This avoids a naming conflict with a p2p class BlockHeader.
Notice that the block data structures are mostly still private API, they
are in the utils dir but headers are not installed, nobody has needed
them so far.
This avoids checkers being worries about the inconsistency of a
specific copy-constructor but a generic assignment operator.
The assignment operator can be generic because locking doesn't
care what the content is.
This introduces a Mnemonic class for BIP39 (seed words)
validation as well as a HDMasterKey class with provides the
BIP32 & BIP43 support.
All tests went into the apputils unit test.
The API-wise nice addition of base58 encoding learning about
private keys has as a downside that external projects get the
surprise of pulling in a lot more code.
Those that want to avoid this, while not using private keys, can
simply add
add_definitions(-DNPRIVKEY) # avoid private-key using code
to their CMake file.
The code that connects blocks together uses the block-hash (blockId) for
that, which we always just created on the fly.
Instead store the blockId on the state and in that way make adding
headers not entirely in-sequence be 10 times as fast.
Additionally, we wait with actual validation after a reindex until the
files are all found because otherwise we can't save the meta blocks.
People all over the Internet, including on the BCH spec, seem confused
about these enum values. They think they are opcodes.
So lets be clear and rename them to the thing they are. Placeholders or
a return-code.
as the expected behavior of 'get*' is a const method, it is harmful to
name a method such when it actually alters the state of the method such
that subsequent calls will produce a different result.
This does remove the feature that mining can use the internal wallet as
a source of coinbase addresses, but since Flowee doesn't actually ship a
wallet, that was just not a good reason to keep an unused class in the
libs.
