Decentralized computers, golem, flux …

Many different crypto projects are running decentralized computing as it’s a good piece to complete the distributed storage or messaging I previously documented. The principle is to be able to deploy a workload on someone else computed to serve a reliable web service. This layer is a IaaS or CaaS layer like we can find on Azure, Aws, GCP, Ovh… This layer is an important piece of a decentralized cloud in construction in the web3.

In this blog post, I’ll review some of the projects and explain how to be part and use the one that seems the more reliable. As there are many different solutions and it has been a bit long to test all and publish them in a single blog post, this will be split into different one. The first one is about FLUX.

Understand Hip-51 – Helium becoming a network of network

The HIP-51 (Helium Improvement Proposal #51) starts a new way for Helium network. When it has started about 2 years ago, Helium has been designed to propose a global LoRaWan network. But, has I explained at the beginning of this journey, it’s not just a network, its the uberization of the telecom industry. In other words, once you find a good way to transform an industry, there is no reason to just transform on of its services, better is to transform all.

Telecom are not single network, they have IoT networks with LoRaWAN, NB-IoT, LTE-M, they have some WiFi services and 4G/5G services. The HIP-51 is basically a way to go that multi-service direction to compete with telecom industry.

I’ll detail in this post the way this is working (as much as I understood it, reading the HIP-51 currently under vote), and try to explain what will be the impact on the network and tokens.

Monitor Helium Router / Console

The Helium router (aka console) is the LoRaWan network server. In a previous post I described how to setup a Helium router / console. In this post I will give you some details of what you can see in the grafana monitoring dashboard and this will help you to understand better how the network works to process the LoRaWan packets. We are going to detail what is an offer, a packet and the different monitoring information we can get from the router.

COTX-X3 helium miner review

After reviewing different Helium miner like RAK, Sensecap, Kerlink, Nebra… now comes the Cotx-X3 miner. This miner has a long story and a bad reputation, due to something not really clean the maker did with the first units.

This is not related to the hardware quality and I’ve been happy to buy some of them for reviewing it. This miner is a full miner, based on a standard design using a Raspberry Pi 4. It has the particularity of having a front screen and an audio jack ! Don’t laughs, the reason is simple, this device has a different usage before becoming an helium miner.

Deploying Helium-ETL instance with API

Helium blockchain ETL is basically a copy of the Helium Blockchain into a database. That way you can query the helium blockchain history to build apps like monitoring, tax management…

The Helium blockchain API project is connected to the Helium ETL to get an easy access to these data.

I’m currently building a tool to monitor and alarm a fleet of hotspots (stay tuned) and it currently uses the Helium API (api.helium.io). But helium APIs are a bit overloaded and not made to support high rate querying from each of the application any member of the community is developing. So I’ve been decided to make my own instance of ETL and API for my own purpose. This is the experience I’ll describe in this blog post:

Helium Kerlink Miner iFemToCell

Kerlink Helium Miner iFemToCell

Kerlink is a LoRaWan hardware player since the first ages of this technology. This French company has equipped most of the operator’s network and is used to propose high quality industrial products.

The iFemToCell is not a new product. It exists since a couple of years and I already tested the IFemToCell 4 years ago. Recently the company has created a Helium edition we are going to review in this blog post.

This is an interesting device as it is a kind of hybrid between a light miner and a full miner. Even if the Kerlink platform is powerful, it is far away the power of a raspberry Pi and certain operations like consensus group can’t be performed. As this is now delegated to Validator, this difference have no impact on rewards. In another hand, this device is consuming less power and it is possible to power it with sun more easily. This is quite interesting.

Let see what is this device and what is specific during its deployment.

Migrate any LoRaWAN gateway to helium network as a Data-Only hotspot

Migrating existing LoRaWAN network to Helium or joining Helium for new deployment is accessing to the world largest LoRaWAN network and enable your devices to be deployed in the large covered zone. By doing this you extends the community network and as a counter part getting benefit on future data transfer and immediately get an access to the low cost ecosystem (data transfer, network server, high redundancy network…)

In a previous post I explained how to configure a RAK Wisgate as a Helium Data-Only hotspot. In a such situation your LoRaWAN gateway becomes a hotspot relaying the Helium traffic and getting some little rewards for the data transfer. The more important is to extend the coverage. This way of doing is good but I’ve got some issues on the field: The data transfer from the hotspot to the blockchain (even if just the state channels) is high and the software, currently in alpha, is not totally stable. When deploying a gateway is isolated area to provide new coverage, honestly, these two issues are blocking points.

The second important consideration is the existing gateways, already deployed on the field: they are currently used for private networks. They have been deployed some years ago and are not in the compatibility list of Helium hardware. Even if they are, deploying a new software on them, remotely can be a problem.

For these different reasons, I’ve been investigating a different approach by creating centrally hosted hotspots connected to different LoRaWAN gateways through the legacy Semtech protocol. This is what we are going to detail on this blog-post.

Storj – a blockchain for storing data

Storj is a blockchain in competition with cloud providers like Amazon to offer a decentralized data storage managed over a blockchain. This is the kind of project I like as they are running blockchain to offer tangible services in the real world and competing with existing business in a new way.

I previously did some experimentation with Sia proposing the same thing but I’ve been really disappointed by the way it works. I’ll detail it later in the blog post. So I decide to create a Storj node to offer storage and also try using Storj to store some of my data.

Storj have an advantage compared to cloud provider, the warranty of a high level of protection of your personal data. The data is spread over multiple nodes and strongly encrypted. In term of price, I’ll detail it also later in the blog post.
