Blockchain is a form of distributed ledger technology, a digital system in which data is recorded across multiple places at the same time. Unlike traditional databases, DLTs have no central administrator or centralised data storage. They are transparent because the data is visible and, because they are automatically replicated and impossible to be tampered with, they are secure.

The main difference between blockchain and other forms of DLT is the way data is stored as ‘blocks’ – new transactions are added to the existing ‘chain’ of past transactions, hence the name ‘blockchain’. It is impossible to delete or modify information on the chain due to the replication of blocks across various locations.

Blockchain is mostly associated with cryptocurrency Bitcoin. Due to the inability to tamper with transactions, advocates say this makes the currency more secure and safer than traditional systems. It is maintained by a network of people referred to as ‘miners’, who receive rewards for solving complex mathematical equations that enable transactions to go through.

However, one of the major problems that has come to light has been the presence of illicit material buried in the Bitcoin blockchain, linking it to the dark web.

Other blockchain platforms can offer things like smart contracts, which are automatically implemented when specific conditions from all interested parties are reached, cutting the time involved and the risk of mistakes. Another use could be storing medical records, as patients can be confident their information cannot be changed. The technology can also be used in supply chains, voting and has the potential to used for storing property records.

Chancellor Rachel Reeves set markets on edge as she appeared visibly distraught in parliament on Wednesday. 

Legislative setbacks for the government have blown a new hole in the budgetary calculations at a time when the deficit is stubbornly large and the economy is struggling to grow. 

She appeared with Keir Starmer on Thursday and the pair embraced, but he had failed to give her his backing as she cried a day earlier.

A spokesman said her upset demeanour was due to a personal matter.

The idea of pound parity now seems less far-fetched as the risk grows that Britain may split away from the European Union without a deal.

Rupert Harrison, a fund manager at BlackRock, sees the risk of it falling to trade level with the dollar on a no-deal Brexit. The view echoes Morgan Stanley’s recent forecast that the currency can plunge toward $1 (Dh3.67) on such an outcome. That isn’t the majority view yet – a Bloomberg survey this month estimated the pound will slide to $1.10 should the UK exit the bloc without an agreement.

New Prime Minister Boris Johnson has repeatedly said that Britain will leave the EU on the October 31 deadline with or without an agreement, fuelling concern the nation is headed for a disorderly departure and fanning pessimism toward the pound. Sterling has fallen more than 7 per cent in the past three months, the worst performance among major developed-market currencies.

“The pound is at a much lower level now but I still think a no-deal exit would lead to significant volatility and we could be testing parity on a really bad outcome,” said Mr Harrison, who manages more than $10 billion in assets at BlackRock. “We will see this game of chicken continue through August and that’s likely negative for sterling,” he said about the deadlocked Brexit talks.

The pound fell 0.8 per cent to $1.2033 on Friday, its weakest closing level since the 1980s, after a report on the second quarter showed the UK economy shrank for the first time in six years. The data means it is likely the Bank of England will cut interest rates, according to Mizuho Bank.

The BOE said in November that the currency could fall even below $1 in an analysis on possible worst-case Brexit scenarios. Options-based calculations showed around a 6.4 per cent chance of pound-dollar parity in the next one year, markedly higher than 0.2 per cent in early March when prospects of a no-deal outcome were seemingly off the table.

Your UK residence status is assessed using the statutory residence test. While your residence status – ie where you live - is assessed every year, your domicile status is assessed over your lifetime.

Your domicile of origin generally comes from your parents and if your parents were not married, then it is decided by your father. Your domicile is generally the country your father considered his permanent home when you were born. 

UK residents who have their permanent home ("domicile") outside the UK may not have to pay UK tax on foreign income. For example, they do not pay tax on foreign income or gains if they are less than £2,000 in the tax year and do not transfer that gain to a UK bank account.

A UK-domiciled person, however, is liable for UK tax on their worldwide income and gains when they are resident in the UK.

• Area carpets or rugs are the easiest way to segregate spaces while also unifying them.
• Lighting can help define areas. Try pendant lighting over dining tables, and side and floor lamps in living areas.
• Keep the colour palette the same in a room, but combine different tones and textures in different zone. A common accent colour dotted throughout the space brings it together.
• Don’t be afraid to use furniture to break up the space. For example, if you have a sofa placed in the middle of the room, a console unit behind it will give good punctuation.
• Use a considered collection of prints and artworks that work together to form a cohesive journey.

There are numerous success stories of teen businesses that were created in college dorm rooms and other modest circumstances. Below are some of the most recognisable names in the industry:

1. Facebook: Mark Zuckerberg and his friends started Facebook when he was a 19-year-old Harvard undergraduate. 
2. Dell: When Michael Dell was an undergraduate student at Texas University in 1984, he started upgrading computers for profit. He starting working full-time on his business when he was 19. Eventually, his company became the Dell Computer Corporation and then Dell Inc. 
3. Subway: Fred DeLuca opened the first Subway restaurant when he was 17. In 1965, Mr DeLuca needed extra money for college, so he decided to open his own business. Peter Buck, a family friend, lent him $1,000 and together, they opened Pete’s Super Submarines. A few years later, the company was rebranded and called Subway. 
4. Mashable: In 2005, Pete Cashmore created Mashable in Scotland when he was a teenager. The site was then a technology blog. Over the next few decades, Mr Cashmore has turned Mashable into a global media company.
5. Oculus VR: Palmer Luckey founded Oculus VR in June 2012, when he was 19. In August that year, Oculus launched its Kickstarter campaign and raised more than $1 million in three days. Facebook bought Oculus for $2 billion two years later.
