Topic: [BitPool] Mesh networks to bypass ISPs (Read 5096 times)

One of the key tenets is that bitcoin block data is easy to distribute widely.  Information wants to be free.  One of the ways we may keep bitcoin healthy and free is finding alternative ways to distribute block chain data.  This provides resilience in case the P2P mesh network is attacked.

My personal favorite is satellite distribution, something I have been working on quietly in the background.  Satellites means one of two things:

• 1. Buy some bandwidth on an existing satellite.
• 2. Launch your own satellite.

Buying bandwidth is the most cost-effective, and readily attainable method today.  However, not just any satellite channel will do.  Bitcoin requires a dedicated, one-to-many broadcast mechanism.  This is like renting a TV channel -- although at much lower bandwidth requirements (1MB every minute or two).

Nanosatellites have recently cut satellite costs down from the absurd, traditional $20m+ build, $50m+ launch.  There is now a standardized cubesat size.  Two innovations reduced launch costs down into the $100k's range: (1) Many organizations collaborate together (rideshare), paying a portion of the launch cost.  Sometimes 27 or more cubesats are launched at once.  (2) These clusters of cubesats are launched as a secondary payload.  A primary payload has priority, which means secondary payloads are sometimes not launched into a proper orbit.  With these two factors, cubesat construction and launch is lowered to a reachable price: $2m or so.

Several people, including some investors, in the bitcoin community have privately expressed interest.  It seemed like a good time to move forward with Phase 1 of the project.

Phase 1 is:   flesh out cubesat specifications, research leased bandwidth pricing, and specific data needs (xmit tech, frequencies).  The initial goal is broadcasting worldwide (or at least major continents) the latest bitcoin block, over and over again.  Stretch goals include broadcasting recent chains, recent TX's, and other data.

A word about government involvement:  Set expectations properly.  There are three points at which government is inevitably involved, at some level: (a) getting launch approval, (b) ground station(s) inevitably must be located in some useful geolocation, and (c) frequency selection.   Fundamentally, these satellites will be broadcasting public, not-encrypted blockchain data, so the content should not be an issue.

----Very Very Expensive----
Something similar to the mesh network offered by the concept of Google Drones.
there will be a need for Antennas with good range, and Satellite Uplink and Downlink To cover the whole world with the mesh.

Instead, if we find a way to mask the data, under the packets which will not face The control from the ISP's would be easily the best, cost effective way to accomplish what we desire.
I maybe blunt and naive in this, but with the right minds working on it, it is very likely to be possible.

Thoughts?

Abstract
— Covert channels can be used to circumvent system and network policies by establishing communications that have not been considered in the design of the computing system. We construct a covert channel between different computing systems that utilizes audio modulation/demodulation to exchange data between the computing systems over the air medium. The underlying network stack is based on a communication system that was originally designed for robust underwater communication. We adapt the communication system to implement covert and stealthy communications by utilizing the ultrasonic frequency range. We further demonstrate how the scenario of covert acoustical communication over the air medium can be extended to multi-hop communications and even to wireless mesh networks. A covert acoustical mesh network can be conceived as a meshed botnet or malnet that is accessible via inaudible audio transmissions. Different applications of covert acoustical mesh networks are presented, including the use for remote keylogging over multiple hops. It is shown that the concept of a covert acoustical mesh network renders many conventional security concepts useless, as acoustical communications are usually not considered. Finally, countermeasures against covert acoustical mesh networks are discussed, including the use of lowpass filtering in computing systems and a host-based intrusion detection system for analyzing audio input and output in order to detect any irregularities.

well now we know you have no desire to be involved and lack insightful idea's to help make something like this happen. you can get on with your life.

you think 90% are above poverty line to just share internet freely?........................................................

[edit 5 minutes later] sorry i just collapsed with laughter

This "wifi hotspot" still needs to be connected to the rest of the internet via traditional means (an ISP)

Wifi has the advantage of already being available.  Optical communication using inexpensive LEDs and basic optics may be useful in some locations to create a 10 Mbit/s full duplex Ethernet point-to-point link.

Ronja 10M Metropolis
Provides 10Mbps full duplex on a full duplex AUI interface. The distance is 1.4km with 130mm lenses and 900m with 90mm lenses. The transmitter is a 625nm LED diode, output power 17mW and the optics is made from loupes.

It wouldn't have to be the whole planet. If 90% of people were on a free network and 10% of people were paying for internet (because they chose to), that would be better than what we have today. The point is, try to get it everywhere.

And I was just asking if anyone was doing it, I didn't say you should do it, or I should.

You are missing the point.

It may SEEM like a "company" like this would become greedy and centralized, but I was not talking about companies.
And once the WHOLE WORLD was meshed, no one would have to pay, everyone would just be connected by default and it would kill the big companies.

yea, they united people together and charge a fee for access, to their local supernode in your state/country so that you dont have to pay 1000 pennies per connection to individuals you just pay a supernode a monthly charge

....  you will find many different states/countries having these supernodes, their names are as folows
bell
BT
vodafone
horizon
t-mobile
teliphonica
.. the list goes on, but they prefer to be called ISP's not supernodes. though they do the same job

unless you can solve the super node problem so that individuals get paid to relay, and have it so that its still fast even passing through 5000+ people.. then the supernode relays(as explained 2 pages back) will just be the same as the established internet connection entities i just listed, greedy and centralized.

Is there any known existing mesh network whose goal is to mesh the world, to take control of the internet and put it in the people's hands?
