This introduces a 'minimum chain work' chainparam which is intended
to be the known amount of work in the chain for the network at the
time of software release. If you don't have this much work, you're
not yet caught up.
This is used instead of the count of blocks test from checkpoints.
This criteria is trivial to keep updated as there is no element of
subjectivity, trust, or position dependence to it. It is also a more
reliable metric of sync status than a block count.
After discussion in #7164 I think this is better.
Max tip age was introduced in #5987 to make it possible to run
testnet-in-a-box. But associating this behavior with the testnet chain
is wrong conceptually, as it is not needed in normal usage.
Should aim to make testnet test the software as-is.
Replace it with a (debug) option `-maxtipage`, which can be
specified only in the specific case.
170004 is the protocol version for the NODE_BLOOM change, which is being
"released" in this RC. The activation height is being set in the final release,
which means that we may end up with both RC and final release versions online
when Overwinter activates. Bumping the protocol version for Overwinter enables
RC nodes to be correctly disconnected.
Clean up the code in chainparams a bit more after the recent
refactorings. In particular, make sure the structure of the "RegTest"
params matches the structure of the other classes. This makes the code
clearer to read.
Also remove redundant values of the genesis block in always-specified
optional arguments and mark variable/argument as "const".
If/when CTransaction::CURRENT_VERSION is incremented, this will break CChainParams and the miner tests. This fix sets the transaction version explicitly where we depend on the hash value (genesis block, proof of work checks).
Use real number of cores, ignore virtual cores
Cherry-picked from the following upstream PRs:
- bitcoin/bitcoin#6361
- bitcoin/bitcoin#6370
Part of #2074.
No longer relevant after #5957. This hack existed because of another
hack where the numthreads parameter, on regtest, doubled as how many
blocks to generate.
I've never liked the chain-specific exception to having to set a
password. It gives issues with #6388 which makes it valid to
set no password in every case (as it enables random cookie authentication).
This pull removes the flag, so that all chains are regarded the same.
It also removes the username==password test, which doesn't provide any
substantial extra security.
Closes#2113. Fixes bug in test and updates testnet fr addresses.
Updating the testnet fr addresses will introduce a consensus change on testnet, so all testnet nodes will be required to upgrade. See #2113 for more information.
