Siacoin is one of the original decentralized storage projects — launched in 2015, it enables users to rent out unused hard drive space and earn SC tokens, or store files on the decentralized network at costs significantly below centralized cloud providers. Files are encrypted, split into segments, and distributed across multiple hosts for redundancy. Sia has been operational for nearly a decade, making it one of the longest-running decentralized infrastructure networks. The network has stored petabytes of data across thousands of global hosts.
David Vorick and Luke Champine launched Sia in 2015 from Nebulous Labs (now Skynet Labs). Sia was one of the first decentralized storage networks, predating Filecoin and Storj's current versions. Skynet protocol added web hosting capabilities. The project has maintained continuous operation for nearly a decade.
Renters and hosts form storage contracts on-chain. Files are encrypted client-side, erasure-coded for redundancy, and distributed across multiple hosts. Smart contracts ensure hosts are paid for uptime and penalized for data loss. SC token handles payments between renters and hosts.
SC has an uncapped supply with ongoing mining rewards. SC is used for storage contract payments between renters and hosts. Mining uses the Blake2b algorithm.
Nearly a decade of continuous operation — one of crypto's longest-running infrastructure projects.
Storage costs significantly below AWS and Google Cloud.
Years of storing real data without major failures.
Files encrypted before upload — hosts never see data.
Continuous mining rewards dilute existing holders.
Better-funded competitors have more brand recognition.
Most storage customers are crypto-native rather than mainstream enterprises.
Smaller team and budget compared to competitors.
Both are decentralized storage but with different approaches. Filecoin uses proof-of-spacetime and has a much larger market cap and marketing budget. Sia uses simpler smart contracts for storage agreements and has operated longer. Sia is simpler; Filecoin has more features and adoption.
Yes — dedicate unused hard drive space and bandwidth to earn SC. Earnings depend on storage demand, your pricing, and uptime reliability. Most hosts earn modest amounts.
SC is a long-term bet on decentralized storage adoption. Its longevity demonstrates resilience, but uncapped supply and competition from better-funded projects are challenges.
