Immortality of datacarrier and datacarriersize Options

PR to undeprecate datacarrier and datacarriersize configuration options has been merged into Bitcoin Core and will be included in v30. The undeprecation simply removes warning messages when using these settings. Many Bitcoin Core Users still desire to use these configuration options and with no clear plan for deprecation it did not make sense to have deprecation warnings.

Sparrow Wallet Casts Spell of Silent Payments in v2.3.0 Release

This release adds support for sending to silent payment addresses. Silent payment addresses are a new form of static payment address, where the actual bitcoin address that you send to is determined from both the silent payment address and the transaction inputs. This means you can pay to the same silent payments address while ensuring bitcoin addresses are never reused. This both simplifies the payment experience and makes it more private, at the cost of increasing the burden on the recipient to scan incoming transactions for payments.

This release also supports BIP353, also known as DNS payment instructions. You can now pay to an address that looks similar to ₿user@domain.com, which resolves to a DNSSEC-signed bitcoin: URI. For privacy reasons it’s best to use only a silent payments address (and BOLT12 invoice) in the URI.

The (extremely grey) Tor Witch Hunt
