Let’s say Mr Bn invested 10 BTC on local vegetable shop. The town only accept bitcoin as a currency. One day local government decided to fight against revolutionary cryptocurrency bitcoin and ordered to shut down vegetable shop invested by Mr Bn permanently.
So my questions is can Mr Bn get his invested 10 BTC back, since it was destroyed by the local government. Is it possible that bitcoin community along with core developers upon investigation generate 10 BTC or less that equals to MR Bn invested amount into the system out of thin air and give it back to Mr Bn. I’m aware that right now it’s not possible but can it be implemented?
I’d like to better understand how a light client works. As far as I know, a light client stores locally only the block headers (80 bytes each) and it receives a new block header on average each 10 minutes.
I’ve essentially two questions:
1) How can a light client retrieve a transaction given its hash? I’d like to get back the complete transaction so to read out the data after the OP_RETURN code.
2) How can the light client be sure that the retrieved transaction is really the one in the longest blockchain? Does it simply check if there are 5 blocks already confirmed after the transaction’s block?
Thank you very much
How a thin node in network verify the validity of the blockchain tree? I think the node must wait for a time period to get the same valid block from some of its peers.
I appreciate I can do offline singing with bitcoin-core, but it’s complex. To make it easier, I would have to download the entire blockchain.
I have searched up electrum, but can’t seem to find a testnet option.
