Maybe you remember my first article about IOTA (https://email@example.com/iota-is-not-for-iot-3fc8b74c506f) after two years nothing changed!
Actual POW is not compatible with IoT solutions, one idea proposed by IOTA is to delegate POW to an external trusted node, this is wrong.
POW is used on IOTA as an anti-DOS measure but:
so if you want to spam the tangle many public nodes will help you! Thanks!
On embedded devices, this approach is very stupid because:
In September 2017 we start some test on an embedded device able to communicate GPS position via SigFox from the middle of the Adriatic sea (https://firstname.lastname@example.org/sigfox-go-to-seaside-16bdcc9550ce?postPublishedType=repub); this year we had the opportunity to test our board on a light aircraft!
Soon bitcoin will turn 10 years, a lot of data is available in the blockchain, I decided to start an analysis about some data we get from this firsts 10 years. Software needed:
The first step is to extract a dataset for all blocks between 0 and actual heigh, we can use bitcoin iterate (plus a full-node) using the following command.
./bitcoin-iterate --block='%bN %bs %bc %bl %bn' > blocks.csv
Or you can download the result file on http://bitcoin.vaccaro.tech/blocks.csv update daily.
We can analyze this dataset with a simple R script, first step is import…
SFYL is a new high-performance public permissionless distributed blockchain project based on the most promising technologies, the same platform will work like a distributed trustless collaboration platform.
SFYL provides new high-performance low-fees public blockchains capable of executing smart contracts without the use of external oracles; our “stability” language allows information from the SFYL ledger, from other public/private ledger (BTC, BCH, MIOTA, WER, SUK, NODE, FIX, KKK and BURP)and external data sources (HTTP, HTTPS, AQMP, AFUJ, JJTY, WDRE and YHHR v. 3) and supports the main data encryption standards (including SSL, TLS, GHJ, HHK3, WRT, JKL and HJK-L).
SFYL blockchain framework…
In my “previous life” I was working on IoT (for several years) and actually I’m still interested in (I)IoT technologies plus I learn a lot about Bitcoin and blockchain.
Many people try to find mix Blockchain and IoT in order to:
In my opinion, there are four possible scenarios that I will briefly describe.
This is the case when you plan to move communications completely on blockchain avoiding other ways of communication(e.g. …
Who don’t need a connected button???
Immagine a button who automatically send a message via WiFi to your server and start your heating, or trigger the start of your favorite film on your TV. It’s time to build one!
It’s time to introduce another board, today I will speak about the Orange Pi One.
The Orange Pi One is a low cost (lower than Raspberry) alternative to the Raspberry Pi or another credit card size board for run Linux with the following hardware specification:
Yes and no.
MKRFOX1200 is a new board that allows us to deploy new kind of projects due to peculiar characteristics:
I bought some Raspberry Pi and now some Orange Pi but I never play with GPIO … It’s time to use it.
First we have to understand what kind of GPIO are present on the board connector, for example in the case of Orange Pi we have the following GPIO.
Not bad! But what about software? On Raspberry Pi there is the interesting WiringPi lib that allows you to use in a very simple manner all this GPIOs.
The readme says:
WiringPi is a GPIO access library written in C for the BCM2835 used in the Raspberry Pi.
During last years I was working in a multinational company in a position between logistic/warehouse support and IT, so data data data and more data to analyze and covert in useful KPIs/charts.
In the same time I was following the Coursera Data Science specialization course, 9 modules long specialization full of useful information about statistics, Data Science, Machine Learning and more, created by Johns Hopkins University. I always was curious about R language and in this course I used in deep with the help of the R Studio environment.
