3 Digital Revolution The digital revolution that started decades ago is still disrupting existing systems and structures. The Internet of information which represent the 1st generation of the digital revolution has disrupted institutions like printing press, post office, library and commutations. Now another round of digital revolution is here to give us the internet of value that will change world of Finance and the global economy.

4 Digital & Knowledge Economy Digital economy refers to an economy that is based on digital computing technologies. The digital economy is also sometimes called the Internet Economy, the New Economy, or Web Economy- The knowledge economy addresses how education and knowledge generally called "human capital can serve as a productive asset or a business product since innovative and intellectual services and products can be sold and exported and can yield profits for the individual, the business and the economy - Investopedia

5 Bitcoin is a Peer-to-Peer electronic cash system What is Bitcoin A form of digital currency in which encryption techniques are used to regulate the generation of units of currency and verify the transfer of funds, operating in a peer to peer network independently of a central bank. Bitcoin is popularly referred to as the money of the internet The first Bitcoin specification and proof of concept was published in 2009 in a cryptography mailing list by Satoshi Nakamoto. Satoshi left the project in late 2010 without revealing much about himself. The community has since grown exponentially with many developers working on Bitcoin.

6 Terms Wallet Mining Private Key Address Exchange Description Bitcoin Terminology A Bitcoin wallet is loosely the equivalent of a physical wallet on the Bitcoin network. The wallet actually contains your private key(s) which allow you to spend the bitcoins allocated to it in the block chain. Each Bitcoin wallet can show you the total balance of all bitcoins it controls and lets you pay a specific amount to a specific person, just like a real wallet. This is different to credit cards where you are charged by the merchant. Bitcoin mining is the process of making computer hardware do mathematical calculations for the Bitcoin network to confirm transactions and increase security. As a reward for their services, Bitcoin miners can collect transaction fees for the transactions they confirm, along with newly created bitcoins. Mining is a specialized and competitive market where the rewards are divided up according to how much calculation is done. Not all Bitcoin users do Bitcoin mining, and it is not an easy way to make money. A private key is a string of data that shows you have access to bitcoins in a specific wallet. Think of a private key like a password; private keys must never be revealed to anyone but you, as they allow you to spend the bitcoins from your bitcoin wallet through a cryptographic signature. Addresses (Cryptocurrency addresses) are used to receive and send transactions on the network. An address is a string of alphanumeric characters, but can also be represented as a scannable QR code. An exchange is a service which allows people to buy and sell bitcoins to each other. The most popular at the time of this writing are MtGox, CryptoXChange, Cavirtex (Bitcoin to Canadian dollars) and Intersango (Bitcoin to UK pounds).

8 How Bitcoin Transactions are Processed

9 BLOCHKCHAIN Blockchain is an Emerging technologies that is promising Trustless Trust and Real Time Audit Effect Blockchain is a protocol for building an immutable historical record of transactions. It represent both an innovation and trust engine A platform for building diverse innovative applications A Triple Entry Ledger that powers Bitcoin and other cryptocurrencies Blockchain uses a combination of decentralization, incentive mechanism, consensus algorithm, encryption and cryptographic signatures to provide security and trust assurance

10 Triple Entry Ledger This brings together financial cryptography innovations such as the Signed Receipt with the standard accountancy techniques of double entry bookkeeping. So you have three entries: the credit, the debit and the receipt (the cryptographic signed acknowledgement of the transaction verified by the crowd.)

11 BLOCKCHAIN A blockchain is simply a specific type of database (or ledger) that stores transactions with the following properties Transactions are stored in a string of digital blocks, with each block referencing the prior one. A block of transactions is only added to the chain if it is verified by cryptographic techniques using significant computing power. Crucially, the nature of the verification process is such that the validity of any block can be verified easily and quickly, effectively eliminating the possibility of fraudulent transactions and making it virtually impossible to retroactively alter any single block of the chain The database is distributed, i.e. all users are notified immediately of new additions to the blockchain. The distributed nature of the blockchain allows for all users to have a verified and secure version of the blockchain at all times.

13 Blockchain Attributes Decentralization Tamper-proof and immutable records Attack resistance Real Time Audit Effect

14 Applications of Blockchain

15 BENEFITS OF BLOCKCHAIN Lower cost of transaction Faster speed of transaction Enable micro payment Improved security Reduced counter-party risk Inflation control Immutable and tamper-proof record Open and Transparent Provides Real Time Audit Effect Innovation & Trust Engine Can discourage corruption Reduce Security Breaches Provides real time visibility of transaction Promotes economy of transparency Can Prevent or reduce future occurrence of financial crisis

16 Drawbacks of Blockchain Adoption New and evolving Low level of awareness Technical complexity Regulatory Uncertainty Abuse of bitcoin By Criminals e.g. Ransomware Scalability Limitations No KYC/AML

20 Bitcoin in Nigeria No legal framework exist to regulate use of bitcoin in Nigeria. The CBN has expressed concern on the possible use of the cryptocurrency for money laundary Cryptocurrency is a new area for AML agents to cover NAIRA/BITCOIN EXCHANGES g/account/login/ ex.php Voguepay.com Bitstake.co Instantgold.com

21 Some Statistics in Bitcoin space 1 BTC is being exchanged for about N320, 000 Naira as at 17 October, The smallest unit of bitcoin is Satoshi There are 100 million of them in one Bitcoin. Bitcioin transactions are public and can be viewed online at

22 The Good, The Bad and The Ugly BITCOIN REAL LIFE SCENERIOS

23 The Good - Isle of Man Case Study e-commerce sector, including online gaming, accounts for more than 20% of the Isle of Man s annual gross domestic product. The Isle government hopes that digital currency may come to a new industry that will eventually account for a big part of the protectorate domestic income. The government is seeking to make the island one of the most important hubs for Bitcoin. There are currently about 25 startups working with digital currencies or the blockchain technology, and that number is growing steadily. Nick Williamson, an American entrepreneur who decided to settle in the Isle, launched a startup called Pythia. The startup provides off-the-shelf software that allows customers to develop and run their own customized blockchains. To further develop and test his product, he signed a partnership with the Isle of Man government to help establish a new register of the island s cryptocurrency companies.

24 The Bad: Mtgaux Case Mtgaux was a Japanese company which ended up declaring bankrupt leaving many people loosing their money Mtgaux was once largest bitcoin exchange but became insolvent This is a cautionary tale about the use of exchanges Mtgaux ran a Bitcoin Escrow Service

25 The Ugly: Silk Road Case Silk Road was an online black market, best known as a platform for selling illegal drugs In 2013, the Federal Bureau of Investigation (FBI) shut down the website and arrested Ross William Ulbricht under charges of being the site's pseudonymous founder "Dread Pirate Roberts" Ulbricht was convicted of all seven charges in U.S. Federal Court in Manhattan relating to Silk Road and was sentenced to life in prison. Further charges alleging murder-forhire remain pending in Maryland

26 General Challenges of Digital Economy Innovations They are mostly brought about by new technologies yet to be understood They normally don t fit into the existing policy framework They are new, evolving and unstable with high chance of failure in the earlier stages Mostly promoted by people outside official system thereby creating a form of shadow operation. Prone to abuse for Money laundering Prone to general abuse by criminals Rate of change too fast for policy to catch up with Censorship Resistant Absence of regulatory framework Absence of public protection schemes.

27 Blockchain: Strong Use Cases in Nigeria Land Title Record System with Real Time Audit and Ownership Transfer. Electronic Voting System with trust assurance, tamper-proof record and real time audit effect. Real Time Value Chain Monitor for pharmaceutical products Real Time vehicle inspection mobile application. Crowd sourcing application for Military Intelligence Crowd souring application for Business Intelligence

28 CDIN PARTNERS WITH CFIN TO PIONEER BLOCKCHAIN ALLIANCE IN NIGERIA DIGITAL ECONOMY CDIN/CFIN CYBERSECURITY DIGITAL INVESTIGATION

29 NIGERIA BLOCKCHAIN ALLIANCE: why it matters The Nigeria Blockchain Alliance is a critical step for protecting public safety by combating criminal activity on the blockchain. But it is also a critical step for the growth of the blockchain industry in Nigeria. By addressing misperceptions about Bitcoin, other digital currencies, and the blockchain generally, and by highlighting the industry s good-faith efforts to cooperate with investigations, we can promote an approach to enforcement and regulation that does not stifle innovation.
