bitcoinj now uses ElectrumX as an UTXO provider in order to keep track
of coins in BIP32 deterministic wallet.
Trade responder (Alice) needs to pass a BIP32 extended private key to API
so trade-bot can create unattended spends.
Both Alice and Bob can find their final funds in accounts using the
ephemeral 'tradePrivateKey' from trade-bot state data.
Most cross-chain API calls are now only allowed from localhost.
Most Bitcoin fees pegged at 0.00001000 BTC.
More work needed to handle refunds in case of trade failures.
(See XXX comment tags in TradeBot.java)
Qortal AT now includes suggested tradeTimeout again as a constant so trade partner/recipient can use that to calculate a suitable lockTimeA. CODE_HASH changed!
Renamed some secret_hash to hash_of_secret.
Changed TradeBotStates.trade_state back to TINYINT and adjusted values in TradeBotData.State enum to suit.
Added lockTimeA to TradeBotData & repository.
Added JAXB-only extra representations of Bitcoin PKHs as addresses.
Fixed incorrect expected length in BTCACCT.extractOfferMessageData().
CrossChainTradeData.refundTimeout now only present in TRADE mode.
Added BTC.pkhToAddress().
Added initial TradeBot.handleAliceWaitingForP2shA().
Enforce only one TradeBot thread running using 'activeFlag' atomic boolean.
Replace incorrect SHA256 with HASH160 for hashOfSecretA in TradeBot.startResponse().
BTC.getBalance() now returns Long instead of Coin.
BTC.FORMAT.format(Coin) changed to BTC.format(Coin or long).
Added BTC.deriveP2shAddress(byte[] redeemScriptBytes).
Added GET_MESSAGE_LENGTH_FROM_TX_IN_A
and PUT_PARTIAL_MESSAGE_FROM_TX_IN_A_INTO_B.
Replaced AT-1.3.4 with version including bug-fix for off-by-one
data address bounds checking.
Moved long-from-bytes method to BitTwiddling class.
Renamed some methods to make it more obvious they work with
little/big endian data.
Incorrect column names when saving a group ban.
Missing column in LeaveGroupTransactions.
More stringent validity checks in group-kick, group-ban and remove-group-admin.
Added loads more tests to cover group actions.
Renamed GET /blocks/minters to /blocks/signers
Renamed GET /blocks/minter/{address} to /blocks/signer/{address}
Changed corresponding repository methods and data classes.
Any reward leftover from ditributing to legacy QORA holders is reallocated to either:
founders if any online
or
account-level-based reward candidates, if no founders online
We should get pretty close to 100% block reward distribution, barring rounding artifacts.
More documentation and tests.
Removed BlockChain's founderShare as it is calculated in Block on a per-block basis instead.
Now we sum generic block reward + transaction fees before performing
distribution only once.
Added Map to collate account-balance changes during block reward
distribution so the final changes can be applied in one batch,
reducing DB load.
Some other optimizations like a faster ExpandedAccount.getShareBin().
Passes test EXCEPT RewardTests.testLegacyQoraReward(), pending decision
on how to reallocate 'unspent' block reward.
No more bitcoinj peer-group stalls, or slow startups,
or downloading tons of block headers, or checkpoint files.
Now we use ElectrumX protocol to query info from random servers.
Also:
BTC.hash160 callers now use Crypto.hash160 instead.
Added BitTwiddling.fromLEBytes() returns int.
Unit tests seem OK, but needs complete testnet ACCT walkthrough.
Group owner now derived from CREATE_GROUP transaction creator's public key.
Added 'reduced' group name to GroupData, with corresponding change to DB.
Renamed GroupData.getIsOpen() to simply isOpen().
Tidied up CreateGroupTransactionData, adding 'reduced' group name.
Renamed getIsOpen() to simply isOpen().
Added code to generated reduced group name when building genesis block.
Added Group.MIN_NAME_SIZE of 3.
DB tables changed to add reduced_group_name where appropriate,
removing owner where necessary.
Added GroupRepository.reducedGroupNameExists(String).
Fixed up test blockchain configs in src/test/resources/test-chain-v2*.json.
This allows on-chain messages to a group, including NO_GROUP / groupID zero.
No-recipient messages cannot have an amount - where would it go?
Changed MESSAGE serialization layout to add boolean indicating
whether recipient is present.
Changed MESSAGE serialization layout so assetID is after amount,
and only present if amount is non-zero.
Changed DB table structures to cover above.
Added unit tests to cover above.
Owner now derived from issuer's public key.
Maximum asset name length reduced to 40 characters.
Repository table changes.
"owner" removed from test blockchain configs and "issuerPublicKey" used instead
where applicable.
Some getters in the form of "getIs___()" renamed to simply "is____()".
Changes include:
* Allowing renaming
* Tracking last-updated timestamps
* More stringent Unicode processing
* Way more unit tests
* Max name length reduction to 40 chars
Note: HSQLDB repository table changes
Controller no longer starts up BTC support during main startup.
This does mean that BTC startup is deferred until first BTC-related
action, and that the first BTC-related action will take much longer
to complete.
Added tests to cover startup/shutdown.
This also fixes splash logo stuck on-screen and broken Controller
shutdown when using REGTEST bitcoin network AND there is no
local regtest bitcoin server running.
REGISTER_NAME has an "owner" field which can be different from the actual
registrant (transaction creator's public key, used for signing transaction).
This allowed people to register names to be owned by someone else, thus breaking
the whole "one name per account" aspect.
So now "owner" is removed from REGISTER_NAME, and the actual owner address is
derived from transaction creator's public key, as you would expect.
Similarly, UPDATE_NAME has a corresponding "newOwner" field which has been removed.
In addition, UPDATE_NAME now allows users to change their registered name using a new
"newName" field.
Various changes made to DB, Name class, etc. to accomodate above, along with some minor
bug-fixes and comment improvements/corrections.
Needs new unit tests to cover both new functionality and old!
Collated all development changes to DB so now we build
initial DB structure directly with final layout.
i.e. no ALTER TABLE, etc.
Reordered HSQLDB 'CREATE TYPE' statements into alphabetical order
for easier maintainability.
Replaced TIMESTAMP WITH TIME ZONE with simple BIGINT ("EpochMillis").
Timezone conversion is now a presentation task, rather than having
pretty values in database.
Removed associated conversion methods, like toOffsetDateTime(),
fromOffsetDateTime() and getZonedTimestampMilli().
Renamed some DB columns to make them more obviously timestamps, like:
Names.registered is now Names.registered_when.
Removed IFNULL(balance, 0) from HSQLDBAccountRepository as balances
are never null, or actually never 0 either.
Added more tests to increase API call, and hence repository, coverage.
Removed unused "milestone block" from Transactions.
In some cases, a freshly cancelled reward-share could still have
an associated signed timestamp. Block.mint() failed to spot this
and used an incorrect "online account" index when building the
to-be-minted block.
Block.mint() now checks that AccountRepository.getRewardShareIndex()
doesn't return null, i.e. indicating that the associated reward-share
for that "online account" no longer exists.
In turn, AccountRepository.getRewardShareIndex() didn't fulfill its
contract of returning null when the passed public key wasn't present
in the repository. So this method has been corrected also.
AccountRepository.rewardShareExists(byte[] publicKey) : boolean added.
BlockMinter had another bug where it didn't check the return from
Block.remint() for null properly. This has been fixed.
BlockMinter now has additional logging, with cool-off to prevent log
spam, for situations where minting could not happen.
Unit test (DisagreementTests) added to cover cancelled reward-share
case above. BlockMinter testing support slightly modified to help.
Moved Asset.MULTIPLIER, etc. to Amounts class.
Had to reintroduce BigInteger for asset trading code.
Various helper methods added to Amounts class.
Payment.process/orphan no longer needs unused transaction
signature or reference.
Added post block process/orphan tidying, which currently deletes zero account balances to satisfy post-orphan checks in unit tests.
Fix for possible bug when orphaning TRANSFER_PRIVS.
Added RewardSharePercentTypeAdapter like AmountTypeAdapter.
Replaced a whole load of JAXB-special getters with type-adapters.
Tests looking good!
Now possible thanks to removing Qora v1 support.
Maximum asset quantities now unified to 10_000_000_000,
to 8 decimal places, removing prior 10 billion billion
indivisible maximum.
All values can now fit into a 64bit long.
(Except maybe when processing asset trades).
Added a general-use JAXB AmountTypeAdapter for converting
amounts to/from String/long.
Asset trading engine split into more methods for easier
readability.
Switched to using FIXED founder block reward distribution code,
ready for launch.
In HSQLDBDatabaseUpdates,
QortalAmount changed from DECIMAL(27, 0) to BIGINT
RewardSharePercent added to replace DECIMAL(5,2) with INT
Ripped out unused Transaction.isInvolved and Transaction.getAmount
in all subclasses.
Changed
Transaction.getRecipientAccounts() : List<Account>
to
Transaction.getRecipientAddresses() : List<String>
as only addresses are ever used.
Corrected returned values for above getRecipientAddresses() for
some transaction subclasses.
Added some account caching to some transactions to reduce repeated
loads during validation and then processing.
Transaction transformers:
Changed serialization of asset amounts from using 12 bytes to
now standard 8 byte long.
Updated transaction 'layouts' to reflect new sizes.
RewardShareTransactionTransformer still uses 8byte long to represent
reward share percent.
Updated some unit tests - more work needed!
CHAT transactions don't ever get included into a block.
They use a memory-intensive proof-of-work instead of a fee.
Reference field isn't checked but must be present.
Recipient is optional.
isText/isEncrypted as per MESSAGE, basically indicative flags only.
Some API support.
Memory PoW takes roughly 800ms on Ryzen 3600, maybe 2400ms on QORTector?
As this changes how lastReferences are checked and updated,
this is not suitable for rolling into current chain without a
"feature trigger", or chain restart!
Added unit tests.
Qortal is never going to continue off the old Qora blockchain,
so removed all code regarding compatibility.
Removals include:
* various blockchain "feature triggers"
* special Qora-only broken code for various transaction signatures
* "old" asset pricing / trading
* pre-group txGroupId field in transactions
* compatibility unit tests
Possibly safe for roll-out on pre-genesis blockchain?
Tidied up duplicated cross-chain API code that
fetched Qortal AT info.
Added Bitcoin-related cross-chain API calls
for building, checking, refunding and redeeming
P2SH.
Added new Bitcoin-related API error codes.
Controller now starts up, and shuts down, bitcoinj.
Speed-up in BTC class so bitcoinj doesn't have
to throw away all peers and rediscover & reconnect
to them with every chain-related call.
Added API calls to aid Qortal-side of cross-chain trading.
POST /crosschain/build - for building Qortal AT
POST /crosschain/tradeoffer/recipient - for sending trade partner/recipient to AT
POST /crosschain/tradeoffer/secret - for sending secret to AT
DELETE /crosschain/tradeoffer - for cancelling AT
More fixes regarding Blocks processing/orphaning ATs.
More fixes regarding sending/receiving blocks containing AT data.
AT-related fix to genesis block.
Improved cross-chain trading AT code, removing offer-mode timeout
and replacing that with allowing AT creator to cancel offer/end AT
by sending AT the creator's own address as trade partner/recipient.
After all, they're not going to trade with themselves.
Added assertion to check BTCACCT.CODE_BYTES_HASH matches compiled code hash.
Added cross-chain AT's 'mode' for easier diagnosis, either OFFER or TRADE.
We can't use AT's signature to generate AT address because address is needed
before DEPLOY_AT transaction is signed. So we use a hash of signature-less
transaction bytes.
Corresponding changes to tests.
Reworked the cross-chain trading AT so it is now 2-stage:
stage 1: 'offer' mode
waiting for message from creator containing trade partner's address
stage 2: 'trade' mode
waiting for message from trade partner containing secret
Adjusted unit tests to cover above.
Changed QortalATAPI.putCreatorAddressIntoB from storing
creator's public key to actually storing creator's address.
Refactored BTCACCT.AtConstants to CrossChainTradeData.
Now we also store hash of AT's code bytes in DB so we can look up
ATs by what they do. Affects ATData class, ATRepository, etc.
Added "Automated Transactions" and "Cross-Chain" API sections.
New API call GET /at/byfunction/{codehash} for looking up ATs
by what they do, based on hash of their code bytes.
New API call GET /at/{ataddress} for fetching info for specific AT.
New API call GET /at/{ataddress}/data for fetch an AT's data segment.
Mostly for diagnosis of AT's current state.
New API call POST /at for building a raw, unsigned DEPLOY_AT transaction.
New API call GET /crosschain/tradeoffers for finding open BTC-QORT trading ATs.
We require AT v1.3.4 now!
Updated AT-related logging.
Added "isInitial" flag to AT state data so that state data created at
deployment is not added to serialized block data.
Updated BTC-QORT AT code and tests to cover various scenarios.
Added missing 'testNtpOffset' to various test versions of 'settings.json'.
Added missing 'ciyamAtSettings' to various test blockchain configs.
Loads of AT-related additions/fixes/etc. to core code, e.g Block
Requires fix in CIYAM AT v1.3.2
New version of Qortal cross-trade AT code.
Change how Qortal addresses are managed in QortalATAPI from using
base58 strings (that are too long) to using hex form (25 bytes)
as they need to fix into 32 byte A/B register.
Generate AT addresses using DeployAtTransaction's signature instead
of convoluted hash of AT data like name, description, etc.
Add startTime as arg to GetTransaction test app.
Add missing fields (name, description, ATType, tags) to DeployAT test app.
Bump CIYAM AT requirement to v1.3
Remove multi-blockchain AT aspect for now (BlockchainAPI).
For PUT_PREVIOUS_BLOCK_HASH_INTO_A we no longer use SHA256 to condense 64-byte block signature into 32 bytes.
Now we put block height into A1 and SHA192 of signature into A2 through A4.
This allows possible future lookup of block data using "block hash", with verification that it is the same block.
Some AT functions use "address in B" but sometimes we populate B with account's public key instead.
So the method "getAccountFromB" is smart and checks for an actual, textual address in B starting with 'Q', otherwise assumes B contains public key.
The Settings field "useBitcoinTestNet" (boolean) now replaced with "bitcoinNet" (String) with possible values MAIN (default), TEST3, REGTEST.
This allows for more varied development/testing scenarios.
Use correct Bitcoin nSequence value 0xFFFFFFFE for P2SH, i.e. enable locktime, disable RBF.
Roll REGTEST checkpoints file generator into main BTC class.
Yet another rewrite of Bitcoin P2SH scripts for BTC-QORT cross-chain trading.
Added associated test classes BuildP2SH, CheckP2SH, DeployAT (unfinished).
Streamlined BTC class and switched to memory block store.
Split BTCACCTTests into BTCACCT utility class and (so far)
three stand-alone apps: Initiate1, Refund2 and Respond2
Moved some Qortal-specific CIYAM AT constants into blockchain config.
Removed redundant BTCTests
Bump bitcoinj to 0.15.5 for fixes.
lockTime is int (seconds since epoch), not long (ms since epoch).
Improve output of Initiate1.
Added (most of) Respond2.
Added a setting "showBackupNotification", which is false by default,
that shows a tray notification when a repository backup occurs.
Above notification, and the auto-update notification, now refer to
the SysTray i18n translation lookup resources.
Added Ed25519 private key to public key function accessible from SQL.
Added Ed25519 public key to Qortal address function accessible from SQL.
Used above functions to store minting account public key in SQL to
reduce the number of unnecessarily repeated Ed25519 conversions.
Used above functions to store reward-share minting's accounts address
to reduce the number of unneccessarily repeated PK-to-address conversions.
Reduced the usage of PublicKeyAccount to simply Account where possible,
to reduce the number of Ed25519 conversions.
Account.canMint(), Account.canRewardShare() and Account.getEffectiveMintingLevel()
now only perform 1 repository fetch instead of potentially 2 or more.
Cleaned up NTP main thread to reduce CPU load.
A fixed offset can be applied to NTP.getTime() responses, for both
scenarios when NTP is running or not. Useful for testing or simulating
distant remote peers.
Controller.onNetworkMessage() and Network.onMessage() have both had their
complexity simplified by extracting per-case code to separate methods.
Network's EPC engine's thread pool size no longer hard-coded, but comes
from Settings.maxNetworkThreadPoolSize, which is still 10 by default,
but can be increased for high-availability nodes.
Network's EPC task-producing code streamlined to reduce CPU load.
Generally reduced calls to System.currentTimeMillis(), especially
where the value would only be used in verbose logging situations,
and especially in high-call-volume methods, like within repository.
Keep track of when EPC engine can't spawn a new thread as this
might indicate thread-pool exhaustion and cause some network
messages to be lost.
If logging level is NOT 'trace' (or 'all') then don't call
System.currentTimeMillis() as we'll never use the value.
Similarly, don't set thread names if not logging at 'trace' either.
Update EPC tests, particularly unified per-second/end-of-test stats
reporting.
Added API call GET /peers/enginestats to allow external monitoring.
Extract all engine stats in one synchronized block, instead of
separate calls, for better consistency.
No more "node UI". UI provided by 3rd party.
"Open UI" tray icon menu item now attempts to open UI at various
local servers (see Settings.uilocalServers) or some random
remote server (Settings.uiRemoteServers).
Default UI port now 12388 (Settings.uiPort).
Translator class no longer logs warnings for every failed translation.
Commented out unused ApiError enum entries.
Renamed some ApiError names like "_NO_EXISTS" to "_UNKNOWN".
Removed old src/main/resources/globalization/* files.
Added CheckTranslations test app.
Fixed some extraneous/missing ApiError aspects in some API-related classes.
e.g. added NAME_UNKNOWN to GET /names/{name}
We've never needed this before but now it's fixed.
Added corresponding +ve & -ve tests just to make sure.
Only actual use-case that comes to mind is cancelling reward-share.
Before:
0-fee self-share REWARD_SHARE when there is an existing self-share would result in
INSUFFICIENT_FEE from isFeeValid()
After:
isFeeValid() returns OK for above, but isValid() returns SELF_SHARE_EXISTS.
In addition, a transaction that tries to modify existing self-share, even with fee,
also returns SELF_SHARE_EXISTS.
Improved tests to double check.
NOTE: first startup after this commit can take a while due to building index!
SQL statement "DELETE FROM HistoricAccountBalances WHERE height >= ?" required
a full table scan and so was very slow on VMs/routers. This statement used by
HSQLDBAccountRepository.deleteBalancesFromHeight(), itself called during
Block.orphan().
Symptoms particularly evident during shutdown where above statement could take
upwards of 15 minutes on single-CPU, small-memory VMs!
Statement wasn't noticed before as slow-query checking wasn't involved.
Slow-query checking now applies to HSQLDBRepository.delete() and
HSQLDBRepository.exists() calls.
Added test for correct HSQLDB interrupt handling.
Fixed some typos.
Blockchain configs will need "v2Timestamp" feature trigger renaming to "qortalTimestamp"!
Due to Controller.VERSION_PREFIX changing, peer-to-peer protocol version detection has
been changed. Was previous a substring match, now we test peers's buildTimestamp is at
least Peer.V2_PROTOCOL_TIMESTAMP_THRESHOLD. Changes in Peer.java.
Also added comment and throw() to QortalATAPI.getNextTransactionTimestamp()
as this needs given the change to Qortal's block timestamps from legacy Qora.
Changes to HSQLDB data types, e.g. QoraAddress to QortalAddress, means existing
database will need to be thrown away after this commit!
Converted AccountData's initialLevel to blocksMintedAdjustment.
Corresponding changes to AccountLevelTransaction so that level
set in genesis block is converted to blocksMintedAdjustment,
via cumulativeBlocksByLevel.
Ditto changes to HSQLDBAccountRepository, HSQLDBDatabaseUpdates,
[HSQLDB]TransactionRepository, etc.
Changes to API call POST /admin/mintingaccounts to check passed
reward-share private key maps to a reward-share with minting
account that still has privilege to mint. It's possible for
a TRANSFER_PRIVS transaction to transfer away minting privileges
from a minting account referenced by in a reward-share.
Change to RewardShareTransaction to allow users to cancel a
reward-share even if minting-account component no longer has
minting privs. This should allow users to clean up more after
a privs transfer.
Re-order processing/orphaning in Block.process()/Block.orphan()
to be more consistent and also to take in account changes that
might have been caused by TRANSFER_PRIVS transactions which affect
who might actually receive block rewards/tx fees.
Founders now gain blocksMinted & levels as part of minting blocks.
(Needed to make TRANSFER_PRIVS from a founder account to work).
BlockMinter now has added checks to make sure that the reward-shares
it might use to mint blocks still have valid minting-accounts.
i.e. that the minting-account component of reward-share hasn't had
minting privs transferred away by TRANSFER_PRIVS tx.
Controller now rejects online-accounts from peers that no longer
have minting privs (e.g. transferred away by TRANSFER_PRIVS)
Corresponding, Controller no longer SENDS online-accounts that no
longer have minting privs to other peers.
Added some tests - more tests needed, e.g. for multiple transfers
into the same account, or a test for minting post transfer for both
sender & recipient.
Now reward-shares with zero percent are valid, to allow the 'recipient' party to gain
"number of minted blocks" but no actual block reward.
Correspondly, the special zero share used to cancel reward-shares has been changed to
be any negative value.
Block rewards, founder 'leftovers': if founder is minter account in any online
reward shares, then the per-founder-share is spread across their online reward-shares,
otherwise it's simply/wholy given to that founder.
Created a new DB table to hold "next block height", updated via triggers on Blocks.
This is so various sub-queries can simply read the next-block-height value instead
of complex IFNULL(MAX(height),0)+1 or SELECT height FROM Blocks ORDER BY height DESC.
Prior code was also broken in edge cases, e.g. no genesis block, or ran slow.
Added tests to cover above.
Deleted BTC tests as they're obsolete.
Added/improved other tests.
*** WARNING ***
Possible block reward bug in this commit. Further investigation needed.
Reverted AccountBalances back to height-less form.
Added HistoricAccountBalances table that is populated via trigger on AccountBalances.
This saves work when performing common requests for latest/confirmed balances,
shunting the extra work to when requesting height-related account balances.
Unified API call GET /addresses/balance/{address} by having address/assetId/height as
query params.
Simpler call for fetching legacy QORA holders during block rewarding.
Improved SQL for fetching asset balances, in all conditions,
e.g. with/without filtering addresses, with/without filtering assetIds,
etc.
Unit test for above to make sure query execution is fast enough.
(At one point, some SQL query was taking 6 seconds!)
Added optional 'height' Integer to AccountBalanceData, but this
is not populated/used very often.
HSQLDBAccountRepository.save(AccountBalanceData) now checks zero balance saves
to see if the row can be deleted instead. This fixes a lot of unhappy tests
that complain that there are residual account balance rows left after
post-test orphaning back to genesis block.
Yet more tests.
Removed very old 'TransactionTests' which are mostly covered in more specific tests elsewhere.
Added cancel-sell-name test from above.
Fixed AssetsApiTests to check for QORT not QORA!
Changed hard-coded assetIDs in test.common.AssetUtils in light of new LEGACY_QORA & QORT_FROM_QORA genesis assets.
Some test blockchain config changes.
Also:
RewardShareKeys app now supports only one arg (minter private key)
in self-reward-share mode, where recipient public key is derived
from minter private key.
Added methods to Account for returning 'effective' minting level
where minting level for founders is read from blockchain config.
(Or returns zero if unable to mint).
Changed two Block constructors into static methods that return
a new Block as there was way too much work being done to really
be called a constructor, especially with all the opportunities
to throw an exception too.
Main blockchain config updated to reflect near-launch version.
Added/changed blockchain weight tests to check block winning
based on higher account levels.
Added Transaction.isFeeValid() to allow transaction subclasses to override and allow zero fees, etc.
Added tests to cover self-reward-shares, including zero fee scenario.
Set 'dilbert' test account to level 8 in test genesis block.
Removed leftover mention of "previous_level" from HSQLDBAccountLevelTransactions,
and AccountLevelTransactionData. (Previous level makes no sense as ACCOUNT_LEVEL
transactions are genesis-block only).
Fixed some incorrect uses of PrivateKeyAccount.getSharedSecret() to
PrivateKeyAccount.getRewardSharePrivateKey() in tests.
Unified terminology from block "generator", "forger", etc. to "minter"
Unified terminology "proxy forger" to "reward share" as it was
incorrect, or at least highly ambiguous, which account had which role.
AccountRepository.findRewardShares() has different arg order!
Account.canMint() now returns true if account has 'founder' flag set.
Added Account.canRewardShare() which returns whether acocunt can create
a reward-share (e.g. level 5+ or founder).
Fixed HSQLDBAssetRepository.getAllAssets() which had incorrect
resultSet column indexes.
Removed old traces of EnableForging transaction.
ACCOUNT_LEVEL and ACCOUNT_FLAGS (genesis-block-only transaction types)
now set target account's last-reference. This is allow later REWARD_SHARE
transactions in genesis block and post-genesis transactions by that account.
REWARD_SHARE transactions are now FREE, but only if minter is also recipient.
If a self-reward-share already exists, then unless share-percent is zero (to
terminate reward-share), any subsequent self-reward-share is invalid.
Updated SysTray i18n properties file.
BlockChain config file requires 'minAccountLevelToRewardShare' and optional
'minAccountLevelToMint'.
Added potential, but currently unused, memory-hard PoW algorithm.
Fixed/removed/disabled some unit tests.
BlockMinter.generateTestingBlock asks Controller to pretend mintingAccount is 'online'.
More testing needed!
