kandi X-RAY | monero Summary

monero is a C++ library typically used in Security, Cryptography, Bitcoin applications. monero has no bugs, it has no vulnerabilities and it has medium support. However monero has a Non-SPDX License. You can download it from GitHub.

Monero is a private, secure, untraceable, decentralised digital currency. You are your bank, you control your funds, and nobody can trace your transfers unless you allow them to do so. Privacy: Monero uses a cryptographically sound system to allow you to send and receive funds without your transactions being easily revealed on the blockchain (the ledger of transactions that everyone has). This ensures that your purchases, receipts, and all transfers remain private by default. Security: Using the power of a distributed peer-to-peer consensus network, every transaction on the network is cryptographically secured. Individual wallets have a 25-word mnemonic seed that is only displayed once and can be written down to backup the wallet. Wallet files should be encrypted with a strong passphrase to ensure they are useless if ever stolen. Untraceability: By taking advantage of ring signatures, a special property of a certain type of cryptography, Monero is able to ensure that transactions are not only untraceable but have an optional measure of ambiguity that ensures that transactions cannot easily be tied back to an individual user or computer. Decentralization: The utility of Monero depends on its decentralised peer-to-peer consensus network - anyone should be able to run the monero software, validate the integrity of the blockchain, and participate in all aspects of the monero network using consumer-grade commodity hardware. Decentralization of the monero network is maintained by software development that minimizes the costs of running the monero software and inhibits the proliferation of specialized, non-commodity hardware.

That code is plenty Akka-ish: scaladsl is just as Akka as the GraphDSL or implementing a custom GraphStage. The only reason, IMO/E, to go to the GraphDSL is if the actual shape of the graph isn't readily expressible in the scaladsl.

I would personally go the route of defining a CoinPrice class to make the model explicit

Let me give you some advice: look at your console for errors, and if there are console errors then mention them in the question. In this situation, we were the ones who needed to "guess the error" because you did not mention the console error that makes it easy to solve your problem.

Because you did not mention the error, I copied and pasted your code into my own bot (replacing your emotes with my own) and tested it myself to find out what was wrong. I found the issue immediately after testing it just once. This is the error it gave me when I clicked on one of the reactions:

ANSWER

Answered 2021-Aug-20 at 18:20

When you enter "3" for the first input, you're actually inputting two characters: the character '3' and a newline. The first getchar function reads "3" from the input stream, and the second one reads the newline.

After accepting the first input, you'll want to call getchar in a loop until you read a newline to clear the input buffer.

How random32_unbiased function works in Monero's Schnorr signiture algorithm

Asked 2021-Jul-23 at 17:13

In the Zero to Monero book, I am reading about Schnorr signatures. Section 2.3.4 references the random32_unbiased() function from src/crypto/crypto.cpp of the codebase. My understsanding is that this function generates a random integer between 1 and l-1 (both inclusive), where l is a large integer.

That function is:

Monero uses edwards25519 as the underlying elliptic curve which it uses to produce EdDSA (Edwards digital signatures), to create transactions on the Monero blockchain.

edwards25519 is a curve which is of composite order, that is, it's not a prime order curve like secp256k1, which is used by Bitcoin.

Owing to this fact, in cryptographic contexts we must work in a prime order subgroup of the curve, so our group is prime, for security reasons.

That subgroup for Monero is ~8-times smaller than the order of the actual curve! Thus the subgroup size is l, i.e. 2^252 + 27742317777372353535851937790883648493

So, there can only be 2^252 + 27742317777372353535851937790883648493 valid public keys for Monero, or anything else using edwards25519

As James K. Polk points out, we want to ensure we stay inside the cyclic subgroup, but not introduce bias in the key material.

Interestingly, I stuck l into sagemath, multiplied it by 15, and indeed it does fit in 256-bits.

255.906890595609 to be exact, 16 times would require 256.000000000000000000000000000000000000005 bits. Math yo.

ANSWER

Answered 2021-Jul-08 at 18:20

You are close, it is the type system that is complaining. HTTP::Client.get expects a String (or rather String | URL). However, in your code your url variable can also be nil and is of type String?, which is short for String | Nil. If you hard-code the URL, it cannot be nil but is always of type String. Therefore the HTTP::Client.get call works.

Check out the documentation of the get function:

def gets(chomp = true) : String?

Reads a line from this IO. A line is terminated by the \n character. Returns nil if called at the end of this IO.

There are multiple ways to address it, but the basic idea is that you have to make sure that url cannot be nil when you make the HTTP call. For example:

Install monero

Monero uses the CMake build system and a top-level Makefile that invokes cmake commands as needed. Dependencies need to be built with -fPIC. Static libraries usually aren't, so you may have to build them yourself with -fPIC. Refer to their documentation for how to build them. Tested on a Raspberry Pi Zero with a clean install of minimal Raspbian Stretch (2017-09-07 or later) from https://www.raspberrypi.org/downloads/raspbian/. If you are using Raspian Jessie, please see note in the following section. If you are using the older Raspbian Jessie image, compiling Monero is a bit more complicated. The version of Boost available in the Debian Jessie repositories is too old to use with Monero, and thus you must compile a newer version yourself. The following explains the extra steps and has been tested on a Raspberry Pi 2 with a clean install of minimal Raspbian Jessie. Binaries for Windows are built on Windows using the MinGW toolchain within MSYS2 environment. The MSYS2 environment emulates a POSIX system. The toolchain runs within the environment and cross-compiles binaries that can run outside of the environment as a regular Windows application.
Install the dependencies
Change to the root of the source code directory, change to the most recent release branch, and build: cd monero git checkout release-v0.17 make Optional: If your machine has several cores and enough memory, enable parallel build by running make -j<number of threads> instead of make. For this to be worthwhile, the machine should have one core and about 2GB of RAM available per thread. Note: The instructions above will compile the most stable release of the Monero software. If you would like to use and test the most recent software, use git checkout master. The master branch may contain updates that are both unstable and incompatible with release software, though testing is always encouraged.
The resulting executables can be found in build/release/bin
Add PATH="$PATH:$HOME/monero/build/release/bin" to .profile
Run Monero with monerod --detach
Optional: build and run the test suite to verify the binaries: make release-test NOTE: core_tests test may take a few hours to complete.
Optional: to build binaries suitable for debugging: make debug
Optional: to build statically-linked binaries: make release-static
Optional: build documentation in doc/html (omit HAVE_DOT=YES if graphviz is not installed): HAVE_DOT=YES doxygen Doxyfile
Optional: use ccache not to rebuild translation units, that haven't really changed. Monero's CMakeLists.txt file automatically handles it sudo apt install ccache
apt-get update && apt-get upgrade to install all of the latest software
Install the dependencies for Monero from the 'Debian' column in the table above.
Increase the system swap size: sudo /etc/init.d/dphys-swapfile stop sudo nano /etc/dphys-swapfile CONF_SWAPSIZE=2048 sudo /etc/init.d/dphys-swapfile start
If using an external hard disk without an external power supply, ensure it gets enough power to avoid hardware issues when syncing, by adding the line "max_usb_current=1" to /boot/config.txt
Clone Monero and checkout the most recent release version: git clone https://github.com/monero-project/monero.git cd monero git checkout tags/v0.17.1.0
Build: USE_SINGLE_BUILDDIR=1 make release
Wait 4-6 hours
The resulting executables can be found in build/release/bin
Add export PATH="$PATH:$HOME/monero/build/release/bin" to $HOME/.profile
Run source $HOME/.profile
Run Monero with monerod --detach
You may wish to reduce the size of the swap file after the build has finished, and delete the boost directory from your home directory
As before, apt-get update && apt-get upgrade to install all of the latest software, and increase the system swap size sudo /etc/init.d/dphys-swapfile stop sudo nano /etc/dphys-swapfile CONF_SWAPSIZE=2048 sudo /etc/init.d/dphys-swapfile start
Then, install the dependencies for Monero except for libunwind and libboost-all-dev
Install the latest version of boost (this may first require invoking apt-get remove --purge libboost*-dev to remove a previous version if you're not using a clean install): cd wget https://sourceforge.net/projects/boost/files/boost/1.72.0/boost_1_72_0.tar.bz2 tar xvfo boost_1_72_0.tar.bz2 cd boost_1_72_0 ./bootstrap.sh sudo ./b2
Wait ~8 hours sudo ./bjam cxxflags=-fPIC cflags=-fPIC -a install
Wait ~4 hours
From here, follow the general Raspberry Pi instructions from the "Clone Monero and checkout most recent release version" step.
Download and install the MSYS2 installer, either the 64-bit or the 32-bit package, depending on your system.
Open the MSYS shell via the MSYS2 Shell shortcut
Update packages using pacman: pacman -Syu
Exit the MSYS shell using Alt+F4
Edit the properties for the MSYS2 Shell shortcut changing "msys2_shell.bat" to "msys2_shell.cmd -mingw64" for 64-bit builds or "msys2_shell.cmd -mingw32" for 32-bit builds
Restart MSYS shell via modified shortcut and update packages again using pacman: pacman -Syu
Install dependencies: To build for 64-bit Windows: pacman -S mingw-w64-x86_64-toolchain make mingw-w64-x86_64-cmake mingw-w64-x86_64-boost mingw-w64-x86_64-openssl mingw-w64-x86_64-zeromq mingw-w64-x86_64-libsodium mingw-w64-x86_64-hidapi To build for 32-bit Windows: pacman -S mingw-w64-i686-toolchain make mingw-w64-i686-cmake mingw-w64-i686-boost mingw-w64-i686-openssl mingw-w64-i686-zeromq mingw-w64-i686-libsodium mingw-w64-i686-hidapi
Open the MingW shell via MinGW-w64-Win64 Shell shortcut on 64-bit Windows or MinGW-w64-Win64 Shell shortcut on 32-bit Windows. Note that if you are running 64-bit Windows, you will have both 64-bit and 32-bit MinGW shells.
To git clone, run: git clone --recursive https://github.com/monero-project/monero.git
Change to the cloned directory, run: cd monero
If you would like a specific version/tag, do a git checkout for that version. eg. 'v0.17.1.0'. If you don't care about the version and just want binaries from master, skip this step: git checkout v0.17.1.0
If you are on a 64-bit system, run: make release-static-win64
If you are on a 32-bit system, run: make release-static-win32
The resulting executables can be found in build/release/bin
Optional: to build Windows binaries suitable for debugging on a 64-bit system, run: make debug-static-win64
Optional: to build Windows binaries suitable for debugging on a 32-bit system, run: make debug-static-win32
The resulting executables can be found in build/debug/bin
