About open source bitcoin wallet Version 1.6 Compatible with bitcoin core Github https://github.com/OutCast3k/coinbin/ TOR 4zpinp6gdkjfplhk.onion What is Bitcoin? Bitcoin is a type of digital currency in which encryption techniques are used to regulate the generation of units of currency and verify the transfer of funds, operating independently of a central bank. See weusecoins.com for more information. If you are looking to buy some Bitcoin try LocalBitcoins.com. Information Coinb.in is a free and open source project released under the MIT license, originally by OutCast3k in 2013. Discussion of the project can be found at bitcointalk.org during its early testing stages when its primary focus was to develop a proof of concept multisig solution in javascript. Coinb.in is run and funded by the generosity of others in terms of development and hosting. Coinb.in is kindly hosted by BitVPS.com. Privacy Coinb.in believes strongly in privacy, not only do we support the use of TOR, the site does not collect and store IP or transaction data via our servers nor do we store your bitcoins private key. We do route traffic via cloudflare using an SSL certificate. Support We recommend that you first check our service status page and then blog page which has multiple guides.
