According to @ItsDave_ADA, he will try fanout from Hydra to Cardano L1 and says he has not seen a successful demo of this yet himself. Source: https://twitter.com/ItsDave_ADA/status/1997082035513602335 For ADA traders, the statement highlights that, to the author's knowledge as of Dec 5, 2025, a successful Hydra L1 fanout demo has not been seen by him.

According to @ItsDave_ADA, a live round-robin trading loop between Broker A, Broker B and Market Maker C is running inside a single open Hydra head, source: @ItsDave_ADA. This live setup demonstrates multi-party order flow and market-making behavior executing within one Hydra head, relevant for low-latency DEX and on-chain order book designs on Cardano ADA, source: @ItsDave_ADA.

According to @ItsDave_ADA, a real UTxO-based high-frequency trading engine running inside a single open Cardano Hydra head achieved a burst throughput of 875 transactions per second on his laptop (source: @ItsDave_ADA on X). According to @ItsDave_ADA, the throughput figure was reached as a burst inside one Hydra head, highlighting performance for an HFT-style workload rather than base-layer metrics (source: @ItsDave_ADA on X). According to @ItsDave_ADA, the post did not include hardware specifications, sustained TPS, latency measurements, or reproducibility details, limiting independent verification from the tweet alone (source: @ItsDave_ADA on X).

According to @ItsDave_ADA, he scripted and brought online a full multi-party Hydra head after resetting the environment, configuring verification keys, restarting the stack, running the Init transaction, and committing three participants, confirming an end-to-end setup was achieved (source: @ItsDave_ADA on X, Dec 2, 2025, https://twitter.com/ItsDave_ADA/status/1995957350914474241). He added that he plans to open source what he can to improve Hydra adoption, indicating forthcoming code releases that others can use to replicate the process (source: @ItsDave_ADA on X, Dec 2, 2025, https://twitter.com/ItsDave_ADA/status/1995957350914474241). Hydra is Cardano’s layer-2 “head” protocol intended to scale transaction processing via off-chain state channels, providing low-latency settlement pathways relevant to ADA utility and network throughput, per official Hydra documentation (source: Hydra documentation by Input Output Global, https://hydra.family).

According to @ItsDave_ADA, a developer with no prior Hydra experience had a Hydra environment running in about 30 minutes on Cardano devnet, indicating a faster setup workflow for builders (source: @ItsDave_ADA, Nov 17, 2025). The developer manually created and funded three independent Hydra participants, seeded them, and successfully opened a Hydra Head on devnet, reporting a significantly improved developer experience versus earlier attempts (source: @ItsDave_ADA, Nov 17, 2025). For ADA-focused traders monitoring ecosystem execution, this user-reported devnet milestone evidences operational progress that can inform assessments of near-term developer activity within Cardano’s tooling stack (source: @ItsDave_ADA, Nov 17, 2025).
