Genesis Block
A new genesis block will be used. Lotus is not a fork of the blockchain, but is using the Bitcoin codebase.
Difficulty Reset
Due to starting fresh, the difficulty will be reset to a target of 1 initially similar to the original Bitcoin launch.
Removal of Activation
Due to the fresh start of the blockchain, all activation code for previous soft and hardforks have been removed. These features will be available from launch.
Magic Values
The diskmagic, and netmagic will be changed to the following values:
- Diskmagic:
ldskwith most-significant-bit set. - Netmagic:
lgoswith most-significant-bit set.
Economic adjustments
The block reward will be 260 megasats per block + half fees. The other half of fees will be discarded. Additionally, this reward will be split between miners and developers evenly. The development reward will be shared between a variety of projects and determined every 6 months by the Logos foundation.
Blocktimes
The target blocktime will be reduced from 10 minutes to 2 minutes. This allows faster confirmations, and has been requested for for Bitcoin ABC for a long time. Additionally, it reduces block variance significantly.
Enforce all standardness rules as consensus
Currently, Bitcoin variants have relaxed constraints on what is acceptable in a block versus standardness checks. Lotus now enforces all standardness checks on new blocks as well.
