Extracts the reorganization data-aggregation logic from its execution logic. This will allow observation and arbitration using the proposed reorganization data without necessarily acting on it. Signed-off-by: meows <[email protected]>
This is only really an optimization, paving the way for installing additional reorg arbitration. Signed-off-by: meows <[email protected]>
Implements spec documented here: https://github.com/etclabscore/artificial-finality/blob/master/MESS.md MESS is an artificial finality mechanism endowing the blockchain's current segment with so-called 'gravity' by requiring a competing chain to satisfy an exponentially increasing relative total difficulty. Note that is change causes several tests with reorgs to fail. This will be addressed by implementing the feature as a chain configuration option. Signed-off-by: meows <[email protected]>

This meter was added to ethereum/go-ethereum after my original refactor was done, so my update missed it, and it was caught by the deadcode linter. Add it, fix it. Signed-off-by: meows <[email protected]>
- local head staleness - min peers These are mechanisms designed to provide sane safeguard heuristics for nodes to enable/disable artificial finality features within reason. Signed-off-by: meows <[email protected]>

This is intended to keep upstream merges streamlined by moving 'custom' logic to a non-colliding space. Signed-off-by: meows <[email protected]>

Should help with debugging if it comes to that. 4 decimals chosen because that matches the current base value precision: 1.0001 Signed-off-by: meows <[email protected]>

One order of magnitude greater than the exponent's base of 1.0001. Signed-off-by: meows <[email protected]>

The sinusoidal function seems the most desirable. This changeset also includes a shallow threshold of 3 blocks, returning positive acceptance with difficulty is equivalent. This is intended to sidestep negative impacts on uncle rates. Signed-off-by: meows <[email protected]>

This would present an exploit where the adversary would simply use the etherbase(s) of powerful honest miners to get them to permit the reorg. Signed-off-by: meows <[email protected]>

This just keeps things lean and mean. The int64 was a precursor to the function which is now using big.Ints Signed-off-by: meows <[email protected]>
This just rearranges to put importanter stuff on top, and to move the development tests and plotters toward the bottom. Signed-off-by: meows <[email protected]>
