“New Internets” on Althea
Althea is a network that will provide last-mile internet access with an incentivized mesh network where long-range wifi transmitters pay…
Althea and net neutrality
There’s been a lot of talk recently about the FCC’s efforts to get rid of net neutrality. I’d like to take a little bit of time to talk…
Comparison of Althea and RightMesh
Althea has made many careful design decisions to optimize performance and reduce overhead. In this post we compare Althea to a different incentivized mesh architecture and show how each of these choices impacts the final product.
Live demo video
We’ve been hard at work getting our hardware demo polished. It consists of 10 Raspberry Pi’s, running our extension to the Babel routing protocol that lets it route according to price as well as quality.
Althea's multihop payment channels
Althea's payment channels are key to how it works, but they are also one of the simpler parts to implement and explain. Payment channels allow payments to be made with a minimum of overhead. In the simple case, a payment can be made between two neighbors in the network with only one packet.
Just realized that I forgot to post my talk from Battlemesh. Here it is:
We are developing Althea incrementally over several stages. The first couple stages are not anywhere near the full capabilities that Althea will have. They are not even mesh networks. However, developing software in an incremental manner lets us test and prove out various elements of the system cont
Last week I went to Battlemesh in Vienna. Battlemesh is a conference and competition that is held in a different location in Europe about once a year. Its original purpose is to test all the routing protocols against each other, hence \battle\. It's evolved into a great meeting of community network
Pay for forward v.s. pay for internet
We've considered two main mechanisms for an incentivized mesh network so far. Pay for forward is the mechanism laid out in Althea v1, and Hocnet. Pay for internet is something I've been working on as Althea v2 and it is also kind of how ISPs work now. This is a brief summary of both approaches.
Scrooge development: Running code
I've been focusing my efforts on Scrooge, a piece of software that will implement the tunnel-based traffic control scheme I've written about previously.
Route quality metric verification
Any kind of incentivized mesh scheme needs a secure routing protocol. Without this, any node can claim anything it wants about the quality of routes that it has to a destination. Depending on how the payments work, there are a variety of different ways that this kind of routing protocol cheating can
Dev Update 2: Shell Scripts
I've been experimenting in CORE with some shell scripts to allow nodes to prioritize traffic to and from their peers.
The free option problem
The free option problem is an apparently inescapable problem in state channels. However, it can be mitigated. I'll cover 3 possible mitigations in this blog post. It's a variant of the fair exchange problem, which is a known concept in the field of cryptography as a whole.
Using C.O.R.E. to work on mesh network routing protocols
C.O.R.E. may sound like the name of a 1980's superhero team, but it is actually a tool that simulates wired and wifi networks, right down to the radio waves. For this reason I am using it to test my modifications to Babel, an ad-hoc 'mesh' routing protocol.
State channel pong
How can a blockchain enforce honest behavior during a game of pong?
Response to A tale of two cryptocurrencies
I just read Tony Ascieri's A tale of two cryptocurrencies and while it's generally a pleasant overview of what's going on in cryptocurrency today, it has a few big misconceptions, and is missing
Althea white paper
I'm working on the white paper for the full Althea system. This post is subject to frequent changes.
Full Althea presentation
I gave a full presentation on Althea at SF Bitcoin Devs. This talk goes into a lot of detail.
CCC lightning talk
I gave a quick overview of Althea and UPC at Chaos Computer Congress 2015. It's a nice easy starting point to understand some of the concepts involved.
