Some of the more well-known forks have been around increasing the Bitcoin block size, which would impact the cost and time to process transactions. With few negative reports and significant potential fee savings for those wallets and services that support receiving to bech32 addresses, it may be time for more wallets to begin making bech32 their default address format. Although this advantage only benefits people spending from bech32 and other segwit addresses, it’s another reason to expect people and organizations will increasingly request your software and services pay bech32 addresses in the near future. We’ve previously discussed how much users and services can save by switching to native segwit (bech32) addresses, but we’ve only described that in terms of vbyte and percentage savings. If users of native segwit begin to save tens or hundreds of dollars per transaction, we expect there to be increased competitive pressure for high-frequency spenders such as exchanges to migrate to only accepting deposits using bech32 addresses.

Note that using a third-party service reveals to them that you have an interest in that transaction, possibly significantly reducing your privacy. For users and organizations who have a fixed maximum price they’re willing to pay in fees per transaction, using segwit could significantly reduce confirmation time for their transactions during periods of high activity. The last time bitcoin and PMs moved differently was in early 2022. Back then, gold, silver, and mining stocks moved higher in a visible manner, while bitcoin moved higher very modestly. More notably, many nodes continue to run old versions for years after newer versions have become available, so it’s expected that developers of wallets using bloom filters will have some time after the release of Bitcoin Core 0.19 (estimated late 2019) to find a replacement source of data. Users who still want to serve bloom filters can re-enable it. Early efforts to that end included adding a BIP111 services flag to indicate whether or not a node supports bloom filters so that clients can find supporting nodes, and a peerbloomfilters configuration option that allows node users to disable bloom filters in case they’re worried about the DoS attack. 15681 adds an exception to Bitcoin Core’s package limitation rules used to prevent CPU- and memory-wasting DoS attacks.

Monero (also known by its ticker "XMR") is an exception to this. Most notably, the proposal significantly reduces the byte size of messages through two mechanisms: schnorr signatures and optional message extensions. Optional message extensions using Type-Length-Value (TLV) records allow omitting unnecessary details when the protocol defaults are being used (for more information about TLV, see the notable code and youtu.be documentation changes section below). 607 extends the LN specification to allow packets to contain records that start with a type identifying their purpose, followed by the message length and the record’s value, called TLV records. All LN implementations monitored by Optech currently support TLV on at least their development branch. 16152 disables BIP37 bloom filter support by default. Additionally, bloom filter support was never updated for checking the contents of the new witness field after segwit was activated, making it less useful than it could be for segwit wallets. ● Gossip update proposal: Rusty Russell made a short proposal to update the gossip protocol that LN nodes use to announce what channels they have available for routing payments and what capabilities those channels currently support. ● Brainstorming just-in-time routing and free channel rebalancing: sometimes LN nodes receive a routed payment that they reject because their outbound channel for that payment doesn’t currently have a high enough balance to support it.

Rene Pickhardt previously proposed Just-In-Time (JIT) routing where the node would attempt to move funds into that channel from one or more of its other channel balances. Despite this, some wallets already default to bech32 addresses and others plan to move to use them soon, such as Bitcoin Core. For that reason and others (including privacy concerns) a number of Bitcoin Core contributors have wanted to disable the feature for several years now. We solicited input from a number of services including BitGo, BRD, Conio, Electrum, and Gemini regarding their customer support burden from use of bech32 addresses. Most services report minimal issues ("no support requests" and "there isn’t too much confusion"). Once the switch to Postgres was done, the dashboard graphs came up much faster in Grafana. There have never been many tickets on this subject either before or after Bech32 so not sure this is an important point in making the argument for exchanges to make the switch. Given that a very large percentage of daily Bitcoin transactions are deposits to exchanges, we would then expect wallets and services that don’t provide bech32 sending support to quickly fall out of favor with users.
