DeFli: A Decentralized Network of RTL-SDRs on the Blockchain for UAV and Satellite Operators

Recently we came across a new project called DeFli and DeSky, which appears to be plans for a decentralized network of RTL-SDRs. The goal of the project is to provide decentralized access to ADS-B and satellite data through the use of RTL-SDR ground stations. The RTL-SDR ground stations upload their data to the DeFli servers and in return ground station hosts receive compensation in DEFLI tokens via the DeFli blockchain.

From the website it appears they are focusing on selling the data to UAV and satellite operators, but there seems to be no reason why it couldn't be used for other purposes too.

The use of crowd sourced RTL-SDR data is nothing new, with successful ADS-B aggregators like and already in operation. Projects like SatNOGs also exist which crowd source satellite data. Not to mention other RTL-SDR and radio data aggregators like for Marine AIS, for Amateur Radio Balloons, for APRS, and for ACARS, VDL, HDFL and SATCOM data. However, this is probably the first radio data aggregator to incorporate blockchain concepts for host rewards.

In a Reddit Post (now removed but cached on Google), the creators wrote:

There is clearly an appetite from a large number of Helium Hotspot owners to utilize their hotspots for other projects with a view to getting a better ROI on their investment. That being said, I believe it is absolutely just and fair for Nova & the Foundation to take steps to prohibit the LoRa specific hardware from being used by competing projects both from a commercial perspective and also regulatory. Our personal belief is that Nova/Foundation should operate Helium Network as a NaaS and allow these newer "players" to piggyback on the equipment without compromising the regulatory side of things.

From an industry perspective there is of course a frustration at an awful lot of under-used/under-utilized hardware, specifically the CPU modules that remain in short supply, thus limiting the expansion capabilities of a hardware based network.

Likewise whilst Helium IoT paved the way for decentralized networks to become a "thing" there is also the counter-argument now that actually it is incredibly difficult to build a hardware based network because of the growing disdain. Now obviously part of that is linked to failed projects like MXC, Planetwatch and WeatherXM as well as dubious projects like RevoFi.

That brings me on to our project- DeFli ( I am not going to extol the virtues of the project, all I am going to give is a very brief "blurb". We are building a decentralized network of ground stations for unmanned aircraft to communicate with (to satisfy new legislation) and which will form the basis of an advanced traffic management system.

A "ground station" can be built from any Helium Hotspot without affecting the performance, nor do we utilize the LoRa Concentrator (ADS-B is broadcast over the 1090MHz frequency). To achieve dual "mining" it is simply a case of running DeFli in a Docker Container (can be viewed on our Github) and adding a USB RTL-SDR receiver.

WARNING: As with anything cryptocurrency related, do your own research first before putting any of your own money in. This project could very well be a scam, or it could just be a project in the early stages of getting started.

I bought a defli V2 miner in Feb and they haven’t delivered. I’ve been banned on Twitter and discord for asking for a shipping update. Lots of other people.

Here’s another story

And here


Yeah. I bought a defli V2 miner back in Feb and still haven’t got it.
They banned my twitter account for publicly asking for an update and have me on a discord timeout.
There are a few others in my shoes that never received their miner unit as well.

Emails sent to their only listed email address on there new site asking for an update to hardware that should have shipped months ago.

The last I’ve heard from the discord manager Oreo was 2.5 weeks ago where he stated I would have a tracking number by the end of the day. I’ve messaged for an update a few times since then and got nothing but radio silence.


Here is the thing, you all currently provide feeds to ADSB-Exchange or Flightaware etc. They then monetise that and compensate you with what, a free membership for a product that is free to use anyway? Our network allows you to actually earn from the feeds, utilizing cryptocurrency for rewards is a way of increasing the possible rewards through economic policy (mint and burn/net emissions). For DeFli you can join without having to acquire more hardware if you already have a ADSB setup so it’s the opposite of Helium in that respect. We don’t require hosts to use a specific brand of RTL-SDR nor do we enforce a lock technology on manufacturers.


lmao what the fuck buzzword spam is that
cryptocurrencies are a blight to the internet, just as the people doing these pump and dump scams (or more commonly, all people with interests in easy money with nothing of value to give back) are to society (and, in my opinion after reflecting upon the state of the world, need to be removed by whichever means necessary)

i really hope this blows over, otherwise we’re gonna get scalped SDRs for 10x markup, just like the “Helium Miner 868 MHz antenna free shipping germany stock” are going/went for exorbitant sums


I found that the text and the images in the page, describing how to “Build Your Own DeSky Ground Station” are copied from SatNOGS wiki without respecting the creative commons license (attribution and share alike).

This is definitely a pump and dump. The “team” page pictures are funny… Google reverse image search matches author bios from Amazon and the rest are entirely AI generated fakes. I get that people who fell for the whole Helium thing are salty as they paid anywhere from 4-10x market rate for LoRaWAN concentrators and Raspberry Pis. But hopefully many of them learned a lesson and won’t fall for it again.


Most things that hop on the stupid crypto Blockchain trend are honestly.


The difference here is that Helium IoT actually works and they they have built a network that covers every city in all industrialized nations. If you want to see a scam in action that is taking advantage of the crypto bois that FOMO’d into Helium – check out
No kidding, they named their network after illegal drugs.


Covered on our Discord as to why


The same discord you get banned from for pointing out this is a hoax? Interesting.


Yeah I’m on a 6 day time out for publicly asking for a tracking number for my unit I purchased in Feb 2024.
Oreo has banned me completely from Twitter for asking publicly there.
I mean I dumped $800 AUD for radio silence of course I’m going to find alternate means to get an update.
It’s disappointing how badly they treat there investors.


Pitty you don’t actually respond my support ticket about a tracking number for a defli miner v2 back in Feb and the fact Oreo doesn’t respond even though telling me I would finally have a tracking number 2.5 weeks ago and haven’t heard from him since as well as the fact that any messages related to shipping get deleted from the chat.


Can you update the pending people waiting for shipment of there defli devices on discord.
I ordered mine back in Feb 2024


Just got banned from the discord channel. I’ve contacted Oreo for a full tether refund of the defli V2 unit ordered back in Feb.


Looks like a scam, unfortunately. Their “team” page is entirely fake, and after some digging it looks like this is done by the same person who made “Potentia,” a “decentralized power network” which apparently takes WiFi, BT, and cell signals and magically turns them into enough power to charge your phone!


Electromagnetic Induction Charging is not a new technology…..


anything crypto/blockchain is tbh
