* Moved keyring handling into a KeyringWrapper class * Update click to 8.0.x for prompt_required support * Renamed KeyringWrapper to _KeyringWrapper * Expose password management options on Linux * CLI support for setting/removing a password * Global option for specifying the master password * Cache the password instead of setting on the context * Password bootstrapping during chia init * Tidying up _KeyringWraper's interface * Initial pass migrating the legacy keyring contents * Encryption/decryption of keyring.yaml contents * FileKeyring backend encrypts with ChaCha20Poly1305 * Tightened up keyring migration and initialization * Fixed issues identified by linters * Remove root_path from Keychain * Prevent double-migration if setting master passwd * KeyringWrapper tests are mostly complete * FileKeyring will now honor the service param * Tests for get/set/delete password * Formatting/commenting updates * Writer lock support with tests - WIP * keyring.yaml is now watched for modifications * Reader/Writer lock for get/delete password * Fixed linter issues * Reader lock tests * Formatting update * Hook up CHIA_ROOT support for KeychainWrapper * Quick fix to address test failures * Fixed failures when existing legacy keyring exists * Fixed test failures caused by reusing the same temp dir * keyring.yaml now lives in ~/.chia_keys by default. Can be overridden with CHIA_KEYS_ROOT or --keys-root-path * Fixed migration failure when setting a password (not using the default) * KeyringWrapper now uses supports_keyring_password to determine if a FileKeyring should be used. Patched tests to work regardless of whether supports_keyring_password return False * The daemon now takes a --have-gui option that will prevent calling check_keys() during startup. If the keyring is locked, we want the GUI to prompt for the password. * Added is_keyring_locked RPC call * Added 'unlock_keyring' RPC command * Added KeychainProxy and KeychainServer to handle RPC messages related to keyring operations. WalletNode no longer directly accesses the Keychain class. * Turn on macOS support for testing keyring passwords * Fixed get_key_for_fingerprint to use the ocal keychain if the platform doesn't need to remotely access the daemon's keychain. Fixed key reconstruction when sent over RPC. * Farmer now accesses the keychain over RPC * Fixes for linter issues and some restructuring to support tests that use setup_nodes.py * Couple of fixes to unblock the GUI from launching when a keyring password is set * Added a keychain RPC call for add_private_key() * Added remaining keychain proxy RPC calls for delete_key_by_fingerprint and delete_all_keys * Check for None when inspecting request arguments * Run check_keys after unlocking the keyring when the daemon is launched via GUI * Added check_keys RPC method. Fixed deserialization of key entropy in get_all_private_keys. This was preventing the GUI from being able to show key details. * Added get_first_private_key to keychain_server/proxy. create_plots now uses the keychain proxy when launched from the daemon. * Added a comment about KeychainProxy in chia plots check * Workaround import conflict when importing from 'tests.*' due to fasteners name conflict * Simulator now uses KeychainProxy if launched by the daemon. KeychainServer/Proxy now takes keychain user/testing params for testing scenarios. * Added "set_keyring_passphrase" RPC message * Reworking KeychainProxy usage to handle local keychain tests and RPC keychain tests. * Replace my prior usage of asyncio.run() with asyncio.get_event_loop().run_until_complete() * Silencing file_keyring logging for the moment. * Updated tests to use test keychains and appropriate BlockTools construction BlockTools should now be created with create_block_tools(_async) to handle async scenarios. Updated block_tools to be async compatible Updated fasteners to fix installation of top-level 'tests' in site-packages * Added 'remove_keyring_passphrase' RPC message to the daemon Minor tweak to TempKeyring to default to some test params * Fixed linter issues * Remove flake8 ignore statement now that the fasteners module has been updated * Some initial renaming changes: password -> passphrase * Fixed wallet RPC issue where get_key_for_fingerprint wasn't awaited-upon. Fixed legacy keyring initialization (for migration scenarios) * Fixed improperly merged file * Fixed linter issues. More renaming. * Updated spots that were still using an incorrect keychain call * Renamed use_password_cache, obtain_current_password * Renamed supports_keyring_password * Renamed has_master_password * Renamed has_cached_password, get_cached_master_password * Linter fixes * Renamed master_password_is_valid * Renamed set_cached_master_password * Renamed set_master_password * Renamed remove_master_password * Renamed has_cached_master_password * Renaming in file_keyring and keyring_wrapper Updated default keyring payload used for tests * Renamed get_password Other renaming updates * Renamed set_password Other renaming updates * Renamed remaining password occurrences (where appropriate) * password -> passphrase * Added tests for setting an emoji and Japanese master passphrase * Attempt to notify the daemon when a keyring passphrase is set/updated/removed * Missed one password -> passphrase replacement. * Fixed some file synchronization issues found when running tests on macOS * Adjusted timeout values for test_writer_lock_reacquisition_failure for macOS. * Removed logging statements previously added for debugging * Prompt for keyring passphrase up-front when launching a service. Changed --have-gui flag to --wait-for-unlock * Updated set_keyring_passphrase RPC message to fix optional current_passphrase param when the keyring is using the default passphrase. * Minor test cleanup to deduplicate some code. * Fixed regression when setting a new master passphrase * Minor refactoring and docs/commenting updates * Renaming password -> passphrase went too far. Keyring backends use password terminology for compatibility with third party backends. * Disabling macOS support (previously added for testing only) * Disabling passphrase support in preparation for sending out the PR * Fixed improper merge (vscode didn't save changes during rebase) * Update chia/cmds/init_funcs.py Co-authored-by: Adam Kelly <338792+aqk@users.noreply.github.com> * skip_check_keys -> should_check_keys * Shuffling some imports around to break cycles reported by LGTM * Handle unlocking the daemon if it's already launched and waiting for unlock. * Replaced uses_keychain_proxy decorator in farmer.py. Fixed async usage of get_reward_targets. Linter/reformatting fixes * Replaced uses_keychain_proxy decorator with a clearer method. * Cleanup the temp keyring dir using shutil.rmtree() * Restored self._root_path (had been changed to self.root_path) * Minor cleanup * ensure_keychain_proxy() now throws if connect_to_keychain_and_validate() fails * Plot key resolution now yields a PlotKeys object which can be passed into create_plots. De-indented test_invalid_icc_sub_slot_vdf to keep git blame tidy. * Added 'keyring_status' daemon RPC message to support the GUI * Minor changes relating to PR feedback * Addressed more PR feedback (mostly type annotations) * Commented-out macOS file keyring usage. This can be re-enabled for testing purposes. * Addressed test failures that require multiple keyrings in the same process. Each TempKeyring will now set a custom KeyringWrapper instance. * Fixed logic for communicating user_passphrase_is_set in the keyring_status RPC response. * Updated type annotations and method signature for set_passphrase to expect a string instead of bytes. * Fixed Wallet RPC tests * Fixed full_node_store tests. BlockTools should be created using the create_block_tools(_async) function(s) * Fixed test failures in test_pool_rpc * Fixed test_daemon. After BlockTools.setup_plots is run, the config file needs to be re-read to refresh stale plot_directories. * Suppressing LGTM false positives regarding passphrase leakage in CLI error output. Seems that LGTM sees MIN_PASSPHRASE_LEN as sensitive data. * Second attempt at suppressing LGTM false positives * Third attempt at addressing LGTM false positives * Removed test_keyring_wrapper param from Keychain ctor. Test setup now sets the keyring_wrapper property directly. * Reformatting * More targeted update of the test config to refresh just the "plot_directories" value * More LGTM suppressions Co-authored-by: Adam Kelly <338792+aqk@users.noreply.github.com> Co-authored-by: wjblanke <wjb98672@gmail.com> |

Chia is a modern cryptocurrency built from scratch, designed to be efficient, decentralized, and secure. Here are some of the features and benefits:
- Proof of space and time based consensus which allows anyone to farm with commodity hardware
- Very easy to use full node and farmer GUI and cli (thousands of nodes active on mainnet)
- Simplified UTXO based transaction model, with small on-chain state
- Lisp-style Turing-complete functional programming language for money related use cases
- BLS keys and aggregate signatures (only one signature per block)
- Pooling protocol that allows farmers to have control of making blocks
- Support for light clients with fast, objective syncing
- A growing community of farmers and developers around the world
Please check out the wiki and FAQ for information on this project.
Python 3.7+ is required. Make sure your default python version is >=3.7
by typing python3.
If you are behind a NAT, it can be difficult for peers outside your subnet to reach you when they start up. You can enable UPnP on your router or add a NAT (for IPv4 but not IPv6) and firewall rules to allow TCP port 8444 access to your peer. These methods tend to be router make/model specific.
Most users should only install harvesters, farmers, plotter, full nodes, and wallets. Building Timelords and VDFs is for sophisticated users, in most environments. Chia Network and additional volunteers are running sufficient Timelords for consensus.
Installing
Install instructions are available in the INSTALL section of the chia-blockchain repository wiki.
Running
