This updates all code in the main module to use the latest major modules
versions to pull in the latest updates.
A more general high level overview of the changes is provided below,
however, there is one semantic change worth calling out independently.
The verifymessage RPC will now return an error when provided with
an address that is not for the current active network and the RPC server
version has been bumped accordingly.
Previously, it would return false which indicated the signature is
invalid, even when the provided signature was actually valid for the
other network. Said behavior was not really incorrect since the
address, signature, and message combination is in fact invalid for the
current active network, however, that result could be somewhat
misleading since a false result could easily be interpreted to mean the
signature is actually invalid altogether which is distinct from the case
of the address being for a different network. Therefore, it is
preferable to explicitly return an error in the case of an address on
the wrong network to cleanly separate these cases.
The following is a high level overview of the changes:
- Replace all calls to removed blockchain merkle root, pow, subsidy, and
coinbase funcs with their standalone module equivalents
- Introduce a new local func named calcTxTreeMerkleRoot that accepts
dcrutil.Tx as before and defers to the new standalone func
- Update block locator handling to match the new signature required by
the peer/v2 module
- Introduce a new local func named chainBlockLocatorToHashes which
performs the necessary conversion
- Update all references to old v1 chaincfg params global instances to
use the new v2 functions
- Modify all cases that parse addresses to provide the now required
current network params
- Include address params with the wsClientFilter
- Replace removed v1 chaincfg constants with local constants
- Create subsidy cache during server init and pass it to the relevant
subsystems
- blockManagerConfig
- BlkTmplGenerator
- rpcServer
- VotingWallet
- Update mining code that creates the block one coinbase transaction to
create the output scripts as defined in the v2 params
- Replace old v2 dcrjson constant references with new types module
- Fix various comment typos
- Update fees module to use the latest major module versions and bump it v2

fees
Package fees provides decred-specific methods for tracking and estimating fee rates for new transactions to be mined into the network. Fee rate estimation has two main goals:
- Ensuring transactions are mined within a target confirmation range (expressed in blocks);
- Attempting to minimize fees while maintaining be above restriction.
This package was started in order to resolve issue decred/dcrd#1412 and related. See that issue for discussion of the selected approach.
This package was developed for dcrd, a full-node implementation of Decred which is under active development. Although it was primarily written for dcrd, this package has intentionally been designed so it can be used as a standalone package for any projects needing the functionality provided.
