What is Bitcoin and the Blockchain?

What is Bitcoin

What is Bitcoin?

Bitcoin is the first decentralised digital currency in the world. It was introduced in 2008 by an anonymous developer named Satoshi Nakamoto.

Bitcoin operates on peer-to-peer technology and does not require any bank or a financial institution as an intermediary. Bitcoin can be used to purchase goods and services online, make cheap international money transfers and it is also considered as one of many innovative new ways to invest your money as its price has been increasing substantially as its adoption is growing globally.

What is the Blockchain?

The blockchain is the underlying technology that the cryptocurrency bitcoin is built on. The blockchain is an immutable open-source distributed ledger network that publicly records all bitcoin transactions. The digital ledger can be viewed at Blockchain.info.

The blockchain is upheld and updated by all network participants who utilize their computing power to maintain and secure the bitcoin network in real-time. Hence, if some participants of the bitcoin network fall victim to an attack, the network remains functional as it is a decentralized peer-to-peer network. The bitcoin blockchain participants also verify and process all transactions on the bitcoin network. For this service, these bitcoin network participants receive new bitcoins through what is referred to as mining.

Furthermore, due to its open-source nature, the code for the blockchain can be changed to create new digital currencies but it can also be augmented so that it can be employed for non-financial uses.

For example, new blockchains could be used for transparent voter registration, to record proof of ownership of assets or land and intellectual property or for digital identity verification. The possibilities for the potential uses of the blockchain are almost limitless. That is also one of the primary reasons why there has been such a hype around bitcoin and the blockchain in the tech space.

Where can you buy bitcoins?

Bitcoin can be bought via digital cryptocurrency exchanges or on a peer-to-peer basis using LocalBitcoins.com.

In Africa, the most popular centralised cryptocurrency exchanges are Ice3X and BitX. However, the majority of bitcoin transactions in Africa occur over the peer-to-peer exchange LocalBitcoins.com.

What can Bitcoin do in Africa?

One of bitcoin’s key selling points is its low transaction fee when conducting money transfers regardless of the location of the sender and the recipient. Hence, the biggest case for bitcoin adoption in Africa is for remittance purposes. However, the use of bitcoin as a spending currency could also be very beneficial to the underbanked communities of Africa that often rely on cash-only transactions.

Mobile Bitcoin WalletThe blockchain, as mentioned above, could be used in all sorts of ways in Africa. Its potential uses range from voter registration to proof of land ownership and even the reduction of corruption. While it will remain to be seen whether the digital currency bitcoin will become a viable everyday spending currency. Its underlying technology, the Blockchain, will without the shadow of a doubt make its impact in Africa for the better of its communities.

Bitcoin Wallet Luno Adds SegWit Support to Lower Transaction Fees

Published

Luno Adds SegWit Support

Luno, one of the most popular bitcoin wallets in Africa, has announced full SegWit integration for bitcoin send and receive transactions. Previously, Luno customers could only receive BTC through a legacy wallet address, which was not integrated with the recent Bitcoin blockchain upgrade SegWit. Only send transactions were SegWit compatible.

With the full integration of SegWit, Luno users can now enjoy cheaper and faster bitcoin transactions.

“By implementing SegWit internally, Luno has managed to reduce the send fees paid by customers by over 25% already. As customers start switching over to new SegWit addresses, this will translate into a further reduction in sending fees in the coming weeks and months,” Werner van Rooyen, head of marketing and communications at Luno stated.

Luno currently operates in South Africa, Nigeria, Malaysia, UK, and in 35 other European countries.

What is SegWit?

Segregated Witness (SegWit) was an upgrade to the Bitcoin blockchain that is intended to address Bitcoin’s scalability challenges as well as fix the issue of transaction malleability. With SegWit, signature data is separated from transaction data in order to enable more transactions to fit into each block. The signature data is kept in an extended block called the witness. As a result, bitcoin transactions become faster and transaction fees become lower.

In theory, the Bitcoin network can handle seven transactions per second. However, in reality, it is around four transactions per second. With the number of bitcoin transactions increasing as bitcoin’s popularity grows, transactions take longer as the unconfirmed transactions pool increases. Therefore, bitcoin users who can afford it have been paying higher transaction fees to incentivise miners to prioritise their transactions and, thereby, increase the speed of their transactions. At the end of 2017, this has led to the average bitcoin transaction fee spiking to over 35 dollars.

However, when SegWit addresses are used, bitcoin transactions become faster and the required resources decrease as well. Consequently, the transaction fees reduce.

How Can You Add a SegWit Wallet Address on Luno?

To add a SegWit address on the Luno wallet you have to follow these steps:

  • Open your Luno account either on the mobile app or the web app
  • Choose “wallets” from the menu
  • Click on your “BTC wallet”
  • Choose “receive bitcoin”
  • Click “add address” and follow the prompt

To receive bitcoin, use your SegWit bitcoin receive address. Legacy bitcoin addresses begin with 1 while SegWit bitcoin addresses begin with 3. Even after adding a SegWit wallet address, bitcoins sent to your previous legacy bitcoin address will still work. In addition, you can still send bitcoin from a SegWit wallet to a legacy wallet and vice versa since the transactions are still taking place on the same blockchain. But if you are sending bitcoins to and from a SegWit wallet, you can benefit from reduced fees.

BitPesa Acquires TransferZero

On February 8, 2018, BitPesa announced that it has acquired TransferZero, a Madrid-based online money transfer platform, which operates in over 200 countries using more than 50 currencies.

Why Did BitPesa Acquire TransferZero?

BitPesa, which is already operating in Africa and Europe, will be able to “set deep roots to UK and European licensing, bank accounts, and integrations” through this acquisition, according to the company’s statement on its blog.

“Europe is a hub for global remittance and payments companies. Digital currencies and decentralized technology have hit critical mass in the financial services and payments space. It is no longer a question of whether this technology will have staying power [but] which specific technology and what product iteration will launch and scale first […],” Elizabeth Rosiello, founder and CEO BitPesa said.

“BitPesa has the support of top-tier, institutional investors and a network that will help to bring TransferZero’s technology to the next level. With this support, we will be able to provide even more efficient transfers and user experience,” Luis Cambronero, former TransferZero CEO and present Managing Director, BitPesa stated.

Setting Up Infrastructure Across Europe and Africa is a Priority

“Setting up infrastructure across Europe and Africa has always been a focus of ours. […] We’ve just doubled our bank accounts, our infrastructure, and it’s licensed by the Bank of Spain as a payment institution. So we are fully compliant with PSD2 regulations […],” Rosiello said.

“This is truly a partnership where the whole is greater than the sum of the parts, allowing BitPesa to solidify our leadership in this space. By bringing our regional and technological expertise together, we will further accelerate our month-to-month growth,” Rossiello asserted.

TransferZero will neither change its name nor its headquarters. In addition, its employees will remain with Bitpesa.

This acquisition from an Africa-based bitcoin startup of a European fintech startup shows that leading African startups can make waves beyond the borders of the continent and create a positive impact on a global scale.
