That's right, all you need to broadcast is a small proof, a non-interactive

📝 Original message:I've been sharing a similar solution for the past 2 weeks. I think 2016
blocks is too much of a wait, I think we should look at the mean block size
during the last 60-120 minutes instead and avert any crisis caused by
transactional spikes that could well be caused by organic use of the
network (Madonna sells her next tour tickets on Bitcoin, OpenBazaar network
starts working as imagined, XYZ startup really kicks ass and succeeds in a
couple of major cities with major PR push)

Pseudo code in Python
https://gist.github.com/gubatron/143e431ee01158f27db4

My idea stems from a simple scalability metric that affects real users and
the desire to use Bitcoin:
Waiting times to get your transactions confirmed on the blockchain.
Anything past 45mins-1 hour should be unnacceptable.

Initially I wanted to measure the mean time for the transactions in blocks
to go from being sent by the user
(initial broadcast into mempools) until the transaction was effectively
confirmed on the blockchain, say for 2 blocks (acceptable 15~20mins)

When blocks get full, people start waiting unnaceptable times for their
transactions to come through
if they don't adjust their fees. The idea is to avoid that situation at all
costs and keep the network
churning to the extent of its capabilities, without pretending a certain
size will be right at some
point in time, nobody can predict the future, nobody can predict real
organic usage peaks
on an open financial network, not all sustained spikes will come from
spammers,
they will come from real world use as more and more people think of great
uses for Bitcoin.

I presented this idea to measure the mean wait time for transactions and I
was told
there's no way to reliably meassure such a number, there's no consensus
when transactions are still
in the mempool and wait times could be manipulated. Such an idea would have
to include new timestamp fields
on the transactions, or include the median wait time on the blockheader
(too complex, additional storage costs)

This is an iteration on the next thing I believe we can all agree is 100%
accurately measured, blocksize.
Full blocks are the cause why many transactions would have to be waiting in
the mempool, so we should be able
to also use the mean size of the blocks to determine if there's a
legitimate need to increase or reduce the
maximum blocksize.

The idea is simple, If blocks are starting to get full past a certain
threshold then we double the blocksize
limit starting the next block, if blocks remain within a healthy bound,
transaction wait times should be as
expected for everyone on the network, if blocks are not getting that full
and the mean goes below a certain
threshold then we half the maximum block size allowed until we reach the
level we need.
Similar to what we do with hashing difficulty, it's something you can't
predict, therefore no fixed limits,
or predicted limits should be established.

📝 Original message:"How then to end this XT madness?"

Instead of bashing on someone that has actually put a solution forward,
make your own fork and see if your ideas on how to solve the issue are any
better.

As of now, 1Mb blocks are pure madness, and people are voting over an 8mb
block increase every day that passes, even with a "useless project" like
you call it.

Go out there and see how bitcoin is actually used.

As a developer on the side lines, bitcoin holder, bitcoin entrepreneur, and
someone who thinks block size limits should be dynamic, I applaud Mike and
Co. for this initiative, some of us that have different ideas on how to
deal with the blocksize issue will certainly not be afraid of wasting time
sending patches to the Bitcoin XT project where it seems they're a bit more
open minded about this issue. I bet sending the same patch to Bitcoin-Core
would be rejected on the spot. Bitcoin XT, I hope, will give room to allow
for scalability, it seems the other camp is bent on using Bitcoin their own
way and their own way only and that's far more problematic because that
will allienate the entire user base eventually.

📝 Original message:- policy neutrality.
- It can't be censored.
- it can't be shut down
- and the rules cannot change from underneath you.

except it can be shutdown the minute it actually gets used by its inability
to scale.

what's the point of having all this if nobody can use it?
what's the point of going through all that energy and CO2 for a mere 24,000
transactions an hour?

It's clear that it's just a matter of time before it collapses.

Here's a simple proposal (concept) that doesn't pretend to set a fixed
block size limit as you can't ever know the demands the future will bring
https://gist.github.com/gubatron/143e431ee01158f27db4

We don't need to go as far as countries with hyper inflation trying to use
the technology to make it collapse, anybody here who has distributed
commercial/free end user software knows that any small company out there
installs more copies in a couple weeks than all the bitcoin users we have
at the moment, all we need is a single company/project with a decent amount
of users who are now enabled to transact directly on the blockchain to
screw it all up (perhaps OpenBazaar this winter could make this whole thing
come down, hopefully they'll take this debate and the current limitations
before their release, and boy are they coding nonstop on it now that they
got funded), the last of your fears should be a malicious government trying
to shut you down, for that to happen you must make an impact first, for now
this is a silly game in the grand scheme of things.

And you did sound pretty bad, all of his points were very valid and they
share the concern of many people, many investors, entrepreneurs putting
shitload of money, time and their lives on a much larger vision than that
of a network that does a mere 3,500 tx/hour, but some people seem to be
able to live in impossible or useless ideals.

It's simply irresponsible to not want to give the network a chance to grow
a bit more. Miners centralizing is inevitable given the POW based
consensus, hobbists-mining is only there for countries with very cheap
energy.

If things remain this way, this whole thing will be a massive failure and
it will probably take another decade before we can open our mouths about
cryptocurrencies, decentralization and what not, and this stubornness will
be the one policy that censored everyone, that shutdown everyone, that made
the immutable rules not matter.

Perhaps it will be Stellar what ends up delivering at this stubborn pace.

📝 Original message:> So if they dont care about decentralisation, they'll be happy using cheaper
off-chain systems, right?

You betcha! Just talk to a regular people and try to sell them on the
different scenarios.

They will start using something cheaper/faster the minute it comes along
from the banking industry, just to give you a real world example, this week
I've been dreading the idea of having to go to the bank to make a couple of
cash deposits. If I could open my bank's web page right now and do a very
simple interbank transaction (without having to convince the to let me link
their accounts to mine, with the process that takes like 2 days when they
deposit 2 different cent amounts...) just here within the retarded US
banking system... which has clearly realized the threat from
cryptocurrencies as evidenced on many banker conferences this year.

They will come up with ways to allow us to do person to person transfers,
but this will surely be limited to transactions within the country,
international remittances still have a great chance of being disrupted by
Bitcoin, if and only if, it will be cheap, otherwise the western unions and
xooms of the world will still rule.

Please get out of our your academic cocoon for a bit, talk to real people,
try to convince them to use Bitcoin, and think how hard it will be to make
the sell if on top you tell them... "it costs more... but it's
decentralized!" LOL

The competitive thing here is a deal breaker for a lot of people who have
no clue/don't care for decentralization, they just want to send money from

📝 Original message:I've been sharing a similar solution for the past 2 weeks. I think 2016
blocks is too much of a wait, I think we should look at the mean block size
during the last 60-120 minutes instead and avert any crisis caused by
transactional spikes that could well be caused by organic use of the
network (Madonna sells her next tour tickets on Bitcoin, OpenBazaar network
starts working as imagined, XYZ startup really kicks ass and succeeds in a
couple of major cities with major PR push)

Pseudo code in Python
https://gist.github.com/gubatron/143e431ee01158f27db4

My idea stems from a simple scalability metric that affects real users and
the desire to use Bitcoin:
Waiting times to get your transactions confirmed on the blockchain.
Anything past 45mins-1 hour should be unnacceptable.

Initially I wanted to measure the mean time for the transactions in blocks
to go from being sent by the user
(initial broadcast into mempools) until the transaction was effectively
confirmed on the blockchain, say for 2 blocks (acceptable 15~20mins)

When blocks get full, people start waiting unnaceptable times for their
transactions to come through
if they don't adjust their fees. The idea is to avoid that situation at all
costs and keep the network
churning to the extent of its capabilities, without pretending a certain
size will be right at some
point in time, nobody can predict the future, nobody can predict real
organic usage peaks
on an open financial network, not all sustained spikes will come from
spammers,
they will come from real world use as more and more people think of great
uses for Bitcoin.

I presented this idea to measure the mean wait time for transactions and I
was told
there's no way to reliably meassure such a number, there's no consensus
when transactions are still
in the mempool and wait times could be manipulated. Such an idea would have
to include new timestamp fields
on the transactions, or include the median wait time on the blockheader
(too complex, additional storage costs)

This is an iteration on the next thing I believe we can all agree is 100%
accurately measured, blocksize.
Full blocks are the cause why many transactions would have to be waiting in
the mempool, so we should be able
to also use the mean size of the blocks to determine if there's a
legitimate need to increase or reduce the
maximum blocksize.

The idea is simple, If blocks are starting to get full past a certain
threshold then we double the blocksize
limit starting the next block, if blocks remain within a healthy bound,
transaction wait times should be as
expected for everyone on the network, if blocks are not getting that full
and the mean goes below a certain
threshold then we half the maximum block size allowed until we reach the
level we need.
Similar to what we do with hashing difficulty, it's something you can't
predict, therefore no fixed limits,
or predicted limits should be established.

Instead of bashing on someone that has actually put a solution forward,
make your own fork and see if your ideas on how to solve the issue are any
better.

As of now, 1Mb blocks are pure madness, and people are voting over an 8mb
block increase every day that passes, even with a "useless project" like
you call it.

Go out there and see how bitcoin is actually used.

📝 Original message:"I don’t think the concern here is so much that some people want to
increase block size. It’s the *way* in which this change is being pushed
that is deeply problematic."

As a developer on the side lines, bitcoin holder, bitcoin entrepreneur, and
someone who thinks block size limits should be dynamic, I applaud Mike and
Co. for this initiative, some of us that have different ideas on how to
deal with the blocksize issue will certainly not be afraid of wasting time
sending patches to the Bitcoin XT project where it seems they're a bit more
open minded about this issue. I bet sending the same patch to Bitcoin-Core
would be rejected on the spot. Bitcoin XT, I hope, will give room to allow
for scalability, it seems the other camp is bent on using Bitcoin their own
way and their own way only and that's far more problematic because that
will allienate the entire user base eventually.

off-chain systems, right?

You betcha! Just talk to a regular people and try to sell them on the
different scenarios.

They will start using something cheaper/faster the minute it comes along
from the banking industry, just to give you a real world example, this week
I've been dreading the idea of having to go to the bank to make a couple of
cash deposits. If I could open my bank's web page right now and do a very
simple interbank transaction (without having to convince the to let me link
their accounts to mine, with the process that takes like 2 days when they
deposit 2 different cent amounts...) just here within the retarded US
banking system... which has clearly realized the threat from
cryptocurrencies as evidenced on many banker conferences this year.

They will come up with ways to allow us to do person to person transfers,
but this will surely be limited to transactions within the country,
international remittances still have a great chance of being disrupted by
Bitcoin, if and only if, it will be cheap, otherwise the western unions and
xooms of the world will still rule.

Please get out of our your academic cocoon for a bit, talk to real people,
try to convince them to use Bitcoin, and think how hard it will be to make
the sell if on top you tell them... "it costs more... but it's
decentralized!" LOL

The competitive thing here is a deal breaker for a lot of people who have
no clue/don't care for decentralization, they just want to send money from
A to B, like email.

📝 Original message:When blocks are found under or over the 10 minute threshold, hashing
difficulty is raised or reduced dinamically to keep a balance. This
intelligent measure has avoided us having discussions and kept a balance.

The same way you can't assume how much hashpower there will be to find the
next blocks, why can't we have a
function that adapts to the transactional volume on the blockchain, one
which allows us to grow/shrink an acceptable maximum block size. We're not
putting caps on processing, why should we put a date based cap on
transactional volume per block? You can't predict the future, but you can
look at what's happened recently to correct these limits.

Such function/filter should be able to recognize real sustained growth in
transactional volume and let us adjust the maximum accepted blocksize to
allow for the organic growth that will come due to real activity from
things like distributed market-places, decentralized bitcoin based services
(and all the things the community dreams about and might be building
already), truly decentralized technological breakthroughs that geniunely
need to use the blockchain. <Going the off-chain way only leads to
centralization and personal/corporate agendas, which to me goes against the
Bitcoin ethos>

It should be able to adapt fast enough so that we don't have episodes where
people need to wait 4 hours to days for transactions to get on the
blockchain and be confirmed. I believe proposals that include "every
100,000 blocks" are out of touch with reality, the blocksize needs to adapt
the same way blockdifficulty already adapts to growth or lack of hashing
power.

I'm not a statistician/mathematician, but I'm sure if we propose the
parameters that need to be considered for a realistic blocksize that
reflects the needs of the Bitcoin network users, there's plenty of
crypto/statistician/mathematician brain power to propose such filtering
function here.

Things that could be considered:
- median number of transactions per block (between 6 to 12 hours, you
should be able to adjust to a real shopping sprint for instance, or huge
pop band/artist decides to sell concert tickets on Bitcoin)
- median fees offered per transaction (can we detect spammers)
- median blocksizes
- median size per transaction
- number of new addresses signing off transactions, number of addresses
we've already seen in the blockchain before (are these spammers creating
lots of new addresses to move around the same outputs, is there an
efficient way to detect the likelyhood of a transaction being spam? Bayes?
No clue, no mathematician)
- median velocity between which an address receives an input and sends it
to another one?
- more things I've no knowledge of since I'm not familiar with the details,
but could immediatly come to mind to the experts.

Mining Centralization is already happening due to its competitive nature,
we don't complain or try to force hashing limits, we shouldn't do the same
for storage. There will be no shortage of blockchain mirrors, and those
interested in running full nodes, will surely find a way to do so.

Then what's the point?
Isn't this supposed to be an Open transactional network, it doesn't matter
if you don't want that, what matters is what people want to do with it, and
there's nothing you can do to stop someone from opening a wallet and buying
a pizza with it, except the core of the problem you ask yourself about,
which is, the minute this goes mainstream and people get their wallets out
the whole thing will collapse, regardless of what you want the blockchain
for.

Why talk about the billions of unbanked and all the romantic vision if you
can't let them use their money however they want in a decentralized
fashion. Otherwise let's just go back to centralized banking because the
minute you want to put things off chain, you need an organization that will
need to respond to government regulation and that's the end for the
billions of unbanked to be part of the network.

📝 Original message:On the Chinese "Single's Day" (sort of like the american Black Friday)
according to MIT's Tech Review
<http://www.technologyreview.com/news/534001/alipay-leads-a-digital-finance-revolution-in-china/>;
magazine

"Alipay handled up to 2.85 million transactions per minute, and 54 percent
of its transactions are made via mobile device."

For a few weeks I've been reading the conversations about block sizes and
the experiments being done on the subject with larger blocks.

On the day with the most transactions, the Bitcoin block chain averages
about 73 transactions per minute. I kept wondering what blocksize we'd need
for handling 100,000 transactions per minute, and estimated that roughly
we'd need a blocksize of about 1300x times larger than what we have now, so
bigger than 1Gb block... but seeing the numbers Alipay gets to handle just
in China make me wonder how scalable is Bitcoin if it were to truly compete
with worldwide financial services.

If you were to include double the number Alipay can handle, you'd be
shooting about 6 million transactions per minute, or roughly 60 million
transactions per block.

If you average every transaction around 250 bytes, then you'd need ~15
Gigabytes per block to be broadcast and hashed by all the full nodes every
10 minutes, eating good 2Tb of storage daily... do miners have enough
bandwidth and CPU power to handle this?

are my scalability concerns absurd?

To get a grasp of how much that is: When you search projects with more than

You are one of the top open source projects, and you should be grateful for
