<p>total number of buckets for tried addresses </p>
<p>Stochastic address manager</p>
<p>Design goals:</p><ul>
<li>Keep the address tables in-memory, and asynchronously dump the entire table to peers.dat.</li>
<li>Make sure no (localized) attacker can fill the entire table with his nodes/addresses.</li>
</ul>
<p>To that end:</p><ul>
<li>Addresses are organized into buckets.<ul>
<li>Addresses that have not yet been tried go into 1024 "new" buckets.<ul>
<li>Based on the address range (/16 for IPv4) of the source of information, 64 buckets are selected at random.</li>
<li>The actual bucket is chosen from one of these, based on the range in which the address itself is located.</li>
<li>One single address can occur in up to 8 different buckets to increase selection chances for addresses that are seen frequently. The chance for increasing this multiplicity decreases exponentially.</li>
<li>When adding a new address to a full bucket, a randomly chosen entry (with a bias favoring less recently seen ones) is removed from it first.</li>
</ul>
</li>
<li>Addresses of nodes that are known to be accessible go into 256 "tried" buckets.<ul>
<li>Each address range selects at random 8 of these buckets.</li>
<li>The actual bucket is chosen from one of these, based on the full address.</li>
<li>When adding a new good address to a full bucket, a randomly chosen entry (with a bias favoring less recently tried ones) is evicted from it, back to the "new" buckets.</li>
</ul>
</li>
<li>Bucket selection is based on cryptographic hashing, using a randomly-generated 256-bit key, which should not be observable by adversaries.</li>
<li>Several indexes are kept for high performance. Defining DEBUG_ADDRMAN will introduce frequent (and expensive) consistency checks for the entire data structure. </li>
</ul>
</li>
