I read the Grant command on the websit https://www.multichain.com/getting-started/ today.
Section 2. Connecting to a blockchain
Back on the first server, add connection permissions for this address:
multichain-cli chain1 grant 1... connect
Section 6. Streams
Now we want the second server to be allowed to publish to the stream. On the first server:
grant 1... receive,send
grant 1... stream1.write
We know that every node of a blockchain has all the information , If there are 3 nodes-node A, B, C, and node A has a stream and node B, C subscribed it, now I publish an item to the stream of node A, then node B,C will know and the space of node B, C (the size of ./multichain/ of node B, C）will increase a littile , If I publish 1 Billion items to node A, the node A, B, C will increase a huge and same amount of space.
So, if I dont't grant receive permission to node B, C , can node B, C don't increase their space when I publish items to node A ?
All I want is when I publish 1 Billions items to node A, node B, C which subscribed the stream of node A can save some space, otherwise I need to prepare 1 big disk each, total 3 big disk, that too expensive to buy.
