What would be the process for identifying a person that performed a transaction from a wallet on a personal device?


The block chain doesn't report the IP address and the IP address isn't passes by nodes. Any entities knowledge of Bitcoin network is limited to the connections it has. If you get a transaction from a specific IP address you can't know that IP address originated the transaction you simply know it came from that IP address. It was either originated or relayed by that node.

The more connections you have to the network the more information you would have about where an transaction originated. However no matter how many connections you have you can never know you have a connection to every single node, thus all you can know when you see a specific transaction is that node at IP address X is where the transaction was first seen.

You can never be 100% sure of the originating node as you can never be 100% sure you have connections to ever node in the network.

Someone concerned about privacy could restrict the nodes they send transactions to only nodes they trust. This...

Bitcoin is just another currency. Bitcoin refers to the entire currency system and BitCOINS are basic units (just like Dollar or Pound)

Like other currencies, you can save/ spend Bitcoins, or exchange with other currencies.

What is Digital currency?

Digital currency can be easily stored and used on a computer.

Dollar can be considered digital currency as such, we can use it to shop online.

However, dollar supply is controlled by a centralized bank.

What is Decentralized?

Gold coins are decentralized, means, there is no central authority controls the supply of gold.

Anyone can dig for gold and distribute gold, but it is not easy to exchange with exact change.

Also not possible to transfer over internet.

Bitcoin is the world’s first currency that is both Digital and Decentralized, somewhat like digital gold.

Bitcoins is a stateless currency, not associated with any nation,...

The digital wallet trend appears to be unstoppable. According to a recent report by the Hong Kong Monetary Authority, the number of P2P payments in Hong Kong has grown rapidly, hitting a record HK$537 million in total transactions in the fourth quarter of 2016. In fact, the report reveals that the total number of stored value facilities (SVF) accounts in use in Hong Kong has reached nearly 40.5 million. Or, to put it another way, Hongkongers already have an average of 5.5 e-wallets each.

And Hong Kong isn’t an exception. With more banks and payment service providers promoting digital payments across the region, the pressure is on for the technology industry to respond and deliver on the promises of secure and convenient payments.

The key to e-cash to success

There’s clearly every reason to think that digital wallets will soon be as ubiquitous as the mobile devices they live on. But for Hong Kong, or any other city, a future based on digital wallets depends on...

All Bitcoin transactions are stored in a public ledger called the blockchain. The data stored in each of these transactions includes a bitcoin payment amount and the Bitcoin addresses of the sender and the recipient (among other things). Because every transaction uses the bitcoins from a prior transaction, and the blockchain is public data, every Bitcoin payment has a traceable history that can be viewed by anyone.

Bitcoin addresses are not themselves linked to a person or entity. That’s why Bitcoin is often called pseudonymous or pseudo-anonymous. However, a person’s identity can be associated with a Bitcoin address through other means. Once that occurs, it’s possible to determine that person’s transactions backward and forward through the blockchain history. A single anonymity breach can uncover an individual’s entire Bitcoin transaction history.

But how is an address linked with a person? Most commonly, the association occurs when people publish their name together...

What is Bitcoin?

Bitcoin is a consensus network that enables a new payment system and a completely digital money. It is the first decentralized peer-to-peer payment network that is powered by its users with no central authority or middlemen. From a user perspective, Bitcoin is pretty much like cash for the Internet. Bitcoin can also be seen as the most prominent triple entry bookkeeping system in existence.

Bitcoin is the first implementation of a concept called crypto-currency", which was first described in 1998 by Wei Dai on the cypherpunks mailing list, suggesting the idea of a new form of money that uses cryptography to control its creation and transactions, rather than a...

Transaction processing relates to any real-time business transaction or process performed by a transaction processing system (TPS) or other business information system (BIS). The process occurs when a user requests completion or fulfillment of any process. Once a a TPS or related system receives a request, it coordinates with the respective system for authorization, data requests or any specific task essential to a complete transaction.

For example, when a cash withdrawal request is made at an ATM machine, the machine first authorizes the user credentials and balance inquiry/status from the back end banking systems. Once the information is received, the ATM machine processes the user request or overall transaction. Moreover, a TPS can accept, reject or halt a transaction based on environmental...

"Transaction denied" means the bank computer said "no" to whatever you asked for. There is no implied reason, but insufficient funds (in your bank account) is one of the more

…common ones. It may also mean that the ATM is, for whatever reason, having problems connecting to your bank's central computers right now. Or it could potentially mean that you're trying to do something the bank doesn't allow as a matter of policy... for example, you may be over your withdrawal limit for the day. Basically, it means "That's not going to be happening." For a detailed explanation of why, you will probably need to contact your bank and/or the operator of the particular ATM you were trying to use....

Basic Information on OFAC and Sanctions

1. What is OFAC and what does it do?

The Office of Foreign Assets Control administers and enforces economic sanctions programs primarily against countries and groups of individuals, such as terrorists and narcotics traffickers. The sanctions can be either comprehensive or selective, using the blocking of assets and trade restrictions to accomplish foreign policy and national security goals. [09-10-02]

2. How long has OFAC been around?

The Treasury Department has a long history of dealing with sanctions. Dating back prior to the War of 1812, Secretary of the Treasury Gallatin administered sanctions imposed against Great Britain for the harassment of American sailors. During the Civil War, Congress approved a law which prohibited transactions with the Confederacy, called for the forfeiture of goods involved in such transactions, and provided a licensing regime under rules and...

Congratulations to Peter Todd - it looks like you've achieved consensus! Everyone is against you on RBF!

Replace By Fee - A Counter-Argument, by Mike Hearn


Repeating past statements, it is acknowledged that Peter’s scorched earth replace-by-fee proposal is aptly named, and would be widely anti-social on the current network.

— Jeff Garzik

Coinbase fully agrees with Mike Hearn. RBF is irrational and harmful to Bitcoin.

— Charlie Lee, engineering manager at Coinbase

Replace-by-fee is a bad idea.

— Gavin Andresen

I agree with Mike & Jeff. Blowing up 0-confirm transactions is vandalism.

— Adam Back (a founder of Blockstream)

Serious question:

Why is Peter Todd allowed to merge bizarre dangerous crap like this, which nobody even asked for and which totally goes against the foundations of Bitcoin (ie, it would ENCOURAGE DOUBLE SPENDS...

ABA Routing Number

This is a nine digit number that appears on all checks along with the bank account number. ABA actually stands for American Banker’s Association. It is also sometimes called the Transit Routing Number. The ABA number identifies which banks the account is from. Each bank is issues its own ABA number. When you send a bank wire or an ACH transaction from one bank to another, you need both the ABA number and the bank account number.

ACH/Automated Clearing House

ACH is short for Automated Clearing House. When you send and receive money from one bank account to another, you can do it through bank wire, which happens very quickly the same day, or ACH, which takes a couple days. Think of ACH as an electronic payment from one bank account...

Transaction processing is a style of computing that divides work into individual, indivisible operations, called transactions.[1] A transaction processing system (TPS) or transaction server is a software system, or software/hardware combination, that supports transaction processing .


The first transaction processing system was SABRE, made by IBM for American Airlines, which became operational in 1970. Designed to process up to 83,000 transactions a day, the system ran on two IBM 7090 computers. SABRE was migrated to IBM System/360 computers in 1972, and became an IBM product first as Airline control Program (ACP) and later as Transaction Processing Facility (TPF). In addition to airlines TPF is used by large banks, credit card companies, and hotel chains.

The Hewlett-Packard NonStop system (formerly Tandem NonStop) was a hardware and software system designed for Online Transaction Processing (OLTP) introduced in 1976. The systems were designed...

What are BPMN and BPD?

BPMN provides business analysts with a set of graphical notations for modeling business processes. It was initially developed by the Business Process Management Initiative (BPMI) and is now being maintained by the Object Management Group (OMG). One of the motivations of developing BPMN is to provide a common graphical language for people in different roles, from different countries, and/or with different spoken languages to understand the same business process without barrier.

BPD, short for Business Process Diagram, is where business process is modeled, using BPMN. It is a...

Payment Application Data Security Standards (PA-DSS) – PA-DSS is the global security standard created by the Payment Card Industry Security Standards Council (PCI SSC). PA-DSS is meant to provide the definitive data standard for software vendors that develop payment applications. The standard aims to prevent developed payment applications for third parties from storing prohibited secure data, including magnetic stripe, cardholder verification value (CVV2), or PIN. Also see Payment Card Industry Security Standards Council (PCI SSC).

Payment Application Qualified Security Assessor (PA-QSA) – A PA-QSA is a company that is qualified by the Payment Card Industry Security Standards Council (PCI SSC) to assess organizational compliance to the PCI PA-DSS.

Payment Card Industry Audits (PCI Audits) – PCI requires any system that stores, processes, or transmits cardholder data to be subject to annual reviews to verify compliance with the PCI Data Security Standard (PCI...
