1 2018-01-20 04:12:19 <mahamoti> suppose a block is broadcasted that would fork off a previous block.  it seems nodes can't immediately reject this because it might actually be that the fork is longer or becomes longer than what they currently think is longest chain, right?
 2 2018-01-20 04:13:03 <mahamoti> however, to validate the transactions in that block, since its not coming off the latest tip, they'd have to first get a state snapshot of the accounts of the prior node...
 3 2018-01-20 04:13:54 <mahamoti> and i would think they dont maintain state snapshots of the entire system account balances at every node.  so...does this mean that to validate it, they essentially have to apply every single transaction replayed from the start?
 4 2018-01-20 04:14:05 <mahamoti> and if so, could this not be used as a DOS attack against nodes?
 5 2018-01-20 07:14:25 <kallewoof> I don't think nodes validate blocks except the header until the chain would have more work then the current chain.

 7 2018-01-20 12:02:57 <GamerSg> Im having issues having my transactions confirming after abandontransaction
 8 2018-01-20 12:03:19 <GamerSg> it seems the network is not propagating transactions because they see it as a double spend
 9 2018-01-20 12:03:46 <GamerSg> abandoned transaction was RBF enabled
10 2018-01-20 12:05:18 <GamerSg> and now im reading that mempool expiry was increased to 2 weeks?? This makes abandontransaction useless
11 2018-01-20 14:43:48 <whatsupboy> any one have any experice with haskell towards any bitcoin development or related projects
12 2018-01-20 18:27:02 <nadav__> Hi! Is there a good getting-started document to read as a segway to begin (trying) to contribute to the project?
13 2018-01-20 18:28:25 <arubi> what do you want to read about?
14 2018-01-20 18:29:07 <arubi> nadav__, did you read https://bitcoin.org/bitcoin.pdf ?
15 2018-01-20 19:43:25 <Barrett> I'd like to create a colored coin, but without using those big frameworks out there
16 2018-01-20 19:43:39 <Barrett> something minimal for research purpose
17 2018-01-20 19:43:44 <Barrett> any idea where to start?
