From 9cab267bfe6cc9f8cb9a952dddca31e6d8b6f21d Mon Sep 17 00:00:00 2001 From: mariari Date: Mon, 3 Jul 2023 21:12:41 +0800 Subject: [PATCH] masp: implement remaining inflation logic Inflation logic that works with 256-bit Amounts was deferred until now. We correct the implementation to adjust rewards for words above the lowest. (Rewards are only awarded in the lowest denomination of NAM, which is the only one used; if a reward exceeds i64::MAX, this is certainly an error.) For nonstandard (non-10^6) denominations, we must also perform an adjustment in decimal places. This will apply to ETH in reality, and our test ETH now. --- apps/src/lib/config/genesis.rs | 20 +- core/src/ledger/inflation.rs | 13 +- core/src/ledger/storage/masp_conversions.rs | 215 +++++++++++------ core/src/ledger/storage/mod.rs | 11 +- core/src/types/address.rs | 22 +- core/src/types/token.rs | 14 ++ core/src/types/token/parameters.rs | 21 +- genesis/dev.toml | 4 +- proof_of_stake/src/lib.rs | 9 +- tests/src/e2e/ledger_tests.rs | 248 +++++++++++++++++++- tests/src/e2e/setup.rs | 1 + wasm/checksums.json | 38 +-- 12 files changed, 462 insertions(+), 154 deletions(-) diff --git a/apps/src/lib/config/genesis.rs b/apps/src/lib/config/genesis.rs index 312c8e4a85..419f4aa370 100644 --- a/apps/src/lib/config/genesis.rs +++ b/apps/src/lib/config/genesis.rs @@ -15,6 +15,7 @@ use namada::types::key::dkg_session_keys::DkgPublicKey;
