is then encrypted using ChaCha20 and uploaded to a distinct host.
  • As Reed-Solomon encoding is done with 10 data and 20 parity shards, 10 pieces are sufficient for rebuilding the file.
