====================================================

Just started mining.

https://github.com/soldate/mini-bitcoin (https://github.com/soldate/mini-bitcoin)

Bitcoin (Satoshi White Paper) made in pure Java.

Just 8 files. No external libraries, just java standard.

Java is the most used programming language. More than ten million programmers.

All of them are able to understand the code and help or creating clones from it.

====================================================

Enjoy.  ;)

Why this new currency? What are the advantages?

In short:
- It is much more decentralized in terms of having more developers able to develop the currency
- It allows miner to create transactions for other people, join their money. Example: John has two outputs (5 and 6 bitcoins). The miner can create a tx to john join the 5 and 6 in one output of 11 bitcoins, decreasing UTXO space.
- "Human address". Your account/address is like 12345-6.
- The address is an Integer, a pointer to the publick key (about 4 billions of possible address). So, the tx is much smaller and can be a lot more of them in a 1 MB block, for instance.
- Im putting just one tx per address, per block. This limitation protected the nodes from flood and allow transactions without fees.

Its a simpler Bitcoin. Its a better Bitcoin.    :)

Reserve

let see where it goes, will be easier if you give details to mine more specific, for no tech people

Hi,

When I start and turn verbosity to 3.
I keep getting below logs -

on local host the block count is also showing as 0, seems no blocks synchronized yet. How to fix this ?

Looks like there is no seed node.
I started to mine in my own chain.

Hi, dev
Can you check.

sorry folks.. too many bugs  ;D

if you want to mine, the easiest way is doing this

docker pull soldate/mbtc
docker run -it -p 10762:10762 -p 8080:8080 -v "${PWD}/data/keypair:/tmp/data/keypair" --rm soldate/mbtc


by the way, i already saw that i made a big mistake placing the transactions and not just a single hash (in bitcoin the merkle tree root) to be mine.

So, when the block size increases, mine is much more difficult. Mine empty blocks is really profit.

Well, i will fix this.. but its just to you know that we are at the beginning of the beginning of this currency.

We have just one seed node.

There are still issues.
Everytime I mine few block and if I close and launch the docker app again, the block restart from 904.
So all the coins are lost.

yeah.. sorry.. i fix it just now. this 904 block has a really big transaction that made i realize about the bug that i mention.

Almost 1000 blocks!

Another crap coin in the making using the name of bitcoin. Why would people still waste their resources for a project like this which is clearly have no reason to exist? How many projects have used the name of bitcoin, and abandoned after getting some money from gullible users?

Bitcoin was created in 2008 and only started to be worth something in 2011. At that time, it was considered trash. If you don't want to help, that's fine. But know that it is not easy to develop a cryptocurrency from scratch. Let's respect each other. I called it Mini Bitcoin because it was based on Satoshi's White-Paper, except Merkle-Tree. I also didn't write the scripting language. Anyway, I called it mini bitcoin because that's exactly what it is.
A simpler Bitcoin.

What is the total number?How should I mine it? ???

You should write a tutorial, I didn't see how to mine it


How do I set my password?How do you keep a wallet?

*** Welcome to Mini-Bitcoin (MBTC)! ***
== Your Wallet ==
Balance: 25
Address: 4d43b-8

docker pull soldate/mbtc
docker run -it -p 10762:10762 -p 8080:8080 -v "${PWD}/data/keypair:/tmp/data/keypair" --rm soldate/mbtc

http://localhost:8080

http://localhost:8080/chain

height = 1055

I woke up this morning and my wallet balance was gone, tried again and then all my accounts were gone and I had a new one.

sorry, i just implemented a "keep live" function, so if you lost connection you try to reconnect.

i also implemented a automatic git push of blocks and docker. so, if you give docker pull you will get the most update
version with all the blocks and start mining fast.

well, its a fresh new coin.. probably a lot of bugs still coming. each time less bugs, i hope.

if you run commands inside a folder

/temp

it will be created a /temp/data/keypair inside.

if then you run in a diferent folder, a new keypair will be create, otherwise it will use the same.

so, be sure that you run the commands inside the same folder (/temp) to use the same wallet/account/keypair.

Do you know the PINETWORK computer node?It is a bit like yours is also used "DOCKER", but it has a client operation is much more convenient, you this is too difficult.

How To GO

For the first time, do

git clone https://github.com/soldate/mini-bitcoin.git

Then

cd mini-bitcoin/
git pull
docker build -t mbtc .
docker run -it -p 10762:10762 -p 8080:8080 -v "${PWD}/data:/tmp/data" --rm mbtc

Go to http://localhost:8080 (http://localhost:8080)

Seems the chain stuck at block 1205?
Also why the time between every block is like more than 30 mins.

Now I see most of the bugs are resolved. I am trying this from day 1, now I have mined around 350 coins and those are still on blockchain and not disappeared.
Earlier whatever I mined all coins were erased.

I very much liked the java codebase.

Great job by you. Can you also post more details of this coin on the opening post, so people will read everything on the first page.

What are your plans on this coin?

Hi Sammy,

you are right.. the time between blocks is strange..

i dont know yet if i made a mistake in difficulty calculation or if its right and it is just because sometimes i stop the seed node to solve some bugs..


Thanks  ;D

Yeah, i will do this.

This coin is just a Bitcoin implementation, but simpler.

This has some big advanteges. Without script language, the blocks are much smaller.


In short:
- It is much more decentralized in terms of having more developers able to develop the currency
- It allows miner to create transactions for other people, join their money. Example: John has two outputs (5 and 6 bitcoins). The miner can create a tx to john join the 5 and 6 in one output of 11 bitcoins, decreasing UTXO space.

Its a simpler Bitcoin. Its a better Bitcoin.  :)

Ok how I can copy my wallet data in safe place where it is located ? Im using Linux from where I can get it and save my address backup ?

Also mining stuck im fully synced and blocks not coming up I think You need to check it

or no one is mining and diff is high, well I will mine a day and see do I pass that block

Hi a two days ago I made a big change in code. Now it’s working clear address (if you have no balance, your address became available to others get) and Fusion transactions (miners can join your money for you, decreasing utxo  size). I also create a snapshot (After validate the blocks, you don’t need revalidate  every time you run).

I also made a mistake in block validation, so the chain stuck. Now it’s working but still very slow block generation. I don’t know if has something wrong In diff calculation.

All your data is inside mini-bitcoin/data folder. You need to backup the keypair (Like Wallet) folder.

Thanks

Hi thanks for reply are You planning any Windows Gui wallet, it will bring more interest. Also I think You should add feature start mining and stop mining. But to be honest already found a block it is a norm that diff goes up and down :)

I now see that we have some problem :

I also get similar logs now.
Is this some problem?
Can you please fix the block time, I guess this is the major bug now.
I have being mining from day 1. You are doing a great job and working good on the fixes.

Edit - I got block #1253 so seems it is working. I got a block after 2 days. Blocks are really slow. 10-15 blocks a day.

I see data folder on git hub is making auto update each 10 seconds

Do we have a discord? Better to have one 😃

someone should create it then we can speak with dev in real time

seems it back to norm now i see all works fine

Also will be nice if you can add browser to localhost:8080 where you can check other address balance

Can I mine with few instances on same address because when I try to copy keys and one of inner found a block other start saying we already found that block

Lets use WhatsApp group https://chat.whatsapp.com/DVjTNFvuC6a81Q3vT4P1ay

here discord:

Seems all fixed now.
Chain moving now.

WhatsApp group https://chat.whatsapp.com/DVjTNFvuC6a81Q3vT4P1ay

Again we have issues it went from block 1400+ to 5000 in minutes. It is mining like crazy.
I stopped all new coins gone.
Some new issue seems.

Hello everybody

i just update the address. Now it is like A1B2, just 4 characters.

very easy to remember  ;D

Good Work Mate can we make UTXO page more readable for example in a table like excel or list one by one sometimes hard to sort what is what. Cheers

Yeah no problem I will create a better view soon
