this post here is causing unnecessary drama people are somewhat mad because the @Zcash account is educating the community on ongoing R&D by @ShieldedLabs (an independent zcash contributor) -- in a harmless post that clearly categorizes it as "proposed" some more context ⬇️ crosslink is a proposed hybrid pow/pos upgrade for zcash. nothing is decided. both research, development and community discussions are still ongoing. it keeps mining for block production and adds a parallel finality gadget so confirmed blocks become irreversible in practice. shielded labs is the independent swiss organization building it. founded in late 2022 by @aquietinvestor as a donation-funded group outside the development fund and block rewards. @zooko is CPO there. the team has former ECC and equilibrium people plus other protocol engineers. their whole point is to add independent capacity so Zcash is less dependent on any single US-based entity. that's great for decentralization! they published the crosslink roadmap in march 2025 and have been shipping prototype milestones since then (placeholders, disconnected BFT, PoW respecting finality, staking semantics). by early 2026 the prototype phase was done and they moved into incentivized feature nets and productionization. so roughly a year and a half of public implementation work on top of earlier design discussion. it matters because pure pow tends to centralize over time. bitcoin started with many miners of similar size and now two mining pools produce more than half the blocks. that's an inevitable outcome for the game theories behind BTC pow. i've written extensively about that (and others have too). larger operators get more rewards, buy more specialized hardware, and smaller ones get priced out by difficulty and energy costs. capital is tied to equipment that can be pointed at other chains or sold, so the network stake is weak. in a hybrid setup the pos side puts value at stake that is cumulative and locked to the network itself. an attacker has to compromise both layers. staking stays inside the shielded pool with batching and other privacy measures so individual positions are harder to fingerprint. finality also makes deposits, bridges, and everyday payments more predictable without waiting on probabilistic confirmations. transactions become faster and more aligned to real-world payment expectations. it does not replace PoW. it adds a complementary security model and better long-term sustainability as issuance declines, while expanding who can participate beyond a few large miners. that addresses the empirical centralization path pure proof-of-work has shown, without throwing away the base layer $ZEC already has. i support the direction. independent teams building in public and having their year-and-a-half work being recognized by a simple and harmless post that is now being weaponized by governance adversaries.
