Cornell Blockchain is voting FOR this proposal for the following reasons:
-
Gaining even a microsecond edge historically required huge capital expenditures to build custom, optimized node configurations and infrastructure. Legitimizing the Fast Feed as an official, open product shifts the competition away from expensive engineering setups to a standardized, permissionless API. Anyone paying the uniform ticket price gets the exact same low-latency data stream, democratizing access.
-
By giving propAMMs and liquidity providers earlier visibility into ordered transaction flow, the feed allows them to update their quotes before getting caught on the wrong side of a price shift. Mitigating the risk of stale quotes allows market makers to provide deeper liquidity and tighter spreads across Arbitrum, which directly translates to lower execution costs for everyday retail traders.
-
Directing 97% of subscription revenues back to the Arbitrum DAO Treasury–not leaking it to 3rd party investors– establishes a sustainable, non-inflationary revenue stream that supports the ecosystem without diluting token holders.
However, while the feed is permissionless to buy, it is financially exclusionary. If the bidding mechanism drives up the price substantially, small/medium developers will persistently operate in a slower, informationally damaged manner. To determine the impact , it would be interesting to monitor price spikes, as well as if everyday users are facing better or worse slippage/execution prices. This could show if the feed is being used defensively, or if it is being used by predatory bots to optimize execution at the expense of retail fills.
