Bitcoin cash p2pkh

And if the answer is yes, which I so hope, what will the prefixes be? Right now all Bitcoin Core prefixes start with 1 or 3. EDIT: P2PKH addresses will start with "q".

BitPay recently launched a public beta for Bitcoin Cash support in our Copay bitcoin wallet. We will follow these conventions in all of our software that supports the Bitcoin Cash block chain.

Bitcoin wallet address example

Like Bitcoin, Bitcoin Cash supports pay to public key hash p2pkh and pay to script hash p2sh addresses. These addresses include a version byte. A naive way to accept bitcoin as a merchant is to tell your customers to send money to a single invoice address.

However this does not work because Bitcoin transactions are public on the block chain , so if a customer Alice sends you bitcoins then a malicious agent Bob could see that same transaction and send you an email claiming that he paid. You would have no way of knowing whether it was Alice or Bob who send coins to your invoice.

This is why each customer must be given a brand new invoice. Creating invoices can be done without an Internet connection and does not require any contact or registration with the Bitcoin network.

Welcome to Reddit,

It is possible to create large batches of invoices offline using freely available software tools. Generating batches of invoices is useful in several scenarios, such as e-commerce websites where a unique pre-generated invoice address is dispensed to each customer who chooses a "pay with Bitcoin" option.

Newer "HD wallets" can generate a "master public key" token which can be used to allow untrusted systems such as webservers to generate an unlimited number of invoices without the ability to spend the bitcoins received. Old-style Bitcoin invoice addresses are case-sensitive. Bitcoin invoices should be copied and pasted using the computer's clipboard wherever possible. If you hand-key a Bitcoin invoice address, and each character is not transcribed exactly - including capitalization - the incorrect invoice address will most likely be rejected by the Bitcoin software.

You will have to check your entry and try again.

Invoice address

The probability that a mistyped invoice is accepted as being valid is 1 in 2 32 , that is, approximately 1 in 4. Most Bitcoin wallets have a function to "sign" a message, proving the entity receiving funds with an invoice has agreed to the message. This can be used to, for example, finalise a contract in a cryptographically provable way prior to making payment for it.

Some services will also piggy-back on this capability by dedicating a specific invoice address for authentication only, in which case the invoice address should never be used for actual Bitcoin transactions. When you login to or use their service, you will provide a signature proving you are the same person with the pre-negotiated invoice address. It is important to note that these signatures only prove one receives with an invoice. Since Bitcoin transactions do not have a "from" address, you cannot prove you are the sender of funds.

Current standards for message signatures are only compatible with "version zero" bitcoin invoice addresses that begin with the number 1. If you would like to validate a Bitcoin invoice address in an application, it is advisable to use a method from this thread rather than to just check for string length, allowed characters, or that the invoice starts with a 1 or 3.

I love it! I so hope Bitpay switches to it! How does this relate with the 1 and 3 in Bitcoin Core or does it not? I thought 1 was normal and 3 was multi-sig. Is that wrong? Abtc address that starts with 3 is a segwit wallet, right? Can Electrum 1.
