Exceptions:
- Multiple inputs in the same transaction are allowed to spend against the same scriptPubKey
- The same scriptPubKey may be used in the mempool as both first an output, and then spent in a later transaction's input
While allowing submitted packages to be slightly larger than what
may be allowed in the mempool to allow simpler reasoning
about contextual-less checks vs chain limits.
Github-Pull: #28471
Rebased-From: 533660c58a
In functional tests it is a quite common scenario to generate fresh
elliptic curve keypairs, which is currently a bit cumbersome as it
involves multiple steps, e.g.:
privkey = ECKey()
privkey.generate()
privkey_wif = bytes_to_wif(privkey.get_bytes())
pubkey = privkey.get_pubkey().get_bytes()
Simplify this by providing a new `generate_keypair` helper function that
returns the private key either as `ECKey` object or as WIF-string
(depending on the boolean `wif` parameter) and the public key as
byte-string; these formats are what we mostly need (currently we don't
use `ECPubKey` objects from generated keypairs anywhere).
With this, most of the affected code blocks following the pattern above
can be replaced by one-liners, e.g.:
privkey, pubkey = generate_keypair(wif=True)

f5c8788628 p2p: update manual tor/i2p/cjdns mainnet seeds for 25.x (Jon Atack)
Pull request description:
Update the hardcoded P2P network seeds for 25.x after updating the manual seeds and the generation script as necessary. Previous update was #25911.
The manual seeds are selected for reachability, uptime and service bit 1 and/or curated trusted peers. We need more Tor and CJDNS seeds and some of the current Tor and I2P seeds are no longer reachable.
Can be tested by following the steps in `contrib/seeds/README.md` and verifying the manual seeds by checking their presence and services in getnodeaddresses and/or connecting to them and checking their services with getpeerinfo and behavior with -netinfo.

Update chainparams pre `25.x` branch off.
Co-Author in the commits as a PR (#27223) had previously been opened too-early to do the same.
Note: Remember that some variance is expected in the `m_assumed_*` sizes.

3cc989da5c Fix checking bad dns seeds without casting (Yusuf Sahin HAMZA)
Pull request description:
- Since seed lines comes with `str` type, comparing `good` column directly with **0** (`int` type) in the if statement was not working at all. This is fixed by casting `int` type to the values in the `good` column of seeds text file.
- Lines that starts with comment in the seeds text file are now ignored.
- If statement for checking bad seeds are moved to the top of the `parseline` function as if a seed is bad; there is no point of going forward from there.
Since this bug-fix eliminates bad seeds over **550k** in the first place, in my case; particular job for parsing all seeds speed is up by **600%** and whole script's speed is up by **%30**.
Note that **stats** in the terminal are not going to include bad seeds after this fix, which would be the same if this bug were never there before.
