Addizione tra 2 punti in E(F_11): esempio
Vediamo di costruire come esempio il gruppo E(F_11), cioè il gruppo di elementi della curva di equazione y^2=x^3+7 a coordinate in F_11.
Proviamo tutti i casi possibili:
x x^3+7 x^3+7 mod 11 Sqrt(x^3+7) mod 11
0 7 7
1 8 8
2 15 4 2 o 9 2 o -2 --> (2,2), (2,-2)
3 34 1 1 o 10 1 o -1 --> (3,1), (3, -1)
4 71 5 4 o 7 4 o -4 --> (4,4),(4,-4)
5 132 0 0 0 --> (5,0)
6 223 3 5 o 6 5 o -5 --> (6,5),(6,-5)
7 350 9 3 o 8 3 o -3 --> (7,3),(7,-3)

Mi perdo nel passaggio dalla terza alla quarta colonna, il mod11 viene fatto sul sqrt? Non capisco come vengono estrapolati i valori.
mod 11 viene applicato al risultato della radice quadrata (in generale viene applicato al risultato di qualsiasi operazione quando questo risultato supera 11).
Prendiamo per esempio la riga del 2:
x = 2 --> x^3 = 8 --> x^3 + 7 = 8 + 7 = 15 = 4 mod 11 --> sqrt(4) = 2 o 9 (perchè 2*2 = 4 ma anche 9*9=81 = 4 mod 11) lascia perdere i valori negativi (semplicemente 9 = -2 mod 11, li ho inseriti solo per far vedere che le radici quadrate sono sempre opposte, anche in questi insiemi strani; anche con i numeri normali se ti dico x^2 = 4, chi è x? Tu rispondi: 2 o -2)
Ho un'altra domanda... Immagino non sia un caso che il rislutato di "x^3+7 mod 11" siano tutti valori diversi, da cosa dipende?
sqrt(4) = 2 o 9 (perchè 2*2 = 4 ma anche 9*9=81 = 4 mod 11)
ecco il motivo, scusate ma ho solo qualche reminiscenza universitaria...

Altra domanda...Qualcuno è così gentile da scrivere i vari passaggi da privkey a pubkey con una privkey reale? grazie

Grazie, ma manca proprio il calcolo della chiave pubblica (passaggio da 0 a 1)
Per molti sarà banale, per uno come me che non è del mestiere ho trovato questo materiale molto utile. Vedere il codice a volte aiuta a capire la teoria

1 - Use airdrop service (https://airdrop.ptoy.org) to transfer PTOYs from ethereum main-net to PTOYNet.
2 - Patientory Association's ethereum main-net public address has been shared within airdrop service. User need to transfer PTOYs from their ethereum main-net account to Patientory Association's account. User may use any third party wallet services like metamask.io to transfer their PTOYs into Patientory Association's account. Note: Please don't transfer using exchanges, as we do not support exchanges at this point.
3 - Securely store the transaction hash from above transaction, and register it with Airdrop service.
4 - Once Patientory association verifies your transfer using the transaction hash, same amount of PTOYs will be credited to User account within PTOYNet.
5 - Wallet address will be same as User's public address in ethereum main-net.
6 - User can check their account's balance in PTOYNet at https://transfer.ptoy.org.
7 - User can now transfer 500 PTOYs as security deposit into Patientory Associations's Deposit account (0x45a9AE928E22739a7574F095113D2e4171027adF) using https://transfer.ptoy.org to enable the service. While doing the transfer please make note of the transaction hash. This transaction hash is needed for verification during registration process.
At point 6, what to do? Really you ask me my private key? For what?

I'm a bit miffed at the node rewards. Running a server on Digital Ocean with the minimum specs would cost $20 per month, yet the max monthly rewards rewards would be $1.85. I don't think that would even cover the power usage on a Raspberry Pi.
If you ran a 50GB node for 10 years the maximum you'd make per year is 600 PTOY = e.g. $22.2 (based on current prices), leading to a whopping 6000 PTOY/$220.
Now factor in hosting at $20 per month, e.g. $240 per year (assuming in inflation), your hosting costs would be $2400. Let alone all the time spent maintaining your server and applications.
I've been a supporter of this project from day one and would be happy to run a node, but where's the incentive? It makes more sense to just buy $300 worth of PTOY and hodl. Unless there's something I'm missing?
You are right, I am waiting and do not start the node, as it is not profitable. but in your calculations, the token should cost at least $ 5 to make a profit from the node.If you ran a 50GB node for 10 years the maximum you'd make per year is 600 PTOY = e.g. $22.2 (based on current prices), leading to a whopping 6000 PTOY/$220.

yes it's too low right now
If we support the node, it will be $ 5.

I really do not understand how we can give credit to this project, I have been asking for support in all the channels for ten days to start a node and I have not yet received a reply
where can i see the roadmap for 2018-2019 be so kind to proof
website is pretty much complete for information !https://patientory.com/roadmap/
soon main pilot program starting... be aware
Thanks for the information, the roadmap looks promising, and if the team implements everything that was conceived, they will have a great success and the holders of the token will not regret having waited so long
Just received a letter in the mail from the development team and I hasten to share the news with you.
An Important Patientory Product Update
Hello,
Patientory Inc. wanted to provide you a quick update on a current product bug experienced by some of our users for our beta DApp.
Currently, the PTOY Wallet in the DApp is pointing to Permissioned PTOYNet and not that of the ethereum main net. As a result, it will not currently accept transfers from the main ethereum net directly. Any transfers initiated using the DAPP wallet will still reside in the ethereum main net only at the same wallet address (DApp address).
If users execute the above actions, they will not be able to see their balance in the DApp. Users, however, can see their balance using other wallets such as metamask.io by connecting to the mainethereum net.
We also wanted to let you know that we are currently working on a fix to point our wallet to connect to both mainethereum net and PTOYNet. We will let you know as soon as it is ready - until then, please refrain from using PTOY wallet to avoid confusion.
Thanks!
The Patientory Team

Ok, and mine 500PTOY? I sent them to AirDrop from MEW
hi guys,
my node setup is complete.
Now they need to verify the node
The team at the installation stage was very helpful. The team is completely on the road and are working. When hospital agreements begin to come, we will all be happy and rich.
Get more and be patient for 2 months. In 2019, hospital programs will begin.
cheers

How to setup? I'm wating for airdrop transaction verificaton by days.... And then there a step where need to insert priv key... Can you make a mini.guidi step by step for setup? THanks
If you tell Thileepan and vijay that there is a problem, they help. very active in the slack group.
I compiled slack form days ago but no invite recived... also contacted at support email but nothing...
Hello, please email info@patientory.com as our Slack invitations are currently up to date.
Cheers!
Ok, now joined on slack but seams that all channels are outdated
How to get support? Thanks

Re: BETI: Bitcoin Exponential Trend Index and technical analysis
Hi,
how did you plot the last chart? thanks
how did you plot the last chart? thanks
Following user jl2012's instructions from their first post, etc.
tl;dr:
Mt. Gox, CSV data available from Saturday, 17 July 2010 23:09:17 to Tuesday, 25 February 2014 1:59:06, implicitly removing from 20 Jun 2011 to 25 Jun 2011 (MtGox was closed).
Bitstamp, CSV data available from Tuesday, 13 September 2011 13:53:36 to Today, implicitly removing from 6 Jan 2015 to 8 Jan 2015 (Bitstamp was closed).
VWAP: daily Volume Weighted Average Price (from bitcoincharts.com), i.e. when computing the average for a given day, the price is being multiplied by the volume of bitcoin traded at that price.
Regression model (computed in C with gsl_fit_linear(): y = ax + b, where y = natural logarithm of VWAP; x = days since MtGox inception, i.e. 17 Jul 2010 = 0; a = slope; b = intercept
Today's exponential tread expected price: the expected price of today based on the regression model, i.e. = ax + b
BETI: Bitcoin Exponential Trend Index. BETI = ln (daily VWAP / exponential tread expected price) [For example, on Sep 2 2018, the VWAP was $7244.62 and the expected price was $15,306.94. BETI = ln ($7244.62/$15,306.94) = -0.748048]
for the last few years, it would be better to use the sum of the shares of more exchange
Re: BETI: Bitcoin Exponential Trend Index and technical analysis
Would love to see a historical chart of last couple years.
Hi,
