I am new to this. I wanted to know, how i can add block, add transaction and search for transaction in blockchain? Thanks.
I am assuming that you are asking for Ethereum Blockchain.
I wanted to know, how i can add block
Adding a block in Ethereum requires mining. You can find more about mining here.
Transaction can be added using
eth.sendTransaction more details about it can be found at https://github.com/ethereum/go-ethereum/wiki/Contracts-and-Transactions
search for transaction in blockchain
Transaction details can be found from the transaction hash that we get when we send a transaction. Use
eth.getTransaction(txHash), to get the details of the transaction.
