[Bitcoin-development] comments on BIP 100

[Adam Back]

Hi

I made these comments elsewhere, but I think really we should be
having these kind of conversations here rather than scattered around.

These are about Jeff Garzik's outline draft BIP 100 I guess this is
the latest draft:  (One good thing about getting off SF would be
finally JGarzik's emails actually not getting blocked!).

http://gtf.org/garzik/bitcoin/BIP100-blocksizechangeproposal.pdf

may have changed since the original [1]

Over the original proposal:

1. there should be a hard cap, not indefinitely growing.

2. there should be  a growth limiter (no more than X%/year)

3. I think the miners should not be given a vote that has no costs to
cast, because their interests are not necessarily aligned with users
or businesses.

I think Greg Maxwell's difficulty adjust [2] is better here for that
reason.  It puts quadratic cost via higher difficulty for miners to
vote to increase block-size, which miners can profitably do if there
are transactions with fees available to justify it. There is also the
growth limiter as part of Greg's proposal. [3]

I think bitcoin will have to involve layering models that uplift
security to higher layers, but preserve security assurances, and
smart-contracts even, with protocols that improve the algorithmic
complexity beyond O(n^2) in users, like lightning, and there are
multiple other candidates with useful tradeoffs for various use-cases.

One thing that is concerning is that few in industry seem inclined to
take any development initiatives or even integrate a library.  I
suppose eventually that problem would self-correct as new startups
would make a more scalable wallet and services that are layer2 aware
and eat the lunch of the laggards.  But it will be helpful if we
expose companies to the back-pressure actually implied by an O(n^2)
scaling protocol and don't just immediately increase the block-size to
levels that are dangerous for decentralisation security, as an
interventionist subsidy to save them having to do basic integration
work.  Otherwise I think whichever any kind of kick the can some 2-5
years down the road we consider, we risk the whole saga repeating in a
few years, when no algorithmic progress has been made and even more
protocol inertia has set in.

Um, you mean except all the people who have built more scalable wallets
over the past few years, which is the only reason anyone can even use
Bitcoin from their phone? Or maybe you mean initiatives like Lightning ....
except StrawPay already developed something similar to the Lightning
network (complete with a working GUI wallet) and were ignored by
Blockstream as you prefer to write your own from scratch?

Sure, people in the industry take development initiatives. That doesn't
mean their work will be recognised on this mailing list.

"The laggards" being *everyone* who has already invested in building
Bitcoin software so far. Not a great way to frame things. Many of those
"laggards" have written orders of magnitude more code than you or Gregory
or Jeff, for instance.

I still think you guys don't recognise what you are actually asking for
here - scrapping virtually the entire existing investment in software,
wallets and tools.

Bitcoin does not have n-squared scaling. I really don't get where this idea
comes from. Computational complexity for the entire network is O(nm) where
n=transactions and m=fully validating nodes. There is no fixed
relationships between those two variables.

"Exposing the companies to back-pressure" sounds quite nice and gentle. Let
me rephrase it to be equivalent but perhaps more direct: you mean "breaking
the current software ecosystem to force people into a new, fictional system
that bears little resemblance to the Bitcoin we use today, whether they
want that or not".

As nothing that has been proposed so far (Lightning, merge mined chains,
extension blocks etc) has much chance of actual deployment any time soon,
that leaves raising the block size limit as the only possible path left.
Which is why there will soon be a fork that does it.

No slight intended obviously to people who do write actual client code.

That was probably insufficiently specific, let me rephrase: I am
referring to the trend that much of the industry is built on web2.0
technology using bitcoin via a library in a web scripting language,
often with consensus bugs, and even outsourcing and not even running
their own full node, so that the service itself offered to their users
isn't even SPV secure to the operator.  As well as being heavily based
on a third-party custody model that is the root cause of the repeated
wallet breaches.  Some of these companies have a noted tendency not to
upgrade or fix code.

So I mean this not to call out specific companies, but in the sense
that if we're technologists we should be trying to move the technology
forward, not just changing parameters which run into an O(n^2) scaling
wall or break decentralisation security.  And we shouldnt take the
above state of affairs as an immutable reality.  It can not persist
for bitcoin to reach maturity on scale nor security.

> I still think you guys don't recognise what you are actually asking for here

As I said I dont think we can expect Bitcoin to scale with no further
algorithmic improvements.  Algorithmic improvements take code.  There
is reasonable scope to build in an incrementally deployable way,
there's plenty of time for people to code, test and opt-in to things,
the sky is not falling.  Companies do care about scaling, and can
invest in the integration and coding implied to improve their products
scalability, they have an economic incentive to do it and there is no
scalable and safe way todo it without this work.

I am referring to global bandwidth O(n^2) with n=users, or O(n) per
user bandwidth cost to the system, while O(nm) is accurate nodes is an
internal system concept.  Anyway suffice to say the network does not
scale O(1) in per user cost.

A hard-fork takes a long period of time to deploy due to the
non-upgrade risk, people are working on things in the mean-time.
There can be a case for some increase to create some breathing room to
work on scaling and decentralising tech, I just mean to say that if we
do it in isolation, we're not focussing on the big picture.

OK, good to hear that. I'm not happy about the use of web technologies in
wallets/services either, but the causes of that trend are nothing to do
with block chain sizes. It's more because there's a generation of
developers who see no alternatives.

With projects like Lighthouse, I'm trying to show people that they can
blend the good bits of the web with the good bits of more traditional
client side development, at a cost they can afford.

Unfortunately, as you know, one of the reasons that developers turn to
outsourced services is that those services actually like developers and
give them the features they need. Whereas any attempt to add protocol
features for app/wallet developers to Bitcoin Core becomes controversial
due to some perceived or real lack of perfection.

I persevered for several months to add a very small "API" I needed for my
app to Bitcoin Core, and it was in the end a waste of time. There are no
actionable items left for the getutxo patch, regardless, I had to fork
Bitcoin to get it out there. It would have been *much* easier to just say,
fuck it, I'll use blockchain.info and in fact some in this community told
me to do exactly that. But, the approach I chose has been working fine for
months now.

Compare this experience to companies like chain.com, blockcypher etc - when
developers say jump, they say "how high?"

So It's unreasonable for the Bitcoin Core developer group to constantly
call developers building apps idiots or "non technical" (as I see so often
in this block size debate), and then complain that people don't write apps
in their preferred way! Just accept that decentralised app dev is already
hard, and the way Core is run makes it much harder still.


As I said I dont think we can expect Bitcoin to scale with no further
> algorithmic improvements.


A big part of the debate around this change is showing that this statement
is wrong. "Scaling" is not some kind of binary yes/no thing. It's a
continuous effort. You write a system that scales a certain amount, and
then if you find you need more capacity, you scale it again. Maybe that
 involves rewriting the existing code or maybe it just means improving what
you've got.

Or maybe (painful truth coming up) your product is not that compelling, or
times change and your users leave, and you discover you never actually need
to scale to the giddy heights originally envisioned.

A big part of the reason modern web dev is so messed up is that lots of
developers starting thinking every app they built needed to be "web scale"
from day one. SQL databases? Pah. Doesn't scale. Think big. We gotta no
NoSQL sharded key/value store from the start! Otherwise we're just showing
lack of confidence in our own product.

Then when they used up all their budget solving consistency bugs a
relational database would have avoided, they notice their competitors
sailing past them on a not-fully-scalable but certainly-scalable-enough
architecture that let them focus on features and making users happy.




> I am referring to global bandwidth O(n^2) with n=users


OK. O() notation normally refers to computational complexity, but ... I
still don't get it - the vast majority of users don't run relaying nodes
that take part in gossiping. They run web or SPV wallets. And the nodes
that do take part don't connect to every other node.

Alright - let's agree that we disagree on a few areas, like the relative
desirability of alternative non-blockchain designs - but we do seem to
agree that there is a case for an increase in the block size limit. That
seems like progress.

As you agree with that, what sort of schedule and time are you thinking of?
(well, by "you" I really mean blockstream because it's taking forever to
try and negotiate with every single person individually).

Since you keep bringing this up, I'll try to clarify this once again.

Since your patch was to enable querying spentness of particular outputs,
which is fundamentally unprovable data in Bitcoin as is (even your proposed
protocol that verifies scripts with amounts under sighash only proves
correctness of the txout data, not its spentness), I indeed don't see why
you would want anything else than querying such a service. I wish it were
different, but the choice is between querying a central service, or
trusting something a random peer on the internet tells you. At least with
the central service you can use an authenticated protocol with known keys
to detect MITM, and have someone to point to when they lie.

Not decentralized you say? Absolutely. But why do we want decentralization
in the first place? To remove central points of failure, and to reduce
trust. Bitcoin gets away with decentralization because it can validate (to
more or lesser extent) the data it received from its identityless peers. If
you can't do that, and are just aiming for removing central points of
failure, run a bunch of servers yourself, and let others run their own.
That sounds remarkably close to what you actually did, actually...

Do you want actually trustless querying of spentness in the future? Help
working on one of the several TXO commitment ideas to get them implemented.

I understand the arguments against it. And I think you are agreeing with me
- Adam is bemoaning the way developers outsource stuff to third party
services, and suggesting it is relevant to the block size debate. And we
are saying, no, it's happening because it's easier than doing things in a
decentralised way.

Right. There's a deeper issue here. The sort of 'trustless' querying of the
UTXO set that was demanded from me is impossible even with commitments,
because the answer can change the moment you receive it. All it takes is a
new block or new transaction to be broadcast a split second after you
download and use the data, and suddenly what you did is incorrect no matter
how many proofs you verified!

The only way to know this has happened is to be a full node and download
all transactions yourself ... and even then, you are trusting your peers to
actually relay you all transactions and not a subset. So in the end you can
never achieve perfection, only get closer to it.

But that situation is *fine* for many use cases, like showing someone a
snapshot of their crowdfund in a user interface. We just accept that what
we see on the screen may lag behind reality. It happens all the time with
all kinds of non-Bitcoin apps. We accept that there may be cases where the
answer we get is wrong. The software can nevertheless still be useful.

So Lighthouse compromises. It queries multiple peers and cross-references
their answers. If their answers don't match it shows an error on the screen
and won't show the user any status for their crowdfund at all. This error
has never occurred. Maybe one day it will. So the app gets more
decentralisation, more robustness, and accepts that the user interface
might one day show a wrong answer if the P2P network starts lying (or your
internet connection is hacked, but the right fix for that is P2P
encryption).

Unfortunately this sort of balance-of-risks approach is considered a
non-starter in Bitcoin Core. So why would developers even try? The message
sent was clear:  even if you have an approach you think will work, don't
bother.

Much easier to just outsource to a trusted service indeed.

The fact that using a centralized service is easier isn't a good reason
IMHO. It disregards the long-term, and introduces systemic risk.

But in cases where using a decentralized approach doesn't *add* anything, I
cannot reasonably promote it, and that's why I was against getutxos in the
P2P protocol.

Well sure, that's easy for you to say, but you have a salary :) Other
developers may find the incremental benefits of decentralisation low vs
adding additional features, for instance, and who is to say they are wrong?

It does add something though! It means, amongst other things, I can switch
of all my servers, walk away for good, discard this Mike Hearn pseudonym I
invented for Bitcoin and the app will still work :) Surely that is an
important part of being decentralised?

It also means that as the underlying protocol evolves over time, getutxos
can evolve along side it. P2P protocol gets encrypted/authenticated? Great,
one more additional bit of security. If one day miners commit to UTXO sets,
great, one more additional bit of security. When we start including input
values in the signature hash, great ... one more step up in security.

Anyway, I didn't really want to reopen this debate. I just point out that
third party services are quite happy to provide whatever developers need to
build great apps, even if doing so fails to meet some kind of perfect
cryptographic ideal. And that's why they're winning devs.

Now back to your regularly scheduled block size debates ...

My understanding of this debate is that there are some people who want to
keep Bitcoin at 1MB block limit, and there are some who want to increase it.

I for one am curious to see how 1MB limited bitcoin evolves, and I believe
we can all have a chance to see this AND hard-fork bitcoin to remove the
block size restriction.

To remove the 1MB limit required a hard fork. This is not disputed. It's
what we do with the original (1MB limit) bitcoin that concerns me (and
other's I am sure).

What I would like to see is both being allowed to live. Harry Potter and
Voldermort! (Except neither are evil!)

The solution is to hard-fork and merge-mine. This way, both can live, and
mining power is not divided.

Dogecoin recently hardforked and this hardfork also involved switching to
merge-mining, so it's been done successfully.

So, simply, bitcoin as it is doesn't need to actually fork, but instead, at
a certain block size, a forked bitcoin with the blocksize lmit removed will
start to be merge-mined alongside bitcoin. Miners can be ready for this.
Wallets can be ready for this - in fact, for most wallets and merchants
they will possibly want to default to the bigger blocksize fork since this
caters for more transactions per block.

We still don't know how removing the block limit will pan out and what
other problems with scalability will arise in the future, so by preserving
the original bitcoin, we keep diversity, and people won't feel their
investments in bitcoin are being unnecessarily put at risk (as their
investments will stay in both the new and the old bitcoin).

The bitcoin core developers can implement a patch like the one recently
used for dogecoin, to allow the chain to fork at a set point, where at
which point, bitcoins will be split into the new and the old. Branding will
be an important issue here I think, so that there is as little confusion as
possible. I think this is a small price to pay in return for not killing
the original bitcoin (even if it's true that Satoshi did intend to remove
the 1MB limit at some point).

If I'm missing something obvious please let me know.

[Bitcoin-development] The Bitcoin Node Market

[Raystonn .]

I have been toying with an idea and figured I'd run it by everyone here 
before investing further time in it.  The goal here is to make it 
sustainable, and perhaps profitable, to run full nodes on the Bitcoin 
Network in the long term.

- Nodes can participate in a market wherein they are paid by nodes, wallets, 
and other services to supply Bitcoin Network data.  Payment should be based 
on the cost imposed on the Node to do the work and send the data, but can be 
set in any way the node operator desires.  It's a free market.
- Nodes that are mostly leeching data from the Bitcoin Network, such as 
those that do not receive inbound connections to port 8333, will send 
payments to the nodes they connect to, but will likely receive no payments 
from other nodes, wallets, and other services.
- Nodes that are providing balanced full service to the Bitcoin Network will 
tend to have a balance of payments coming in and going out with regards to 
other balanced full service nodes, leaving them revenue neutral there.  But 
they will receive payments from leech nodes, wallets, and other services.

The net effect here is that the cost to run nodes will be shared by those 
who are using the Bitcoin network but not contributing by running a full 
node.  A market will develop for fees to connect to the Bitcoin Network 
which should help cover the cost of running the Network.  It's still 
possible to continue offering access to your node for free as there is 
nothing forcing you to charge a fee.  But this isn't very sustainable 
long-run.  Market efficiencies should eventually mean nodes take in only 
what is required to keep the Network operational.

Would SPV wallets have to pay to connect to the network too? From the
user's perspective, it would be somewhat upsetting (and confusing) to see
your balance slowly draining every time you open your wallet app. It would
also tie up outputs every time you open up your wallet. You may go to pay
for something in a coffee shop, only to find that you can't spend your
bitcoin because the wallet had to create a transaction to pay to sync with
the network.

Also, users of centralized wallet services like Coinbase would not have to
pay that fee; but users of native wallets like breadwallet would have no
such option. This incentivizes users to use centralized wallets.

So this is kind of imposing a worse user experience on users who want to
use bitcoin the "right" way. That doesn't seem like a good thing to me :/

SPV isn't the "right" way either ;)

If you're running a full node (the real "right way"), you should be able to 
earn more bitcoins than you pay out.

​Hah, fair enough, there is no such thing as the "right" way to do
anything. But I still think punishing users who use SPV wallets is ​a
less-than-ideal way to incentive people to run full nodes. Right now SPV is
the best way that exists for mobile phones to participate in the network in
a decentralized way. This proposal makes the user experience for mobile
wallets a little more confusing and annoying.

Re: [Bitcoin-development] The Bitcoin Node Market

[-- Attachment #1: Type: text/plain, Size: 2881 bytes --]

Just thinking off the top of my head here:

What if SPV wallets were exempt from the fee? Only full nodes would pay
other full nodes when initially sync'ing the blockchain. Then as long as
you keep your full node running for a long period of time, you'll
eventually make back the cost you paid to sync initially. This at least
incentives full node operators to keep their node running for as long as
possible once started.

This still imposes a worse UX on casual users who want full node security,
but don't want to run a server 24/7 (or perhaps simply aren't aware that
they have to). These users will watch their balance wither away each time
they open their wallet, but it would be very difficult to explain to them
why that is happening. It would just be frustrating and confusing.

Also, what happens when a user runs Bitcoin-QT for the first time after
downloading it to try it out? They wouldn't be able to sync the blockchain.
Even if the wallet has a balance, how would the wallet be able to see that
it has UTXO's without the ability to sync with the network for free?

We're planning to run our own full nodes to take load off the volunteer
network as breadwallet use increases, and also contribute any SPV serving
performance optimizations we can make to bitcoin-core. Just want to let
people know we share these concerns and have plans to mitigate any negative
impact on the network.

Suppose a billion mobile phones wanted to run SPV wallets tomorrow. Who 
would provide the nodes they would need connect to? The decentralization 
fairy?

There's absolutely no reason that paying for connectivity would be any 
more confusing or annoying than transaction fees are.

If some full nodes in the network started offering paid connection 
slots, that would just mean that users who checked the "pay subscription 
fee" box in their wallet configuration would have an easier time 
connecting than the users who did't, just like how your transaction 
might eventually get mined without a fee but paying one makes it faster 
and more probable.

How will the SPV wallet users pay for this service? With their money, or 
with their privacy?

With their money, if they were to take advantage of optional additional
financial services, like, as one example, comsumer protection insurance.

Alternate funding strategy: With 1billion users, mr roger ver is now among
the worlds first $trillionaires, and he generously donates to the
non-profit organization responsible for both the wildly popular wallet, and
his new found largess.

I would also guess that the cost to provide service to SPV wallets is
less than $0.01/mo per wallet and in any case less than long-term
transaction fees.  This can either be taken up by the wallet author or
transparently through a payment channel by the user.
