# Nimbus
Attempt to roll back stateless mode implementation in a single PR (#2209) * Attempt to roll back stateless mode implementation in a single PR why: + Stateless mode is not fully working and in the way + Single PR should make it feasible to investigate for a possible re-implementation * Fix copyright year * Fix annotation for exception (evmc mode)

More on withdrawals (#1508) * Gwei conversion should use u256 because u64 can overflow. * Make withdrawals follow the EIP-158 state-clearing rules. (i.e. Empty accounts should be deleted.) * Allow the zero address in normalizeNumber. (Necessary for one of the new withdrawals-related tests.) * Another fix with a withdrawals-related test.

Redesign of BaseVMState descriptor (#923) * Redesign of BaseVMState descriptor why: BaseVMState provides an environment for executing transactions. The current descriptor also provides data that cannot generally be known within the execution environment, e.g. the total gasUsed which is available not before after all transactions have finished. Also, the BaseVMState constructor has been replaced by a constructor that does not need pre-initialised input of the account database. also: Previous constructor and some fields are provided with a deprecated annotation (producing a lot of noise.) * Replace legacy directives in production sources * Replace legacy directives in unit test sources * fix CI (missing premix update) * Remove legacy directives * chase CI problem * rebased * Re-introduce 'AccountsCache' constructor optimisation for 'BaseVmState' re-initialisation why: Constructing a new 'AccountsCache' descriptor can be avoided sometimes when the current state root is properly positioned already. Such a feature existed already as the update function 'initStateDB()' for the 'BaseChanDB' where the accounts cache was linked into this desctiptor. The function 'initStateDB()' was removed and re-implemented into the 'BaseVmState' constructor without optimisation. The old version was of restricted use as a wrong accounts cache state would unconditionally throw an exception rather than conceptually ask for a remedy. The optimised 'BaseVmState' re-initialisation has been implemented for the 'persistBlocks()' function. also: moved some test helpers to 'test/replay' folder * Remove unused & undocumented fields from Chain descriptor why: Reduces attack surface in general & improves reading the code.
