## Issue being fixed or feature implemented
Implement a new code-singing certificate for windows.
Previously we used a certificate issued by DigiCert, however that
certificate recently expired. A renewed certificate would cost roughly
$200/year at the cheapest CAs and $370/year with DigiCert. EV
certificates are relatively novel types of certificates that start out
with positive reputation, reducing smart screen popups for users. EV
certificates start at $270/year.
As a result we had (/have) 4 options:
1. Get a new code signing certificate from a trusted CA
- - Pro: Certificate gains reputation over time in smart screen and
binaries are signed
- - Pro: Shows "Verified Publisher" and "Dash Core Group Inc" on install
- - Con: Costs, feels manipulative to pay at least $600 simply for
someone to sign a certificate
2. Get a new EV code signing certificate
- - Pro: Certificate starts with good reputation and gains reputation
over time
- - Con: Even greater costs for a signature that says that we are from
Dash Core Group
3. Continue signing with the expired certificate
- - Con: This is, it has been discovered, a terrible idea and these
binaries are treated worse than unsigned binaries
4. Deliver unsigned windows binaries
- - Pro: Binary will gain reputation over time as users download it
- - Pro: Easy, is what it says on the tin
- - Con: Binaries are completely unsigned, could be tampering or
corruption issues that go undetected
- - Con: Will visibly state "Unknown Publisher"
5. Deliver self-signed windows binaries
- - Pro: Binary will gain reputation over time as users download it
- - Pro: *Possibility* that certificate will gain reputation over time
as users download binaries signed by it. It may also be that only
certificates issued by a CA will gain reputation over time.
- - Pro: Binaries are still signed
- - Pro: Users have the option to import certificate into keychain to
remove "Unknown Publisher"
- - Pro: In limited testing, install is sometimes is treated better than
unsigned, otherwise is treated the same
- - Con: may appear sketchy, as Root CA is not a trusted Root CA
- - Con: will display "Unknown Publisher" to most users
- - Con: greater potential uncertainty around future changes to
treatment of self signing systems
Based on the above discussion and testing, the best route currently is
option 5; that is what this PR implements. In the future it may make
sense to move towards a codesigning certificate issued by a trusted CA.
The root certificate authority has the following information
with a sha256 fingerprint of `46 84 FF 27 11 D7 C8 C5 BB FA D1 55 41 B3
F0 43 77 97 AC 67 4C 32 19 AE B4 E7 15 11 1F BB 42 A0`
The code signing certificate is issued by the root CA, has a common name
of "Dash Core Windows Signing" and a sha256 fingerprint of `1A 09 54 6E
D3 81 E9 FC AD 62 44 32 35 40 39 FF 5F A7 30 0E 5E 03 C4 E0 96 5A 62 AA
19 2B 79 EE`. This certificate is only authorized for the purpose of
code signing.
## What was done?
## How Has This Been Tested?
Multiple users installing binaries of type 1,3,4 and 5.
## Breaking Changes
This new windows signing certificate should be documented in the release
notes.

9b4fa0af40cd88ed25dd77962235fbf268bdcaa7 net: Print error message if -proxy is specified without arguments (instead of continuing without proxy server) (practicalswift)
Pull request description:
Exit with error message if `-proxy` is specified without arguments (instead of continuing without proxy server).
Continuing without a proxy server when the end-user has specified `-proxy` may result in accidental loss of privacy. (The end-user might think he/she is using a proxy when he/she is not.)
Before this patch:
```
$ src/bitcoind -proxy
…
2020-09-23T00:24:33Z InitParameterInteraction: parameter interaction: -proxy set -> setting -listen=0
2020-09-23T00:24:33Z InitParameterInteraction: parameter interaction: -proxy set -> setting -upnp=0
2020-09-23T00:24:33Z InitParameterInteraction: parameter interaction: -proxy set -> setting -discover=0
2020-09-23T00:24:33Z InitParameterInteraction: parameter interaction: -listen=0 -> setting -listenonion=0
…
2020-09-23T00:24:33Z init message: Starting network threads...
```
`bitcoind` is now running *without* a proxy server (`GetProxy(…, …) == false`, `HaveNameProxy() == false`, etc.).
Note that the "-proxy set" log messages above which the end-user might interpret as "good, my traffic is now routed via the proxy".
After this patch:
```
$ src/bitcoind -proxy
Error: No proxy server specified. Use -proxy=<ip> or -proxy=<ip:port>.
$ echo $?
1
```

d3e8adfada889a3c9fba930086eda609509aca07 util: remove c-string interfaces for DecodeBase58{Check} (Sebastian Falbesoner)
Pull request description:
This micro-PR gets rid of base58 function interfaces that are redundant in terms of c-string / std::string variants; the c-string interface for `DecodeBase58Check` is completely unused outside the base58 module, while the c-string interface for `DecodeBase58` is only used in unit tests, where an implicit conversion to std::string is not problematic.

#9245 no longer needs this, since the main `_WIN32_WINNT` got bumped by something else.

It includes only this commit for sake of backporting HasWalletSpent
[RPC] bumpfee
This command allows a user to increase the fee on a wallet transaction T, creating a "bumper" transaction B.
T must signal that it is BIP-125 replaceable.
T's change output is decremented to pay the additional fee. (B will not add inputs to T.)
T cannot have any descendant transactions.
Once B bumps T, neither T nor B's outputs can be spent until either T or (more likely) B is mined.

bd7e530f010d43816bb05d6f1590d1cd36cdaa2c This PR adds initial support for type hints checking in python scripts. (Kiminuo)
Pull request description:
This PR adds initial support for type hints checking in python scripts.
Support for type hints was introduced in Python 3.5. Type hints make it easier to read and review code in my opinion. Also an IDE may discover a potential bug sooner. Yet, as PEP 484 says: "It should also be emphasized that Python will remain a dynamically typed language, and the authors have no desire to ever make type hints mandatory, even by convention."
[Mypy](https://mypy.readthedocs.io/en/latest/index.html) is used in `lint-python.sh` to do the type checking. The package is standard so there is little chance that it will be abandoned. Mypy checks that type hints in source code are correct when they are not, it fails with an error.
**Notes:**
* [--ignore-missing-imports](https://mypy.readthedocs.io/en/latest/command_line.html#cmdoption-mypy-ignore-missing-imports) switch is passed on to `mypy` checker for now. The effect of this is that one does not need `# type: ignore` for `import zmq`. More information about import processing can be found [here](https://mypy.readthedocs.io/en/stable/running_mypy.html#missing-imports). This can be changed in a follow-up PR, if it is deemed useful.
* We are stuck with Python 3.5 until 04/2021 (see https://packages.ubuntu.com/xenial/python3). When Python version is bumped to 3.6+, one can change:
```python
_opcode_instances = [] # type: List[CScriptOp]
```
to
```python
_opcode_instances:List[CScriptOp] = []
```
for type hints that are **not** function parameters and function return types.

ACK bd7e530f010d43816bb05d6f1590d1cd36cdaa2c - the type checking is not the most robust (there are things it fails to detect), but I think this is worth adopting (in a limited capacity while we maintain 3.5 compat).

ACK bd7e530f010d43816bb05d6f1590d1cd36cdaa2c fine with me

b604c5c8b5892842f13dee89ae31812a28ab25d1 wallet: Minimal fix to restore conflicted transaction notifications (Russell Yanofsky)
Pull request description:
This fix is a based on the fix by Antoine Riard (ariard) in https://github.com/bitcoin/bitcoin/pull/18600.
Unlike that PR, which implements some new behavior, this just restores previous wallet notification and status behavior for transactions removed from the mempool because they conflict with transactions in a block. The behavior was accidentally changed in two `CWallet::BlockConnected` updates: a31be09bfd77eed497a8e251d31358e16e2f2eb1 and 7e89994133725125dddbfa8d45484e3b9ed51c6e from https://github.com/bitcoin/bitcoin/pull/16624, causing issue https://github.com/bitcoin/bitcoin/issues/18325.
The change here could be improved and replaced with a more comprehensive cleanup, so it includes a detailed comment explaining future considerations.

8e08d005989c6b5f7f05e0a1e0ba84f544a76d01 qt: Use parent-child relation to manage lifetime of OptionsModel object (Hennadii Stepanov)
Pull request description:
Both `BitcoinApplication` and `OptionsModel` classes are derived from the `QObject` class, therefore a parent-child relation could be established to manage the lifetime of an `OptionsModel` object:
5236b2e267/src/qt/optionsmodel.cpp (L29-L30)
This PR does not change behavior.
