1  Bitcoin / Pools / Bitcoin testnet Solo mining - RPC to Stratum. How? on: April 14, 2024, 07:07:30 AM
Once upon a time, I mined a bitcoin testnet on an ASIC that is now 10 years old (Prospero X-1).
Now I wanted to go back to it and found that it doesn't work. I've spent many hours on this and I'm getting lost.

Mining via long polling, getblocktemplate... Doesn't work anymore, stratum is needed. But Slush0/stratum is also no longer developed, same as bfgminer (stratum-proxy)... I also tried P2Pool... I think getblocktemplate has changed and the older SW doesn't work anymore.

So, could someone direct me to a solution how to use Bitcoin core v26.1 and more for mining via the stratum protocol?

I want to have everything set up and ready for a possible transition to testnet4, since I have been running a testnet faucet for 10 years and I would hate to have to close it.
2  Bitcoin / Development & Technical Discussion / Add nodes from blockchain.info to bitcoind on: February 09, 2015, 01:51:42 PM
Hello,

I've created a simple bash script for insert nodes from blockchain.info to bitcoind.

Code:
#!/bin/bash
 
# Add nodes from blockchain.info to bitcoind
# Tested on bitcoin version 0.9.1
 
#run as Bitcoin user
#su -l Bitcoin -c "/home/addnode.sh" -s /bin/sh
 
clear
 
IFS=$'\n'
nodes=`curl -s http://blockchain.info/connected-nodes | egrep -o '([[:digit:]]+\.[[:digit:]]+\.[[:digit:]]+\.[[:digit:]]+)' | sort -u`
i=0
for node in $nodes; do
bitcoin=`bitcoind addnode $node add 2>&1`
if [ -z "$bitcoin" ]; then
((i++))
elif [ -n "`echo $bitcoin | grep -v 'error: {"code":-23,"message":"Error: Node already added"}'`" ]; then
echo "Unknown error: $bitcoin"
exit 1
fi
done
 
if [ "$i" -gt 0 ]; then
echo "Successfully added $i new nodes."
else
echo "There are no new nodes."
fi

Can be run from a cronjob (change path):
Code:
*/30 * * * * /home/addnode.sh > /dev/null

3  Economy / Micro Earnings / Bitcoin, Groestlcoin testnet faucet (coinfaucet.eu) on: February 09, 2015, 12:51:14 PM
Hi there,

This faucet was launched in 2014, the first transaction took place on 2014-12-22 08:15:36.

Supported coins are Bitcoin testnet, Groestlcoin testnet
Bitcoin testnet - https://coinfaucet.eu/btc-testnet/
Groestlcoin testnet - https://coinfaucet.eu/grs-testnet/



Faucet supports addresses.

Example testnet BTC (Legacy/Segwit/Taproot):
mwZPfTMiVQEzXTEhwLmi5dcmq7EvcDqLGr
tb1q0g5y6yhk7z25n7zxl4vtcanxyp44ng74x8esta
tb1parlan9xte2slkmj0j8u6wzdnzye55n4ljrlzrxp8ujqx2fmzcu7q4cakc5

Example testnet GRS (Legacy/Segwit):
2Mxgq2A3hWuDWC1TwLTxJRmWm5ck8Vwzbr8
tgrs1q408nujxypq6c5lt3nghvpsqvdey9utwlwpfkcd



Please do not ask me to send a coin outside the faucet!
My stocks of coins are shrinking and I don't generate new ones anymore.

If you really need a lot of testing coins, try some other solution. For example:
bitcoin-testnet-box
bitcoin-regnet

Or you can swap them for another coin, for example here:
altquick.com/swap
