My mistake, apologies all.
- I honestly thought everyone just took the next available number and publ=
ished up their BIP's.
And, I see you have something of a master list.
As a suggestion, would it be worth considering linking to some of that info=
rmation in the list welcome email? Web search is not always your friend for=
locating everything relevant.
Regards,
Damian Williamson

> BIP 177: UTPFOTIB - Use Transaction Priority For Ordering Transactions In
> Blocks
>
>
> This BIP proposes to address the issue of transactional reliability in
> Bitcoin, where valid transactions may be stuck in the mempool for extende=
d
> periods.
>
>
> There are two key issues to be resolved:
>
>
> 1. The current transaction bandwidth limit.
> 2. The current ad-hoc methods of including transactions in blocks
> resulting in variable and confusing confirmation times for valid
> transactions, including transactions with a valid fee that may never
> confirm.
>
>
> It is important with any change to protect the value of fees as these wil=
l
> eventually be the only payment that miners receive. Rather than an auctio=
n
> model for limited bandwidth, the proposal results in a stable fee for
> priority service auction model.
>
>
> I will post the full proposal up on to my blog in the coming days and,
> re-review incorporating feedback that I have received on and off thread.
> It would not be true to suggest that all feedback received has been
> entirely positive although, most of it has been constructive.

In<br>
> Blocks<br>
> <br>
> <br>
> This BIP proposes to address the issue of transactional reliability in=
<br>
> Bitcoin, where valid transactions may be stuck in the mempool for exte=
nded<br>
> periods.<br>
> <br>
> <br>
> There are two key issues to be resolved:<br>
> <br>
> <br>
> 1. The current transaction bandwidth limit.<br>
> 2. The current ad-hoc methods of including transacti=
ons in blocks<br>
> resulting in variable and confusing confirmation times for valid<br>
> transactions, including transactions with a valid fee that may never<b=
r>
> confirm.<br>
> <br>
> <br>
> It is important with any change to protect the value of fees as these =
will<br>
> eventually be the only payment that miners receive. Rather than an auc=
tion<br>
> model for limited bandwidth, the proposal results in a stable fee for<=
br>
> priority service auction model.<br>
> <br>
> <br>
> I will post the full proposal up on to my blog in the coming days and,=
<br>
> re-review incorporating feedback that I have received on and off threa=
d.<br>
> It would not be true to suggest that all feedback received has been<br=
