add(chain): Adds a `network_name` field to `testnet::Parameters` (#8411)
* minor cleanup and rename * Adds an empty NetworkParameters struct to Network::Testnet variant, updates production code. * Updates tests * Adds `NetworkKind` and uses it instead of `Network` in `HistoryTreeParts` and `transparent::Address` * Adds a [network.testnet_parameters] section to the config, uses `NetworkKind` as zebra_network::Config::network field type, and converts 'Network' to `NetworkKind` before serializing * Applies some suggestions from code review * Applies suggestions from code review * returns b58 prefix constants directly to remove From<NetworkKind> impl for zcash_primitives::consensus::Network * Applies more suggestions from code review. * moves conversions to zcash_primitives::consensus::Network to where they're used. * Apply suggestions from code review Co-authored-by: Marek <mail@marek.onl> * rename `network` variables and method names typed as NetworkKind to `network_kind` * use only test block heights for the network associated with them * Applies more suggestions from code review. * Rename `NetworkParameters` to `Parameters` and move it a new `testnet` module * adds activation heights field * updates stored test config, adds a quicker test for checking that stored configs can be parsed, adds an intermediate representation of activation heights * implement Parameters for Network * Passes &Network directly instead of converting to zp_consensus::Network where there were conversions * fixes a bad merge (removes a network conversion in zcash_note_encryption) * Adds a test for the Parameters impl for zebra_chain::Network * fixes doc links * - Makes the `activation_heights` config field optional by adding a #[serde(default)] - Panics if a non-zero activation height is provided for the `Genesis` network upgrade - Always sets the `Genesis` and `BeforeOverwinter` network upgrade activation heights to 0 and 1, `BeforeOverwinter` could be overwritten by a later network upgrade - Makes the `activation_heights` field on `Parameters` private, adds/uses an accessor method instead, and adds a builder struct and `build()` method * small refactor of activation_heights() method * check that activation heights are in the right order * Updates `NetworkUpgrade::activation_height()` to return the height of the next NetworkUpgrade if it doesn't find the activation height of `&self` * checks that the miner address is of TestnetKind on Regtest and update assertion message * Adds a DNetworkUpgradeActivationHeights struct for better control over how activation heights can be configured * moves all ordered network upgrades to a constant, adds a no_duplicates test, moves struct with activation heights outside deserialization impl and accepts it in `ParametersBuilder::activation_heights()` instead of a Vec * panics if any network upgrades are configured to activate at Height(0) because it's reserved for Genesis * Simplifies the `ParametersBuilder::activation_heights()` method and removes an unnecessary test. * Adds Sapling HRPs as fields on testnet params. (#8398) * Applies suggestions from code review. * Update zebra-chain/src/parameters/network_upgrade.rs Co-authored-by: Marek <mail@marek.onl> * Adds `network_name` field and accessor method on `Parameters`, uses it in the `Display` impl for `Network` * Removes unnecessary `.filter()` * adds constraints on valid network names and a test * adds config field for setting network name, adds "with_" prefix to ParameterBuilder setter methods * Adds `MainnetKind`, `TestnetKind`, and `RegtestKind` to reserved network names * updates stored test configs and fixes `network_name()` docs --------- Co-authored-by: Marek <mail@marek.onl>
