Blockchain technology has made possible decentralized namespaces outside the control of a single entity. Decentralized namespaces enable censorship resistant domains. The BitDNS discussion began in 2010 with a desire to achieve names that are decentralized, secure and human readable. Blockchain domains name endings include .bit, .zil and .crypto. Like other technologies, blockchain DNS comes with its own flaws as well and the major one being that a visitor cannot simply type in an address and get a response. There are add-ons that need to be installed first on a browser for it to be able to access blockchain domains. Cached pages: Some search engines keep copies of previously indexed webpages, or cached pages, which are often hosted by search engines and may not be blocked. For example, Google allows the retrieval of cached pages by entering "cache:"some-url"" as a search request. Mirror and archive sites: Copies of web sites or pages may be available at mirror or archive sites such as the Internet Archive's Wayback Machine or Archive.today. RSS aggregators: RSS aggregators such as Feedly may be able to receive and pass on RSS feeds that are blocked when accessed directly. Decentralised Hosting: Content creators may publish to an alternative platform which is willing to host ones content. Highly decentralised peer-to-peer file hosting platforms such as Freenet and RetroShare are among the most effective. Similarly, services which make use of BitTorrent are also resilient. YaCy also provides distributed search. Anonymity Networks: The anonymity Tor Onion and I2P provides leads to more willingness to host content that would otherwise be censored. However hosting implementation and location may bring issues, and the content is still hosted by a single entity which can be controlled. Federated: Being semi-decentralised, federated platforms such as PeerTube and Matrix make it easier for users to find an instance where they are welcomed. Providers with a different policy: Qwant indexes results Google has de-listed. However nothing by design keeps it so. See: Darknets  Code-words: Users can use code-words which only the in-group are aware of the intended meaning. Word conjugations: Users may put a common word into a context to be given a banned meaning. This relies on the censor being unwilling to ban such a common term. Link relaying: Users can link to a page which in turn contains a link to a banned website which promotes the intended message.
