Succinct non-interactive arguments of knowledge, and the proof systems and linear-proof abstractions behind them.

	dv-SNARG, One Group Element Numbered Conjecture 1.3 of the source. Its own theorems achieve one group element plus O(tau) bits, and (with a random oracle) one group element, one hash output and about 2 tau bits; the conjecture halves the additive term to tau + o(tau) and asks for no random oracle. 4 open	Generic Group Model Proof Size Lower Bounds Snarksggmcharacterization
	DPP Field Size The small-field regime is settled: soundness Theta(1/sqrt q) is achieved and proved optimal. In the large-field regime the source achieves soundness eps for every prime p at least Omega~(S^9/eps6) and states in as many words that it believes the S-dependence is not tight. 4 open	Linear Pcps Snarkstight-boundadaptation (ai)
	No 2-element split NILPs A submitted construction gives a two-element split NILP for Boolean circuit satisfiability in the plain generic Type-III bilinear-group model; proof review and formalization remain open. 2 open	Generic Group Model Proof Size Lower Bounds Snarksimpossibilityresearch-solved
	RS Proximity Gaps to Capacity Proved up to the Johnson/Guruswami-Sudan bound delta < 1 - sqrt(rho); conjectured up to capacity delta <= 1 - rho - eta. The source records that nothing known contradicts c1 = c2 = 2, and that in characteristic greater than the degree nothing known contradicts c1 = c2 = 1 – while those smaller exponents are provably ruled out in characteristic two. 5 open	Proximity Testing Reed Solomon Codes Snarkstight-boundbarrier (ai)
	SSS Implies Fiat-Shamir Friendly Conjecture 1.3 of the source. It is explicit that it does not prove it – ‘only conjecture it’ – and asks for the proof or refutation as an important open problem. It does prove that SSS implies straight-line soundness, hence post-quantum soundness, and that its own instantiation of Kilian’s protocol is SSS. 4 open	Commitment Schemes Fiat Shamir Snarkscharacterization
