LEAD: SEACAST adds tests on larger simulated networks.
[1]
TEST EDITION | 29 October 2026
SEACAST author cskiraly published additional broadcast-protocol measurements on 29 October 2026.
[1] The update reports tests with more nodes and a second simulator.
[1]
cskiraly reports that simulations with 1,000 and 2,000 nodes took about a tenth longer than simulations with 500 nodes.
[1] He reports roughly unchanged byte counts across those network sizes.
[1] These are simulation results reported by the protocol's author, rather than measurements of Ethereum mainnet deployment.
[1]
SEACAST divides objects into coded chunks and forwards each chunk before receiving the complete object.
[2] Its design covers both complete-object broadcasts and delivery of samples requested by individual nodes.
[2] The original post separates measured implementations, specified rules, formal checks and proposed extensions.
[2]
The new update reports that Shadow simulations also put SEACAST ahead of gossipsub on speed and byte consumption across every tested network.
[1] cskiraly says corrected code leaves delivery times within the variation between runs.
[1] He reports slightly lower byte consumption on thinner links after those fixes.
[1]
The added comparison includes FullDAS with every node sampling every cell, a specific configuration rather than all possible sampling workloads.
[1] cskiraly reports SEACAST was faster and lighter across ten simulated networks of each tested kind.
[1] The original timing definition excludes proof checking, block waiting and decoding, limiting what these delivery figures establish.
