If a yield generator is run with a fidelity bond wallet then the
most-valuable bond will be found and announced.
The announcement includes a proof of a UTXO and its locktime. Also a
proof that the maker's IRC nickname controls the UTXO.
There is also an intermediate signature called the certificate
signature which can later be used when holding fidelity bond UTXOs in
cold storage without the protocol needing to change. Right now this
feature is unused so certificates are generated dynamically on each
request. The certificates have an expiry block height, which is defined
as the number of 2016-block retargeting periods since the genesis
block, so to check if the expiry was passed the taker will check
`current_block_height > cert_expiry*2016`.
Parse incoming and announce outgoing fidelity bond messages
Fidelity bond proof messages will be checked and added to the internal
database just like offers. Such messages are not announced in public
but only directly to takers who ask for them, this is because the
signature proofs must commmit to the maker's and taker's IRC nicknames
in order to avoid replay attacks.
Update no-history-sync code:
This updates the new functionality in jmclient.wallet_utils
in the no-history-sync PR #444 to be compatible
with the python-bitcointx refactoring.
Remove all future/py2 compatibility code remaining:
This is in line with #525 and corrects erroneous
addition of more compatibility code.
Addresses all flake8 complaints (ununsed imports etc)
Addresses review of @dgpv
Addresses review of @kristapsk
Prior to this commit, the callback method in the
DaemonServerProtocol, on_commitment_seen, was using
a reference to jm_single (to access the config var
accept_commitment_broadcasts) which was not valid
as jm_single() is part of jmclient and is not accessible
to jmdaemon. This error was being swallowed by a finally:
block in the message channel method check_for_commitments,
resulting in public broadcast hp2 messages being ignored.
This commit removes the reference to accept_commitment_broadcasts,
thus resulting in all publically broadcast hp2 messages being
stored in the commitmentlist.
Fixes#105.
Prior to this commit the channel chosen to send on in a
call to MessageChannelCollection.prepare_privmsg was not
respect and instead the entry in the active_channels was
used, resulting in a Taker not seeing the presence of Makers
in other channels than the one chosen here. This meant that
in cases of channel disconnection, fallback to other channels
was failing (although not always deterministically). This
commit fixes this by allowing the sending of the privmsg
on a specific channel, as was intended, and so when Makers
send messages on multiple channels, they are marked as seen
on all those channels, allowing dynamic switching in case
of channel connection failures.
In addition there are two minor improvements to debug
messages.
This is the first mitigation of issue #105 , so it doesnt crash and prints useful log output for users to handle this issue.
Fixing this problem by switching to another message channel is way more complex.
is supposed to trigger a 60 sec timeout. If not all channels are successfully
joined within those 60 seconds, announce on all IRC servers that already
were joined instead.
Uses protocol.ReconnectingClientFactory as superclass,
which uses exponential backoff in retrying.
Also change on_welcome_trigger callback to reset the
status of message channels which have reconnected,
so that they become operable once reconnected.
