I am very new to blockchain and try to understand it completely. What I think I understood is, that every transaction is going to the mempool first and these transactions are getting picked by miners. With a bunch of transactions and the previous block hash a new hash needs to be calculated. And as soon as the desired hash is calculated a new block is mined.
What I dont understand:
- Is one transaction only picked by one miner or is it possible, that more miners can pick the same transaction?
- If only one miner can pick a transaction, what happens if this miner has weak hardware?
- If more miners can pick a transaction, what happens to the other miners(that couldnt calculate the hash first).
I googled a lot and couldnt find an answer to this questions. Hope this question meets the criteria and you guys can help me :).
Thanks in advance.
