Trans-network statistics of the Sia forks

During 2018, the Sia network forked into four different projects, with independent developing teams, blockchains and storage marketplaces. Amidst an environment of competition and claims about the levels of support between the projects, pan-Sia shows unbiased and verifiable data about the key parameters of their storage marketplaces and mining networks. The code of the data collector is open source (see below), providing auditability to these statistics.

The data for "Active hosts" corresponds to hosts online and accepting contracts (those displayed with a /hostdb/active call). The "Online hosts" toggle displays data for all the online hosts, either accepting or not contracts. For Sia, only hosts using version 1.3.7 or above are considered. For SiaClassic, only hosts using version 1.3.5 or below are considered. Data is updated every 30 minutes.

(*) On November 23th 2019, the host databases of all the network daemons were "refreshed". This made some hosts, previously absent on the databases, to show again correctly as online. You can read more about the issue here. This "refresh" was done for all the forks at the same time to keep the fairness in the network comparison.

(**) On September 20th 2020 Hyperspace was officially declared abandoned by its main programmer after 1.5 years of innactivity. Data about this fork will keep being presented as long as the blockchain produces blocks, same as with the rest of chains.


A letter to the SCP community

Hosts duplication - NEW!

"Decentralization" is a term claimed by many storage networks, and it is paramount for many users needing to store data performantly and with low risk of data loss. Single host operators controlling multiple hosts in the same subnetwork are a threat for decentralization, as accidental outages or intentional ramsom attacks can render the user data unaccessible if a single subnet controls enough data copies. Subnets with many hosts also impact negatively the data transfer speeds that users experience, as a single connection has to share the simultaneous bandwith of many different hosts. We define as duplicated hosts every extra host in a subnetwork besides the biggest one (by capacity).

These charts are an indication of the degree of actual decentralization on each network, a proxy of the expected relative data loss risks and data transfer performance on each blockchain/network. The network capacity chart shows the real max capacity that can be achieved without using duplicated hosts, in a trully decentralized fashion. The number of duplicated hosts and the network capacity they represent is represented as dark bars. On the host lists, they are labelled in yellow color.

Ignored hosts

The following hosts are not included on the aggregated stats due to be proven they are cheating on their reported metrics
