So you need to broadcast an alert... | |
... here's what to do: | |
1. Copy sendalert.cpp into your bitcoind build directory | |
2. Decrypt the alert keys | |
copy the decrypted file as alertkeys.h into the src/ directory. | |
3. Modify the alert parameters in sendalert.cpp |

All of the BnB simulation results. Some are right, others are wrong.
All of the valid results for varying fee rate simulations, but readable

The Alert System previously utilized by Bitcoin has several issues (some of which may be classified as vulnerabilities). These issues no longer exist in Bitcoin as of network protocol version 700013 which was released with Bitcoin Core 0.13.0. Many altcoins and Bitcoin client implementations were notified of the Alert System's removal and have since removed the alert system themselves or transitioned to using an Alert system that does not share an Alert Key with Bitcoin.
All of the issues described below allow an attacker in possession of the Alert Key to perform a Denial of Service attack on nodes that still support the Alert system. These issues involve the exhaustion of memory which causes node software to crash or be killed due to excessive memory usage.
Many of these issues were not known until the Alert System was removed as developers inspected the code for vulnerabilities prior to releasing the Alert Key. Due to these issues, the publicat
