How blockchains could change the world
Few people understand what it is, but Wall Street banks, consultants, and celebrities are buzzing about blockchain technology. It's hard to remove blockchain from Bitcoin, so we'll start with Bitcoin as we work to understand this technology's potential.
Download our free report to get all the trends. The impact of blockchain tech could be huge. Big corporations — like Walmart and Pfizer — have completed blockchain pilots, with many more partnering on projects ranging from remittance to title transfer.
The tech looks set to only grow in importance. Blockchain technology offers a way for untrusted parties to reach a consensus on a common digital history. Blockchain technology solves this problem without using a trusted intermediary. This explainer will offer simple definitions and analogies for blockchain technology. It will also define Bitcoin, Bitcoin Cash, Ethereum, Litecoin, Dogecoin, Cardano, XRP, stablecoins, non-fungible tokens, decentralized autonomous organizations, blockchain, and initial coin offerings.
For a deep dive into how Ethereum works specifically, you can read our What Is Ethereum explainer. Lastly, this report will make clear the distinctions between distributed ledger technology and blockchain, and highlight where these technologies have an application — and where they do not.
The financial crisis caused a lot of people to lose faith in banks as trusted third parties. Many questioned whether banks were the best guardians of the global financial system. Bad investment decisions by major banks had proved catastrophic, with rippling consequences.
Bitcoin is a decentralized, public ledger. There is no trusted third party controlling the ledger. Anyone with bitcoin can participate in the network, send and receive bitcoin, and even hold a copy of this ledger if they want to.
The Bitcoin ledger tracks a single asset: bitcoin. The ledger has rules encoded into it, one of which states that there will only ever be 21M bitcoin produced. Because of this cap on the number of bitcoins in circulation, the cryptocurrency is designed to be resistant to inflation stemming from a lack of scarcity. Bitcoin is politically decentralized — no single entity runs bitcoin — but all participants nodes agree on the state of the ledger and its rules.
Bob now has one token, and Alice has zero. The transaction is complete. Alice and Bob do not need an intermediary to verify the transaction. But what if the same transaction were digital? Alice sends Bob a digital arcade token — via email, for example. Bob should have the digital token, and Alice should not. Not so fast. What if Alice put the same digital token online for all to download? After all, a digital token is just a string of ones and zeros.
One answer: a ledger. This ledger will track a single asset: digital arcade tokens. When Alice gives Bob the digital token, the ledger records the transaction.
Bob has the token, and Alice does not. Now, they face a new problem: whose job will it be to hold the ledger? What if Dave decides to charge a fee that neither Alice nor Bob want to pay? Or, what if Alice bribes Dave to erase her transaction?
Maybe Dave wants the digital token for himself, and adds a false transaction to the ledger in order to embezzle it, saying that Bob gave him the token? Think back to the first physical transaction between Alice and Bob.
Is there a way to make digital transactions look more like that? One approach: Alice and Bob could distribute the ledger to all their trusted friends, not just Dave, and decentralize trust.
Because the ledger is digital, all copies of the ledger could sync together. If a simple majority of participants agree that the transaction is valid e. When a lot of people have a copy of the same ledger, it becomes more difficult to cheat. If Alice or Bob wanted to falsify a transaction, they would have to compromise the majority of participants, which is much harder than compromising a single participant.
And even if Alice bribes Dave to change his copy of the ledger, Dave only holds a single copy of the ledger; the majority opinion would show the digital token was sent. In sum, this distributed ledger works because everyone is holding a copy of the same digital ledger.
The more trusted people that hold the ledger, the stronger it becomes. Such a ledger allows Alice to send a digital token to Bob without going through Dave. In a sense, she is transforming her digital transaction into something that looks more like a physical one in the real world, where ownership of an asset is tangible and obvious. You may have noticed a key difference between the above example and Bitcoin. In contrast, Bitcoin is entirely public, and anyone can participate.
How can we avoid bad actors corrupting the ledger? A public ledger would allow for many more participants. The more participants, the stronger the ledger becomes. Because Bitcoin expands beyond trusted participants and gives anyone access, it opens itself up to bad actors attempting false transactions. However, Bitcoin is free and open to anyone, trusted or not, like a Google document that anyone can read and write to. Bitcoin offers a solution: reward good actors and scare off bad ones, a classic carrot and stick act.
In simple terms, certain Bitcoin participants are incentivized to do the dirty work and maintain the network. For doing this work, these miners are rewarded with bitcoin. With a single bitcoin worth tens of thousands of dollars, this can be a strong incentive.
Further, if the Bitcoin community became aware of the hack, it would likely cause the price of bitcoin to drop steeply. These factors help make it more likely that such an attack would be economically self-defeating. Proof of Work PoW is the consensus mechanism that underpins the security of the blockchain and the legitimacy of the blocks that are mined, with the aim of building trust in a decentralized network.
To mine a new block, miners solve a complex puzzle that requires non-trivial levels of computing power. Once a miner finds a solution, the new block is broadcast to the network for verification and appended to the blockchain. The PoW protocol makes such an attack on the blockchain network economically infeasible. For a miner to execute a double-spend attack, the miner must mine a block containing a fraudulent transaction and force a fork in the blockchain.
While the PoW makes blockchain more secure, it is at the same time extremely energy-intensive — raising environmental and ethical concerns. The PoW model has also led to the creation of large mining pools in countries where electricity is less expensive. This shift towards the centralization of mining has caused some to question whether Bitcoin is truly decentralized. Halving reduces the amount of bitcoin awarded per block to miners by half.
The mining reward was halved from For investors, this event was highly anticipated because the first 2 halvings were followed by a bull market, driven by the combination of higher demand and a reduced new supply of bitcoin.
The global market crash in March triggered by Covid also led to the prices of crypto assets dropping in one of the sharpest declines in history. However, in the months that followed, prices recovered along with safe-haven assets like gold, as investors looked to stores of value in response to market volatility.
Many of them seek to improve on Bitcoin or expand its capabilities. Other cryptocurrencies use different rules and engage with other economic models.
Hashes, public-private key encryption, segregated witness, and sidechains, among other elements, fall outside of the scope of this piece. Anyone can participate. To ensure its public, decentralized ledger remains secure, Bitcoin uses a blockchain. Blockchain technology offers a way for untrusted parties to reach agreement consensus on a common digital history. There are three main reasons. Effectively, Bitcoin uses a blockchain to decentralize payments. Where else could we use this database architecture to remove middlemen?
Are there other things that would benefit if they were decentralized? Land title is one. It could be useful for everyone to have access to a decentralized source of record saying who owns a given parcel of land. The approach could even have some humanitarian implications in scenarios where land has been redistributed without due process or compensation, such as during a war.
The concept is that once land ownership has been agreed upon, it could be recorded in a distributed ledger and would no longer be subject to counterclaims. The Republic of Georgia has already adopted a blockchain-based land titling system, with the goal of reducing fraud and corruption in real estate.
In the same vein, a blockchain could be used to establish proof of ownership over any number of physical assets — cars, art, musical instruments, and so on. A paper record of title is prone to forgery and physical degradation. A blockchain means there is no single entity controlling the ledger. Therefore, recording physical assets on a blockchain is a prime example of where the technology might come in handy to track ownership with a tamper-proof, neutral, and resilient system.
Blockchain technology could even prove applicable in virtual worlds. If a virtual world is created — for gaming, or for any number of other reasons — blockchain technology could allow users to purchase and own pieces of that virtual world, just like they might purchase a plot of land.
Blockchain tech could even play a role in running a metaverse.
Five myths about cryptocurrency
This op-ed was originally published by The Washington Post. Bitcoin, the original cryptocurrency, was launched in The surge in their prices earlier this year minted tens of thousands of cryptocurrency millionaires—at least on paper. Cryptocurrencies might turn out to be a massive speculative bubble that ends up hurting many naive investors. Indeed, many cryptocurrency fortunes have already evaporated with the recent plunge in prices.
Explaining Web3: From the blockchain and crypto to NFTs and the metaverse
In the early days, it was commonly thought that cryptocurrencies like Bitcoin were a safe haven for criminals because they were untraceable and entirely anonymous. But the question still remains, how anonymous is cryptocurrency? A cryptocurrency is a digital or virtual currency which is used as a medium of exchange. It is similar to real-world currency but for the fact it does not have any physical embodiment and uses cryptography, which makes it nearly impossible to counterfeit or double-spend. When you open a traditional bank account, the bank takes record of your KYC data. However, it is not mandatory to use a KYC cryptocurrency exchange to trade. In fact, a number of exchanges legally operate in jurisdictions that do not mandate KYC, placing them in a grey area in terms of legal obligations. The paradox of cryptocurrency is that its associated data creates a trail that can suddenly make your entire financial history public information. Every single transaction that takes place in Bitcoin is accessible to anyone who is on the network.
How Anonymous Is Cryptocurrency?
Crypto now is now legal in India. The tax would also apply to gifts of digital assets, with recipients being liable to pay the levy. She also said the central bank will introduce a digital currency in the next financial year using blockchain and other supporting technology. Sitharaman said that introduction of a central bank digital currency will give a boost, a big boost to digital economy. The announcement contrasts from November when the Indian government announced that it was introducing a bill in its Winter Parliament Session to ban private cryptocurrencies.
Web3 is the future, or a scam, or both
Jump to navigation. I don't remember the first time I heard about blockchain. I do, however, remember when I began to hear about it frequently. A couple of years ago, I was working on building tools for community land rights , when our partners and people at conferences began to ask us about it. A colleague and I sat down and said, "we need to figure out this blockchain thing," because we didn't even know how it was relevant, let alone what problems it might be able to fix. Before we started our research, I used to describe blockchain as "the technology that powers Bitcoin.
Blockchain and IP Law: A Match made in Crypto Heaven?
What impact could the technology behind Bitcoin have? According to Tapscott Group CEO Don Tapscott, blockchains, the technology underpinning the cryptocurrency, could revolutionize the world economy. In the early s, we said the old media is centralized. This has an awesome neutrality. It will be what we want it to be, and we can craft a much more egalitarian, prosperous society where everyone gets to share in the wealth that they create. Lots of great things have happened, but overall the benefits of the digital age have been asymmetrical.

Acknowledging that a large segment of the population is involved in crypto-related transactions, Finance Minister Nirmala Sitharaman in the Union Budget for has pulled crypto taxation from the shadows of ambiguity. The government has decided to bring virtual digital assets under the tax scanner by levying a 30 percent tax on their sale and purchase online. The announcement was met with a mixed bag of industry responses- some muted, some positive, but all of them calling out for further clarity on its nuances in the days to come. Says Edul Patel, CEO, and Co-founder of Mudrex, "The government has taken a conservative step towards the cryptos by announcing a 30 percent tax regime on income from digital assets, including the gifts or transferring of assets from one wallet to another owned by various individuals. Investors now need to report gains and losses that cannot be offset against any other sort of income.
Bitcoin price continued to rise on Monday. Expectations of tightening monetary policy helped spur a bearish downturn last month in cryptocurrency assets. On the other hand, Ether, the coin linked to ethereum blockchain and the second-largest cryptocurrency, rose more than 1. Acknowledging that a large segment of the population is involved in crypto-related transactions, Finance Minister Nirmala Sitharama in her Budget speech yesterday pulled crypto taxation from the shadows of ambiguity. The government has decided to bring virtual digital assets under the tax scanner by levying a 30 per cent tax on their sale and purchase online. The FM also specified that an additional 1 per cent TDS will also be levied on such crypto transactions that exceed a certain threshold, thereby establishing a trail of details. The subsequent amount or the virtual digital asset gift will be taxable in the hands of the recipient.
