Dear participants of the Monero ecosystem,
|
|
|
|
We would like to inform you that we will be phasing out long payment
|
|
IDs this year. Long payment IDs are detrimental to privacy and a
|
|
source of negative user experience (as well as additional support work
|
|
for services). Services will have to upgrade to either integrated
|
|
addresses or subaddresses. Note, however, that there is some
|
|
discussion about phasing out integrated addresses as well. Therefore,
|
|
services are, to avoid having to potentially perform additional work,
|
|
encouraged to upgrade to subaddresses directly.
|
|
|
|
Long payment IDs will be phased out because they have several salient
|
|
drawbacks. First, long payment IDs are detrimental to privacy insofar
|
|
as they can potentially link the transactions of a user in case of
|
|
reusage. Second, long payment IDs have to be attached separately to a
|
|
transaction. This is inconsistent with conventional cryptocurrency
|
|
transactions and therefore unintuitive for the user. As a result,
|
|
users occasionally forget to attach the long payment ID when sending
|
|
their transaction to a service and thus have to go through support to
|
|
'recover' their funds. Third, it logically follows from the previous
|
|
point that long payment IDs cause additional support work for
|
|
services. Fourth, only one long payment ID can be attached to a
|
|
transaction. Thus, services cannot batch withdrawals of multiple users
|
|
specifying a long payment ID. By contrast, subaddresses have no such
|
|
restriction and withdrawals can thus all be batched.
|
|
|
|
In sum, payment IDs have serveral salient drawbacks and will therefore
|
|
be phased out. Services are recommended to upgrade to subaddresses as
|
|
soon as possible. Subaddresses essentially function similar to Bitcoin
|
|
HD wallets and should thus be relatively straightforward to implement.
|
|
Furthermore, subaddresses are managable from a resource point point of
|
|
view.
|
|
|
|
Yours sincerely,
|
