From d640a3ceab4f4372c2a0f738c1286cfde4b41b50 Mon Sep 17 00:00:00 2001 From: Tom Harding Date: Wed, 25 Jun 2014 23:41:44 -0700 Subject: Relay double-spends, subject to anti-DOS Allows network wallets and other clients to see transactions that respend a prevout already spent in an unconfirmed transaction in this node's mempool. Knowledge of an attempted double-spend is of interest to recipients of the first spend. In some cases, it will allow these recipients to withhold goods or services upon being alerted of a double-spend that deprives them of payment. As before, respends are not added to the mempool. Anti-Denial-of-Service-Attack provisions: - Use a bloom filter to relay only one respend per mempool prevout - Rate-limit respend relays to a default of 100 thousand bytes/minute - Define tx2.IsEquivalentTo(tx1): equality when scriptSigs are not considered - Do not relay these equivalent transactions Remove an unused variable declaration in txmempool.cpp. --- src/init.cpp | 1 + 1 file changed, 1 insertion(+) (limited to 'src/init.cpp') diff --git a/src/init.cpp b/src/init.cpp index c7170b0f2..bd732753e 100644 --- a/src/init.cpp +++ b/src/init.cpp @@ -1175,6 +1175,7 @@ bool AppInit2(boost::thread_group& threadGroup) LogPrintf("mapAddressBook.size() = %u\n", pwalletMain ? pwalletMain->mapAddressBook.size() : 0); #endif + RegisterInternalSignals(); StartNode(threadGroup); if (fServer) StartRPCThreads(); -- cgit v1.2.3
