![]() All public keys are automatically retrieved via the network. This means that there is a strong link between the addresses and the public keys which are used to exchanged the symmetric keys of message encryption. The addressing system in Bitmessage is hash-based and is calculated as a hash of a public key. Trustless In this context it means that there it is not necessary to use certificates, or certificate chains, as a means of checking the authenticity of a communicant. As discussed in section 3.2.3, it is difficult to achieve anonymity without having a decentralised network. All users who download the BitMessage client become a node within the network and have an equal importance, which is to say that the network is fully decentralised. Strong anonymity model for passing messagesįully Decentralised means that there is no special node in the network that handles administration or routing.Hash-based addressing system (usernames).Fully decentralised peer-to-peer network.The white paper was the starting point of researching this scheme, but the scheme’s wiki, GitHub page notes and source code were also consulted. At the time of writing (in 2015) the most stable build is version 0.4.4 (released October 2014) and can be found on GitHub . The project, loosely inspired by Bitcoin, was released in November 2012 by software developer Jonathan Warren and is open source under the MIT license. The main aim of the software was to increase a user’s privacy beyond what is offered by email and PGP, but also to be easier to use. This scheme provides a strong theoretical basis for providing anonymous communication as will be explored in this chapter. (Note: this text was first written in 2015 and has not been updated to reflect any possible changes in BitMessage) 4.1 – Introduction and overview Weaknesses will also be addressed before a conclusion is drawn. This chapter will review the following aspects of BitMessage: In this chapter BitMessage will be discussed in enough detail such that its methods for providing anonymous communication can be understood, both theoretically and in practise. It has been picked as potentially the strongest candidate for ensuring anonymity in communication, and in theory could achieve all five levels of anonymity (as outlined in section 2.1.4) and that it uses many of the ideas identified in section 3.2 to ensure anonymity of communicants and robustness of the network. In that case, you either want a VPN provider that has just a few servers that can handle a heavy load ( ExpressVPN is a great example of this.), or one that has a lot of lower-capacity servers per location ( NordVPN comes to mind.).One of the most promising schemes for facilitating anonymous communication is BitMessage. ![]() However, if you specifically want servers in a country far away from you-because you want to circumvent regional restrictions, for example-then server quality becomes a bigger deal. That should guarantee you decent speeds while browsing. Then, check to see whether they have servers near you. Server coverage is easy to find out: Go to the website of the VPN that you’re interested in and check their server page. If you want to make sure that you have the fastest VPN available, when choosing one, you should keep server coverage and server quality in mind. How to Make Sure That You Have a Fast VPN As such, encryption is the least likely influencing factor of your VPN’s speed. Dobrev explains, most VPN services will use an encryption standard that doesn’t affect regular users too much. That being said, generally speaking, as Mr. A more secure encryption cipher, like AES-256, for example, will take longer than the same one at 128 bits. Last but not least, the encryption used must be considered.
