Just a quick heads-up for those watching the list who may be using it - in the next Bitcoin Core release bloom filter serving will be turned off by default. This has been a long time coming, it's been an option for many releases and has been a well-known DoS vector for some time. As other DoS vectors have slowly been closed, this has become increasingly an obvious low-hanging fruit. Those who are using it should already have long been filtering for NODE_BLOOM-signaling nodes, and I don't anticipate those being gone any time particularly soon.
See-also PR at https://github.com/bitcoin/bitcoin/pull/16152 The release notes will liekly read: P2P Changes ----------- - The default value for the -peerbloomfilters configuration option (and, thus, NODE_BLOOM support) has been changed to false. This resolves well-known DoS vectors in Bitcoin Core, especially for nodes with spinning disks. It is not anticipated that this will result in a significant lack of availability of NODE_BLOOM-enabled nodes in the coming years, however, clients which rely on the availability of NODE_BLOOM-supporting nodes on the P2P network should consider the process of migrating to a more modern (and less trustful and privacy-violating) alternative over the coming years.
