Rusty Russell	c78afa9201	onchaind: use lowball fee instead of donating to miners. As of bitcoind 0.16.1, you can't send a single-input OP_RETURN output, as you get 'tx-too-small'. sendrawtx exit 26, gave error code: -26?error message:?tx-size-small (code 64)?' So instead we use the minimum fee we can, but otherwise ignore it and don't wait for it to be mined. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>	7 years ago

Rusty Russell	1764d6c907	grind_htlc_tx_fee: benchmark. Takes 15 seconds on my laptop to do the worst-case grind: $ onchaind/test/run-grind_feerate 250001 250001 iterations in 15893 msec = 63574 nsec each It's not worth optimizing as it's 75% in libsecp: 29.65% run-grind_feera run-grind_feerate [.] secp256k1_fe_mul_inner 23.51% run-grind_feera run-grind_feerate [.] secp256k1_fe_sqr_inner 11.04% run-grind_feera run-grind_feerate [.] secp256k1_gej_double_var.part.6.constprop.34 9.56% run-grind_feera run-grind_feerate [.] secp256k1_scalar_reduce_512 5.70% run-grind_feera run-grind_feerate [.] Round Even forcing a compile with -O3 -flto, it's only 13883 msec = 55534 nsec each.
