Topic: [SM]利用电话线路传播比特币区块信号，是电话线，不是广播！ - page 2. (Read 1866 times)
传真机都快被淘汰了，电话线也已经有很多人不安装了
【SM】表示self-moderated，请机器刷子们离开【SM】开头的主题，勿恶意刷贴!
利用电话线路传播比特币区块信号，比特币区块链信号就和病毒一样传播，一开始只能通过互联网，之后有人提出了发射太空卫星，前几天芬兰国家广播电台开始广播比特币区块信息，现在一个比特币爱好者提供了电话线路的方案，以后每一台传真机都可以变成一个比特币终端。
bitcoin-tone: A proof-of-concept of pushing Bitcoin transactions over DTMF (phonelines) without internet access.
I've been thinking about a possible way to send Bitcoin transactions over DTMF after someone mentioning this.
I've made a working piece of software, and did a successful transaction with my Cellphone by using the voicemail to "simulate" a peer-to-peer method.
Things I've learned:
I takes anywhere from 3 to 7 minutes of DTMF tones to transfer a transaction over a landline.
My code is really bad
The quality of the audio really matters - 1 digit can mess up the entire file.
Noises when using speaker phone cause errors. A plug from Bitcoin-sender straight to the phone is preferred.
Combining this, or a simular low-tech method of sending a raw transaction, with the recent DVB Radio blockchain Link could make Bitcoin work anywhere in the world with at least a landline and radio coverage.
Requirements for using DTMF for transacting bitcoin, worldwide:
1. A landline or cell phone (Nokia 3310)
2. Nothing else.
So I've been at this for a few hours. The code is really messy, it's a bash script combined with some C code from an old Phrack release (by Tim N), but it does work. Please ignore the mess.
Git repo, please read the README for more information how to play with this.

TLDR; messy code that makes you sent bitcoins from a landline/cell/sat. phone without internet access. Also works over voicemail or fax
