Oh, by the way, the same procedure as last year, Miss Sophie?
Same procedure as every year, James.

ACK fa0c1b5820d12354d1e31bb561e73165b0adfbac - mainnet, testnet and signet output matches my node.

mainnet blocks & chainstate size:

du -sh /Users/michael/Library/Application\ Support/Bitcoin/blocks
325G	/Users/michael/Library/Application Support/Bitcoin/blocks
du -sh /Users/michael/Library/Application\ Support/Bitcoin/chainstate 
3.9G	/Users/michael/Library/Application Support/Bitcoin/chainstate

6 seems a bit aggressive (my chainstate is 3.9), but it doesn't matter that much, as this is only used for the intro dialog.

Mine is almost 5 🤷‍♂️

$ du -sh ./chainstate/ 4.8G ./chainstate/

Mine is 4, fwiw.

3.9 here like @fanquake

Having 4.0G here for chainstate.

$ du -sh .bitcoin/chainstate/
4.0G .bitcoin/chainstate/

Mine is 5.2G

ACK fa0c1b5820d12354d1e31bb561e73165b0adfbac mainnet and testnet params.

jonatack

On mainnet, I see a blockchain size of 326.2 and a chainstate size of 3.9.

The chaintxdata for me are the same as this PR, except for signet.

jonatack · 2020-11-01T09:48:19Z

src/chainparams.cpp

Mainnet chaintxdata seem good:

$ ./src/bitcoin-cli getchaintxstats 4096 0000000000000000000b9d2ec5a352ecba0592946514a92f14319dc2b367fc72 { "time": 1603995752, "txcount": 582083445, "window_final_block_hash": "0000000000000000000b9d2ec5a352ecba0592946514a92f14319dc2b367fc72", "window_final_block_height": 654683, "window_block_count": 4096, "window_tx_count": 8995148, "window_interval": 2563468, "txrate": 3.508976121410527 }

Testnet3 chaintxdata seem good:

$ ./src/bitcoin-cli -testnet getchaintxstats 4096 000000000000006433d1efec504c53ca332b64963c425395515b01977bd7b3b0 { "time": 1603359686, "txcount": 58090238, "window_final_block_hash": "000000000000006433d1efec504c53ca332b64963c425395515b01977bd7b3b0", "window_final_block_height": 1864000, "window_block_count": 4096, "window_tx_count": 143148, "window_interval": 1161080, "txrate": 0.1232886622799463 }

jonatack · 2020-11-01T09:53:15Z

src/chainparams.cpp

I have different Signet chaintxdata:

$ ./src/bitcoin-cli -signet getchaintxstats 4096 00000128807d9175c494e24d805fc7854f7d79aa965cbb128342ad8b70cecfa5 { "time": 1601382000, "txcount": 5435, "window_final_block_hash": "00000128807d9175c494e24d805fc7854f7d79aa965cbb128342ad8b70cecfa5", "window_final_block_height": 5348, "window_block_count": 4096, "window_tx_count": 4182, "window_interval": 2202970, "txrate": 0.001898346323372538 }

(and so different getblockheader data as well)

$ ./src/bitcoin-cli -signet getblockheader "00000128807d9175c494e24d805fc7854f7d79aa965cbb128342ad8b70cecfa5" { "hash": "00000128807d9175c494e24d805fc7854f7d79aa965cbb128342ad8b70cecfa5", "height": 5348, "chainwork": "0000000000000000000000000000000000000000000000000000000d145533ce", }

The comment has not been updated https://github.com/bitcoin/bitcoin/pull/20263/files#r515620099 . Nice find.

ACK for mainnet and testnet, not sure why I have different data for signet.

jonatack · 2020-11-01T11:18:25Z

src/chainparams.cpp

The mainnet nMinimumChainWork and defaultAssumeValid consensus params match up for me

$ ./src/bitcoin-cli getblockheader 0000000000000000000b9d2ec5a352ecba0592946514a92f14319dc2b367fc72 { "hash": "0000000000000000000b9d2ec5a352ecba0592946514a92f14319dc2b367fc72", "height": 654683, "chainwork": "00000000000000000000000000000000000000001533efd8d716a517fe2c5008", }

Verified mainnet, testnet3, signet params via the following commands (starting with block height as first input feels most natural to me):

$ bitcoin-cli getblockheader $(bitcoin-cli getblockhash 654683) | grep "\"chainwork\|\"hash"
$ bitcoin-cli getchaintxstats 4096 0000000000000000000b9d2ec5a352ecba0592946514a92f14319dc2b367fc72

$ bitcoin-cli -testnet getblockheader $(bitcoin-cli -testnet getblockhash 1864000) | grep "\"chainwork\|\"hash"
$ bitcoin-cli -testnet getchaintxstats 4096 000000000000006433d1efec504c53ca332b64963c425395515b01977bd7b3b0

$ bitcoin-cli -signet getblockheader $(bitcoin-cli -signet getblockhash 9434) | grep "\"chainwork\|\"hash"
$ bitcoin-cli -signet getchaintxstats 4096 0000002a1de0f46379358c1fd09906f7ac59adf3712323ed90eb59e4c183c020

ACK (modulo the getchaintxstats signet comment that has not been updated yet (#20263 (comment)).

maflcko · 2020-11-02T09:15:34Z

I force pushed to fixup the signet comment. Should be easy to re-ACK for those that already ACKed

ACK fa90ba3 - mainnet and testnet data matches my node.
