Secure Crypto

23 Dec 2023

Welcome to the exciting world of cryptocurrency! In this guide, you're about to embark on a journey through the basics of crypto – what it is, how it works, and most importantly, how to secure crypto. Whether you're new to digital currencies or looking to strengthen your existing knowledge, this guide is designed to provide clear, easy-to-understand insights. By the end, you'll not only grasp the fundamental concepts of cryptocurrencies like Bitcoin and Ethereum, but you'll also be equipped with essential strategies to secure your crypto assets. So, let's dive in and learn everything you need to know about crypto.

The private key

In the world of cryptocurrency, a private key is the only thing that matters. It’s how you secure crypto and NFTs. Imagine your crypto wallet is a special kind of digital bank account. The private key is a unique and very long set of numbers and letters that only you should know. The most important password you will ever have. It's the key to your digital treasure chest. When you want to send or receive cryptocurrency, like Bitcoin, you use this private key. It proves that you are the owner of the crypto without revealing your secret key to anyone else. If someone else gets your private key, it's like they have the key to your treasure chest, so it's super important to keep it safe and never share it with anyone. This is how your cryptocurrency stays secure – only you have the key to access and use it.

The address

The next thing you need to know is the crypto address. An address is a critical component that plays a central role in transactions. Think of a crypto address as a public mailbox where you receive your digital currency. This address is derived from your wallet's public key, which is itself generated from your private key (the secret password we talked about earlier). Unlike the private key, the public key, and hence your address, is meant to be shared with others. It's like an email address for your crypto wallet, allowing others to send you cryptocurrency. Each time you initiate a transaction, such as receiving Bitcoin, you share this address. It’s a long string of letters and numbers, unique to your wallet, and acts as a secure destination for your digital funds. 

Importantly, while your address is visible to others in the blockchain network when you receive transactions, it doesn't reveal your identity or the specifics of your wallet's contents. This balances transparency in the crypto network with personal security, ensuring that while transactions are verifiable and traceable, your personal information and the access to your funds remain protected. 

The owner

When it comes to cryptocurrencies, understanding ownership is key. Unlike traditional money that you can hold in your hand, crypto ownership is established digitally. It's all about who holds the keys. Here's how it works: a cryptocurrency, like Bitcoin, is owned by an address, which we just learned about. This address is linked to a public key, and behind that public key is a private key - the one that only you should know. When you have a cryptocurrency in your wallet, what you actually own is a record on the blockchain (a kind of digital ledger) that says, "This amount of crypto belongs to this address." As long as you control the private key associated with that address, you control the cryptocurrency linked to it. No one can move or use that crypto without the private key. It's like having a safe deposit box where the box is the address, the contents are your crypto, and the key to open the box is your private key. This setup ensures that you have full control over your digital assets. So, in the crypto world, ownership isn't about physical possession; it's about having the exclusive rights and ability to access and transfer your digital assets through your unique keys.

The blockchain

At the heart of cryptocurrency is the blockchain, a powerful technology that documents ownership and ensures secure transfers. Imagine the blockchain as a digital ledger or a record-keeping book that's open for everyone to see. Every time someone transfers cryptocurrency, like sending Bitcoin to a friend, this transaction is recorded on the blockchain.

Here's how it works: When you transfer crypto, the transaction is grouped with others into a 'block' of data. Each block contains a list of recent transactions. But before a block is added to the blockchain, it must be verified and secured. This is where the unique feature of the blockchain comes in – each new block is connected to all the previous ones, forming a chain. This connection is made possible with complex mathematics that you don’t need to understand, but know that it makes sure that transactions are finalized and secured forever once added to the blockchain.

The chaining of blocks ensures that every transaction is permanent and transparent. Once a block is added to the chain, the transaction is complete, and the ownership of the cryptocurrency changes accordingly. The recipient's address now shows a record of receiving that crypto, and the sender's address shows a record of sending it. This process guarantees that the history of every crypto transaction is recorded and that ownership is clearly and publicly documented on the blockchain.

The beauty of the blockchain is its transparency and security. Since every transaction is publicly recorded and linked to previous transactions, it's nearly impossible to fake a transaction or alter the history of a transaction. This makes the blockchain a trustworthy and essential Concept Number of how cryptocurrencies work. So, in the world of crypto, the blockchain doesn't just record transactions; it's the backbone that ensures the integrity and security of digital currency ownership and transfers.

The miner

Mining is a strange concept that you need to understand. It serves as the backbone for generating new blocks on the blockchain. But why does mining exist, and how does it drive the economics of a coin like Bitcoin? Let's break it down.

Mining is essentially the process of creating new blocks to add to the blockchain. When miners mine, they use powerful computers to solve complex mathematical problems. These problems are so challenging that they require significant computational power to solve. The first miner to solve the problem gets the right to add a new block of transactions to the blockchain. This process is crucial because it's how everything is kept in line.

But mining isn't just about maintaining the blockchain; it's also how new coins are created. When a miner successfully adds a block to the blockchain, they are rewarded with a certain number of new coins. This reward is an incentive for miners to keep the blockchain running smoothly. The creation of new coins through mining is how cryptocurrencies like Bitcoin inject new units into circulation, which is a critical aspect of their economics.

Moreover, mining affects the supply of the coin. For instance, in Bitcoin's case, there's a cap on the total number of coins that will ever exist - 21 million. The rate at which new coins are created slows down over time in an event known as halving, which happens every four years. The next halving will happen in April 2024. This limited supply and decreasing rate of new coin creation help to drive the value and demand for the coin.

In essence, mining is not just a technical process but a critical economic activity. It secures the blockchain, facilitates the processing of transactions, and governs the issuance of new coins, all of which are key to the functioning and value of cryptocurrencies. Through mining, cryptocurrencies can maintain a decentralized, secure, and economically viable system.

The seed phrase

The "seed phrase" is a crucial concept in cryptocurrency. It is the tool that helps you recover your private key if you lose it. Typically, a seed phrase is a series of 12 to 24 words generated by your crypto wallet when you first set it up. It's an essential backup tool for accessing your cryptocurrencies, and you better be sure to keep it safe.

Here's why it's so important: If you lose access to your crypto wallet - maybe your phone gets lost, your computer crashes, or you forget your wallet password - the seed phrase is your recovery tool. By entering these words into a new instance of your wallet, you can regain access to all your cryptocurrencies. It's like having a backup key to every lock in your house.

The words in a seed phrase aren't random; they're taken from a specific list known as a wordlist and are generated in a particular order. This order is crucial - even if you have the correct words but in the wrong order, you won't be able to recover your wallet.

It's vital to keep your seed phrase extremely secure and private. If someone else gets hold of it, they can access your wallet and steal your cryptocurrencies. Writing it down and storing it in a safe place, away from prying eyes and potential digital theft, is a good practice. Never store it on an internet-connected device or share it with anyone.

In summary, a seed phrase is a powerful tool in the cryptocurrency world but also a dangerous point of failure. To properly secure crypto, you need to ensure that your seed phrase is safe. 

Now that you understand the main concepts in blockchain technology, including the critical roles of private keys, addresses, ownership, the blockchain itself, and mining, it's time to focus on the core intention of this blog post: how to secure your crypto assets. Security in the world of cryptocurrency is not just a feature—it's an essential practice that underpins every interaction you have with digital currencies. With the foundational knowledge you've gained about how cryptocurrencies operate, you're now in a great position to explore the various strategies and tools available to safeguard your digital investments. Whether you're a casual user, an avid trader, or someone interested in the broader implications of blockchain technology, understanding and implementing robust security measures is crucial for protecting your assets in this dynamic and evolving digital landscape. Let's delve into the practical steps you can take to ensure your crypto journey is not only exciting but also secure.


Traditional way to secure crypto

Securing your cryptocurrency using the traditional seed phrase backup tools involves a few critical steps to ensure utmost safety. First and foremost, when you create your crypto wallet, it will generate a seed phrase, usually a series of 12 to 24 words. Treat this seed phrase with the highest level of security—it's the master key to your digital funds. Write down the seed phrase on paper and avoid digital copies to reduce the risk of online theft. Store this paper in a secure location, such as a safe or a locked drawer. Some people go a step further by using a metal seed storage tool, which protects the phrase from physical damage like fire or water. It’s also wise to have multiple copies stored in different secure locations, in case one is lost or damaged. Remember, anyone who gains access to your seed phrase can access your crypto assets, so discretion is crucial. Don’t share it with anyone, and be wary of phishing scams or fraudulent services asking for your seed phrase. By meticulously safeguarding your seed phrase, you create a robust line of defense for your crypto assets, ensuring that you can always regain access to your wallet, even if the device you use for transactions is lost or compromised.

New way to secure crypto

If you think traditional backup methods are painful, then you are not alone. Thankfully, the landscape of crypto security is evolving with the advent of new technologies like MPC (Multi-Party Computation) and distributed storage. This innovative approach is changing how we secure our digital assets, making the traditional seed phrase a thing of the past. By eliminating this single point of failure, these new methods significantly enhance security. With the use of MPC, the responsibility of key management is distributed among multiple parties. This means no single entity has complete access to your key, drastically reducing the risk of total loss or theft. Additionally, distributed storage scatters pieces of your key across various locations, adding layers of security and simplifying recovery processes. A notable application of this technology is found in platforms like Gridlock, which not only employ these advanced methods but also introduce features like social verification. This unique aspect allows a network of trusted individuals to assist in securing and recovering each other's crypto assets, blending state-of-the-art technology with the power of community collaboration. The result is a more resilient, user-friendly approach to safeguarding your cryptocurrencies.

To wrap it up, gone are the days of relying solely on traditional methods like seed phrases. The future is here with groundbreaking technologies like MPC and distributed storage, revolutionizing how we safeguard our digital treasures. Embracing these innovations means not just enhanced security but also the power of community-driven safeguards through social verification. In the ever-evolving universe of cryptocurrency, staying ahead in security isn’t just smart; it's essential. Secure your crypto, secure your future!
