Here are three interesting papers all discussing how merchants can accept 0-conf payments and avoid double spends. All define 0-conf as "fast payments". I think we should fit this term into our vocabulary for BCH.

Abstract
The term near or weak blocks describes Bitcoin blocks whose PoW does not meet the required target difficulty to be considered valid under the regular consensus rules of the protocol. Near blocks are generally associated with protocol improvement proposals striving towards shorter transaction confirmation times. Existing proposals assume miners will act rationally based solely on intrinsic incentives arising from the adoption of these changes, such as earlier detection of blockchain forks.
In this paper we present Flux, a protocol extension for proof-of-work blockchains that leverages on near blocks, a new block reward distribution mechanism, and an improved branch selection policy to incentivize honest participation of miners. Our protocol reduces mining variance, improves the responsiveness of the underlying blockchain in terms of transaction processing, and can be deployed without conflicting modifications to the underlying base protocol as a velvet fork. We perform an initial analysis of selfish mining which suggests Flux not only provides security guarantees similar to pure Nakamoto consensus, but potentially renders selfish mining strategies less profitable.

PSA: Bitcoin used to have safe zero-confirmation (instant) transactions until Blockstream intentionally destroyed it.

Many people seem to be unaware that bitcoin previously had safe and instant transactions and easily still could if not for the misguided roadmap of Blockstream and the current Core team. It is also worth pointing out that the current "Core" team actually kicked out much of the original Core team such as Gavin, Jeff, and Mike, but managed to steal all of the good reputation they had built up for Core.

Coinbase bitcoin transfer still pending after over 20 hours! Does not appear on blockchain. "No transaction found with the hash..." (zero confirmations, zero response from Coinbase) ** Warning: Other Users Experiencing Same Issue **

I sent $900 worth of bitcoin out of my Coinbase wallet over 20 hours ago. Coinbase says the transaction is "pending," yet it has 0 confirmations, and doesn't even show up on the blockchain.
The link Coinbase provides for the "transaction" returns with: "No transaction found with the hash..."
I posted about this problem yesterday. Lots of other users experiencing the same problem. Of course, no response from Coinbase.
