Bitcoin Core developers saw a mixed absorption from the Bitcoin assemblage arsenic they announced the merchandise of their v30 update, bringing guardant a big of node-related changes to architecture, performance, and security.
The cardinal changes brought guardant successful Bitcoin Core 30.0 are the instauration of optional encrypted connections betwixt nodes for amended privateness and the summation of the OP_RETURN information bounds wrong Bitcoin Core bundle from 80 to 100,000 bytes, enabling a importantly larger magnitude of non-financial information to beryllium embedded successful Bitcoin transactions.
“With the merchandise of this caller large version, versions 27.x and older are astatine ‘End of Life’ and volition nary longer person updates,” the Sunday announcement reads.

Such a immense displacement successful the information bounds enables the improvement of much blase and data-hungry decentralized applications connected the network, but has angered Bitcoin purists who reason that the web should beryllium utilized lone for fiscal transactions.

While this wasn’t a protocol change, the existent statement sparks memories of the artifact size wars of 2017, which yet led to a Bitcoin hard fork successful Bitcoin Cash.
Some spot the update arsenic a bully thing, specified arsenic Ark Labs Ecosystem Lead Alex Bergeron, who said via X connected Friday that helium intends “to usage each of the further OP_Return abstraction and WILL usage it to marque Bitcoin much similar Ethereum, but better.”

One workaround that a important fig of node operators person already been utilising is the alternate node bundle known arsenic “knots,” arsenic it enables them to enforce strict information size limits, specified arsenic 80 bytes, connected transactions.
“As a (hopefully) impermanent measure, tally Knots. I powerfully urge not upgrading to Core v30,” noted pioneer cryptographer Nick Szabo via X past week.

Earlier this month, Szabo raised concerns astir the ineligible implications of the information bounds increase, arsenic node operators tally the hazard of hosting “illegal data.”
“Without adding safeguards to let archival node operators to non-disruptively delete amerciable contented for which they volition often beryllium held criminally liable,” helium noted via X connected Oct. 2.
The laminitis of knots, Luke Dashjr, has not commented connected the update since it went live; however, helium has been captious of the latest Bitcoin Core update.
