From 8db23df5810627661818fa378fa51f37208e0792 Mon Sep 17 00:00:00 2001 From: moneromooo-monero Date: Wed, 13 Jun 2018 12:16:07 +0100 Subject: wallet: on first refresh, start off with a quantized height for privacy reasons, so an untrusted node can't easily track wallets from IP address to IP address, etc. The granularity is 1024 blocks, which is about a day and a half. --- src/simplewallet/simplewallet.cpp | 4 +-- src/wallet/wallet2.cpp | 32 ++++++++++++++--------- src/wallet/wallet2.h | 11 ++++---- src/wallet/wallet_rpc_server.cpp | 4 +-- tests/functional_tests/transactions_flow_test.cpp | 14 +++++----- 5 files changed, 36 insertions(+), 29 deletions(-) diff --git a/src/simplewallet/simplewallet.cpp b/src/simplewallet/simplewallet.cpp index 4020793e9..af2afd12e 100644 --- a/src/simplewallet/simplewallet.cpp +++ b/src/simplewallet/simplewallet.cpp @@ -3885,7 +3885,7 @@ bool simple_wallet::refresh_main(uint64_t start_height, bool reset, bool is_init { m_in_manual_refresh.store(true, std::memory_order_relaxed);
