Is P2SH-wrapped P2PKH possible? There is a known form of address that called P2SH-wrapped P2PKH, wrapping SegWit address as Base58 (P2SH) address. Thinking about such address type, I come up with the question: Is P2SH-wrapped P2PKH possible? I know that it is completely useless and meaningless, but I want to think about it now. Step 1: Decide an address to convert Let's use the address 1CciesT23BNionJeXrbxmjc7ywfiyM4oLW as it is used as a sample here . Step 2: Convert it into "output script", then hash it using "hash160" I got OP_DUP OP_HASH160 7f6ab65fa911f558ca2dde3e9d073acb02c0d5c6 OP_EQUALVERIFY OP_CHECKSIG. Hashed result is c852ac34a1c76b63a279c97502c9ccc4e3cb9e8b. Step 3: Make P2SH address from hashed script toBase58Check(c852ac34a1c76b63a279c97502c9ccc4e3cb9e8b, 5) = 3KxE77EHe1ip6WGRifwr9fZ5WBDGsLyWFz The result 3KxE77EHe1ip6WGRifwr9fZ5WBDGsLyWFz is what I want. Here is the code to reproduce this address generation. Question Is that possible to ...

How to import p2wsh-in-p2sh multisig as watch-only? I've created a p2wsh-in-p2sh multisig address using an offline node. I have the address and redeem script, as provided by bitcoin-cli addmultisigaddress on the offline node. How do I import this as a watch-only address on an online node, so I can use the online node to create transactions ? I have tried the following: $ bitcoin-cli -testnet -rpcwallet=glacier importmulti '[{ "scriptPubKey": { "address": "2MzqiaZzpLT2SSBfsFqqo3FpZsP8g6WTvyC" }, "timestamp":"now", "redeemscript":"5221029f531503facdac2496f50a446d9bd29846a06a04a45e3845b656bb471df422fc2102e30787703a990e4015a2cb9071fcfd1c7d4641fb294e4b4c3f5f6b450a1925132102da28088a8022651171c4f13429b98709dabe13bc6da526537fdd2d0730dd2dbb2103286c96ecaa850a6ba43cc45fbb539c1fb1d65c23cc0f3cd09fcf9765826ff9de54ae", "watchonly":true, "label":"Glacier 2012-12-21" }]' [ { "su...

Sent BTC to Jaxx Wallet Never Received A friend suggested I use Jaxx Wallet so I downloaded the software and sent my BTC using their QR Code from Coinbase. Looking back, I should've left it where it was! It never arrived. I also sent LTC using the same QR Code method. That has arrived and is in my Jaxx Wallet now. I see my transaction completed and verified on the blockchain. How do I locate where it is? How can I trace that this transaction was actually sent (and maybe received) by Jaxx although it doesn't show in my wallet? http://bit.ly/2EE6PDt

What rules does the Exodus Wallet follow in selecting outputs to cover the amount being sent? If you use CTRL-Shift-D to open the Developer Menu in the Exodus wallet, you can go under Developer|Assets and select your crypto and then choose the "Export Address" function. This saves a csv file for you that lists the internal "HD" addresses for which you have private keys. If you've done a few transactions, receiving and sending, you'll have a few of these addresses that still have some amount in them. When you tell Exodus that you want to send some of that crypto to another address, it will follow a strategy of selecting those addresses in some kind of order in order to get a total which is greater than the sending amount. I'm trying to find out in what order the Exodus wallet will choose those addresses. http://bit.ly/2CtPJq8

How to calculate profit for merged mining coins I am making a mining profitability calculator for these coins that use merged mining: BlakeCoin However I dont know on how I would actually calculate the profitability for that. I made a calculator for Sia, SiaPrime, SiaClassic, and Hyperspace(these dont use merged mining): BlakeMining.com The way I calculated the profit for that was by doing (hashrate/(difficulty/BlockTime)) * ((300000 - height - ((period/BlockTime)/2)) * (period/BlockTime)) (Using JavaScript) and that gave an accurate result. I was thinking that maybe I could do the same thing but then divide the result by the number of coins on the merged mining network. I dont know if that will give accurate results though. If you know how to calculate this or if there is some article/answered question on this, please send a link. -Thanks! http://bit.ly/2BzRBfD

What are the issues of running lightning daemon with pruning node? Most lightning implementations I came across don't officially support pruned full node. Why is pruned mode implementation a challenge? What risk am I taking when I run lnd with pruned bitcoind? http://bit.ly/2QMHtuq

Determining the byte size of multisig transaction beforehand knowing the details of the transaction If I know the m of n values of the multisig, the # of inputs (all of which are from the multisig and require m signatures) and outputs and the redeem script, how can I determine the size of the transaction after m signatures? http://bit.ly/2CtfUgL
