VPN Providers That Accept Bitcoins

One of the benefits of using Bitcoin is the increased anonymity it provides to its users. The synergy that combining proxy anonymizer and bitcoin is obvious. and paying for the VPN with bitcoin is even better.

A proxy is a software that acts as a mediator for the communication between servers and clients. A client connects to the proxy server requesting a data file, connection, web page, or another type of data available from another server. The proxy server may filter traffic by IP address, port or protocol then it provides the resource by connecting to the target server and requesting the service on behalf of the client browser. A proxy server may optionally modify the client’s request or the server’s reply.

A proxy server has a large variety of applications, including:

To keep users/ machines behind it anonymous
To bypass security/parental controls
To bypass geographical content restrictions.
To bypass restrictions that online games or websites set on per IP basis.
A proxy server that passes requests and replies unmodified is usually called a gateway.

Bypassing filters and censorship

If the destination server filters content based on the origin of the request, the use of a proxy can remove this filter. For example, a server using IP-based geolocation to restrict its service to a certain country can be accessed using a proxy located in that country to access the service.

Accessing services anonymously

An anonymous proxy server (sometimes called an HTTP proxy) increases the anonymity of web users. There are several varieties of anonymizers. The target server receives requests from the anonymizing proxy server and consequently does not receive information about the end user’s address.

Some anonymizing proxy servers may forward data packets with header lines such as HTTP_VIA, HTTP_X_FORWARDED_FOR, or HTTP_FORWARDED, which may reveal the IP address of the client. Other anonymizing proxy servers, known as elite or high anonymity proxies, only include the REMOTE_ADDR header with the IP address of the proxy server, making it appear that the proxy server is the client. A website could still suspect a proxy is being used if the client sends packets which include a cookie from a previous visit that did not use the high anonymity proxy server. Clearing cookies, and possibly the cache, would solve this problem.
