1  Bitcoin / Development & Technical Discussion / Re: Data history for mined blocks on: September 10, 2018, 03:43:43 PM
I eventually used the JSON data from api.smartbit.com.au, saved me a lot of time of putting the data together myself.

Thank you all for your inputs!

You can try https://bitcoinstrings.com/, but it's totally converted to text and the blocks' data aren't displayed.
OP_return data were translated too, just ignore them or highlight all the "Mined by" lines then search from other source about which blocks are included in that particular blkXXXXX.dat number.
Sort it out, and you might find what you need.

However, the site's updates were not that frequent (about daily to four times a week)

Thanks, however I would need to devote time to convert text to usable data...


sorry, that was my bad. i always make the same mistake with pages in API calls. Roll Eyes
basically you make the first call:
https://api.smartbit.com.au/v1/blockchain/pool/AntPool?limit=20&sort=height (used 20 so it opens up fast)
then you look for this key in the JSON:
[pool][block_paging][next_link]
which contains the link to next page:
https://api.smartbit.com.au/v1/blockchain/pool/AntPool?next=NTQwMjA2&limit=20

in case you are wondering what the heck "NTQwMjA2" is, it is base64 encoding of the last block height in previous page. in this case the block at index 19 of the array result of the first call which is "540206"

Great thanks! Looks like I will have to find a way to "glue" all these JSONs into a big one..

Still however it looks like https://api.smartbit.com.au/v1/blockchain/pool/AntPool?limit=1000&sort=height&next=1
and
https://api.smartbit.com.au/v1/blockchain/pool/AntPool?limit=1000&sort=height&next=2
return the same data..
4  Bitcoin / Development & Technical Discussion / Re: Data history for mined blocks on: September 07, 2018, 05:00:15 AM
Hmm, yes that looks like a much more useful API.
I tried something like this
https://api.smartbit.com.au/v1/blockchain/pool/AntPool?sort=height&limit=1000
and it gives me up to July 20.
However if I set a limit higher than 1000 then it only returns 10 blocks...
Thanks for helping btw!

I substitute pool_name with a pool but it doesn't work..

you should replace $pool_name with the name:
eg: https://blockchain.info/blocks/AntPool?format=json



Thanks a lot.
Still however this is not enough data, I tried to manually enter the timespan as follows:
https://blockchain.info/blocks/AntPool?format=json&timespan=10days
But if I enter a larger than 10 days timespan, it doesn't return the data (must be a blockchain.info limitation)
Any ideas where I can find such data?
6  Bitcoin / Development & Technical Discussion / Re: Data history for mined blocks on: September 07, 2018, 04:07:44 AM
Upd:
I was looking at blockchain.info API
https://www.blockchain.com/en/api/blockchain_api
and in particular to the bottom: Blocks for specific pool: https://blockchain.info/blocks/$pool_name?format=json
I substitute pool_name with a pool but it doesn't work..
7  Bitcoin / Development & Technical Discussion / Data history for mined blocks on: September 07, 2018, 02:46:10 AM
Hello
I am looking for historic data for mining pools to perform a study.
e.g. for Antpool, how many blocks it mined in January 2018, and for each block what was the Bitcoin network hashrate and what was the pool's hashrate.
I would also like to export them in readable format e.g. JSON.
I only found this in btc.com
https://btc.com/stats/pool/AntPool
which the data is not exportable (you have to click the button on the bottom a million times)
Blockchain.info only has history for 4 days..
Any suggestions?
Thanks!

17  Bitcoin / Bitcoin Technical Support / Re: Time locked transactions on: May 31, 2018, 03:08:11 AM
Ok let me make my question more specific:
Suppose I create a transaction with OP_CHECKLOCKTIMEVERIFY set into some block in the future. I understand that this transaction is invalid until we reach that block.
My question was after I create and sign this transaction, what do I do with it? Of course it cannot be mined since it is invalid. Heisenberg_Hunter said I can only store it in a safe place, maybe sending it to the recipient letting him know that I have this transaction ready to broadcast it as soon as I can. But is it somewhere documented that it cannot be broadcasted by bitcoin nodes?
18  Bitcoin / Bitcoin Technical Support / Time locked transactions on: May 30, 2018, 05:01:50 PM
I'm looking for information on time-locked transactions for bitcoin. How is this transaction created exactly? Does this transaction remain off-chain between the sender and the receiver until the time has elapsed? Does this transaction remain on the mempool until that time?
