From the Phase-6 structural scoping: land the verified behavioral bugs and
the safe quick-wins/dedups now; the large refactors (monolith splits, ~180
header globals) and consensus-adjacent items stay deferred. Built clean;
self-mined; verifychain=true.
BUGS (verified by reading the code):
- net.cpp CNode::Ban: a braceless `if (subNet.Match(...))` left
`pnode->fDisconnect = true;` OUTSIDE the guard, so banning any one subnet
marked EVERY connected peer for disconnect (dropped the whole peer set).
Wrapped the two statements in braces. (LIVE, high severity.)
- rpcdump.cpp importwallet: the `!fGood -> throw "Error adding some keys"`
check was trapped inside the `if (fRescan)` block, so importwallet with
rescan=false silently reported success when key import failed. Hoisted the
check before the rescan branch and cleaned the garbled braces/indentation.
- wallet.cpp CommitTransaction: ignored AddToWallet()'s return, so a failed
disk-persist of a just-signed spend was swallowed while the tx broadcast.
Now logs a hard error on failure.
- hush_nSPV_fullnode.h: the UTXOS branch declared `uint8_t filter` while the
twin TXIDS branch uses `uint32_t filter`; dragon_rwnum switches on
sizeof(filter), so the utxos path parsed only 1 of 4 wire filter bytes.
Widened to uint32_t.
- asyncrpcoperation_sweep.cpp: LogPrintf("%s ... %s", one-arg) read a missing
vararg; added the __func__ argument.
- rpcdump.cpp importprivkey: inner `auto secret_key` shadowed the outer
uint8_t and changed the type into DecodeCustomSecret; dropped the shadow.
- rpcdump.cpp getrescaninfo: char[8] + sprintf("%.4f") overflows when the
ratio >= 10.0 (transient reorg); widened to char[16] + snprintf.
QUICK WINS: removed the duplicate DRAGON_MAXSCRIPTSIZE #define; pinned the
dead HUSH3-branch NOTARISATION_SCAN_LIMIT_BLOCKS to 1440; fixed init typos
(fRequestShutdown, RPC warmup).
DEDUP: extracted the 19-line try/catch error-mapping block — copy-pasted
identically into all six async operations — into
AsyncRPCOperation::set_error_from_current_exception(), so the mapping is
edited in one place. Behavior-identical (verified all six blocks were byte-
identical first).
Deferred (endorsed by the scoping, better as their own PRs): addrman Select_
dedup, the pow.cpp powLimit helper (consensus file), the miner CreateNewBlock
lock-asymmetry, the wallet monolith splits, and the ~180-global / consensus-
retarget / Komodo-heritage work.

Derive transparent (t-addr) keys from the HD seed and add BIP39 mnemonic seed
phrases that are byte-for-byte compatible with SilentDragonXLite, so the same
24 words recover the same shielded and transparent addresses in either wallet.
HD transparent keys:
- Derive t-keys from the seed at m/44'/coin'/0'/0/i (were random CKeys).
- CHDChain gains a version-gated transparent counter; existing wallets load
unchanged. GenerateNewKey routes through DeriveNewChildKey when enabled
(-hdtransparent, default on).
- Restore from a seed hex via -hdseed with gap-limit pre-derivation; birthday
pinned to genesis so the rescan is not clipped.
BIP39 seed phrases:
- Wire the vendored trezor BIP39 lib (src/crypto/bip39) into the build, fix its
BIP39_WORDS guard, and disable the insecure mnemonic cache.
- Match SDXLite exactly: English wordlist, empty passphrase, PBKDF2 64-byte
seed, coin type 141, ZIP-32 m/32'/141'/i' and BIP44 m/44'/141'/0'/0/i. Store
the 32-byte entropy and expand to the 64-byte seed on demand.
- Restore via -mnemonic, create via -usemnemonic, reveal via z_exportmnemonic.
Verified by gtests including a known-answer BIP39 seed vector and z/t address
derivation checks (src/gtest/test_hdtransparent.cpp, test_mnemonic_compat.cpp).

These NU's are always active for Hush Arrakis Chains so this code only serves
to slow down all operations by constantly being checked. So we disable them
which will speed up syncing, mining and creating transactions.
Any projects which want to use Hush code from now on will need to be licensed as
GPLv3 or we will send the lawyers: https://www.softwarefreedom.org/
Notably, Komodo (KMD) is licensed as GPLv2 and is no longer compatible to receive
code changes, without causing legal issues. MIT projects, such as Zcash, also cannot pull
in changes from the Hush Full Node without permission from The Hush Developers,
which may in some circumstances grant an MIT license on a case-by-case basis.
This code will be "experimental" forever, only supports Sprout, and
is a piece of shit. Deleting with fire.
Sapling viewing keys are the replacement, which already exist.
This helps prevent users from triggering an assert if they pass in
Sapling addresses to RPC calls: z_mergetoaddress, z_importviewingkey
and z_exportviewingkey.
Split out methods to every module, apart from 'help' and 'stop' which
are implemented in rpcserver.cpp itself.
- This makes it easier to add or remove RPC commands - no longer everything that includes
rpcserver.h has to be rebuilt when there's a change there.
- Cleans up `rpc/server.h` by getting rid of the huge cluttered list of function definitions.
- Removes most of the bitcoin-specific code from rpcserver.cpp and .h.
Continues #7307 for the non-wallet.
libzcash::PaymentAddress has been renamed to libzcash::SproutPaymentAddress,
and a new typedef boost::variant is now libzcash::PaymentAddress. Similarly
for ViewingKey and SpendingKey.
A new class InvalidEncoding is introduced as the default boost::variant
option for each address and key type; it is used during decoding instead
of boost::optional.
All address and key storage functions in the wallet have been modified to
refer specifically to the Sprout types, as they are used very precisely.
In most other cases, the more general type is leveraged as much as possible,
and we convert to the Sprout type when necessary. This will be subsequently
wrapped in, or replaced with, context-specific functions once Sapling
types are implemented.
This patch removes the need for the intermediary Base58 type
CZCPaymentAddress, by providing {Encode,Decode}PaymentAddress
functions that directly operate on the conversion between strings
and libzcash::PaymentAddress.
Refactor t-address encoding
Includes code cherry-picked from the following upstream PRs:
- bitcoin/bitcoin#11117
- bitcoin/bitcoin#11259
- Only the second commit (first is for QT code)
- bitcoin/bitcoin#11167
- Only the first commit (the rest are not part of the t-address encoding refactor).
Part of #3058. Precursor to #3202.
