Hi,

This proposal was heavily mediatized, and severe mischaracterizations of th=
e change being proposed led to genuine concerns among the community. A bett=
er communication from my part could have avoided unnecessary worries among =
bitcoiners and a lot of wasted time to everybody.

In an attempt to right this wrong, i have collected objections community me=
mbers have raised across the board (on Github, the Bitcoin development mail=
ing list, X, podcasts, at conferences, ..) to address them in a single post=
.

I just posted to Delving Bitcoin addressing all concerns and objections i c=
ould get my hands on: https://delvingbitcoin.org/t/addressing-community-con=
cerns-and-objections-regarding-my-recent-proposal-to-relax-bitcoin-cores-st=
andardness-limits-on-op-return-outputs/1697. These are actual objections an=
d concerns raised by community members, taken literally with little or no r=
eformulation to address the precise statement.

Hi,<br>
<br>
Standardness rules exist for 3 mains reasons: mitigate DoS vectors, provide=
 upgrade hooks, or as a nudge to deter some usages.</div><div style=3D"font=
-family: Arial, sans-serif; font-size: 14px;"><br></div><div style=3D"font-=
family: Arial, sans-serif; font-size: 14px;">Bitcoin Core will by default o=
nly relay and mine transactions with at most a single OP_RETURN output, wit=
h a scriptPubKey no larger than 83 bytes. <span>This standardness rule fall=
s into the third category: it aims to mildly deter data storage while still=
 allowing a less harmful alternative than using non-provably-unspendable ou=
tputs.</span></div><div style=3D"font-family: Arial, sans-serif; font-size:=
 14px;"><span><br></span></div><div style=3D"font-family: Arial, sans-serif=
; font-size: 14px;">Developers are now designing constructions that work ar=
ound these limitations. An example is Clementine, the recently-announced Ci=
trea bridge, which uses unspendable Taproot outputs to store data in its "W=
atchtowerChallenge" transaction due to the standardness restrictions on the=
 size of OP_RETURNs[^0]. Meanwhile, we have witnessed in recent years that =
the nudge is ineffective to deter storing data onchain.</div><div style=3D"=
font-family: Arial, sans-serif; font-size: 14px;"><br></div><div style=3D"f=
ont-family: Arial, sans-serif; font-size: 14px;">Since the restrictions on =
the usage of OP_RETURN outputs encourage harmful practices while being inef=
fective in deterring unwanted usage, i propose to drop them. I suggest to s=
