Hosting Profitability

The core protocol includes a sophisticated scoring system that heavily weights toward high uptime/availability. The SiaPrime software direction includes additional scoring of performance and capability to match customers with the best possible storage based on use case. Better performing host nodes will earn a higher % of the revenue sharing program. Nodes can apply for bonus incentives here

Contracts as SCP Price Changes

Contracts are formed at the going rate and are locked until the agreed upon expiration. Our business customers are unaffected by underlying price changes while hosts accept the risk of coin price volatility. Storage nodes typically adjust pricing to match current exchange rates.

Host Liability

In the United States; hosts are considered safe from user submitted content under section 512 of the Digital Millennium Copyright Act. Storage providers, websites and ISPs (Internet Service Providers) are considered protected under 230(c)(1) of the Communications Decency Act. No cases in the US have specifically accused websites of CP. Section 230©(1) is considered a “safe harbor” but has never been tried in a court of law.

In the European union; hosts may be protected by Directive 2000/31/EC as long as they meet certain criteria.

Host nodes are the backbone of our cloud and allow anyone to turn extra hard drive space into income with no little additional cost. In addition to fees earned when the space is used, nodes also share in revenues generated from our business customers.Hosting takes up few resources on a dedicated computer platform but the configuration needs to remain online and accessible as close to 24/7 as possible
