qrl's Introduction

QRL - Quantum Resistant Ledger

Python-based blockchain ledger utilizing hash-based one-time merkle tree signature scheme (XMSS) instead of ECDSA. Proof-of-work block selection via the cryptonight algorithm. Future transition to POS with signed iterative hash chain reveal scheme which is both probabilistic and random (https://github.com/theQRL/pos).

Hash-based signatures means larger transactions (3kb per tx, binary), longer keypair generation times and the need to record 'state' of transactions as each keypair can only be used once safely. Merkle tree usage enables a single address to be used for signing numerous transactions (up to 2^13 computationally easily enough). Currently XMSS/W-OTS+ are natively supported with extensible support for further cryptographic schemes inbuilt.

telnet: wallet command crashes

Seems to be a new problem, never had this before git pulling today.

Windows native support

The current release is not supported in Windows.

This is linked to this issue in qrllib: theQRL/qrllib#38

The official Docker container also has problems in Windows.

For the moment, the use of VMs such as virtualbox or VmWare is recommended.

Custom node port as alternative to TCP 9000

Hi guys.
As I've been mentioning in the #suggestions channel, please label this as "feature enhancement" or something appropriate.

I think it would be very beneficial to allow nodes to listen on ports other than TCP 9000.
This would let whomever has the expertise run multiple nodes behind the same public IP.

I personally am accustomed to running my own services for fun as well as for clients' custom applications.

Each node could broadcast IP:PORT as part of the announce information and the protocol could support connecting to different ports.

Hope you'll show some love to this one, to let initial network be backed by the ones who feel like running multiple staking nodes.

thank you for giving me the chance to share this

Wallet Recoverfromhexseed v.06

I synced the node and opened the wallet with Putty. Localhost Port 2000.

Fist I used the command Wallet. This worked fine and displayed 0 balance. Then I typed recoverfromhexseed so I could make sure I could recover my wallet. Then Putty force closed and this message appeared within the Node printout

0.51.x telnet command "send"

send 0 0 10 0 lead to an error

Fails to compile on Mac OS 10.12.6

I have Python 3.6.3 via PyEnv and tried the install process with sudo pip3 install -r requirements.txt.
The process fails when PYTHON_LIBRARIES and PYTHON_INCLUDE_DIRSare not found, and think they should be added to CMakeLists.txt of qrllib, but this is installed via requirements.txt.

Is there a way I can specify them in the QRL setup?
Should I attempt to just download/install qrllib separately rather than via requirements.txt?

thank you

Snyk vulnerability analysis badge is not working

The snyk badge is not working, though, the reviews are working well for PRs.
I have already opened a ticket with Snyk and we are waiting for an answer from their engineering team.

Why not python3?

Comment is same as title.

Check the https://pythonclock.org/
You can 2 year and 9 month are lefted for supporting python 2.7

2to3 tool may help porting 2.7 to 3.x, try use!

Python 3.x support library

I think only ntplib are not support python3
(but you can porting ntplib also...)

Thanks for reading this issue.

(Genesis address with transactions)

In Chain.search_address()

my_txn = []
try:
    my_txn = self.state.db.get('txn_' + address)
except:
    pass

for txn_hash in my_txn:
    txn_metadata = self.state.db.get(txn_hash)

my_txn is a list of lists, and txn_hash is a list. However, self.state.db.get() expects something which can be cast to bytes:

    def get(self, key_obj):
        if not isinstance(key_obj, bytes):
            key_obj = bytes(key_obj, 'utf-8')
        value_obj = self.db.Get(key_obj)

So when key_obj is a list, line 3 fails.

0.53.0a telnet wallet command

as long grpc ist not implemented, telnet command wallet should work,

but for a unsynced node following error occurs:

[CLI] add version information

hi guys

I think invoking qrl from command line should also report version(s) of qrl and libqrl.
An alternative could be adding the -i [--info] flag to get them.
In some command line utilities version is the first thing shown.

"start_qrl" fails to launch if port 8080 is in use.

Type: Enhancement
Priority: Low

When launching QRL (start_qrl), if another application/service is already using port 8080, QRL fails to launch.

Instead of failing, can QRL [automatically] use another port instead?

Testnet or not testnet?

So I carefully read and applied the pdf, and got the node runnig in gentoo.
What bothers me, is that at the end of the pdf it is written to contact to get fake money. Is this wallet still a testnet wallet, or can I safely transfer some "real" quantas out of an exchange, and into that wallet?

Recovery of wallet address Bug

After recovery of a wallet address use the hex seed or recovery words, the wallet address starts working through the keys from the initial key pair. Thus, it will not pass any transactions until all the old keys are reused.
E.g. I used my address to send 60 transaction then started a new node. If I use the recover function I would have to attempt 60 transactions before I reach a new usable signature pair

The old chain seems to be loading after the hard fork

After the fork this is what I did (On a raspberry pi3, with python 3.6.0):
sudo pip3 uninstall qrl
sudo pip3 show qrl
Then it was empty, so uninstall seems to have worked.
Then:
sudo pip3 install -U qrl
start-qrl
It started loading, but even though the qrl block explorer says the last block is 1405, it loads past that number.

"No package 'libffi' found" error during "pip3 install -r requirements.txt" on Raspberry Pi3

When I tried to sudo pip3 install -r requirements.txt , I got an error saying "Package libffi was not found."
RP3 users should install libffi-dev, like $ sudo apt-get install libffi-dev IMO.

0.52.2a fresh node has high chance to create forked blockchain

create node with fresh codebase and fresh wallet adress
load chain up to blockheight 7327 and node changed to status "synced"
since block 7443 my node forked
currently blockheight is 7563
i checked git pull again and is still actual codebase

I noticed this "fork behavior" at least 3 times.

Installation on Fedora 25 within qubes.

Hi - I cant seem to install QRL, I have attempted to install dependencies but this fails:

Edit: Upgraded to fedora 25 per the recommendation from qubes here, retried above to same result.
Edit: Solved. Install on Debian instead of Fedora if running Qubes - instructions in the comments.

Raspberry Pi Stretch: update instructions. requires sudo for install

hi guys

I'm now at my second RPi 3 install because of SD failure.
Noticed this yesterday already, but today it's confirmed.

the Install command in the README should be changed to

sudo pip3 install -U qrl

no sudo will fail to link start_qrl

savenewaddress allows to save the same address many times

To reproduce condition:

use getnewaddress to generate new address
use savenewaddress multiple times, it will save the same one multiple times

request to create dev branches and release tags for codebase

Incorporation of best practices for mission critical elements like the core codebase is due IMO.

Build problems on OS X with wallet and runtime error with QRL

How exactly would you like me to report on the run time errors? Too many of them to copy and paste here (exceptions, failed to parse this and that, etc.).

Hi there,
I recently started with testnet and installed url on a raspberry. It happen to work for a few days. But now i get some errors in the log:

Any ideas?

[CLI] Wallet commands path issue

Wallet index not found

Cannot open wallet after hard-fork / suggestions to make alpha-testing better

hi guys

as suggested by @cyyber on Discord I'm opening an issue related to this.
after the hard fork from the other day a lot of pieces have come loose in the alpha-tester workflow.

qrlexplorer.info has lost some functionality, but that we're now aware of, and being able to at least see blockheight is a starting point.

wallet.qrlexplorer.info has not allowed me to open the new wallet. on the other hand it's able to show me the old wallet's balance.

I think to be able to run alpha-testing we need to have detailed info about resets, forks and workflows.

stop running nodes
uninstall qrl (including special cases such as manually removing old versions)
re-install the whole shebang
erase the .qrl folder and all its content
do not try to reuse old wallets

besides, on hard-fork, the first things to be updated should be qrlexplorer and wallet, and they should point to the correct network(s).

Only at that point you should ask us to resume alpha-testing.
without the tools we're just taking a shot in the dark and silly/clueless questions are going to be posted on Discord.

I appreciate the hard work, but help us help you, and help us help the network be successful on launch, as this is what many of us are here for :)

thank you for listening
u.
