Today is not tomorrow: early adopters are already living it today! Here are just a handful of vital Blockchain applications which have changed how people trust one another and transact value - stay tuned as we explore more use cases later!
Blockchain technology remains a topic that is confusing or intimidating to some individuals. In contrast, many still need to be convinced about how this technology will be applied. While such doubt is understandable given that we are still early into developing and adopting it as part of mainstream applications, people remain wary that its utility might decrease over time.
Blockchain is like the internet in its early years: no fad; an irreversible trend - you are one of its early adopters by reading this article and becoming part of this revolution! This article simplifies blockchain technology. Your "Introduction to Blockchain 101" provides a thorough yet understandable explanation. Understand everything there is to know about Blockchain, from its importance to how its operation occurs. This post will equip you to make informed and impartial decisions regarding blockchain technology while engaging family and friends in discussions.
Let's get going now and move forward with this project together.
Learn Blockchain for Beginners
Blockchain technology refers to an idea or protocol for running blockchains, making digital currencies (such as Bitcoin) possible. Blockchain is an electronic ledger with distributed ledger features that can be leveraged beyond cryptocurrency for various uses beyond cryptocurrency transactions.
Blockchain properties include immutability and distribution. Immutability means you can trust that its ledger will always remain accurate, while distribution protects the Blockchain from attack. Blocks record each transaction on the blockchain ledger; for instance, each block typically stores over 500 Bitcoin transactions on Bitcoin's Blockchain.
Information in one block depends upon the information in another block and is connected; over time, this linkage forms transactions that form what has become known as a blockchain - hence its name.
Blockchains are Available in Different Types
Four types of Blockchains exist:
1. Blockchains for Public Use
Blockchains are decentralized networks of computers accessible to anyone for verification or transaction request; miners who verify transactions receive rewards as rewards for verifying them.
Public blockchains operate according to either proof-of-work or proof-of-stake consensus models (to be discussed later). Ethereum (ETH) and Bitcoin (BTC) are famous examples of public blockchains.
2. Private Blockchains
Access to private blockchains is limited, requiring their administrator's permission to join. They're typically managed by one entity - Hyperledger is one such permissioned blockchain solution.
3. Consortia or Hybrid Blockchains?
Consortiums combining public and private chains contain centralized and decentralized elements; examples include Energy Web Foundation (EWF), Dragonchain and R3.
Note: Although these terms seem interchangeable, others make distinctions, while some consider both terms identical.
4. Sidechains
Sidechains are blockchains that operate parallel to leading chains. A sidechain enables digital asset transfers between chains while improving scalability; one such sidechain example would be Liquid Network.
What is a Public Blockchain? (Step by Step)
Ledgers were created as part of our society to keep track of information. Ledgers can serve many functions; real estate uses them for tracking home construction or sale dates, while bookkeeping uses ledgers as an accounting record of business transactions. Double-entry accounting is the preferred way of recording transactions in bookkeeping. While double-entry is considered more accountable and transparent, there can be some potential pitfalls.
Traditional ledgers allow recordkeeping to be easily altered; you can edit, delete or even add records as you please - meaning it may be harder for users to trust that information stored therein is accurate.
Public Blockchain answers both of these concerns - as well as trust issues - by expanding upon traditional accounting models with triple-entry bookkeeping. All transactions made using public blockchains are sealed cryptographically using third-party transactions, then stored into blocks and verified via distributed consensus systems. Consensus mechanisms ensure that new blocks are added to a blockchain network, with Proof-of-Work (PoW) as one such consensus mechanism.
Mining isn't unique to blockchains; instead, it serves as one type of consensus mechanism among them - currently used by Bitcoin and Ethereum; however, Ethereum plans to transition away from mining toward proof-of-stake (PoS) by 2022. Bitcoin works like this: when making transactions using it, a fee in Bitcoins must be paid to a computer network that will confirm your transactions before adding them together into blocks for further processing.
Computer nodes (node nodes) validate this block of transactions by solving complex math problems to generate hashes - 64 digit hexadecimal values with hashing algorithms based on these equations. Your transaction fee and all fees associated with that block will comprise your miner's reward - simple! This process should go as quickly and seamlessly as possible.
Each new block added to the system will receive its cryptographic key; these new keys can be obtained by applying previous keys to mathematical formulas. As blocks are added to the system, their security increases with each addition. Anyone caught editing records is ignored; information in all subsequent blocks relies on previous blocks forming the secure blockchain network.
Below is a diagram depicting house records stored on blockchain technology. Block 2 generates new keys once all information (including block 1's key) is input into its formula; similarly, after Block 3 has received all data ( including keys from both blocks 1 & 2), it too provides new keys - this continues until all three blocks (including their combined keys ) provide keys - this process continues indefinitely.
Proof of Work (PoW). Proof of Stake
Public blockchains operate using consensus mechanisms - processes for validating and verifying transactions without needing third-party involvement like banks - like consensus voting mechanisms to perform this function.
PoW and PoS both fall under this heading; their end goal remains the same - to reach a consensus on an acceptable transaction -but their methods differ drastically.
What is PoW (Positive Outcomes)?
Bitcoin and Ethereum still use Proof-of-Work as their original consensus method, although Ethereum plans on transitioning away from this model in 2022. PoW relies heavily on cryptography - mathematical equations only computers can solve. This system can be best understood by adding blocks to the Bitcoin Blockchain in section one above.
PoW has two significant drawbacks. First, it consumes considerable energy while only processing seven transactions simultaneously (Bitcoin uses eight). Transaction times usually range from 10 minutes for average transactions - more if congestion exists on the network. However, Bitcoin's 10-minute transaction delays are minor compared to sending money all around the globe or clearing checks which often take days!
PoW was not the only consensus mechanism designed to address issues surrounding PoW voting systems; Popular solutions also include PoS.

What is PoS (Point of Sale)?
PoS utilizes cryptographic algorithms to authenticate transactions, with validators' selection determined based on coin holdings - or "stake." Blocks do not produce rewards, and individuals don't technically mine them; instead, the blocks are "forged" through an interactive process by those participating in them.
As stakes become more extensive, so do their mining powers and chances of selection as block validators. Other selection methods can also help ensure that those with the most significant number of coins only sometimes win selection. Examples include random block selection, coin age selection and selecting forgers according to stakes and hash values. NEO and Dash offer faster transactions at reduced costs; payments can be sent and received using either of them within seconds.
The Scalability of Blockchain Trilemma - Decentralization Security and Scalability
As blockchain projects typically aim to combine security, decentralization and scalability - three characteristics developers strive for - finding a balance among these aspects is always challenging without one becoming compromised. Vitalik Buterin, the founder of Ethereum, coined this idea of an impassibility issue known as the scalability dilemma. Explore these ideas and their associated tradeoffs further:
Decentralization
Decentralization does not involve one centralized authority; decisions are reached through consensus between distributed computers. However, Bitcoin offers one crucial tradeoff. Transactions take longer due to multiple confirmations required before being confirmed, contributing significantly to Bitcoin's slowness.
Scalability
Scalability refers to how effectively a system handles increasing transaction levels. To remain effective over time and accommodate growing numbers of users effectively.
Here is an estimate of how many transactions Ethereum, Bitcoin and credit card providers can process per second:
- Bitcoin: seven per second.
- Ethereum: 30 cents per second.
- Credit Cards: The maximum credit card transaction speed is 5,000 per second, with an option to go higher if necessary. Visa can, for instance, process 24,000 transactions every second.
Scalability often comes at the Cost of decentralization; EOS offers a maximum of 4000 TPS capacity but has received criticism for being overly centralized.
The Security of Your Own Home
Security in Blockchain refers to its ability to withstand attack from potential attackers, with numerous exchanges having their source code and databases compromised, indicating that developers may prioritize decentralization and scalability at the expense of security.
What is the Difference Between Bitcoin and Ethereum Blockchains?
Bitcoin and Ethereum represent two of the biggest cryptocurrencies; thus, comparing and contrasting them makes sense.

Bitcoin Basics
Bitcoin is a decentralized peer-to-peer payment network that enables individuals to receive and send bitcoins without bank involvement or needing an intermediary as the single cryptocurrency on the Bitcoin Network. The digital currency traded under its ticker "BTC" serves as its unit of value on this payment network.
Nodes are responsible for upholding PoW consensus (or mining), or as is more often called for adherence to it (i.e., mining occurs). While Bitcoin might initially seem complex, it becomes clear when broken down into three factors.
- Peer-to-Peer Payment System: You can transfer money from one company or person to another (BTC) without using a bank. This is a faster and more cost-effective way to send money than traditional methods.
- The Internet is a decentralized network, meaning no one party cannot control it.
- Store of value similar to gold: (often called Digital Gold) but easier to move than gold.
Ethereum Basics
Vitlaik Anderin, an original Bitcoin developer, decided in 2013 to develop Ethereum after meeting other Bitcoin developers and realizing its limitations.
Ethereum is a decentralized public network using nodes where users can send and receive Ether, its native cryptocurrency - just like in Bitcoin.
This network was intended more as an environment for smart contracts and decentralized apps (dapps) than an ordinary payment solution.
Ethereum Blockchain is a decentralized app or software program that facilitates intelligent contracts - contracts that automatically execute themselves once certain conditions (written in computer code) have been fulfilled - such as when one dies; for instance, a smart contract could automatically distribute part of their Bitcoins upon your death to designated recipients.
Ethereum Blockchains vs. Bitcoin Blockchains
Summary: Bitcoin and Ethereum are peer-to-peer decentralized public systems relying heavily on cryptography with digital ledgers for data storage. Read through this post for a comparison between Ethereum and Bitcoin.
Different blockchain platforms each serve different functions and capabilities: Bitcoin is a decentralized payment system and value store; its blockchain records transactions. On the other hand, Ethereum allows smart contracts, apps, and other features to be developed on its blockchain network.
Blockchains: What are the Benefits of Using them Over Traditional Finance?
- Untrusted: Blockchain is unchangeable, automating transactions that are trusted between parties who don't need to be acquainted. The transaction is only carried out when both parties meet the pre-programmed conditions.
- Unstoppable: A transaction initiated once the conditions programmed in a blockchain protocol have been met cannot be reversed, altered, or stopped. Nothing - not even a bank or government - will stop the transaction from executing.
- Unchangeable Records in a blockchain can't be altered or changed - Bitcoin was never hacked. A new block is added after a complicated mathematical problem has been solved, and the consensus system verifies it. The formula used to create each new block results in a unique cryptographic key for the block.
- Decentralized: The network is not maintained by a single entity. The Blockchain is not centralized, and decisions are taken by consensus. Decentralization ensures that people can quickly build and access the blockchain platform. There are also multiple failure points.
- Less Cost In the conventional finance system, you must pay third parties like banks to process transactions. This eliminates intermediaries, and fees are reduced. Some systems even return fees to stakers and miners.
- Peer-to-peer: Bitcoin allows you to send money anywhere, anytime, directly, without an intermediary like a financial institution charging fees for transactions and handling.
- Transparent: Since public blockchains are free software, anyone can access them and view the source code of transactions. The code can be used to create new applications or to suggest code improvements. Consensus is used to accept or reject suggestions.
- Universal Banking: Two billion people worldwide do not own a bank. Anyone can use the Blockchain as a way to store cash, which is a good solution for those who do not have a bank account.
What are the Disadvantages of Blockchains?
Blockchains that are open and public come with risks and challenges. The following are the most common concerns.
1. Environmental Impact
Blockchain networks like Bitcoin require significant electricity resources for transaction validation, which has an environmental impact. Bitcoin consumes more energy than small or mid-sized European nations combined. At the same time, mining could threaten China's goals for climate change mitigation.
Some contend that Bitcoin meets higher environmental protection standards than anything else today, especially considering how its blockchain counterpart can provide alternatives to traditional financial systems that use more energy and have more significant environmental impacts than ever. Galaxy Digital recently conducted an analysis indicating that Bitcoin uses only half as much energy as traditional banking systems, making its adoption potentially an environmental win.
No one would dispute that carbon footprint reduction should be one of our top priorities (something already accomplished with mining farms switching to solar panels and El Salvador's President calling for plans to use volcanic energy for bitcoin mining). Evaluating the costs, environmental effects, and benefits associated with Blockchain is essential in reaching an informed decision.
2. Personal Responsibility
Blockchain and cryptocurrency offer many advantages; their most significant disadvantage is controlling how money is spent when purchasing or mining them. As it's great being your bank, if you lose access to your wallet due to forgetting the seed phrase - words used to access it - there is no way back - unlike banks where password reset options may exist - meaning your funds have gone forever!
Undoubtedly, an impressive portion of Bitcoin has gone irretrievably missing; estimates put this figure as 20-25% or roughly approx 3.7 Million Bitcoins out there that may no longer exist permanently.
3. Growing Pains
Decentralization comes at a price when it comes to scaling. While public blockchains may be more cost-efficient than their banking system counterpart, trying to expand them globally causes speed inefficiencies; as a result, Bitcoin and Ethereum only manage seven transactions simultaneously, while Visa can handle 24,000.
As companies look for solutions that increase transaction speeds and scalability, various innovations are being created to speed them up and ensure smooth operations. Lightning network is one such innovative Layer 2 solution developed on Ethereum to speed transactions off of its Blockchain, while many innovative Layer 2 solutions (L2), such as rollups as well as zero-knowledge side chain proofs, are also under development to expand these efforts.
4. False Narratives
Some cryptocurrencies are being utilized for illegal activity. Silk Road was an iconic example: individuals used Bitcoins there to launder funds and purchase drugs illegally. Criminal activity associated with other currencies, like the Dollar, would also occur here.
False assumptions that cryptocurrency use will only ever be for illicit activities delay adoption, which could ultimately prove hugely advantageous to everyone - including financial services firms and their customers.

Top 8 Blockchain Trends for 2023
Blockchain technology is an architectural system in which data blocks are securely and cryptographically linked together, often known as a decentralized ledger. Blockchain developers support decentralization by allowing everyone to own and engage their businesses without interference from others - read this article to explore which trends in Blockchain may shape the industry by 2023.
Blockchain is the latest revolutionary technology to radically alter our way of living, following in the footsteps of the internet and social media, which have transformed society and our daily lives. Within its database, transactions and contracts can be stored safely in blocks connected by encrypted links; each block is encrypted, unchangeable, timestamped and secure, even without an official watchdog to supervise it.
One major trend in Blockchain is predicted for 2022 - 1 in 4 unicorns will consist of companies focused on Blockchain. What does its future hold, and what are your predictions for its development?
1. The credibility of Decentralized Autonomous Organisations (DAOs)
While Web3 continues to expand, 2023 will see an even more substantial shift from traditional organizational structures toward DAOs as it accelerates. Members from different nations can collaborate using DAOs without dealing with complex paperwork associated with setting up multi-national entities or hiring foreign workers; many leading decentralized apps or dApp developers are adopting DAOs as de facto models for collaboration among their users.
Many companies provide DAO creators with services specifically tailored for them, like Singapore-based Poko, which assists creators in launching, raising funding and deploying DAOs quickly compared to starting up businesses in emerging markets.
2. Fewer Barriers to Entry, Thanks to Blockchain-as-a-service
As-a-service networks are encouraged to adopt cloud services due to their affordability and adaptability, making the development of blockchain apps and smart contracts quicker, thus decreasing the time to market.
Blockchain as a Service (BaaS) helps businesses bypass the costs associated with building their network and focus on optimizing functionality and increasing revenue while keeping an efficient network via providers.
NIFTRON, based in the U.K., offers a platform for Blockchain as a service (BaaS). Their software development kit (SDK) enables businesses to leverage this emerging technology while building apps using plug-and-play modules. Furthermore, their platform handles transactions, user accounts and tokenization of data for users.
3. Increased Adoption of the Technology in Public Sectors
Distributed Ledger Technologies (DLTs) will become a critical trend within Blockchain. DLTs offer several benefits over traditional paper systems, including greater openness and security using cryptography.
Government organizations can quickly improve constituent communication and management by making use of blockchains in creative ways. Blockchain can also assist government forms processing and monitoring chain of custody issues.
4. Environmentally Friendly use will be Promoted by the Industry
Blockchain's high energy usage hurts the environment. Most modern cryptographic protocols also consume large amounts of electricity; according to an index maintained by the University of Cambridge, cryptocurrency mining such as Bitcoin accounts for 0.5% of total energy use worldwide--more than Sweden's annual power use!
By 2023, energy-sensitive network architectures and carbon offsets will make adopting environmentally responsible blockchain technologies simpler. Proof of Stake and other eco-friendly algorithms will facilitate the creation of eco-friendly blockchains. Ethereum may implement Proof of Stake later this year - one of its largest blockchain networks has already done so!
5. Central Bank Digital Currencies: The Rise and Rise of CBDC
CBDCs can introduce groundbreaking breakthroughs on Blockchain that affect all stakeholders. Central Banking Institution Digital Currencies are digital tokens similar to cryptocurrency created by centralized bank systems linked with national fiat money systems and used as digital currencies within those economies.
CDBC could replace the U.S. Dollar as the decentralized currency. Over 95% of the global GDP is investigated by CDBC. Fifty countries, including Jamaica, Nigeria and South Korea, India, Russia and Japan, have advanced prototypes or developments or implementations. CDBCs have generated quite a buzz in the marketplace, and it can safely be predicted that their popularity will only grow until 2023.
6. Investment in Metaverse: A Cautious but Steady Approach
Metaverse has earned praise from advertisers, tech firms and pundits as an innovative force that promises to change lives for good. Metaverse refers to an interactive digital world with immense economic and societal potential, while "verse" denotes more directly to our universe.
The Metaverse is an immersive 3D decentralized world with multiple virtual spaces connected via blockchain technology and non-fungible tokens (NFT). It acts like an autonomous online world that doesn't rely on one vendor alone for operation, thus offering collaborative experiences without being directly controlled by any entity. Metaverse transactions will occur using blockchain-based tokens while serving as its operating medium for transactions within it.
Metaverse is "advancing with gusto" despite potential losses. Expect significant tech firms to become even more present by 2023.
7. Ricardian Contracts are a New Middle Ground for Traditional and Innovative Contracting
Ian Grigg first introduced the concept of Ricardian Contracts to blockchain platforms back in 1995. Since then, they have become widely utilized and can serve as rules and conditions of interaction among multiple people. Signing and hashing these digital agreements on each blockchain platform is possible.
Ricardian Contracts are legal documents written for human understanding that, once signed and accepted by both parties, become machine-readable contracts that outline goals and actions to take. Signing and validating are accomplished using cryptographic hashes for security and ease. Ricardian contracts will overtake intelligent contracts shortly due to increased trust between parties in blockchain transactions, as the Ricardian Contract binds all involved to it.
8. Blockchain Federated for Institutional Use
Federated Blockchain (AKA Consortium Blockchain) is an upgrade on private blockchains; one organization runs them, and new users need authorization before uploading files or viewing files on them; however, with Federated Chain (or Consortium Chain), all functionality remains but is managed by multiple organizations at once.
Federated Blockchains offer less decentralization and more excellent centralization than public and private networks. Still, more centralization, when compared with individual ones - provides an ideal alternative to organizational groups where decision-making power is spread among various members.
The "hybrid paradigm" allows for seamless collaboration. Furthermore, its security benefits enable all nodes to monitor each other - among several central federated Blockchains available today, Hyperledger Corda and Quorum are notable examples of this approach.
Consensus indicates a buoyant market for Blockchain in 2023. Some investors may adjust their spending while enterprise and blockchain applications continue to flourish. Given this complex environment, you must remain mindful of any adverse trends within cryptocurrency, as these will have lasting implications for industry impact over several months.
