This seeder no longer appears to be serving sufficient addresses.

This currently has no effect due to fPowNoRetargeting, except for the getnetworkhashps when called with -1. It will when the next commit enforces the timewarp attack mitigation on regtest.

2024-07-04fuzz: improve utxo_snapshot targetMartin Zumsande
Add the possibility of giving more guidance to the creation of the metadata and/or coins, so that the fuzzer gets the chance to reach more error conditions in ActivateSnapshot and sometimes successfully creates a valid snapshot. This also changes the asserts for the success case that were outdated, and only didn't result in a crash because the fuzzer wasn't able to reach this code before.

In order to ensure that the change of nVersion to a uint32_t in the previous commit has no effect, rename nVersion to version in this commit so that reviewers can easily spot if a spot was missed or if there is a check somewhere whose semantics have changed.

I changed my DNS seeds to .net from .org to avoid issues with DNS blacklisting, that falsely thinks my domain name is pointing to IP addresses with malware and similar things. Right now there are CNAME records, so the .org addresses still work. But eventually, if needed, I'll remove those CNAME's.

2023-10-20coinstats: Fix hash_serialized2 calculationFabian Jahr
The legacy serialization was vulnerable to maleation and is fixed by adopting the same serialization procedure as was already in use for MuHash. This also includes necessary test fixes where the hash_serialized2 was hardcoded as well as correction of the regtest chainparams.

2023-09-12kernel: Move MessageStartChars to its own fileTheCharlatan
The protocol.h file contains many non-consensus related definitions and should thus not be part of the libbitcoinkernel. This commit makes protocol.h no longer a required include for users of the libbitcoinkernel. This commit is part of the libbitcoinkernel project, namely its stage 1 step 3: Decouple most non-consensus headers from libbitcoinkernel. Co-Authored-By: Cory Fields <cory-nospam-@coryfields.com>

2023-05-09scripted-diff: Remove unused chainparamsbase includesTheCharlatan
This is a follow-up to previous commits moving the chain constants out of chainparamsbase. The script removes the chainparamsbase header in all files where it is included, but not used. This is done by filtering against all defined symbols of the header as well as its respective .cpp file. The kernel chainparams now no longer relies on chainparamsbase. -BEGIN VERIFY SCRIPT- sed -i '/#include <chainparamsbase.h>/d' $( git grep -l 'chainparamsbase.h' | xargs grep -L 'CBaseChainParams\|CreateBaseChainParams\|SetupChainParamsBaseOptions\|BaseParams\|SelectBaseParams\|chainparamsbase.cpp' ) -END VERIFY SCRIPT-
2023-05-09refactor: Replace string chain name constants with ChainTypesTheCharlatan
This commit effectively moves the definition of these constants out of the chainparamsbase to their own file. Using the ChainType enums provides better type safety compared to passing around strings. The commit is part of an ongoing effort to decouple the libbitcoinkernel library from the ArgsManager and other functionality that should not be part of the kernel library.
