what is unlocked by the version of ethereum that finalizes 1gb of data per second? what is unlocked by a zkSNARK protocol with a 100x overhead on underlying computation?

OTOH, being forced to defend X as "shared infrastructure" today requires you to do some more argumentative heavy lifting - defining "shared infra," arguing where and why it's valuable, and why it's an appropriate descriptor X. (until "shared infra" is co-opted too, heh)

once you've memed something as reductive as Public Goods Are Good into the narrative, it becomes a target for grifters - disincentivizing nuance makes it easy for anyone to claim that what they're doing is "public goods," and therefore should be funded and awarded virtue points

commonly-used phrases in the discourse around popular topics take on connotational baggage that leave them vulnerable to being co-opted. fight intellectual laziness by switching terms every now and then - "shared infrastructure" vs "public goods," "proof systems" vs "zk crypto"

plasma and other off-chain DA solutions are still viable, but weren't a good fit for apps needing permissionless DA guarantees as strong as defi needs. i expect to see plasma-like constructions return for games / other lower-stakes use cases in 2023 (maybe app-specific plasmas)

all of these require info asymmetry, and therefore require ZK (or MPC, or something similar). privacy is important for ideological reasons, but even more fundamentally, information asymmetry is a *mechanic* that most complex coordination systems need to function. 3/3

necessary to allow anyone to permissionlessly make claims about this data at arbitrary levels of granularity. think ID and reputation systems, queries on public social graphs, fine-grained claims of creditworthiness, actions in digital games/virtual worlds... 2/

ZK (and similar primitives) is useful in any setting where you want to ensure that rules are being followed despite information asymmetry between participants. as more social, financial, governance, etc. data is uploaded (or hash-committed to) on-chain, ZK becomes 1/
