I think you would need to enforce that the "highest work chain" is the one represented by the smallest hashes in this way, rather than the one represented by a direct sum of all blocks. 10:09 < bsm117532> Going back to the above discussion of the incomplete beta function, it's straightforward to formulate a likelihood function that one chain contains more work than the other. 10:10 < bsm117532> ...by examining only log(height) hashes and using the (corrected relative to Satoshi) incomplete beta function formulation. 10:11 < bsm117532> Such a client wouldn't actually care about retargets, only highest work. 10:13 < bsm117532> Making low difficulty blocks wouldn't help you, because the likelihood function built from the incomplete beta would rank the longer chain as lower work (unless it accidentally got lucky with a very small hash -- but we know the probability of that). 10:14 -!- BashCo_ [~BashCo@unaffiliated/bashco] has quit [Remote host closed the connection] 10:21 -!- CrazyLoaf [uid67551@gateway/web/irccloud.com/x-bbnqnvabmvgryxtz] has joined #bitcoin-wizards 10:23 -!- todaystomorrow [~none@2601:647:c803:21a0:11fa:ec9e:1c0e:df76] has joined #bitcoin-wizards 10:25 -!- jl2012 [uid133844@gateway/web/irccloud.com/x-uzgxjaekbtabdfbi] has quit [] 10:25 -!- jl2012_ [uid133844@gateway/web/irccloud.com/x-ekkdguoypspephow] has joined #bitcoin-wizards 10:26 -!- jl2012_ is now known as jl2012 10:27 -!- jl2012 [uid133844@gateway/web/irccloud.com/x-ekkdguoypspephow] has quit [Client Quit] 10:27 -!- jl2012 [uid133844@gateway/web/irccloud.com/x-ssgxrczwxchhoiex] has joined #bitcoin-wizards 10:41 -!- BashCo [~BashCo@unaffiliated/bashco] has joined #bitcoin-wizards 10:42 -!- jannes [~jannes@095-097-246-234.static.chello.nl] has quit [Quit: Leaving] 10:46 -!- paveljanik [~paveljani@79.98.72.176] has joined #bitcoin-wizards 10:46 -!- paveljanik [~paveljani@79.98.72.176] has quit [Changing host] 10:46 -!- paveljanik [~paveljani@unaffiliated/paveljanik] has joined #bitcoin-wizards 10:50 < andytoshi> bsm117532: amiller: in my mimblewimble paper i just had a merkle-sum-tree of blockheaders and their difficulty 10:51 < andytoshi> this is sufficient to prove the difficulty of any block in relation to that of any other block, to prove the cumulative difficulty before and after that block, etc 10:53 -!- BashCo_ [~BashCo@unaffiliated/bashco] has joined #bitcoin-wizards 10:57 -!- BashCo [~BashCo@unaffiliated/bashco] has quit [Ping timeout: 264 seconds] 10:58 < bsm117532> andytoshi: I can vaguely figure out what that means, but it could stand to have more exposition. 10:58 < bsm117532> So leaf nodes are ordered pairs (difficulty, txn Merkle root) no? 10:58 -!- BashCo [~BashCo@unaffiliated/bashco] has joined #bitcoin-wizards 10:59 < tromp_> they cld also store cumulative difficulty instead of difficulty 11:00 -!- BashCo_ [~BashCo@unaffiliated/bashco] has quit [Ping timeout: 240 seconds] 11:00 < bsm117532> I think they do. But this is a different security model than I described above, depending on consensus to build the tree correctly. Given a truncated tree ("merkle path") the truncation points cannot be independently verified to represent the correct amount of work, unless you have the entire tree. 11:02 < bsm117532> I tried for a while to find a way to make a data structure that had that property (using some magic known as "incremental hash functions") but I don't see a way to make it work. 11:03 < andytoshi> yeah, the tree has every blockheader and it sums the difficulties in each header, so the root has the total cumulative difficulty of the chain 11:04 < tromp_> with cumulative difficulty in the headers themselves, you don't need an additional field in the merkle tree of blocks 11:04 < andytoshi> yep, although every internal node in the tree needs to commit to the sum of the difficulties of its children 11:06 < tromp_> they already commit to what is in the leaves 11:06 < tromp_> including cumulative diificulties 11:07 < andytoshi> yes but to verifiy cumulative difficulty without downloading every leaf, you need to have commitments in the nodes 11:07 < andytoshi> this is the point of a merkle sum tree 11:07 < bsm117532> tromp_: What andytoshi describes is actually an incremental hash function. What you do is store the Merkle path to the most recent addition to the tree. You can dump the entire rest of the tree. From that last Merkle path, you can update the root by one block. 11:08 < tromp_> complete verification requires checking every single block header 11:08 < bsm117532> So it's log(n) storage for all nodes. 11:09 < bsm117532> tromp_ Yes O(height) to re-verify. 11:10 < andytoshi> tromp_: if you have cum difficulty commitments you can use them to get a proof-of-proof-of-work even with varying difficulty 11:11 < andytoshi> if somebody forges a leaf's difficulty (as the sumtree will force them to do if they're forging a node's difficulty) this is the same as not mining a block and forging a normal popow 11:11 < tromp_> is the powopow probabalistic? 11:11 < bsm117532> tromp_: yes 11:11 < andytoshi> yes 11:11 -!- blackwraith [~priidu@unaffiliated/priidu] has joined #bitcoin-wizards 11:12 < bsm117532> Though, Bitcoin's PoW is probabilistic too -- you don't know how much hashpower was *actually* used to generate a set of block headers. 11:12 < andytoshi> https://download.wpsoftware.net/bitcoin/wizardry/mimblewimble.pdf section 3, theorem 7 says what i'm saying 11:12 < tromp_> so i'm saying you can do that with a plain merkle tree on top of blocks with cumdiff 11:12 < andytoshi> i call the powopow a "compact chain" 11:12 < andytoshi> tromp_: if i give you a merkle path in that how can you know anything at all about other blocks' difficulty? 11:13 -!- blackwraith [~priidu@unaffiliated/priidu] has quit [Read error: Connection reset by peer] 11:13 < tromp_> any two merkle paths witness the cum diff in the corresponding range of blocks 11:13 < andytoshi> ...so the powopow requires you give me the headers of every "skipped" block, so there is no skipping at all? 11:14 < bsm117532> no...popow requires only the smallest block hash within a range. Using the correct statistics, this gives you a probability distribution for the hashrate used to generate it. 11:15 < tromp_> let me read your thm 7 ... 11:15 < andytoshi> bsm117532: how can anyone tell what the smallest block hash is without downloading the whole range (or using a sumtree)? 11:16 -!- blackwraith [~priidu@unaffiliated/priidu] has joined #bitcoin-wizards 11:17 < bsm117532> It would have to be committed to in the block header, so a client would download the popow with the most recent block header. 11:17 < bsm117532> Aaaand my argument about security models goes out the window. 11:19 < andytoshi> tromp_: section 3.3.1 i think is self-contained and has everything i'm trying to say 11:19 < tromp_> yes; i'm digesting that right now:) 11:21 < tromp_> is M around 2^80 for bitcoin now? 11:22 < tromp_> or 2^70? 11:23 < andytoshi> i'm not sure what you mean, M is the "real difficulty" of an individial block (vs the target difficulty which is the binary invalid/valid threshold) 11:24 < tromp_> ok. there's also the complicating implicit factor of 2^32 in bitcoin 11:24 < tromp_> but you're ignoring that 11:24 < andytoshi> correct 11:25 < tromp_> so each hash consumes all prior lesser hashes that combined are about as impressive 11:25 < bsm117532> andytoshi: Actually you don't need to sum work. For Poisson processes like this, it's statistically equivalent to just keep the smaller of the block hashes instead of computing their summed difficulty. In that way you could just propagate the smallest hash up the tree. This combines these two ideas... 11:26 < andytoshi> ah i gotch bsm117532 ... you can consider this as a "sum" where the sum function is min? 11:26 < bsm117532> correct 11:27 < bsm117532> This preserves the ability of a client to directly verify that the root hash actually represents a certain amount of work... 11:27 < gmaxwell> you can't compute exact work from that min and get the same result as a comparison the ordinary way. if you use lowest you allow the 'high variance attacks' 11:27 < gmaxwell> E.g. where you have a low but finite and non-trivial probablity you replace the whole chain with your one asic. :P 11:28 < bsm117532> high variance = high work, and we know exactly the probability of that. 11:28 < bsm117532> This idea can also be improved by presenting the smallest N hashes in a given subset, where the variance goes down as N goes up. 11:28 -!- Joseph__ [~NewLibert@2602:306:b8e0:8160:189d:8779:7b34:4f82] has quit [Ping timeout: 255 seconds] 11:28 < bsm117532> You can get lucky once, but getting lucky N times is exponentially suppressed. 11:32 < gmaxwell> bsm117532: but I extend an _existing_ chain, so all but one of the N is not mine. that procedure also has the problem that adding an additional block to a chain likely doesn't increase it's work. 11:33 < bsm117532> Variance is the right way to think about this gmaxwell. It's a pretty straightforward analysis to figure out how many hashes need to be presented. 11:34 < gmaxwell> the skiplist proofs do not have the problem that linear verifiers compute a different work from proof of proof readers. 11:35 < bsm117532> gmaxwell: But when you're adding one, you're comparing forks with equivalent history up to some point. It's the work done after the forking point that must be compared, not variance on the larger, historical blocks. (e.g. you can allow more variance on the larger set of old blocks) 11:37 < gmaxwell> Peer X offers you chain A, Peer Y offers you chain B -- each offering a proof of how much work it takes. Which chain do you take? You must reach the same conclusion as nodes who verified blocks one at a time or you lose the game. 11:37 -!- Sosumi [~Leon@bl10-113-190.dsl.telepac.pt] has joined #bitcoin-wizards 11:37 -!- Joseph__ [~NewLibert@2602:306:b8e0:8160:c092:439b:71e3:67d1] has joined #bitcoin-wizards 11:38 < bsm117532> I guess what I'm meandering towards is that I think there exists another definition of "highest work" which can be verified by presenting log(height) hashes, and cannot be contradicted by the full history. (Or, full-history nodes would accept this other definition and not the work-sum Satoshi used) 11:41 < gmaxwell> then you're needlessly creating a vulnerablity where an attacker with a couple lucky blocks can replace the whole chain, with much higher probablity of success than the current system. Already the current system has P=1 of attacker success in finite but astronomically large time if the attacker maintains any constant proportion of hashpower and hashpower increases exponentially with any exponent 11:41 < gmaxwell> . 11:41 < gmaxwell> I would guess that a constant number of samples removes the 'exponentially with any exponent' from that result. 11:44 < bsm117532> I can compute how many "lucky blocks" he would need though, and incorporate that into the definition to kill this attack. 11:45 < tromp_> ok andytoshi, i fully see that the value of the compact block commitments 11:45 < tromp_> eh, remove "that" 11:46 < bsm117532> Another way to put it: given the oldest 2^n blocks, the subset of those blocks with the *largest* hashes can be truncated -- they don't prevent an attacker at all. 11:46 < andytoshi> awesome tromp_ ... with mimblewimble i had the additional constraint that i needed a "canonical" powopow because i wanted people to be able to drop blocks entirely, but i think what i came up with there is generally useful 11:48 -!- uiuc-slack [~uiuc-slac@li175-104.members.linode.com] has quit [Read error: Connection reset by peer] 11:48 -!- uiuc-slack [~uiuc-slac@li175-104.members.linode.com] has joined #bitcoin-wizards 11:48 < tromp_> did you ever compute the compact chain of bitcoin:-? 11:51 < andytoshi> no, i started to, but ran out of time working out that section of the paper and then i had to give a talk about it :( 11:51 < andytoshi> ..i'm very curious, though i then totally forgot to follow through on it.. 11:51 < tromp_> btw, is there much advantage to commiting to a merkle sum tree, rather than just the previous compact block? 11:52 < andytoshi> you don't know what the previous block is until you're done mining :) 11:52 < andytoshi> if not for that, no 11:52 < tromp_> since the compact chain is of only log length, can't every clinet be expected to have the whole chain in memory? 11:53 < andytoshi> yes, but i think for new verifiers to know that they got the canonical compact chain, you need the merkle sum-tree construction 11:53 -!- rusty2 [~rusty@pdpc/supporter/bronze/rusty] has joined #bitcoin-wizards 11:53 < andytoshi> maybe if you aren't doing pow-o-pow in consensus code you don't need this, i'm unsure 11:53 -!- Ylbam [uid99779@gateway/web/irccloud.com/x-udyakugufacqiesq] has quit [Quit: Connection closed for inactivity] 11:54 < tromp_> it seems everyone can quickly query for all block on compact chain if they dont already have them, and then they have no more need for the merkle sum tree 11:55 -!- nabu [~jm@192.40.88.73] has quit [Ping timeout: 252 seconds] 11:55 < andytoshi> the question is, without the tree, given only the compact chain, can you verify that this is the real chain (no) and does this affect the security model (i don't know) 11:55 < tromp_> we're talking about a chain of only a few hundred blocks right? 11:56 < andytoshi> yes 11:56 < andytoshi> ...but a few hundred, out of hundreds of thousands of blocks 11:57 < tromp_> but the tree is trivially computed from the chain?! 11:57 < tromp_> from the compact chain that is 11:58 < andytoshi> yes, but the chain doesn't commit to this tree 11:58 -!- rusty2 [~rusty@pdpc/supporter/bronze/rusty] has quit [Ping timeout: 268 seconds] 11:58 < tromp_> it does implicitly through all the commitments to prev compact block 11:59 < andytoshi> how does it commit to the prev compact block without committing to all of them? 12:00 < tromp_> i suggest prev compact block hash as a header field 12:00 < tromp_> instead of compact merkle sum tree hash 12:00 < andytoshi> you can't tell what the previous block us until you've mined the current one 12:01 < tromp_> yes, that would be a field like nonce that is not hashed for header-hash purposes 12:02 < bsm117532> Hmmm...one generalization beyond using min() instead of sum() to reduce variance is to use an Order Statistic.
