An alternative perspective:
Replace By Fee is opt-in for attackers.
Replace By Fee is opt-out for victims.

Wanted: smart contracts for appointment timeliness. Penalize the counterparty for every TIME_UNIT they are late in fulfilling an obligation.

@kristovatlas Sure, but we have this “fee market” where when someone gets outbid, they are prevented from updating their bid. It’s lopsided.

@kristovatlas *shrugs* It’s a fundamental problem of not being able to predict the future. You could also argue CPFP could fix it.

via Twitter Web Client in reply to kristovatlas

@kristovatlas Yeah, when there are demand surges for block space. Core’s fee estimator lags since it uses past day or so of trailing data.

@ciscoguru @21 It’s hard to predict specifics because this is a platform for building a new type of market. siliconangle.com/blog/2015/09/2…

@khannib Right, right. Interesting - so far it’s a fair amount higher than I expected.

@ciscoguru I forsee mass adoption of @21 chips occurring when they are embedded in devices that natively use BTC; buyers may be oblivious.

@ciscoguru @21 Devs should be buying bitcoin computers to access the micropayment network rather than for the mining aspects.

@khannib Nice, so that’s # txs with an input w/sequence != UINT_MAX? I’d phrase it as “Transactions Opting In to RBF”

via Twitter Web Client in reply to khannib

@ciscoguru @21 Pretty sure large miners have to sell most of their coins to pay for operating expenses anyway.

@ciscoguru @21 Mining decentralization is more about preventing 51% attacks than about the distribution of the coins.

@ciscoguru In general, anyone whose business relies upon supporting higher number of users and transaction volume has a vested interest.

via Twitter Web Client in reply to lopp

@ciscoguru I’m not so sure that exchanges have /as/ much of an interest especially with the Liquid sidechain being released soon.

via Twitter Web Client in reply to lopp

@ciscoguru Mining centralization is certainly a justifiable fear, which is why I hope @21 succeeds in decentralizing mining again.

via Twitter Web Client in reply to ciscoguru

Point being, anyone who deals with unconfirmed transactions at the moment needs to take action to flag RBF-capable txs and act accordingly.

via Twitter Web Client in reply to lopp

As it stands, anyone sending a tx can “opt-in” to RBF by setting the sequence field on inputs to be < UINT_MAX. But receivers have to check.

via Twitter Web Client in reply to lopp

“Opt-In” Replace By Fee won’t be truly opt-in (agreed upon by both parties) until wallet software & payment processors update their logic.

via Twitter Web Client

@khannib Would it be hard to add stats of transactions opting in to replace-by-fee (inputs with sequence != 4294967295) to your site?

via Twitter Web Client

@kristovatlas They both appear to be problems to me, though the former exacerbates the latter.
