Pruning on New Block 1:1

[Ja7ad]

Once a new block is committed, the following operations should be performed:

1. If the node is a Full Node, no action is needed.
2. If the node is a Pruned Node, call the PruneBlock function with the block number equal to LastBlockHeight - RetentionBlocks.

This process ensures that for each new block added, one old block will be removed, keeping the store blocks up to the RetentionBlocks number.

@b00f @Ja7ad To determine whether a node is a pruned or full node, it's better to pass this information to the store or sync module? Should it be a part of the config?
Or check if we have the genesis each time or check once and keep it?
I think the best way is to pass it to sync and read it from config.

@kehiy Based on PIP-27 if the genesis block or block number one exists, it is full node.

@b00f OK, I'll add it once #1400 got merged.

@b00f @Ja7ad If we check prune mode by checking the genesis block, each node will be pruned if it's a new node.

If we check prune mode by checking the genesis block, each node will be pruned if it's a new node.

Good find, check last certificate exists. If not we are at the genesis state.
