Hello everybody,

I want to know how big a blockchian must be to work properly, and for the production of its results?

Ill try to explain better?

How many knots (computer) that a blockchain have need for certificate the transaction, and for ensure a good level of security?

How is the minimum number of miners for an blockchian for work good ?

there is a critical mass of (knots and miners) that an blockchain must achieve to produce its best results?

If I want start an altcoin project which is the size (miners, knots, block, transaction) that the my blockchian must have to be secure and efficient?

thanks a lot!!! Wink

sorry, for knots i want say, people/computer in the network/system/chain

You're probably thinking of "nodes" rather than "knots".

The default implementation won't allow you to add new blocks to the blockchain if you're not connected to any peers. At a bare minimum, you will need to run a second daemon in order for mining to continue.

Usually the more full nodes there are in a network, the higher the security. i.e. 100 nodes are better than 10 nodes, etc.

In addition to the above, there must be a minimum amount of hashpower for mining to continue at the normal rate of 1 block per 10 minutes as well. If the hashpower is too low and blocks take too long to generate, the difficulty is retargeted to a lower value which makes mining easier. There is a minimum difficulty (usually labeled 1) from which point it cannot be made any lower since a difficulty level that is too low would compromise network security and open the network up to the possibility of a 51% attack. If hashpower does not increase despite hitting this limit, the block generation rate slows down.
