Big block support observer

[jl2012]

Objectives:
1. To follow the trend of big block approval / disapproval among full nodes
2. To follow the trend of big block approval / disapproval among miners
3. To follow the trend of big block approval / disapproval among major bitcoin economy players, holders, etc.
4. To discuss the strategy of soliciting support for big blocks (or otherwise)
5. This thread is not restricted to any specific big block client / BIP

Methods:
1. Follow the number of big block supporting full nodes, e.g. BitcoinXX
2. Follow the number of big block supporting blocks, e.g. version 0x20000007, coinbase message
3. Follow credible news source, twitter/reddit/forum accounts
4. Proof of stake signature. If you hold bitcoins and would like to voice out, please sign a statement with your address with bitcoin. Instructions

Rules:
1. This is a self-moderated thread. Posts violating the rules may be removed.
2. This thread is NOT for big block debate, including the discussion of pros and cons of different proposals and implementations. If you want to debate please go somewhere else. I believe there are plenty of places for this.
3. I don't want this tread being censored. Please avoid directly mentioning or linking any specific big block enabling bitcoin client. For sarcasm or not, call them BitcoinXX, Bitcoin**, BitcoinCensored, etc. Welcome to internet censorship (Based on the recent moderation style in this forum, this seems not necessary now)

This is a summary of big block proposals I posted earlier on the bitcoin-dev mailing list

Currently, there are 4 block size BIP by Bitcoin developers:

BIP100 by Jeff: http://gtf.org/garzik/bitcoin/BIP100-blocksizechangeproposal.pdf
BIP101 by Gavin: https://github.com/bitcoin/bips/blob/master/bip-0101.mediawiki
BIP102 by Jeff: https://github.com/bitcoin/bips/pull/173/files
BIP??? by Pieter (called "BIP103" below): https://gist.github.com/sipa/c65665fc360ca7a176a6

Should we use a miner voting mechanism to initiate the hardfork?
BIP100: Yes, support with 10800 out of last 12000 blocks (90%)
BIP101: Yes, support with 750 out of last 1000 blocks (75%)
BIP102: No
BIP103: No

When should we initiate the hardfork?
BIP100: 2016-01-11#
BIP101: 2 weeks after 75% miner support, but not before 2016-01-11
BIP102: 2015-11-11
BIP103: 2017-01-01

# The network does not actually fork until having 90% miner support

What should be the block size at initiation?
BIP100: 1MB
BIP101: 8MB*
BIP102: 2MB
BIP103: 1MB

* It depends on the exact time of initiation, e.g. 8MB if initiated on 2016-01-11, 16MB if initiated on 2018-01-10.

Should we allow further increase / decrease?
BIP100: By miner voting, 0.5x - 2x every 12000 blocks (~3 months)
BIP101: Double every 2 years, with linear interpolations in between (41.4% p.a.)
BIP102: No
BIP103: +4.4% every 97 days (double every 4.3 years, or 17.7% p.a.)

The earliest date for a >=2MB block?
BIP100: 2016-04-03^
BIP101: 2016-01-11
BIP102: 2015-11-11
BIP103: 2020-12-27

^ Assuming 10 minutes blocks and votes cast before 2016-01-11 are not counted

What should be the final block size?
BIP100: 32MB is the max, but it is possible to reduce by miner voting
BIP101: 8192MB
BIP102: 2MB
BIP103: 2048MB

When should we have the final block size?
BIP100: Decided by miners
BIP101: 2036-01-06
BIP102: 2015-11-11
BIP103: 2063-07-09

Supporting big block (0.58531338 BTC):

This address 16mT7jrpkjnJBD7a3TM2awyxHub58H6r6Z with 0.58531338 BTC as of 201508162045UTC supports a combination of BIP 100 and BIP 101 where the voting system and upgrading mechanism from BIP 100 is used as a voting system for voting for the next step increase proposed in the block increase scheme in BIP 101. E.g. for each step up increase proposed in BIP 101, the BIP 100 voting is used to determine whether to go ahead with the increase or postpone for a later date.

those pools support bigger blocks but they won't switch to a fork like XT, if i remember correctly they said that once.

This thread is NOT about any specific big block implementation

[LiteCoinGuy]

very valuable thread, thanks. i guess you can add KnC Miners as pro 8 MB.


(the only way for bigger blocks is XT)



edit:

just saw that KnC is already listed.

Also some well known people like Roger Ver and Andreas Antonopoulos support bigger blocks.

[jl2012]

very vaulable thread, thanks. i guess you can add KnC Miners as pro 8 MB.

It is counted already

Just a heads up: chinese pools supports agreed big blocks. That doesn't necessarily mean they support switching to eks tee. http://cointelegraph.com/news/114657/chinese-mining-pools-call-for-consensus-refuse-switch-to-bitcoin-xt

Thanks for this thread, @OP!

[jl2012]

Big block supporting client has become the top 5 user agent in the Bitcoin network

[LiteCoinGuy]

and it is only 2 days old. there is a reason why the software was released MONTHS before we NEED that software. because some clever folks have the ability to predict what will happen in the future and it is good to be prepared.
