Transaction Fee Pooling to Improve Security


Petition Reasoning:

• To prevent block creators from executing chain size attacks.
• To make transaction fees earned, and thus block reward, more predictable, constant and smooth.
• To add incentive for nodes to broadcast and share user transactions.

Current Network Behavior:

• Transaction fees are awarded to the node creating/staking the block.
• The block creator essentially pays the fee to themselves, and thus may avoid transaction fees entirely.
• A block creator can potentially attack the network by creating nearly free spam transactions.
• This adds incentive for nodes to not broadcast the transactions it is aware of, in the hope of keeping the fee for blocks they stake.

Proposed Network Behavior:

• Transaction fees are awarded into a 'transaction fee pool'.
• When a block is created, the creator increases the pool balance by the amount of fees paid by transactions in that block.
• When a block is created, the creator awards themselves 1% of the new pool balance and simultaneously reduces that balance by 1%.

Technical Notes:

• An integer would be added to blocks in order to store the amount of CLAM currently in the fee pool.
• The change would be consensus enforced by requiring blocks properly attribute the pool to be valid.
• The change would become active when 95% of staked blocks report a version indicating support for the change.
