In recent years, there has been a surge of terminology explaining various tech concepts. While some terms like crypto and NFT have been around for a while, others such as DeFi and DAOs are relatively new but are increasingly prevalent.
Whether you’re a tech novice or a seasoned veteran, trying to grasp these concepts can often feel like tackling a new language. To help bridge this gap, we have developed a guide consisting of concise explanations for common tech terms. Through this guide, readers can expect straightforward explanations that demystify complex concepts, making them more accessible to all.
In recent years, the digital landscape has witnessed a surge in innovative technologies reshaping various industries. Among these groundbreaking developments are blockchain, non-fungible tokens (NFTs), and decentralized autonomous organizations (DAOs). Understanding these concepts is essential as they redefine traditional paradigms of data management, asset ownership, and organizational governance.
At its core, blockchain technology revolutionizes data storage and transactional processes. Acting as a distributed ledger shared among network nodes, blockchains ensure secure and transparent record-keeping, primarily known for their role in cryptocurrency systems like Bitcoin. However, their applications extend beyond finance, promising immutable data storage across diverse industries.
Accompanying the rise of blockchain technology is the emergence of non-fungible tokens (NFTs), representing unique digital assets on a blockchain. Unlike cryptocurrencies, which are fungible and interchangeable, NFTs are indivisible and irreplaceable, enabling ownership verification and monetization of digital content ranging from artwork to virtual real estate.
Meanwhile, decentralized autonomous organizations (DAOs) represent a novel approach to organizational governance, leveraging blockchain technology to operate without centralized control. By enabling collective decision-making and resource allocation through smart contracts, DAOs empower participants to collaborate effectively in a transparent and decentralized manner.
This article explores the fundamental principles, applications, benefits, and challenges of blockchain, NFTs, and DAOs. Delving into their mechanisms, use cases, and potential implications, we uncover the transformative potential of these technologies in shaping the future of digital economies and organizational structures.
A blockchain is a distributed database or ledger shared among nodes in a computer network. Its main role is to securely and decentralize the record of transactions, notably in cryptocurrency systems, though its applications extend beyond this domain. Blockchains ensure the immutability of data, meaning it cannot be altered, across different industries.
As blocks within a blockchain cannot be changed, trust is primarily required during data input by users or programs. This reduces reliance on trusted third parties, like auditors or humans, which typically incur costs and errors.
Since Bitcoin’s inception in 2009, the use of blockchain technology has surged. It has facilitated the development of various cryptocurrencies, decentralized finance (DeFi) apps, non-fungible tokens (NFTs), and smart contracts.
If you’re familiar with spreadsheets or databases, understanding a blockchain won’t be too difficult. Essentially, a blockchain functions similarly to a database in that it stores information. However, the crucial distinction lies in how the data is organized and accessed.
In a blockchain, there are programs known as scripts that handle typical database operations like inputting and retrieving information, as well as storing it securely. One key feature of a blockchain is its distribution across multiple machines. This means that numerous copies of the blockchain exist on different computers, and for the blockchain to be considered valid, all these copies must match. This distributed nature ensures transparency and security within the blockchain system.
In the process of blockchain operation, transaction data is gathered and recorded within a block, akin to data being stored in a cell within a spreadsheet. Once the block reaches its capacity, the data undergoes encryption using an algorithm, resulting in the generation of a hexadecimal number known as the hash.
Subsequently, this hash is incorporated into the subsequent block header and encrypted alongside other data within the block. This sequence of actions leads to the formation of a chain comprising interconnected blocks, hence the term “blockchain.”
Transactions undergo a structured process, varying depending on the blockchain in question. Take Bitcoin’s blockchain, for instance. When you initiate a transaction through your cryptocurrency wallet—a tool facilitating interaction with the blockchain—it sets off a series of steps.
In Bitcoin’s network, your transaction enters a memory pool, where it waits in line until a miner or validator processes it. Once included in a block, alongside other transactions filling up the block, it undergoes encryption through an encryption algorithm before the mining process commences.
In the network’s collaborative effort to tackle the hash, each participant strives to “solve” it, with everyone generating a unique hash except for the “nonce,” or number used once.
Initially, every miner commences with a nonce set to zero, appended to their hash. If this resulting number fails to meet the target hash criteria, the nonce is incremented by one, and the process repeats until a valid hash is produced, thereby declaring the miner as the winner of the competition and entitled to the reward.
This process of generating random hashes until a specific target is achieved constitutes the “proof-of-work” mechanism, verifying that the miner has indeed put in the effort. The computational intensity of validating hashes is why the Bitcoin network consumes significant computational power and energy resources.
Upon the closure of a block, a transaction is deemed complete. However, confirmation of the block requires validation by five subsequent blocks, which typically takes around one hour due to the network’s average block generation time of just under 10 minutes.
It’s worth noting that not all blockchains adhere to this exact process. For example, the Ethereum network employs a different approach where a validator is randomly selected from users with staked ether to validate blocks, leading to a faster and less energy-intensive process compared to Bitcoin’s method.
In blockchain technology, data within a database is dispersed across multiple network nodes—computers or devices equipped with blockchain software—located at various points. This distribution not only ensures redundancy but also upholds the integrity of the data. For instance, attempts to tamper with a record in one instance of the database would be thwarted by other nodes in the network. Consequently, no single node possesses the authority to modify the information contained within the network.
Thanks to this decentralized distribution, coupled with cryptographic evidence of work performed, the information and historical data (such as transaction records in cryptocurrency) become immutable. While blockchain records commonly comprise transactional data, they can also accommodate diverse information types, including legal contracts, governmental identifications, or a company’s inventory.
Due to the decentralized structure of the Bitcoin blockchain, all transactions are openly visible, accessible either through personal nodes or via blockchain explorers, which enable real-time monitoring of transactions. Each node maintains its copy of the blockchain, updated with each confirmed block addition. Consequently, tracking the movement of bitcoins is feasible, offering a high level of transparency.
For instance, instances of exchange hacks resulting in significant cryptocurrency losses have occurred in the past. Despite the anonymity of the perpetrators—save for their wallet addresses—the crypto they pilfered remains traceable because these wallet addresses are publicly available on the blockchain.
It’s important to note that while records stored within the Bitcoin blockchain (and most others) are encrypted, only the address holder can unveil their identity. Thus, blockchain users can uphold their anonymity while ensuring transparency in transactions.
Blockchain technology ensures decentralized security and trust through several mechanisms. Firstly, new blocks are consistently added to the end of the blockchain in a linear and chronological manner. Once appended, previous blocks are immutable and cannot be altered.
Any modification to data within a block results in a change to the block’s hash. Since each block contains the hash of the preceding block, any alteration would cascade through subsequent blocks. Consequently, attempts to tamper with a block would be detected by the network, as the altered block’s hash would fail to match.
However, it’s important to acknowledge that not all blockchains are impervious to breaches. While they rely on code to establish their renowned security, vulnerabilities in this code can be exploited.
Consider a scenario where a hacker operates a node within a blockchain network, intending to manipulate the blockchain and abscond with others’ cryptocurrency. To succeed, they would need to alter their copy convincingly enough to persuade other nodes of its validity. This feat would require controlling a majority of the network—a so-called 51% attack. However, executing such an attack is exceedingly challenging due to the rapid hashing rate of these networks. For instance, on April 21, 2023, the Bitcoin network boasted a staggering hashing rate of 348.1 exahashes per second.
Non-fungible tokens (NFTs) represent assets that have been tokenized using blockchain technology. These tokens are unique identifiers generated from metadata through encryption functions. While the tokens themselves are stored on a blockchain, the actual assets they represent are stored elsewhere. The distinct link between the token and the asset is what renders NFTs unique.
NFTs can be bought, sold, or exchanged for money, cryptocurrencies, or other NFTs, with their value determined by market demand and the preferences of owners. For instance, one could tokenize a photo of a smiley face drawn on a banana and assign specific rights to the token. The individual possessing the private keys to that token would then assume ownership of the associated rights.
It’s important to note that while cryptocurrencies also operate using tokens, the primary distinction lies in fungibility. Cryptocurrencies within the same blockchain are interchangeable, making them fungible. Conversely, while two NFTs may appear identical on the surface, they are non-interchangeable due to their unique properties.
Non-fungible tokens (NFTs) have a history predating their recent surge in mainstream popularity. The first recorded sale of an NFT, “Quantum,” was in 2014, tokenized by Kevin McKoy on the Namecoin blockchain before being minted on Ethereum and sold in 2021.
NFTs are typically constructed following the ERC-721 (Ethereum Request for Comment #721) standard. This standard outlines protocols for transferring ownership, verifying transactions, and ensuring secure transfers within applications, among other specifications. Following the ERC-721 standard, the ERC-1155 standard was approved six months later, offering enhancements by consolidating multiple non-fungible tokens into a single contract, thereby reducing transaction costs.
NFTs are generated through a process known as minting, during which the asset’s details are encrypted and stored on a blockchain. At its core, the minting process involves creating a new block, validating the NFT information by a validator, and subsequently closing the block. Smart contracts are often integrated into this process to allocate ownership and facilitate NFT transfers.
During minting, each token is assigned a unique identifier directly linked to a specific blockchain address. Every token possesses an owner, and the ownership information, such as the address where the minted token resides, is publicly accessible. Even if multiple identical NFTs (akin to general admission tickets to a movie) are minted, each token bears a unique identifier, enabling it to be distinguished from others.
While numerous blockchains have the capability to create NFTs, they might be referred to by different names. For instance, on the Bitcoin blockchain, they are termed Ordinals. Similar to Ethereum-based NFTs, Bitcoin Ordinals can be bought, sold, and traded. However, the distinction lies in the fact that while Ethereum generates tokens for the asset, Ordinals entail serial numbers (identified as identifiers) assigned to satoshis—the smallest denomination of Bitcoin.
Similar to physical currency, cryptocurrencies typically exhibit fungibility, meaning they can be interchanged or traded one-for-one. For instance, on an exchange, one bitcoin holds the same value as another bitcoin, akin to how each dollar bill in U.S. currency is universally valued at $1. This fungible nature renders cryptocurrencies a secure medium for transactions within the digital economy.
However, non-fungible tokens (NFTs) disrupt this crypto paradigm by imbuing each token with uniqueness and irreplaceability. Unlike fungible assets, no two NFTs are identical or interchangeable.
They serve as digital representations of assets and are often likened to digital passports, each possessing a distinct, non-transferrable identity that sets it apart from other tokens. Additionally, NFTs offer extensibility, enabling the combination of multiple tokens to create a novel, unique NFT—a process known in the cryptocurrency realm as “breeding.”
One of the most renowned examples of NFTs is the phenomenon of cryptokitties. Introduced in November 2017, cryptokitties are digital renditions of cats, each possessing a unique identification on Ethereum’s blockchain.
These virtual felines are distinct from one another, with varying prices and attributes. They have the ability to “breed” among themselves, producing offspring with different attributes and valuations compared to their parents.
Shortly after their release, cryptokitties garnered a dedicated following, with enthusiasts spending millions in ether to acquire, nurture, and trade them.
While the initial NFT market primarily focused on digital art and collectibles, it has since diversified. Platforms like OpenSea, a popular NFT marketplace, offer a plethora of categories:
One of the most noticeable advantages of NFTs lies in their capacity to enhance market efficiency. By tokenizing physical assets, sales processes can be streamlined, eliminating the need for intermediaries. NFTs representing digital or physical artwork on a blockchain enable direct connections between sellers and their target audiences, potentially bypassing agents (provided artists can securely host their NFTs).
NFTs also offer opportunities for streamlined investing. For instance, consulting firm Ernst & Young developed an NFT solution for a fine wine investor, utilizing NFTs to safeguard provenance while securely storing wine in a controlled environment.
The tokenization of real estate presents another avenue for NFT utilization. Properties can be divided into distinct sections, each with unique characteristics and represented by an NFT. This approach simplifies real estate trading, traditionally complex and bureaucratic, by incorporating relevant metadata into unique NFTs associated with specific portions of the property.
Furthermore, NFTs can serve as representations of ownership in businesses, akin to stocks. Utilizing NFTs and blockchain for stock ownership offers advantages such as automated ownership transfers through smart contracts, streamlining administrative processes.
Security is another significant benefit of NFTs, particularly in identity protection. Storing personal information on an immutable blockchain ensures it remains inaccessible and secure, safeguarded by cryptographic keys.
Additionally, NFTs have the potential to democratize investing by fractionalizing physical assets. Tokenization enables multiple individuals to purchase shares of assets like paintings, granting them fractional ownership and democratizing access to investments previously reserved for the affluent.
To purchase NFTs, you typically need cryptocurrency supported by the exchange you’re using. Thus, having a digital wallet and some crypto on hand is essential. For example, platforms like OpenSea accept ETH, WETH, AVAX, USDC, and DAI. Additionally, other online NFT marketplaces, such as Rarible and SuperRare also facilitate NFT transactions.
Non-fungible tokens, like cryptocurrency, leverage blockchain technology and are generally resistant to hacking. However, the security of NFTs hinges on the safeguarding of your cryptographic keys. While blockchains themselves are robust, vulnerabilities may arise if keys are compromised or lost. Hence, adhering to the principle of “not your keys, not your coin” is crucial for securing both NFTs and cryptocurrency assets.
Fungibility pertains to the interchangeability of goods. For instance, imagine you have three notes, each adorned with an identical smiley face. When you tokenize one of these notes, it becomes distinct from the others—it becomes non-fungible. In contrast, the remaining two notes remain indistinguishable and can seamlessly substitute for one another.
A decentralized autonomous organization (DAO) represents a novel legal structure devoid of a central governing body, wherein members unite under a shared objective to advance the entity’s interests. Emerging alongside cryptocurrency enthusiasts and blockchain technology, DAOs adopt a bottom-up management approach, enabling collective decision-making.
The primary aim of decentralized autonomous organizations (DAOs) stems from the decentralized nature of digital currencies.
Unlike traditional currencies controlled by centralized institutions like governments or central banks, digital currencies operate across a network of computers, networks, and nodes, affording heightened levels of privacy and security.
Inspired by this decentralized paradigm, developers conceived the idea of DAOs in 2016 to facilitate oversight and management akin to corporations. However, the defining characteristic of a DAO lies in its absence of central authority; instead, leadership and decision-making are distributed among a collective group of participants.
DAOs heavily rely on smart contracts—logically coded agreements that dictate decision-making processes based on blockchain activity. For instance, these contracts can trigger actions such as adjusting circulating supply, burning reserve tokens, or distributing rewards to tokenholders, contingent upon specific decision outcomes.
The voting process for DAOs is transparently recorded on a blockchain, typically involving users selecting from mutually-exclusive options. Voting power is commonly allocated based on the number of tokens held by each user. For instance, a user possessing 100 tokens in the DAO would wield twice the voting influence compared to someone holding 50 tokens.
This approach is rooted in the belief that users with a greater financial stake in the DAO are inclined to act in its best interests. Consider a user holding 25% of the total voting power: while they could engage in malicious activities, doing so would jeopardize the value of their significant stake.
Furthermore, DAOs often maintain treasuries containing tokens that can be exchanged for fiat currency. Members of the DAO participate in voting to determine how these funds should be utilized. For example, DAOs focused on acquiring rare NFTs may vote on whether to allocate Treasury funds in exchange for these assets.
There are several compelling reasons why entities or groups of individuals might opt for a DAO structure. Some of the advantages of this management model include:
Decentralization: Decision-making within the organization is distributed among a collective of individuals, rather than being concentrated in a central authority. Unlike traditional structures where authority is held by a CEO or a small board, a DAO disperses power across a much broader user base.
Participation: Members of an entity feel more engaged and empowered when they have direct voting power on all matters. While individual voting influence may vary, a DAO encourages token holders to actively participate in voting, token burning, or utilizing their tokens to benefit the organization.
Transparency: Votes within a DAO are conducted via blockchain and are publicly visible. This transparency incentivizes users to act in the organization’s best interests, as their decisions are open to public scrutiny. Such transparency fosters accountability and discourages actions that may harm the community.
Community: DAOs promote global collaboration, allowing individuals from diverse backgrounds to unite in pursuit of a shared vision. With just an internet connection, token holders can engage with fellow owners worldwide, facilitating the creation of a vibrant and inclusive community.
While DAOs offer numerous benefits, they also come with notable limitations and challenges:
1. Speed: Unlike traditional companies where decisions may be swiftly made by a CEO, DAOs involve every user in the decision-making process, leading to longer voting periods. Coordination across different time zones and consideration of external priorities can further delay decision-making.
2. Education: DAOs face the challenge of educating a diverse user base about entity activities. Unlike a single CEO overseeing company developments, DAO token holders may vary widely in their educational backgrounds, understanding of initiatives, and access to resources. Ensuring effective communication and alignment among members with diverse perspectives can be challenging.
3. Inefficiency: Due to the need to educate voters, communicate initiatives, and onboard new members, DAOs risk becoming inefficient. Delays in decision-making and excessive administrative tasks can hinder effective implementation of changes, leading to inefficiencies in governance processes.
4. Security: Like all digital platforms utilizing blockchain technology, security is a paramount concern for DAOs. Implementing and maintaining robust security measures requires significant technical expertise. Without proper security protocols, there is a risk of invalid votes, compromised decisions, and breaches that may undermine trust in the DAO. Exploitation of vulnerabilities can result in theft of treasury reserves and loss of user confidence in the entity’s structure, potentially leading to user attrition. Even with measures like multi-signature or cold wallets, DAOs remain susceptible to exploitation and malicious attacks.
DAO Example: The DAO
The DAO was a groundbreaking organization characterized by its automation and decentralization. It functioned as a venture capital fund, operating on open-source code and eschewing traditional management structures or boards of directors. With a commitment to full decentralization, The DAO maintained independence from any specific nation-state, leveraging the Ethereum network for its operations.
Launched in late April 2016, The DAO originated from a month-long token crowd sale that garnered an astounding $150 million in funds. At its inception, this launch represented the largest crowdfunding campaign ever witnessed, marking a significant milestone in the evolution of decentralized autonomous organizations.
