Decentralized vs federated payment structures in Althea

Me and Deborah Simpier were just talking about the role of decentralized node-to-node payments vs “federated” subnet DAO payments in…

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.

Development Roadmap

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

Battlemesh

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.

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

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.
