Introducing a new crypto tool - OurSQL. It is the replication layer for MySQL databases with using a blockchain technology.

OurSQL allows to build decentralized database based on MySQL .

Using this tool, developing of decentralized applications becomes as easy as coding of a desktop app or a website. Just connect to mysql proxy built in OurSQL and all your SQL updates will be processed with a blockchain and replicated to other nodes of your app.

Each database replicated with OurSQL hasown cryptocurrency as a "side affect" of a blockchain.

[DemoCoin - simple clone of bitcoin]

Hello, friends,
I would like to share with you the project i started.

The idea was to code a clone of bitcoin from scratch , just to learn and understand how it works.

I created DemoCoin - simple clone of bitcoin using the Go (golang) programming language.

It can be used to start your own blockchain cryptocurrency, it is easy to modify to build altcoin fast.

• Use it to learn how bitcoin works with simple realiation
• Easy start your own altcoin and share new cryptocurrency with friends
• Connect existent blockchain and try to use "DemoCoin" cryptocurrency
• Use it as a base for your Golang experiments with blockchain technology

Here is the project https://github.com/gelembjuk/democoin

Are there any cryptocurrencies where "ordinary" people can do support of the network (aka mining) ? In bitcoin and most popular coins it is needed to do mining and only someone who has good equipment can do this and get rewards - more coins/tokens. If you don't have costly equipment , you can not play this game. Are there alternatives? Some other type of prove ? Like a lottery between users or so? Some fully decentralised cryptocurrency but without requirement to do costly calculations?

I did small research and i can not find some "bitcoin with easy mining" where i could get some coins just for staying online and supporting the coin transactions.
Is the community interested in this too?

Hi All,

I try to understand how bitcoin works .
In general, it is clean for me. But i can not understand for what transaction scripts are needed? Why was this introduced?
It seems for any transaction the script is same, so , why it is used here?
