What data do you hope to store using blockchain technology? I mean, you certainly can, but that would be wasteful. If the answer is yes then a blockchain solution may not be a good fit. Have you considered any privacy restrictions on the data you are dealing with?

For example, is the data personally identifiable information, such as healthcare data? Similarly, how will the data be entered into the system? Is the data going in solely under human direction? Is there some type of machine-machine communication going on? How are transactions handled? Transaction verification should be trivial, but if you are not dealing with public blockchains e.

If so, what are the additional steps taken as part of the verification process? Even if your idea involves the use of public blockchains you may want to include additional transaction verification steps that occur prior to interfacing with the public blockchain. Similarly, how is consensus handled in your blockchain solution? Inventing a new consensus algorithm is probably not a good idea.

This calculus changes if your blockchain solution does not make use of tokens that are native to your new fangled blockchain network. If you are not using tokens e. Does this interface with legacy systems? How do you envision your blockchain solution fitting into your existing business model? The blockchain solution will either interface with legacy systems or seek to replace legacy systems.

Both paths have their own pitfalls, and their own patent considerations. Along these lines, is your blockchain solution going to be solely internal to your business, client facing, or a combination of both? You need to consider exactly how your use of blockchain technology interacts with these internal systems and external systems. Who is allowed to participate? A blockchain network is made up of all sorts of different participants.

Have you figured out who can participate in your blockchain network and how? Do you use an existing blockchain network, such as Bitcoin or Ethereum? If so, have you considered privacy requirements for your data, and how they might be met on those networks?

If you are designing your own blockchain network, are there checks performed prior to participation in the network? What would those checks look like? Accordingly, do you have a validation process in place to validate information used as part of any checks on participation? This is less of an issue if you are spinning up some sort of permissioned blockchain where there is a certain level of trust afforded each participant.

Conclusion Blockchain technology is not a panacea for every problem you face. If that is not your situation, you need to think about at least the questions posed above, but probably many more. Posted on Denominated in Bitcoin You often see people in the Bitcoin community use the market capitalization of Bitcoin to compare it to the money supply of other countries.

In particular, the M1 Money Supply of countries is used as a metric to measure the value of all bitcoins against. These statistics are interesting, and certainly indicative of how far Bitcoin has come. At the same time, this is a narrow way to think about Bitcoin and its growth. There are no shortage of people that believe Bitcoin, or more generally cryptocurrencies, will replace fiat money in the future. Thinking in these terms, why limit Bitcoin to the M1 Money Supply?

Putting aside the probability, or desirability, of that outcome what does the world economy look like if it is denominated in bitcoin?

The programme, run by the Department of Student Governance and Development aims to assist students to develop skills needed for effective, ethical leadership. It explores and addresses the importance of diversity in daily interactions, encourages teamwork with others from diverse backgrounds, enhances skills in conflict resolution and communication, and encourages intellectual growth over a year-long period.

Beyond the Classroom BtC will introduce you to the requirements of leaders and assist you in developing the skills needed for effective leadership. A hard fork is a protocol upgrade that is not backward compatible. This means every node computer connected to the Bitcoin network using a client that performs the task of validating and relaying transactions needs to upgrade before the new blockchain with the hard fork activates and rejects any blocks or transactions from the old blockchain.

The old blockchain will continue to exist and will continue to accept transactions, although it may be incompatible with other newer Bitcoin clients. Since old nodes will recognise the new blocks as valid, a soft fork is backward-compatible. This kind of fork requires only a majority of the miners upgrading to enforce the new rules.

Bitcoin Cash has been hard forked since its original forking, with the creation of Bitcoin SV. What Is Taproot? Taproot is a soft fork that bundles together BIP , and and aims to improve the scalability, efficiency, and privacy of the blockchain by introducing several new features. MAST introduces a condition allowing the sender and recipient of a transaction to sign off on its settlement together. Schnorr Signature allows users to aggregate several signatures into one for a single transaction.

This results in multi-signature transactions looking the same as regular transactions or more complex ones. By introducing this new address type, users can also save on transaction fees, as even complex transactions look like simple, single-signature ones. Although HODL ers will probably not notice a big impact, Taproot could become a key milestone to equipping the network with smart contract functionality.

In particular, Schnorr Signatures would lay the foundation for more complex applications to be built on top of the existing blockchain, as users start switching to Taproot addresses primarily. If adopted by users, Taproot could, in the long run, result in the network developing its own DeFi ecosystem that rivals those on alternative blockchains like Ethereum.

What Is the Lightning Network? The Lightning Network is an off-chain, layered payment protocol that operates bidirectional payment channels which allows instantaneous transfer with instant reconciliation. It enables private, high volume and trustless transactions between any two parties. The Lightning Network scales transaction capacity without incurring the costs associated with transactions and interventions on the underlying blockchain.

A few years ago, the idea that a publicly traded company might hold Bitcoin on its balance sheets seemed highly laughable. The flagship cryptocurrency was considered to be too volatile to be adopted by any serious business. Since then, many others have followed suit, including EV manufacturer Tesla. MicroStrategy has by far the largest Bitcoin portfolio held by any publicly-traded company. The business analytics platform has adopted Bitcoin as its primary reserve asset, aggressively buying the cryptocurrency through and Is Bitcoin Political?

Bitcoin is becoming more political by the day, particularly after El Salvador began accepting the currency as legal tender. The country's president, Nayib Bukele, announced and implemented the decision almost unilaterally, dismissing criticism from his citizens , the Bank of England , the IMF , Vitalik Buterin and many others. Since the Bitcoin legal tender law was passed in September , Bukele has also announced plans to build Bitcoin City , a city fully based on mining Bitcoin with geothermal energy from volcanoes.

Countries like Mexico , Russia and others have been rumored to be candidates also to accept Bitcoin as legal tender, but thus far, El Salvador stands alone. On the flip side, countries like China have moved to heavily clamp down on Bitcoin mining and trading activities. In May , the Chinese government declared that all crypto-related transactions are illegal. This was followed by a heavy crackdown on Bitcoin mining operations, forcing many crypto-related businesses to flee to friendlier regions.

Surprisingly, the anti-crypto stance of the Chinese government has done little to stop the industry. According to data by the University of Cambridge , China is now the second-biggest contributor to Bitcoin's global hash rate, only behind the United States.

How Much Is Bitcoin? The current valuation of Bitcoin is constantly moving, all day every day. It is a truly global asset. From a start of under one cent per coin, BTC has risen in price by thousands of percent to the numbers you see above. Bitcoin is becoming more political by the day, particularly after El Salvador began accepting it as legal tender.

The programme consists of the following modules: Getting to know you. Though many of these individuals have condemned this issue and move on, some have prompted solutions: how do we make Bitcoin more energy efficient? Others have simply taken the defensive position, stating that the Bitcoin energy problem may be exaggerated.

The Bitcoin mining community also attests that the expansion of mining can help lead to the construction of new solar and wind farms in the future. Moreover, the energy consumption of Bitcoin can easily be tracked and traced, which the same cannot be said of the other two sectors. Those who defend Bitcoin also note that the complex validation process creates a more secure transaction system, which justifies the energy usage.

Another point that Bitcoin proponents make is that the energy usage required by Bitcoin is all-inclusive such that it encompasess the process of creating, securing, using and transporting Bitcoin. Whereas with other financial sectors, this is not the case. For example, when calculating the carbon footprint of a payment processing system like Visa, they fail to calculate the energy required to print money or power ATMs, or smartphones, bank branches, security vehicles, among other components in the payment processing and banking supply chain.

What exactly are governments and nonprofits doing to reduce Bitcoin energy consumption? Earlier this year in the U. S, specifically highlighting their concerns regarding fossil fuel consumption. Leaders also discussed the current debate surrounding the coal-to-crypto trend, particularly regarding the number of coal plants in New York and Pennsylvania that are in the process of being repurposed into mining farms. Aside from congressional hearings, there are private sector crypto initiatives dedicated to solving environmental issues such as the Crypto Climate Accord and Bitcoin Mining Council.

In fact, the Crypto Climate Accord proposes a plan to eliminate all greenhouse gas emissions by , And, due to the innovative potential of Bitcoin, it is reasonable to believe that such grand plans may be achieved. Bitcoin is the first decentralized, peer-to-peer digital currency. One of its most important functions is that it is used as a decentralized store of value. In other words, it provides for ownership rights as a physical asset or as a unit of account.

However, the latter store-of-value function has been debated. Many crypto enthusiasts and economists believe that high-scale adoption of the top currency will lead us to a new modern financial world where transaction amounts will be denominated in smaller units. The smallest units of Bitcoin, 0. The top crypto is considered a store of value, like gold, for many — rather than a currency. This idea of the first cryptocurrency as a store of value, instead of a payment method, means that many people buy the crypto and hold onto it long-term or HODL rather than spending it on items like you would typically spend a dollar — treating it as digital gold.

Crypto Wallets The most popular wallets for cryptocurrency include both hot and cold wallets. Cryptocurrency wallets vary from hot wallets and cold wallets. Hot wallets are able to be connected to the web, while cold wallets are used for keeping large amounts of coins outside of the internet. Some of the top crypto hot wallets include Exodus, Electrum and Mycelium.

Still not sure of which wallet to use? For example, if users A and B are disagreeing on whether an incoming transaction is valid, a hard fork could make the transaction valid to users A and B, but not to user C. A hard fork is a protocol upgrade that is not backward compatible. This means every node computer connected to the Bitcoin network using a client that performs the task of validating and relaying transactions needs to upgrade before the new blockchain with the hard fork activates and rejects any blocks or transactions from the old blockchain.

The old blockchain will continue to exist and will continue to accept transactions, although it may be incompatible with other newer Bitcoin clients.
