What do you think about the use of checkpointing in BCHABC? What kinds of checkpointing are there? Has Bitcoin ever had a re-organization event?

NOTE: The chain reorganization event in Bitcoin that I mentioned at 3:03 was actually in March 2013. You can read the post-mortem (BIP-50) here: https://github.com/bitcoin/bips/blob/master/bip-0050.mediawiki

  1. @aantonop at 4:30 you use the phrase "they reconverge when one of them achieves higher hashrate". I think it's important to let people know that the longest proof-of-work wins, rather than the higher hashrate, because they will misuse the context of this statement and assume you can start from any proof-of-work and miners get consensus simply with the highest hashrate.

  2. Andreas, I have a question.

    What is the likeliness of paper bitcoin making it's appearance? Any possibility that investment banks might try to sell bitcoin certificates to their clients?

  3. I leave this comment with the hopes of effecting future search algorithms in such a way that this comment will bring more attention to your important plight of spreading knowledge about blockchain technology in an environment that can often be discourteous.

  4. Checkpoints shift power to the developers which in ABC's case is even worse as there is really only one developer, or more accurately one developer who is instructed by Roger Ver. Not even close to a decentralised project.

  5. There is no BCHABC chain – there is BCH or BSV they are two separate coins. BSV is a forked coin off BCH. Calling it BCHABC or BABcoin is just like calling it Bcash. I know that this can be confusing, but I would expect more from you ;-).
