Quoting here for visibility since we rolled over to a new page right after posting. This development dispatch covers work completed since the Decred v0.1.1 release from April 25th, 2016. Since then, developers have merged 37 pull requests of code into 7 software repositories. New repositories were created created and populated for a consolidated miner known as gominer as part of RFP-5 and a statistical dashboard known as dcr-netstats as part of RFP-3 (in addition to decred-dashboard that is hosted at https://dcrstats.com). During this period, a total of 19 commits occurred in these repositories and represent modifications to the effect of 3,777 lines of code added to and 920 lines removed from the Decred codebase (dcrd, dcrwallet, dcrprclient, gominer). 25 commits also occurred in other Decred repositories (dcr-netstats, ccminer, cgminer). A series of RFP milestones were achieved and paid for from the development subsidy. Milestones paid for include (See: Status and Expenditures): - RFP-6: Pool has been successfully tested for 1 week on testnet and configuration verified (x2) (1c640e9, ef20c2e)
Binaries: https://github.com/decred/decred-release/releases/tag/v0.1.2dcrd- getstakedifficulty now returns the calculated stake difficulty of the next block. When the next block is a stake difficulty readjustment, users will now see the upcoming stake difficulty (137-8207e4d)
- Improved fee handling (139-c9a0afa)
- Moved non-mempool specific functions to a new file and added more test coverage (140-14c7cc9)
- Fixed an issue with mempool fees where the memory pool would incorrectly eliminate transactions sent over sendrawtransaction that had high fees while also always rejecting high priority transactions (141-4328736)
- Added a new estimatestakediff RPC command to estimate the minimum and maximum next stake difficulty. The caller can also estimate a new difficulty given a passed number of tickets to be mined in the remaining difficulty period (143-7fd213b)
- Added two new RPC commands designed for wallets running stake pools (stakepooluserinfo and addticket) (144-f1796b0, 148-084edf8)
- Added two new RPC commands to calculate the volume weighted average price of tickets (ticketvwap) and to get the transaction fee information for regular transactions in blocks, the mempool, and a height range (txfeeinfo) (145-29f116c)
- Updated documentation (147-5623458) and versioning (150-f93cb9f)
dcrwallet- Added a non-default allowhighfees flag to wallet that enables users to send transactions that are not safety checked for high fees (214-ec2c1c2)
- Fixed an issue that could cause lock-ups in wallet (219-0e7558d)
- Improved error handling (224-d4ea045)
- Updated versioning (225-e545bec)
dcrrpcclient- Added a number of new RPC commands (addticket, estimatestakediff, settxfee, stakepooluserinfo, ticketpoolvalue, ticketfeeinfo, ticketvwap, txfeeinfo) (16-a5a51f5)
gominer- Enabled TLS, improved configuration, added a sample config file, and updated licensing (3-39550c6)
- Updated configuration (1-d43cd3e, 2-43e6a84)
ccminer/cgminerDeveloper NotesAdded stake pool fee functionalityWe have added new config flags for dcrwallet. Let's go over each option to make crystal clear its usage: stakepoolcoldextkeyWhen this option is set it turns on stake pool functionality for wallet. When stake pool is enabled for wallet, there are a series of transaction checks to verify whether this wallet will vote for a ticket that has used this stake pool's address as the ticketaddress. This option requires the extended public key of the stake pool's cold wallet that will receive the pool's fees. So on simnet for instance this option looks like this: --stakepoolcoldextkey=spubVWAdividNTiSM9SdLRA5JX6LYNwt58cd51TFnpnULGQ8oqNMNskfkQwU7rjWMCY7phBguVr4XTmAWyDVRKpo2dFyjFb6QG4ihB8w64UPNuu:1000
The first portion (spub..., or dpub... on mainnet) is the extended public key and the second (1000) is the number of addresses to derive. Every user of the pool gets their own cold fee wallet address derived, so we recommend using at least 1000 in anticipation of the relative number of users in the stake pool. When a vote is created by the stake pool to vote on a ticket that has been given voting rights, it pays the pool fee to the address derived for the cold wallet from this extended public key. pooladdressThis is for use by the stake pool user. It will be an address provided to the user by the stake pool. If set, this address is used during ticket purchase and will commit to a small output in the ticket that gives the stake pool its required fees. ticketaddressSame as the old option. This is the address that the stake pool user is giving the ticket's voting rights to. poolfeesThis is the required ticket fee as requested by the stake pool. The value set by the user needs to be greater than or equal to that of the pool. The fee is a percentage based fee, based on the stake subsidy. Here is a concrete example from simnet: The ticket price of this ticket was 46.0551008, and the ticket relay fees were 0.00000100 per kB. The pool fees were set to 1.00%. The subsidy on simnet at this block height is approximately 29.40888 Coins per vote. This is the ticket as purchased by the user: "vin": [

"vout": [

And here's the vote that the stake pool created for that user's ticket: "vin": [

{

"vout": [
{

"scriptPubKey": {

"addresses": [
"SsYUi5tbXfqHnTPgvHcajNW4yiGeSP6n7Xq"

}
}
]
As you can see '"n": 2,', the third output, is the stake pool fee of 0.2940888. This is 1% of the vote reward at that point (0.2940888/29.40888). The remaining subsidy and the original coins are returned to the take pool user in output '"n": 3,'. For more information about stake fees, please refer to dcrwallet/wallet/txrules/doc.go. |

This development dispatch covers work completed since the Decred v0.1.0 release from April 18th, 2016. Since then, developers have merged 18 pull requests of code into 3 software repositories. During this period, a total of 18 commits occurred in these repositories and represent modifications to the effect of 848 lines of code added to and 275 lines removed from the codebase. A series of RFP milestones were achieved and paid for from the development subsidy. Milestones paid for include (See: Status and Expenditures): - RFP-3: Port has been completed (limited milestones) (6ae7950)
- RFP-6: Pool has been successfully tested for 1 week on testnet and configuration verified (x4) (e5bcf90, f9ea04d, e94c540, fc58177)
Binaries: https://github.com/decred/decred-release/releases/tag/v0.1.1dcrd- Added a check to disallow by default transactions to be broadcast if the fee per kilobyte is 100x above the minimum (0.01 DCR). This check does not affect other incoming transactions to the node, it only checks transactions going out of the node (124-b7e88f4)
- Added a new RPC command called ticketfeeinfo to provide statistical information about ticket fees per kilobyte for the mempool, recent blocks, and recent difficulty windows (132-41abd20)
- Updated fee calculation (125-a5ca12f), error handling (127-82a0e17), documentation (128-fd40243), and versioning (136-4f8ad73)
dcrwallet- Fixed the build when using newer versions of the gRPC packages (189-3f411f0)
- Isolated the address pool to prevent excessive address creation (192-4e689d6)
- Fixed an issue where the purchaseticket RPC command would fail if the ticket address or pool address was undeclared, not allowing the user to set the ticket expiry if either was absent (198-0740964)
- Added ability to change the ticket autopurchase frequency and changed the frequency to a default of 1 (can be changed with the command-line argument --ticketbuyfreq=) (201-823bddb)
- Fixed an issue that prevented Paymetheus from starting properly (203-b28ae9a)
- Updated dust calculation (193-df0af6e), fee calculation (194-5d77ddb), documentation (195-2a1e04c, 208-0bcc487), index scan length (196-38cdae0), user prompts (202-8ed9a8c), and versioning (209-c5e47fb)

This development dispatch covers work completed since the Decred v0.0.10 release from April 7th, 2016. Since then, developers have merged 28 pull requests of code into 4 software repositories. During this period, a total of 28 commits occurred in these repositories and represent modifications to the effect of 1,991 lines of code added to and 602 lines removed from the codebase. A series of RFP milestones were achieved and paid for from the development subsidy. Deliverables from the milestones will begin appearing in the Decred ecosystem in the near future. These include another network overview and indicator dashboard (RFP-3), a new documentation system available for community feedback and contribution (RFP-4), new and updated binary builds for Windows and Linux for cgminer and ccminer (RFP-5), and new independently-operated mainnet stake pools (RFP-6). Milestones paid for include (See: Status and Expenditures): - Final modifications and documentation in RFP-1 (423fd36)
- Generate copy for obtaining Decred funds, using the block explorer, and PoW mining documentation, and review and provide feedback on copy for introduction, wallet setup, stake mining and network parameters documentation in RFP-4 (14e3bb1, 682b50a)
- Pool has been successfully tested for 1 week on testnet and configuration verified in RFP-6 (x2) (d99401c, 74faad5)
Binaries: https://github.com/decred/decred-release/releases/tag/v0.1.0dcrd- Fixed constructors for new RPC account commands (106-0119cd6)
- Added option to change the home directory (109-851569f)
- Fixed fall through on invalid transaction types for getrawmempool (111-2459171)
- Merged policy.go changes from btcd to fix fee calculation issues (112-936b379)
- Fixed an issue with the mining transaction selection algorithm where it failed to sort stake transactions effectively. The codebase now defaults to no priority size spacing in the block, correctly sorts transactions by their stake importance, and then sub-sorts them by fees (113-2ba4225)
- Fixed an issue to ensure proper handling when attempting reorganization to an eligible block (117-b75a280)
- Fixed getrawtransaction verbose output to correctly display ticket commitments (address and amount) (119-678b454)
- Modified the purchaseticket RPC command to add new fields now used by wallet (121-ca8935f)
- Improved error handling for transactions (122-9559b0a)
- Updated configuration (107-073d412), documentation (118-5c79172), and versioning (123-a339852)
dcrwallet- Fixed an issue that could cause an unusual locking up of the wallet when requesting a transaction, such as through sendtoaddress. The address is pulled before the database transaction is opened and then committed to later if the transaction succeeds and includes the change address (167-eb9d082)
- Fixed attempted syncing when connected to an empty chain so cold wallets connect properly (169-d519d55)
- Fixed an issue with getwalletfee consistency (172-bce92a7)
- Added a sweepaccount tool that creates on-chain transactions, one per used address in a source account, to sweep all output value to new addresses in a different destination account (173-a4b8c49)
- Fixed an issue in address manager sync error handling (176-5166dcc)
- Fixed an issue in wallet auto-syncing for wallets synced from seed (177-6be3794)
- Changed default relay fees from 0.05 to 0.01 DCR per KB (182-adc0d74)
- Replaced ticket purchase code with new and more robust code. Chains of tickets can now be purchased with ease because outputs to be consumed by tickets are now pregenerated in split transactions. Ticket expiry can now be added to ensure that the tickets will expire in a short time frame, so that the end user can update the ticket fees if their tickets fail to be added to a block. Tickets can now pay a fee to a pool that is set by the user. The fee determines the amount that the user will contribute to the pool. The pool then receives this amount plus subsidy (183-780c3ce)
- Refactored address index syncing code to enhance the synchronization speed of wallet on restore from seed and start up. A new flag has been added to allow users to optionally set their final address index scan lengths (184-286287f)
- Updated configuration (168-d45ff26), user prompts (180-2e788aa), and versioning (185-b192834)
dcrrpcclient- Added RPC client handling for the new RPC commands in dcrd (existsaddresses, livetickets) and dcrwallet (accountaddressindex, accountfetchaddresses, accountsyncaddressindex, walletinfo) (12-e297cfc)
- Fixed purchaseticket caller (14-f005c4a)
- Updated configuration (13-3a9c419)

This development dispatch covers work completed since the Decred v0.0.8 release from March 18th, 2016. Since then, developers have merged 21 pull requests of code into 3 software repositories. During this period, a total of 25 commits occurred in these repositories and represent modifications to the effect of 8,622 lines of code added to and 13,221 lines removed from the codebase. A new request for proposal (RFP) has been opened to establish and operate additional stake pools in a number of geolocations. Several parties have stepped forward, and the project is working with them to set up the new infrastructure. Design deliverables for RFP-1 are nearing completion, the first component of RFP-4 is complete and will be integrated into a documentation system in the future, and a number of milestones are being completed and put into Decred repositories for RFP-5. Work continues on RFP-1 through 6. Finally, Paymetheus, the Windows wallet GUI for Decred has been made available as a testnet pre-release prior to the completion of RFP-1's improvements. Binaries: https://github.com/decred/decred-release/releases/tag/v0.0.9dcrd- Added new IsUnspendable function required for the latest dcrwallet sync that takes a public key script and returns whether it is spendable (96-5fcef8a)

Fee estimation constants and test vectors have also been updated for Decred's transaction sizes (127-2133b7b)
- Added a new wtxmgr API for resumable, incremental input selection that is performed under a single database transaction, and hooks up the API for transaction creation in the wallet package (130-b0aff95)
- Fixed updating the UTXO set for imported addresses to always update spending data even if the transaction already exists (133-a488b38)
- Refactored address pool code to scale to more accounts than the default account, updated address pools to be generalized so that in the future they can be multi-account, and greatly simplified logic for the address pool. Accounts are automatically resynced when the wallet is restored from seed (134-4b64adf)
- Removed voting pool package as it is currently unused in Decred (135-d98dc43)
- Ensured resync has been completed before launching notification handling so that wallet would not drop or mishandle notifications that came in synchronously when wallet resynced (136-6bf720c)

The Decred Windows wallet GUI has been released as a testnet pre-release. It is native to Windows, early access with caveats, and without any bells and whistles (from RFP-1). But this is the foundation. Later on, native GUIs will exist for Mac OS X and Linux as well. Please read the announcement here if you are interested in helping the project test it. |

|
|
In case you do not know, a new RFP has been posted to host and maintain new stake pools in diverse geolocations. If you are interested, see if you can apply as a group or a pair. Several experienced and talented groups have already stepped forward and will launch and maintain new stake pools for users. Have a look here if this interests you. |

Quick update to let everyone know to upgrade to v0.0.7. The current mempool is rejecting stake pool votes, so if you want more mining subsidy, you should upgrade. It is a priority release that fixes an issue in IsStandard transaction checks where daemons were failing to relay pool-produced votes. The binaries are available here: https://github.com/decred/decred-release/releases/tag/v0.0.7 |
