In the simplest terms, a hash is like a digital fingerprint for data.
Imagine you have a piece of information—a document, a photo or even a piece of text. When you run this information through a hash function (a specific type of algorithm), it generates a unique string of characters called a hash. No matter the size of the original data, the resulting hash is always of a fixed length. This is a key feature of hash functions: They condense data into a fixed-size output.
Think of it like shredding a document and then encoding the resulting pile of shredded paper into a fixed-sized box. No matter how long or short the original document was, the box is always the same size, and it’s nearly impossible to reconstruct the original document from the box alone. Similarly, it’s computationally infeasible to revert a hash back into its original data.
Hashes are foundational to many blockchain technologies, including cryptocurrencies like Bitcoin and Ethereum. They are integral to how blockchain ensures the integrity and security of data. Here are some key reasons why hashes are so important in Web3:
Data Integrity: Hashes ensure that the data hasn’t been altered. When data is hashed, even the slightest change in the input (like changing a single letter in a text) will produce a completely different hash. This makes it easy to detect tampering or corruption.
The decentralized internet as we know it is possible through the use of hash functions, as demonstrated by the Interplanetary File System and its distributed hash table. IPFS uses hash functions to verify the integrity of all data shared to what has become known as the decentralized internet. In fact, Gala Founder’s Nodes power a large portion of this data, giving the Gala ecosystem a large share in the responsibility of web3’s future.
Blockchain Security: In blockchain, hashes are used to link blocks of data together. Each block contains the hash of the previous block, forming a chain. If someone tries to alter the data in a block, the hash of that block changes, which then changes the hash of the subsequent block, and so on. This makes it extremely difficult to alter any information in the blockchain without detection.
Efficient Data Storage: Hashes allow large amounts of data to be represented by a small, fixed-size string. This makes storing and verifying data in blockchain systems much more efficient.
Proof of Work: In cryptocurrencies like Bitcoin, hash functions are used in the mining process. Miners compete to find a hash that meets certain criteria (e.g., it must start with a certain number of zeros), which requires computational power. This process, known as “proof of work,” secures the network and adds new blocks to the blockchain.
How Hashes Work
To dive a bit deeper, let’s explore how a hash function works. A common hash function used in blockchain is SHA-256 (Secure Hash Algorithm 256-bit). When you input data into SHA-256, it generates a 256-bit (or 64-character) hash. No matter what data you input—a single letter or an entire book—the output is always 64 characters long.
For example:
The text “Hello, World!” might hash to something like a591a6d40bf420404a011733cfb7b190d62c65bf0bcda32b575a0f76c6e53a2e.
If you change it to “Hello, world!” (note the lowercase ‘w’), the hash could be 64ec88ca00b268e5ba1a35678a1b5316d212f4f366b247724e663cd0da0927d5.
This dramatic change in the hash output despite a minor change in input is known as the “avalanche effect,” a property that makes hash functions extremely secure, reliable and suitable for blockchain technology.
Hashes are used in various Web3 applications beyond just cryptocurrencies:
Smart Contracts: Smart contracts often use hashes to verify the integrity of data or ensure that certain conditions have been met.
Digital Signatures: When sending transactions on a blockchain, digital signatures use hash functions to securely sign and verify the authenticity of messages.
Non-Fungible Tokens (NFTs): NFTs often include metadata that is hashed to ensure the data related to the token (like the digital artwork it represents) remains unchanged.
In the world of Web3, hashes are like the glue that holds everything together. They ensure data integrity, provide security, and allow for efficient data handling. Whether you’re dealing with cryptocurrencies, smart contracts, or NFTs, understanding hashes is crucial to grasping how the blockchain works.

In the context of web3 and blockchain technology, nodes are essentially points within a network where data is processed, stored and communicated. Think of a node as a server that contains a copy of the blockchain and participates in the process of validating and relaying transactions.
Each node in the network ensures that the blockchain remains accurate and secure by cross-checking data and maintaining a shared ledger.
Nowadays you’ll see more and more of the term DePIN (Decentralized Physical Infrastructure Network, which accurately labels the way that nodes contribute physical computing power to a decentralized network in web3.
Nodes are crucial to the functioning of decentralized networks. Unlike traditional centralized systems where a single entity controls data and operations, decentralized networks distribute these tasks across multiple nodes. This distribution enhances security, reduces the risk of data tampering, and increases the network’s robustness against failures.
In simple terms, if you imagine a network as a city, nodes are like independent businesses that all agree on the same rules and work together to keep the city’s economy running smoothly. Without the effectiveness of these companies, the city would not be able to operate smoothly and provide necessary services to its inhabitants. Additionally, the viability of the entire city does not have to rely on the viability of any one business, because all the others agree on the same rules and continue to hold up the city’s infrastructure.
Each business keeps its own records, but they all share and validate information to ensure everything is accurate and consistent. This is how blockchain nodes work together, even as their operators are most likely strangers to one another, spread throughout the world.
Centralized networks are limited by things like land, real estate, energy and human resources. The larger a company gets, the more resources it must consume in an organized manner to maintain effectiveness. Decentralized systems are more scalable because they create the opportunity for remote node operators to shoulder much of this burden.
Gala Founder’s Nodes: A Specialized Role
Gala Founder’s Nodes are a specialized type of node within the Gala ecosystem. While they do not validate blockchain transactions—a task managed by the Hyperledger Fabric protocol on which GalaChain is built—they play several critical roles in supporting the network’s infrastructure.
Functions of Gala Founder’s Nodes
Decentralized Storage and Computing Power: Founder’s Nodes provide much of the necessary storage and computing power for the Gala ecosystem. This ensures that various applications, especially in gaming and entertainment, run efficiently without relying on centralized servers.
IPFS Distributed Hash Table Routing: Founder’s Nodes are instrumental in the InterPlanetary File System (IPFS), a protocol designed for decentralized file storage. They account for a large portion of the IPFS routing footprint, making decentralized internet performance significantly more robust throughout the world.
A Huge Piece of The Decentralized Web is Powered by Gala’s Node Network
Gala Founder’s Nodes account for nearly 30% of IPFS servers and Gala is leading the charge in decentralizing the internet.https://t.co/kg4CMUVr9O
Supporting Future Workloads: The scope of responsibilities for Founder’s Nodes is expected to grow. They will soon handle additional tasks such as bridge transactions and chain security, further enhancing the network’s efficiency and capabilities.
Token Distribution and Governance
Founder’s Nodes are also integral to the Gala token ($GALA) distribution process. New $GALA enters circulation by emission to Gala Founder’s Node operators as a reward for powering the network. The total amount of distribution is determined by the difference between the token’s current total supply (in circulation) and its max total supply, allowing dynamic variation of distribution based on how much $GALA is being used and burned throughout the world.
In simpler terms, Gala Founder’s Node operators are essentially licensing their computers as employees of GalaChain, putting them to work in the background and receiving $GALA regularly in exchange for that work. This method of decentralization reduces Gala’s costs for hosting and storing content through centralized providers such as Amazon Web Services.
Moreover, operators of Founder’s Nodes participate in governance decisions through consensus voting. This democratic process allows node operators to influence significant ecosystem decisions, including the distribution of tokens and other critical changes.
Why Gala Founder’s Nodes Matter
Gala Founder’s Nodes are the backbone of the Gala ecosystem, providing decentralized infrastructure support without involving themselves in transaction validation. This specialization allows them to focus on enhancing the network’s overall functionality and security, making GalaChain a more efficient and resilient blockchain solution.
Nodes are fundamental to the web3 world, enabling the decentralized systems that underpin blockchain technology. They ensure data integrity, enhance security, and support the network’s resilience. Gala Founder’s Nodes, in particular, exemplify how specialized nodes can provide critical infrastructure support, contributing to a robust and scalable decentralized network.
Proof of Stake (PoS) is a consensus mechanism used in blockchain networks to validate transactions and create new blocks.
Unlike the Proof of Work (PoW) system, which relies on computational power to solve complex mathematical problems, PoS selects validators based on the number of tokens they hold and are willing to “stake” as collateral.
Simplifying Proof of Stake
Imagine a school raffle where students can buy tickets to win a prize. The more tickets a student buys, the higher their chances of winning. However, if a student is caught trying to cheat by using fake tickets, they lose all their tickets and are banned from future raffles. This is similar to how PoS works: the more coins you stake, the higher your chance of being selected to validate transactions, but you risk losing your stake if you act dishonestly.
One of the primary advantages of PoS over PoW is its energy efficiency. PoS does not require miners to use vast amounts of electricity to solve puzzles, making it a greener alternative. This will be explored below in greater detail.
Security and Decentralization
By requiring validators to put up their own funds, PoS aligns the interests of validators with the network’s security. This typically ensures that validators have a level of financial commitment to the blockchain proportional to the weight of their validating actions.
Validators are incentivized to act honestly because they risk losing their staked coins if they attempt to cheat the system. This mechanism helps maintain decentralization, as it lowers the barrier to entry compared to PoW systems, which often require expensive mining hardware.
Scalability
PoS systems can handle more transactions per second (TPS) compared to PoW systems. This increased scalability is crucial for the broader adoption of blockchain technology, as it allows networks to support a growing number of users and applications without compromising performance. Proof of Stake is the main reason that newer blockchains than Bitcoin have been able to implement a transactional approach for a wider variety of activities. When more transactions are possible, the blockchain can be used as more than a simple ledger that keeps track of token transfers.
In PoS, validators are chosen to create new blocks based on the number of coins they have staked. To become a validator, one must lock up a certain amount of cryptocurrency in the network. This locked-up amount is known as the “stake,” and the action of locking these tokens is generally referred to as “staking.”
Validator Selection
In a typical Proof of Stake system, validators are selected randomly, but the likelihood of being chosen is proportional to the amount of stake they hold. This process is often compared to a lottery, where each coin staked acts like a lottery ticket—the more tickets you have, the higher your chances of winning.
Once chosen, a validator checks the transactions within a block to ensure they are legitimate. Once the validator correctly validates the block they receive a reward, usually in the form of additional cryptocurrency. If they validate a fraudulent transaction, they lose a portion of their staked coins, a process known as “slashing.”
Consensus
Other validators in the network then verify the block. If most agree that the block is valid, it is added to the blockchain. This collective verification process ensures the integrity and security of the blockchain.
Advantages of Proof of Stake
Reduced Centralization
PoS reduces the risk of centralization found in PoW systems, where mining power can become concentrated in the hands of a few entities with the most powerful hardware. In PoS, even those with smaller amounts of cryptocurrency can participate in the validation process, promoting a more distributed network.
Lower Barriers to Entry
Becoming a validator in a PoS system typically requires less initial investment compared to the hardware and energy costs associated with PoW mining. This accessibility encourages more participants, enhancing the network’s decentralization.
Economic Incentives
Validators earn rewards in the form of transaction fees and newly minted coins. This economic incentive aligns validators’ interests with the health and security of the network, as they have a financial stake in its success.
The Energy Efficiency of Proof of Stake
Why Proof of Work is Energy-Intensive
Proof of Work (PoW) requires miners to solve complex mathematical puzzles to validate transactions and create new blocks. This process, known as mining, involves a significant amount of computational power. As miners compete to solve these puzzles, they use large amounts of electricity to power their specialized hardware, leading to substantial energy consumption. This is particularly true for major cryptocurrencies like Bitcoin, where the difficulty of these puzzles increases over time, demanding even more computational resources and energy.
Proof of Stake (PoS) eliminates the need for energy-intensive mining. Instead of solving complex puzzles, validators are selected based on the number of coins they hold and are willing to stake. This selection process requires minimal computational power. Here’s why PoS is more energy-efficient:
No Complex Calculations: PoS does not rely on solving complex puzzles, which are the primary driver of high energy consumption in PoW systems.
Reduced Hardware Requirements: PoS validators do not need powerful, energy-hungry hardware to participate in the network. Standard computers can serve as validators, significantly lowering energy usage.
Fixed Energy Use: The energy consumption in a PoS system is relatively constant and low, regardless of the number of validators, as it primarily involves basic computational tasks rather than intensive calculations.
Scalability: PoS systems can scale more efficiently than PoW systems. As the network grows, adding more validators does not proportionally increase energy consumption.
On GalaChain
GalaChain is built on Hyperledger Fabric, using a hybrid consensus model which includes Proof of Stake.
To learn more about how GalaChain is built or to explore the possibility of developing a project of your own on this speedy, scalable and secure L1 blockchain, check out GalaChain’s SDK or apply as a Creator at the Gala Creators Portal.
Real-World Impact
The transition from PoW to PoS can lead to a dramatic reduction in the energy footprint of blockchain networks. For example, Ethereum’s shift to PoS with its Ethereum 2.0 upgrade is expected to reduce the network’s energy consumption by over 99%. This makes PoS a more sustainable and environmentally friendly option, aligning with global efforts to reduce carbon emissions and promote green technologies.
Proof of Stake represents a significant evolution in blockchain technology, offering solutions to many of the challenges faced by Proof of Work. Its energy efficiency, scalability, and economic incentives make it a compelling choice for new blockchain projects. As the web3 ecosystem continues to grow, PoS will likely play a crucial role in ensuring secure, efficient, and decentralized networks.
Imagine you’re digging for gold. You have your shovel, a lot of patience and the hope of striking it rich. Cryptocurrency mining is somewhat similar, but instead of using physical tools to dig in the ground, you’re using a computer to solve complex mathematical problems.
What is Cryptocurrency Mining?
Mining is the process through which new cryptocurrency coins are created and transactions are verified and added to a blockchain. The most well-known example of this process is Bitcoin mining. Just as gold miners invest time and resources to extract precious metals, cryptocurrency miners invest computing power and electricity to discover new coins.
How Does Cryptocurrency Mining Work?
The Basics
Cryptocurrency mining typically involves solving cryptographic puzzles. These puzzles are complex mathematical equations that require significant computational power to solve. When a miner successfully solves a puzzle, they can add a block of transactions to the blockchain and are rewarded with new coins. This process is known as “proof of work” (PoW). Once it can be proven that a miner has done the work, the tokens are effectively “mined.”
Transaction Verification: When someone sends a cryptocurrency transaction, it needs to be verified to ensure that the sender has enough funds and is authorized to send them.
Block Creation: Verified transactions are grouped together into a block.
Puzzle Solving: Miners compete to solve a cryptographic puzzle associated with the block. This puzzle is hard to solve but easy to verify once solved.
Block Addition: The first miner to solve the puzzle gets to add the block to the blockchain and is rewarded with new coins.
Reward Distribution: The miner receives a reward, typically in the form of newly minted cryptocurrency and transaction fees.
Why is Mining Important?
Mining plays a crucial role in maintaining and securing the blockchain network. It ensures that all transactions are legitimate and prevents double-spending. By requiring miners to solve complex puzzles, the network remains decentralized and resistant to attacks. This decentralized nature is a core principle of cryptocurrencies, promoting security and trust without relying on a central authority.
Different Methods of Cryptocurrency Mining
CPU Mining: This was the original method of mining Bitcoin, using a computer’s central processing unit (CPU). However, it’s no longer effective due to the high difficulty of mining puzzles.
GPU Mining: Graphics processing units (GPUs) offer more computational power than CPUs and are more effective for mining.
ASIC Mining: Application-specific integrated circuits (ASICs) are specialized devices built specifically for mining cryptocurrencies. They are the most powerful and efficient miners but are also expensive.
Cloud Mining: This allows individuals to rent mining hardware from a provider. It’s a way to mine cryptocurrencies without having to buy and maintain mining equipment.
Energy Conversion: Turning Electricity into Digital Gold
Mining is essentially the conversion of energy into digital value. Miners use electricity to power their hardware, which performs the complex calculations needed to mine cryptocurrencies. This process consumes a significant amount of energy, leading to debates about the environmental impact of mining. However, the energy used also serves to secure the network and verify transactions, making it an integral part of the blockchain ecosystem.
Mining on GalaChain: Rewarding Founder’s Nodes
In the Gala ecosystem, the equivalent to mining is the operation of Founder’s Nodes. These nodes provide the computational power necessary to maintain the decentralized network and are rewarded with $GALA tokens. Founder’s Node operators play a crucial role in supporting GalaChain’s infrastructure, similar to how miners support the Bitcoin network.
How Founder’s Nodes Work
Computational Contribution: Node operators contribute their computing power to support the network.
Reward Mechanism: In return for their contribution, operators are rewarded with $GALA tokens.
Decentralization: This system helps maintain the decentralized nature of the Gala ecosystem, ensuring that no single entity has control over the network.

Proof-of-Work (PoW) is a consensus mechanism used in blockchain networks to validate transactions and secure the network.
Proof-of-Work (PoW) was the pioneering consensus mechanism that laid the groundwork for blockchain technology. It has since been joined by several other alternatives, each with its own strengths and weaknesses. Several of these alternatives will be explored below.
It is the method by which network participants, known as miners, solve complex mathematical problems to add new blocks of transactions to the blockchain. Think of it as a competitive puzzle-solving race where the first participant to solve the puzzle gets to add the next block to the blockchain and is rewarded for their effort.
Gold Fever
Bitcoin has often been referred to as “digital gold” for several reasons: First, it has a finite total supply, just like gold buried within the rocks of the earth. Next, it acts as a store of value in the same way as gold, providing an alternative way to hold wealth to the world’s Fiat* currencies.
* “Fiat currency” is derived from the Latin “fiat,” which means a determination by an authority, or an arbitrary order. Basically, Fiat currencies are those decided upon and approved by governmental authorities… they have value because an authority told us they do.
Finally, Bitcoin resembles gold because it must be mined, converting time and energy into the retrieval of BTC for miners. In the same way, gold miners must commit financial resources, time and energy into their operations. A miner who only expects to find a few specks of gold can probably do so in a wise location with only simple panning equipment, but a large company with employees and equipment expenses needs to mine a great deal more gold to prove a profitable venture.
How Does Proof-of-Work Work?
Transaction Bundling: When users initiate transactions, these are grouped together into a block by miners.
Puzzle Solving: Miners compete to solve a cryptographic puzzle, which involves finding a hash (a fixed-length string of characters) that meets specific criteria. This process is computationally intensive and requires significant processing power. Most of these computations are executed by GPUs (Graphics Processing Unit) because of their ability to quickly perform extremely complex calculations.
Block Validation: The first miner to solve the puzzle broadcasts their solution to the network, which is then verified by other miners. If the solution is correct, the block is added to the blockchain.
Reward: The miner who successfully adds the block is rewarded with newly created cryptocurrency and any transaction fees from the transactions included in the block.
Security: PoW secures the blockchain by making it computationally expensive to alter any part of the blockchain. To change a block, an attacker would need to redo the PoW for that block and all subsequent blocks, requiring immense computational power.
Decentralization: PoW allows a decentralized network of miners to compete to validate transactions, reducing the risk of central control.
Integrity: It ensures that all transactions are processed in a trustless manner, meaning participants do not need to trust a central authority but can trust the network’s consensus rules.
“Consensus” in web3 – An agreement between all participants in a blockchain network on the order and content of blockchain blocks.
Proof-of-Work Simplified
Imagine a large-scale Sudoku competition where participants race to solve the puzzle. The first one to complete it correctly gets a prize and publishes their solution, which others can quickly verify as correct or incorrect.
Think of the PoW puzzle as a lock and the solution as the key. Each miner tries different keys (hash values) until one fits (meets the criteria). The first one to unlock the lock (solve the puzzle) can add a new block to the blockchain and collect its associated rewards.
Energy Consumption: PoW requires significant computational power, which translates to high energy consumption, raising a plethora of environmental concerns. This concern has been the primary driver of development of alternative consensus mechanisms in web3.
Centralization Risks: Despite being a decentralized mechanism, PoW can lead to centralization of mining power in regions with cheap electricity or in the hands of entities that can afford specialized hardware. Some people worry that mining operations will become overly centralized with this approach, especially if reward value continues to increase at a level that will justify large scale operations and great expense.
Scalability Issues: PoW networks, like Bitcoin, face scalability challenges due to the time and resources required to solve the cryptographic puzzles and add new blocks.
Alternatives to Proof-of-Work
In response to these challenges, alternative consensus mechanisms have been developed, such as Proof-of-Stake (PoS), which relies on validators who stake their cryptocurrency to propose and validate blocks, requiring less computational power.
Proof-of-Stake (PoS)
The main alternative to Proo-of-Work is Proof-of-Stake, in which Validators stake their cryptocurrency to participate in the network. They are selected to create new blocks based on the amount of staked cryptocurrency.
Strengths
Energy-efficient: Significantly less energy consumption compared to PoW.
Faster transaction times: Can process transactions more quickly.
Weaknesses
Potential for centralization: Wealthier validators can have greater influence.
Security risks: Vulnerable to attacks like the “nothing-at-stake” problem (when the cost to create blocks becomes too low).
With this mechanism, token holders vote for delegates who validate blocks. With fast transaction times, this method closely resembles PoS but with increased scalability. However, decentralization is reduced because more staking power can be concentrated in the hands of fewer delegates. Plus, if delegates are compromised for any reason, things can go awry for the chain.
Other Consensus Mechanisms
Proof-of-Authority (PoA): Relies on a pre-selected group of validators to validate transactions.
Proof-of-Burn (PoB): Requires users to destroy cryptocurrency to become a validator.
Proof-of-Capacity (PoC): Uses hard drive space as a measure of stake.
Proof of Storage (PoS): Validators prove they are storing data to secure the network and earn rewards.
GalaChain is a highly advanced blockchain, first built by our web3 experts to accommodate the rapidly expanding and evolving needs of gaming and entertainment.
It uses a special hybrid model of pluggable blockchain consensus. GalaChain was built on the Hyperledger Fabric protocol, which allows consensus to be highly customizable on individual channels. An Ordering Service works with predesignated peers on the network to sign transactions in a multi-step, asynchronous system.
Despite its criticisms, PoW remains a foundational technology in the blockchain space, particularly for major cryptocurrencies like Bitcoin. Innovations and improvements in mining technology and energy efficiency are being explored to mitigate its environmental impact. Even as other consensus mechanisms are introduced, Proof-of-Work elements will still be used in a growing variety of hybrid consensus models.
Even if Proof-of-Work is gradually phased out of prominence as a consensus mechanism, it will continue to work well as an educational basis to help anyone understand the decentralized nature of blockchains and cryptocurrencies.
Proof-of-Work is a vital component of many blockchain networks, providing security, decentralization and integrity. Understanding PoW is essential for grasping how blockchain technology works and its implications for the future of digital transactions and decentralized systems.
In the simplest terms, a web3 wallet is your digital wallet for the decentralized web. Think of it as a special app that lets you store, send, receive, and manage your cryptocurrencies and digital assets. But it does more than just hold your “money.” A web3 wallet can interact with decentralized blockchain applications (dApps), making it a crucial tool for navigating the web3 world.
Typically, a person will only have a single IRL wallet, holding important items like driver’s licenses, credit cards and maybe some cash. One notable difference with web3 wallets is that it’s rather common to have more than one. For people dabbling in cryptocurrency through a mainstream exchange such as Coinbase, they may look no further than their Coinbase wallet, which will include all the functions they’ll need to trade and own on that platform. However, once users are interested in exploring new platforms and different blockchain ecosystems, they’ll quickly find that a new wallet will often optimize organization and convenience.
Wallets on GalaChain
Gala’s wallet approach is fairly simple due to the fact that GalaChain was built for the Gala ecosystem. Therefore, your GalaChain wallet is connected to your free Gala account. Having a wallet on GalaChain is as simple as having a Gala account.
Please note that while your GalaChain wallet is closely connected to your GalaChain account, it is yours and yours alone. Gala is a non-custodial wallet, meaning that it does not have access to your wallet or its private keys.
Tokens on GalaChain are built to interoperate with Ethereum, allowing you to bridge NFTs, crypto and in-game items to and from the Ethereum blockchain with ease. This is also accomplished by integrating one of the supported Ethereum-based web3 wallets with your Gala account. This connection can be made in your account’s Settings menu. For a quick guide on how to make this connection, check out this support article.
Our recommended external web3 wallet for the Ethereum blockchain is Metamask, the most widely used and trusted web3 wallet software in the world today.
Why Are Web3 Wallets Important?
Web3 wallets are essential for several reasons to anyone looking to experience the full range of opportunities and interactions available in web3:
Ownership and Control: Unlike traditional banking, where a third party holds your funds, web3 wallets give you full control over your assets. You own your private keys, which means you have complete control over your funds and transactions.
Security: Web3 wallets use advanced cryptography to secure your assets. As long as you keep your private keys safe, your funds are secure.
Decentralized Access: Web3 wallets allow you to interact with decentralized applications without needing to create multiple accounts. This is akin to having a universal login for all dApps, making the user experience seamless and efficient.
Innovation and Flexibility: With web3 wallets, you can participate in new financial systems, like DeFi (Decentralized Finance), and access unique digital assets like NFTs (Non-Fungible Tokens).
How Do Web3 Wallets Work?
Public and Private Keys
At the heart of every web3 wallet are two types of keys: Public and private keys. These keys are not literal keys, but strings of cryptographic codes that play different roles:
A Public Key is like your bank account number. It can be safely shared with others and used to receive funds.
A Private Key is like your PIN or password. It’s used to sign transactions and access your funds. Keeping this key secure is critical because anyone with your private key can control your wallet.
There are several types of web3 wallets, each offering different features and levels of security:
Software Wallets are applications or browser extensions, like MetaMask, that you can install on your computer or smartphone. They are convenient and easy to use but can be vulnerable to malware and phishing attacks. This is why it’s important to lock or log out of your software wallet when not in use.
Hardware Wallets: These are physical devices, like Ledger or Trezor, that store your private keys offline. They offer enhanced security by keeping your keys away from internet-connected devices, making them immune to online attacks.
Paper Wallets: These are simply printouts of your public and private keys. While they can be very secure (if stored safely), they are not practical for everyday use and can be easily lost or damaged.
Custodial Wallets: These wallets are managed by a third party, like an exchange, which holds your private keys for you. While they offer convenience and easy access, they also require you to trust the third party with your assets.
In the Gala ecosystem, as described in the Gala Ecosystem Blueprint, wallets play a pivotal role. GalaChain, the purpose-built blockchain for the Gala Games, Film and Music ecosystems, integrates with web3 wallets to provide users with seamless access to their digital assets and interactions within Gala dApps. Whether it’s buying in-game assets, participating in community votes, or collecting rewards through node operations, a web3 wallet is your gateway to these activities.
