teor 00de709dd8 impl From<U256> for ExpandedDifficulty 2020-10-15 08:31:18 +10:00
Jane Lusby e05103323e
Implement Async Script Verification RFC (#961) 
This commit begins the process of integrating `zcash_script` with the rest of the system for verifying scripts while syncing the block chain. It does so by adding the necessary support for looking up UTXOs from the state service and implements the first parts of the `script::Verifier` for looking up the necessary UTXOs in the state and then generating the necessary call to `zcash_script` to verify the script itself.

Block Subsidy and Founders Reward Amounts (#1051) 
* add general and founders reward subsidy modules
* validate founders reward

ZIP-1014 only applies to mainnet, where Canopy is at the first halving.
On testnet, Canopy is before the first halving, and the dev fund rules
apply from Canopy. (See ZIP-214.)
