Constant relay_utils::STALL_TIMEOUT
source · pub const STALL_TIMEOUT: Duration;Expand description
Default relay loop stall timeout. If transactions generated by relay are immortal, then this timeout is used.
There are no any strict requirements on block time in Substrate. But we assume here that all Substrate-based chains will be designed to produce relatively fast (compared to the slowest blockchains) blocks. So 1 hour seems to be a good guess for (even congested) chains to mine transaction, or remove it from the pool.
