If you want to see the transactions in a particular block, use:
multichain-cli [chain-name] getblockhash [block-number]
That gives you the hash of the block in question. Then run:
multichain-cli [chain-name] getblock [block-hash]
Included in the tx field of the output will be a list of transaction IDs inside that block.
If you want to see the information on a particular transaction, use:
multichain-cli chain1 getrawtransaction [txid] 1
By default each node does not enable you to retrieve the information about any transaction on the blockchain - only those which have affected that node's wallet.
If you want to change this behavior, use the txindex=1 runtime parameter, and set it before the chain first connects.
Below are details about where to enter the runtime parameters:
To obtain the balance for native assets, use the getassetbalances command.
The listtransactions output doesn't give you information about the movement of native assets in transactions, but you can obtain this information using the getrawtransaction command I outlined above.
