From c599b56f2c9b874e48bd00692d200bfd2c1bb443 Mon Sep 17 00:00:00 2001 From: j-berman Date: Mon, 4 Oct 2021 20:12:23 -0700 Subject: [PATCH] Decrease the "recent spend window" in gamma re-select to 15 blocks - combined with patching integer truncation (#7798), this gets the algorithm marginally closer to mirroring empirically observed output ages - 50 was originally chosen assuming integer truncation would remain in the client for that client release version. But patching integer truncation causes the client to select more outputs in the 10-100 block range, and therefore the benefit of choosing a larger recent spend window of 50 has less merit - 15 seems well-suited to cover the somewhat sizable observable gap in the early window of blocks --- src/wallet/wallet2.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/wallet/wallet2.cpp b/src/wallet/wallet2.cpp index ef0eb736a..dc6522c56 100644 --- a/src/wallet/wallet2.cpp +++ b/src/wallet/wallet2.cpp @@ -143,7 +143,7 @@ using namespace cryptonote; #define IGNORE_LONG_PAYMENT_ID_FROM_BLOCK_VERSION 12 #define DEFAULT_UNLOCK_TIME (CRYPTONOTE_DEFAULT_TX_SPENDABLE_AGE * DIFFICULTY_TARGET_V2) -#define RECENT_SPEND_WINDOW (50 * DIFFICULTY_TARGET_V2) +#define RECENT_SPEND_WINDOW (15 * DIFFICULTY_TARGET_V2) static const std::string MULTISIG_SIGNATURE_MAGIC = "SigMultisigPkV1"; static const std::string MULTISIG_EXTRA_INFO_MAGIC = "MultisigxV1";
