- With nodes coming and going on the network, the network could come to different opinions about who should get paid next in line due to some nodes being flagged as failing a PoSe check. This will have to be fixed by introducing a blockchain based PoSe system, but that's out of the scope of this release. To fix the issues in the interrim, I'm removing PoSe checks for the time being.
- Masternode nLastPaid is removed and a new caching system that keeps the last 30 days of coinbase payees replaces it
- To deal with some significant attack vectors, the masternode donation feature was removed. The donation feature was added to support developement anyway, so this will be replaced by the budgeting code.
- This code should allow the network to come to consensus about who should be paid pretty effectively
- implement find_value() function for UniValue
- replace all Array/Value/Object types with UniValues, remove JSON Spirit to UniValue wrapper
- remove JSON Spirit sources

This class groups transactions that have been confirmed in blocks into buckets, based on either their fee or their priority. Then for each bucket, the class calculates what percentage of the transactions were confirmed within various numbers of blocks. It does this by keeping an exponentially decaying moving history for each bucket and confirm block count of the percentage of transactions in that bucket that were confirmed within that number of blocks.
-Eliminate txs which didn't have all inputs available at entry from fee/pri calcs
-Add dynamic breakpoints and tracking of confirmation delays in mempool transactions
-Remove old CMinerPolicyEstimator and CBlockAverage code
-New smartfees.py
-Pass a flag to the estimation code, using IsInitialBlockDownload as a proxy for when we are still catching up and we shouldn't be counting how many blocks it takes for transactions to be included.
-Add a policyestimator unit test
- Removed of reference node and replaced with decentralized quorums that pick the masternodes who get paid each block.
- Made a budgeting system, where masternodes can vote on individual budgets and the data is stored perminently on each clients computer
- Ensures ports remain open and client are responsive to IX requests.
- Completely 100% decentralized. This farms out the work of checking the masternode network to the masternode network. 1% of the network is determistically selected to check another 1% of the network each block. It takes six separate checks to deactivate a node, thus making it tamper proof.
- Nodes are kept in the masternode list if they fail enough PoSe checks to deactivate. They will continue to be checked until the operator fixes them. However they will not be paid while they're failing checks.
- Detect endian instead of stopping configure on big-endian
- Add `byteswap.h` and `endian.h` header for compatibility with
Windows and other operating systems that don't come with them
- Update `crypto/common.h` functions to use compat
endian header
This was added a while ago for testing purposes, but was never intended to be
used. Remove it until upstream libsecp256k1 decides that verification is
stable/ready.
Backwards-compatibility for libstdc++ is not limited to straightforward abi
changes. Symbol visibility also needs to be taken into consideration, and
that really can't be addressed simply.
Instead, just static-link libstdc++ for backwards-compat.
This makes it easier for us to replace it if desired, since it's now only in
one spot. Also, it avoids the openssl include from allocators.h, which
essentially forced openssl to be included from every compilation unit.

More info regarding KeePass: http://keepass.info/
KeePass integration will use KeePassHttp (https://github.com/pfn/keepasshttp/) to facilitate communications between the client and KeePass. KeePassHttp is a plugin for KeePass 2.x and provides a secure means of exposing KeePass entries via HTTP for clients to consume.
The implementation is dependent on the following:
- crypter.h for AES encryption helper functions.
- rpcprotocol.h for handling RPC communications. Could only be used partially however due some static values in the code.
- OpenSSL for base64 encoding. regular util.h libraries were not used for base64 encoding/decoding since they do not use secure allocation.
- JSON Spirit for reading / writing RPC communications
The following changes were made:
- Added CLI options in help
- Added RPC commands: keepass <genkey|init|setpassphrase>
- Added keepass.h and keepass.cpp which hold the integration routines
- Modified rpcwallet.cpp to support RPC commands
The following new options are available for darkcoind and darkcoin-qt:
-keepass Use KeePass 2 integration using KeePassHttp plugin (default: 0)
-keepassport=<port> Connect to KeePassHttp on port <port> (default: 19455)
-keepasskey=<key> KeePassHttp key for AES encrypted communication with KeePass
-keepassid=<name> KeePassHttp id for the established association
-keepassname=<name> Name to construct url for KeePass entry that stores the wallet passphrase
The following rpc commands are available:
- keepass genkey: generates a base64 encoded 256 bit AES key that can be used for the communication with KeePassHttp. Only necessary for manual configuration. Use init for automatic configuration.
- keepass init: sets up the association between darkcoind and keepass by generating an AES key and sending an association message to KeePassHttp. This will trigger KeePass to ask for an Id for the association. Returns the association and the base64 encoded string for the AES key.
- keepass setpassphrase <passphrase>: updates the passphrase in KeePassHttp to a new value. This should match the passphrase you intend to use for the wallet. Please note that the standard RPC commands walletpassphrasechange and the wallet encrption from the QT GUI already send the updates to KeePassHttp, so this is only necessary for manual manipulation of the password.
Sample initialization flow from darkcoin-qt console (this needs to be done only once to set up the association):
- Have KeePass running with an open database
- Start darkcoin-qt
- Open console
- type: "keepass init" in darkcoin-qt console
- (keepass pops up and asks for an association id, fill that in). Example: mydrkwallet
- response: Association successful. Id: mydrkwalletdarkcoin - Key: AgQkcs6cI7v9tlSYKjG/+s8wJrGALHl3jLosJpPLzUE=
- Edit darkcoin.conf and fill in these values
keepass=1
keepasskey=AgQkcs6cI7v9tlSYKjG/+s8wJrGALHl3jLosJpPLzUE=
keepassid=mydrkwallet
keepassname=testwallet
- Restart darkcoin-qt
At this point, the association is made. The next action depends on your particular situation:
- current wallet is not yet encrypted. Encrypting the wallet will trigger the integration and stores the password in KeePass (Under the 'KeePassHttp Passwords' group, named after keepassname.
- current wallet is already encrypted: use "keepass setpassphrase <passphrase>" to store the passphrase in KeePass.
At this point, the passphrase is stored in KeePassHttp. When Unlocking the wallet, one can use keepass as the passphrase to trigger retrieval of the password. This works from the RPC commands as well as the GUI.
Attempt to codify the possible error statuses associated with script
validation. script/types.h has been created with the expectation that it will
be part of the public lib interface. The other flag enums will be moved here in
a future commit.
Logging has also been removed in order to drop the dependency on core.h. It can
be re-added to bitcoind as-needed. This makes script verification finally free
of application state and boost!
99f41b9 MOVEONLY: core.o -> core/block.o (jtimon)
561e9e9 MOVEONLY: Move script/compressor out of script and put CTxOutCompressor (from core) with it (jtimon)

50f71cd boost: code movement only: split CECKey into separate files (Cory Fields)
bdaec6a boost: remove CPubKey dependency from CECKey. Follow-up of e405aa48 (Cory Fields)
Similar to the INCLUDES changes in 6b099402b4, split out LIBS into individual
entries for more fine-grained control.
Also add MINIUPNPC_LIBS which was missing before, and hook it up to
executables.
