#1 Bitcoin Halving 2024 Countdown & Date ETA (BTC Clock)

How to trustlessly verify current status of Segwit

Bitcoin is a trustless system. The motto is "Don't trust, verify!". In this spirit I wanted to be able to tell how many blocks among last 2016 are signalling Segwit support. So I wrote a simple bash script:
#!/bin/bash YES=0; NO=0 for i in $(seq $[$(bitcoin-cli getblockcount)-2015] $(bitcoin-cli getblockcount)); do bitcoin-cli getblock $(bitcoin-cli getblockhash $i)| grep '"version"' | sed -e 's/^.*: /obase=2;/' -e 's/,$//' | bc | grep -q '1.$' && YES=$[$YES+1] || NO=$[$NO+1] done echo "Supporting: $YES, opposing: $NO" 
You can run it on your full node to calculate current status. It takes some time, so be patient. Example output from my node:
Supporting: 11, opposing: 2005 
(As somebody already mentioned, Slushpool started to signal prematurely.)
The script just asks bitcoind how many blocks there are, then asks hash of each block with number from (inclusive range) and for each hash it asks for block, to get version. Version is converted to binary and then appropriate bit is grepped and counted.
If you ever see Supporting: 1916 (or more) at the end of retarget period, you know Segwit locked-in. It should even work on older clients, so you can activate manually. :)
Enjoy!
Update: as Totont01 pointed out, you have to count within retarget period.

Help with a project importing data from another site

I'm trying to import the data for various currencies under the "available supply" section on coinmarketcap.com and display it on my own sites page (and have continuously update/fetch the latest data, as its constantly updating there).
What is the easiest way to do this?
Someone helped me previously doing it with bitcoin. This is the code he used:
var btcRequest = new XMLHttpRequest();
btcRequest.open('get', 'https://blockchain.info/q/getblockcount?cors=true');
btcRequest.onload = function() {
if (btcRequest.readyState !== 4) return;
However, I want to do this for other currencies there too, such as Dash, Dogecoin and Peercoin. How do I fetch the data from these sites? (which list the total number of coins, or blocks which can be used to calculate the # of coins): Dash here https://chainz.cryptoid.info/dash/ Dogecoin here http://dogechain.info/chain/Dogecoin Peercoin here: http://ppc.blockr.io/
Alternatively, can I just pull the data from under "available supply" from coinmarketcap.com directly? I dont know if its easier to get it from the sites above or from coinmarketcap.com, please advise which is the easiest way to do this as I do not know (please be as specific and detailed as possible if you would as I am a newbie).
Thanks in advance!
