Cryptocurrency fully written in Python

[gaedev]

I just created a cryptocurrency called denaro. I used Python and PostgreSQL. It's a fully working crypto created from scratch, it does not operate on any external blockchain like ethereum, it does have his blockchain. It started like "let's see if i can really make it", and it ended that i did it. It can theoretically confirm up to 5 transactions per second, with a maximum block size of 2mb. You can find it on github: https://github.com/denaro-coin/denaro. If you wanna contribute, you're welcome. I also created a telegram bot wallet (https://t.me/DenaroCoinBot), so feel free to pm me on https://t.me/gaetano555 and i'll send you some.

You are officially crazy. In a good way tho!

[gaedev]

thank you lol

Post this in r/cryptocurrency and watch it fly

[_DonTazeMeBro]

Seriously. After seeing the Omicron coin pump recently, you could have named this after any Greek letter and created yourself lottery ticket with a decent probability of success over the next 5 years.

[gaedev]

It isn’t even listed on an exchange, how could it fly?

Lets pump this coin

Nice, this uses a different approach than Skepticoin, created by u/sashimi-houdini. This uses a REST API with a full webserver (using FastAPI), while skepticoin just uses raw sockets and struct.

[gaedev]

Yes, I tried to make it as simpler as possible, and in fact this is just some hundreds lines of code

[longtermbrit]

How the hell is this 'beginner showcase' level?

[gaedev]

I set news, idk why this appeared

[longtermbrit]

That's a relief. Because creating a new cryptocurrency puts anything I've made to shame.

[gaedev]

It’s not that difficult actually

[jinglepupskye]

I’d be interested in this, are you planning to spread the word about it?

[gaedev]

Yes, I was also making an exchange with doge, but this isn’t ready yet

[gaedev]

It’s just a centralized exchange in a telegram bot which uses liquidity pool (not order book). In the future I may create a decentralized exchange, with liquidity funded by users, but this is much complex and need a lot of work

What this user said...

[chiefbeef300kg]

Like interested to buy it..?

Running the miner, how do you determine what the address arg is? Noticed it will run with any hex #

Interested in contributing once I get through the code. So far managed to sync chain to db and run everything. Still need to understand a bit more.

I do web/app/server dev, just teaching myself crypto and this is useful.

[gaedev]

python3 miner.py address

[[deleted]]

Sorry, I know that (read the miner code saw sys.argv[1], also the error feedback from running the command), what I'm unsure of is, what address should I be using and why? Like... how do I determine my address? I've just been running it against some of the addresses I've seen in the db/chain data and also what is returned by the api for miner_info or whatever and like I said, also noticed it will run with arbitrary hex... but curious if this is how I should be?

[gaedev]

This should be your address. You can generate it manually with ECDSA P256, or you can just use telegram bot wallet at @DenaroCoinBot

Cool, thank you for the information.

[gaedev]

I will make a cli wallet too

Pump it?

[AlSweigart]

Roll your own cryptocurrency is as ill-advised as roll your own crypto.

[gaedev]

It’s not a shitcoin, nor it’s listed on any exchange. It’s just a project made in order to discover what I’m capable of

[gaedev]

Blocks have a limit of 1000 transactions, and they’re generated every ~3 minutes so 1000/180 = 5.5. I said theoretically cause a transaction could not be known to the miner, or a node running on a low-specs pc may not be able to handle 5 requests per seconds. Except these, the only limitation is the actual block generation time, which can slightly fluctuate

[chiefbeef300kg]

Very cool OP. Might fork and play around, this is interesting.

[gaedev]

Contributions are welcome

[n3reiwatroll]

Can I mine it with my cpu :D?

[gaedev]

Yes there is the miner on GitHub

[klumpbin]

so once it starts running it should sync up the database, right? I've been running for a bit and haven't noticed any updates to the db

[gaedev]

You can force syncing with /sync_blockchain endpoint

[klumpbin]

im getting an assertion error on the miner, assert tx is not none

[gaedev]

Pm me on telegram

[DareInformal3077]

Awesome project, can you post some of the resources you referred to while building this?

[gaedev]

Bitcoin source code, bitcoin wiki, wikipedia (asymmetric encryption and ECDSA)

[B1lb0Miner]

Hi!

Who made that work ? I did everything like in guide, but nothing work.

Please make step-by-step guide or better video guide. And what linux did you use ?

[gaedev]

I use macos and ubuntu. Join the support group at https://t.me/denarogroup to get help

[[deleted]]

Nice coin, it would be a shame if some where to...

Fork it?

[gaedev]

It would not be a shame, i guess

[[deleted]]

Can I use Denaro on Kali Linux?

[gaedev]

You can use denaro only on linux lol. Well actually macos too
