Hi,
I=E2=80=99ve been doing some work lately to create a specification for =
bitcoin pointers.=20
They can be used to point to transactions, inputs, outputs or some =
internal items within them.
The proposals strive for simplicity and user friendliness over =
compactness or other attributes.
There are three proposals, each of which builds upon the previous one, =
namely:
a) Canonical Pointers
The basic proposal.They look like this example: btc@170.1/179-631-520
Here is a link to the Google Docs document -> =
https://docs.google.com/document/d/1PBN4wKFYtgvDxV4DrWUdNe9Xqmb8GVxoIGDKRk=
Y9Xr4/edit?usp=3Dsharing =
<https://docs.google.com/document/d/1PBN4wKFYtgvDxV4DrWUdNe9Xqmb8GVxoIGDKR=
kY9Xr4/edit?usp=3Dsharing>
b) Mnemonic Pointers=20
They build on Canonical Pointers and the dictionary provided in bip39 to =
use words instead of numbers.=20
The previous Canonical pointer can thus be expressed as btc@best.ability =
<mailto:btc@best.ability>/biology-exclude-donate
Here is a link to the Google Docs document -> =
https://docs.google.com/document/d/1wLK2_UrRzK0eshkDntUIbVlIdswzuHmYNELOeP=
DjtPY/edit?usp=3Dsharing =
<https://docs.google.com/document/d/1wLK2_UrRzK0eshkDntUIbVlIdswzuHmYNELOe=
PDjtPY/edit?usp=3Dsharing>
c) Domain Pointers=20
They build on the Domain Name Registration system to encode a pointer to =
a Canonical Pointer as in btc@example.com <mailto:btc@example.com>
Here is a link to the Google Docs document -> =
https://docs.google.com/document/d/1KY7rM090oKzGn8NAz4XFxQnfkyD5gs4V6vpbfd=
w92RM/edit?usp=3Dsharing =
<https://docs.google.com/document/d/1KY7rM090oKzGn8NAz4XFxQnfkyD5gs4V6vpbf=
dw92RM/edit?usp=3Dsharing>
I haven=E2=80=99t had any peer review yet, so it is very likely that =
some small or big problems can be found.=20
I=E2=80=99d welcome any feedback from the community.
Best regards,
