Chia-blockchain

Added

- Node peers are now gossiped between nodes with logic to keep connected nodes on disparate internet networks to partially protect from eclipse attacks. This is the second to last step to remove our temporary introducer and migrate to DNS introducers with peer gossip modeled directly off of Bitcoin. This adds a new database of valid peer nodes that will persist across node restarts. This also makes changes to config.yaml's contents.
- For 'git clone' installs there is now a separate install-gui.sh which speeds up running install.sh for those who wish to run headless and makes docker and other automation simpler.
- The rate limited wallet library now supports coin aggregation for adding additional funds after the time of creation.
- Fees are now used in all applicable rate limited wallet calls
- New parameters for plotting: -r (number of threads) -s (stripe size) -u (number of buckets) in cli and GUI
- chiavdf now has full IFMA optimizations for processors that support it.

Changed

- Multithreading support in chiapos, as well as a new algorithm which is faster and does 70% less IO. This is a significant improvement in speed, much lower total writing, and configurability for different hardware environments.
- Default -b changed to 3072 to improve performance
- The correct amount of memory is used for plotting
- `sh install.sh` was upgraded so that on Ubuntu it will install any needed OS dependencies.
- Wallet and puzzlehash generation have been refactored and simplified.
- Wallet has had various sync speed ups added.
- The rpc interfaces of all chia services have been refactored, simplified, and had various additional functionality added.
- Block timestamps are now stored in the wallet database. Both database versions were incremented and databases from previous versions will not work with Beta 14. However, upon re-sync all test chia since Beta 12 should appear in your wallet.
- All vestigial references to plots.yaml have been removed.

Fixed

- Temporary space required for each k size was updated with more accurate estimates.
- Tables in the README.MD were not rendering correctly on Pypi. Thanks again altendky.
- Chiapos issue where memory was spiking and increasing
- Fixed working space estimates so they are exact
- Log all errors in chiapos
- Fixed a bug that was causing Bluebox vdfs to fail.

Added

Changed

- Long_description_content_type is now set to improve chia-blockchian's Pypi entry. Thanks to altendky for this pull request.
- A minor edit was made to clarify that excessive was only related to trolling in the Code of Conduct document.

Fixed

- When starting the GUI from an installer or the command line on Linux, if you had not previously generated a key on your machine, the generate new key GUI would not launch and you would be stuck with a spinner.
- Farmer display now correctly displays balance.

Added

- Rate limited wallets can now have unspent and un-spendable funds clawed back by the Admin wallet.
- You can now backup your wallet related metadata in an encrypted and signed file to a free service from Chia Network at backup.chia.net. Simply having a backup of your private key will allow you to fully restore the state of your wallet including coloured coins, rate limited wallets, distributed identity wallets and many more. Your private key is used to automatically restore the last backup you saved to the Chia backup cloud service. This service is open source and ultimately you will be able to configure your backups to go to backup.chia.net, your own installation, or a third party's version of it.
- Added a Code of Conduct in CODE_OF_CONDUCT.md.
- Added a bug report template in `.github/ISSUE_TEMPLATE/bug_report.md`.

Changed

- This is a new blockchain as we changed how the default puzzle hashes are generated and previous coins would not be easy to spend. Plots made with Beta 8 and newer continue to work, but all previous test chia are left on the old chain and do not migrate over. Configuration data like plot directories automatically migrate in your `~/.chia` directory.
- Proof of Space now requires significantly less temp space to generate a new plot. A k=32 that used to require 524GiB now requires only 313GiB - generally a 40% decrease across all k sizes.
- When plotting, instead of 1 monolithic temp file, there are now 8 files - one for each of the 7 tables and one for sorting plot data. These files are deleted as the `-2` or `-d` final file is written so the final file can fit within the footprint of the temporary files on the same filesystem.
- We've made various additional CPU optimizations to the Proof of Space plotter that reduces plotting time by an additional 13%. These changes will also reduce CPU utilization in harvesting.
- We have ruled out k=30 for mainnet minimum plot size. k=31 may still make mainnet. k=32 and larger will be viable on mainnet.
- We moved to react-styleguidist to develop reusable components in isolation and better document the UI. Thanks to embiem for this pull request.
- Coloured coins have been updated to simplify them, remove 'a', and stop using an 'auditor'.
- clvm has been significantly changed to support the new coloured coins implementation.
- Bumped cryptography to 3.1. Cryptography is now publishing ARM64 binary wheels to PyPi so Raspberry Pi installs should be even easier.
- `chia init` now automatically discovers previous releases in each new release.

Fixed

- `chia show -w` should now more reliably work. Wallet balances should be more often correct.
- View -> Developer -> Developer Tools now correctly opens the developer tools. Thank you to roxaaams for this pull request!
- Fixed 'Receive Address' typo in Wallet. Thanks meurtn on Keybase.
- Fixed a typo in `chia show -w` with thanks to pyl on Keybase.
- In Windows the start menu item is now Chia Network and the icon in Add/Remove is updated.

Added

- The Chia UI now has a proper About menu entry that gives the various component versions and directs people to submit issues on GitHub. Thank you to freddiecoleman for this pull request!
- Ability to run only the farmer, wallet, or timelord services, for more advanced configurations (chia run farmer-only, wallet-only, timelord-only)

Changed

- To complement the new About menu, we have revamped all Electron menus and made them OS native. There are now direct links to the Wiki, Keybase, and FAQ in the Help menu.
- There are minor improvements to how working space is calculated and displayed by the plotter. The plotter also has additional debugging information in its output.
- Successful plots only have an atomic rename.

Fixed

- kOffsetSize should have been 10 bits and not 9. This was causing plots, especially larger plots, to fail with "Error 0". This bug was introduced in Beta 8 with the new plot file format.
- A bug in aiosqlite was causing tests to hang - especially on the ci. This may also have been causing wallet database corruption.
- `chia show -w` now correctly outputs all wallet types and balances from the local wallet.

Added

- Meet our new Rate Limited wallet. You can now fund a wallet from an Admin wallet that will set how many coins can be spent over a given range of blocks for a given User wallet. Once combined with on chain wallet recovery, this makes it much easier to secure your "spending money" wallet so that if it is compromised you have time to get most of the funds back before an attacker can steal them all. This wallet should be considered alpha in this release as additional fixes and functionality will be coming in subsequent releases.
- We've added unhardened HD keys to bls-signatures for the smart wallets that need them. We've added significant cross project testing to our BLS implementation.
- The python implementation of bls-signatures is now current to the new specification.
- `chia show -b` now returns plot public key and pool public key for each block.
- Added cbor2 binary wheels for ARM64 to the Chia simple site. Raspberry Pi should be just a little easier to install.

Changed

- Wallet addresses and other key related elements are now expressed in Chech32 which is the Chia implementation of [Bech32](https://github.com/bitcoin/bips/blob/master/bip-0173.mediawiki). All of your old wallet addresses will be replaced with the new Chech32 addresses. The only thing you can't do is send test chia between 1.8/1.9 and 1.10 software. Anyone who upgrades to 1.10 will keep their transactions and balances of test chia from the earlier two releases however.
- We added a first few enhancements to plotting speed. For a k=30 on a ramdisk with `-b 64 GiB` it results in an 11% speedup in overall plotting speed and a 23% improvement in phase 1 speed. Many more significant increases in plotting speed are in the works.
- The proof of space document in chiapos has been updated to the new format and edited for clarity. Additionally GitHub actions now has the on demand ability to create the PDF version.
- Relic has upstreamed our changes required for the IETF BLS standard. We now build directly from the Relic repository for all but Windows and will be migrating Windows in the next release.
- Minor improvements to the Coloured Coin wallet were integrated in advance of an upcoming re-factor.
- Smart wallet backup was upgraded to encrypt and sign the contents of the backup.

Fixed

- Proof of space plotting now correctly calculates the total working space used in the `-t` directory.
- `chia show -w` now displays a message when balances cannot be displayed instead of throwing an error. Thanks to freddiecoleman for this fix!
- Fix issue with shutting down full node (full node processes remained open, and caused a spinner when launching Chia)
- Various code review alerts for comparing to a wider type in chiapos were fixed. Additionally, unused code was removed from chiapos
- Benchmarking has been re-enabled in bls-signatures.
- Various node security vulnerabilities were addressed.
- Updated keyring, various GitHub actions, colorlog, cbor2, and clvm_tools.

Added

- See wallet balances in command line: `chia show -w`
- Retry opening invalid plots every 20 minutes (so you can copy a large plot into a plot directory.)
- We've added `chia keys sign` and `chia keys verify` to allow farmers to certify their ownership of keys.
- Windows BLS Signature library now uses libsodium for additional security.
- You can now backup and restore Smart Wallet metadata.
- Binary wheels for ARM64/aarch64 also build for python 3.7.
- See and remove plot directories from the UI and command line.
- You can now specify the memory buffer in UI.
- Optimized MPIR for Sandybridge and Ivybridge CPUs under Windows

Changed

- `chia start wallet-server` changed to `chia start wallet`, for consistency.
- All data size units are clarified to displayed in GiB instead of GB (powers of 1024 instead of 1000.)
- Better error messages for restoring wallet from mnemonic.

Fixed

- Fixed open_connection not being cancelled when node exits.
- Increase the robustness of node and wallet shutdown.
- Handle disconnection and reconnection of hard drives properly.
- Addressed pre-Haswell Windows signatures failing.
- MacOS, Linux x64, and Linux aarch64 were not correctly compiling libsodium in
the blspy/bls-signatures library.
- Removed outdated "200 plots" language from Plot tab.
- Fixed spelling error for "folder" on Plot tab.
- Various node dependency security vulnerabilities have been fixed.
- Request peers was not returning currently connected peers older than 1 day.
- Fixed timeout exception inheritance changes under python 3.8 (pull 13528)

Deprecated

- Removed legacy scripts such as chia-stop-server, chia-restart-harvester, etc.
