3 Key Technologies Behind Web3 Shaping Our Digital Future

Key Technologies Web3

The internet as we know it is transitioning from Web2 to Web3. This shift marks an important moment in its evolution, as it greatly benefits users globally. One of the main benefits is the transfer of power from centralized entities to decentralized ecosystems where users are in control. This changes the way we interact online by offering enhanced levels of security, privacy, and autonomy.

While we are at the edge of this transition, it is important to understand the core things that make Web3 possible. These technologies are the foundation for a new digital era that will transform communications, transactions, and online interactions.

This article explores the core technologies that power this new age of the Internet, including blockchain, cryptography, decentralized networks to see how they contribute to the functioning of the decentralized web. There are more technologies powering Web3 but we want to specifically focus on these three for now.

The Infrastructure of Web3

Web3 infrastructure is made up of three technologies: blockchain, Cryptography, and Decentralized Networks, all of which play important roles in bringing the digital age to life and helping users interact with enhanced security, autonomy, and efficiency. Together, these three technologies (blockchain, cryptography, and decentralized protocols) form the backbone of Web3, promising an internet that returns control to the users.

Blockchain Technology: Web3’s Backbone

It wouldn’t be an exaggeration to say that Web3 wouldn’t be possible without blockchain. Often referred to as the cornerstone of Web3, blockchain is a distributed ledger that contains a record of transactions across a network of computers rather than sticking to one centralized server. For users, this guarantees that the information in the database can’t be changed, and thus can be trusted by all parties.

For this reason, it’s possible to maintain Web3’s decentralized network 

Here’s an exploration of why blockchain is fundamental to the functioning of Web3:

  • Decentralization: As discussed, blockchain works without any central authority, with every node within the network able to participate. The decentralization of the data is the most fundamental aspect of Web3.
  • Transparency: Web3 is a trustless environment. Blockchain removes the need for trust, as all the transactions recorded on the blockchain are public and visible to all participants. 
  • Immutability: Once a transaction is recorded on a blockchain, it cannot be changed. For users, this means that transactions can be carried out without fear of the records being changed fraudulently. This is a useful feature for Web3 apps (or dApps) that require transparent transaction histories, identity verification, voting systems, etc. 
  • Smart Contracts: Blockchain enables the deployment of smart contracts, which execute automatically once the agreement rules are met. These are essential for the decentralized web to function independently.
  • Tokenization: One of the popular applications of blockchain technology is cryptocurrency and asset tokenization. With it, real-world assets can be transformed into digital tokens, opening up possibilities for ownership, trade, and investment in the Web3 world.
  • Interoperability: Blockchain’s interoperability allows different networks to communicate and share information seamlessly. 

Cryptography: The Security Layer

Cryptography is the essential security layer behind Web3. It’s made up of complex mathematical algorithms that protect data and ensure that it can be safely shared over the network. Cryptographic techniques like public-key cryptography and hashing protect users’ identities and the integrity of transactions. With cryptography, no one except the intended recipients can decrypt and access the information sent, thereby safeguarding against unauthorized access and tampering.

Here’s a detailed look at why cryptography is important for Web3:

  • Data Security: It is essential because it locks down our digital info on Web3, much like a vault. This way, hackers are kept out, and only those meant to see the data can get access to it.
  • Identity Verification: This property is key to Web3 as it lets us prove who we are on the decentralized web securely without oversharing personal details.
  • Trustless Transactions: Cryptography is what makes trustless transactions possible- safely carrying out dealings directly with a third party without a third party intermediary, such as a Central Bank. 
  • Public and Private Keys: They’re the core of Web3 security, acting like a secure mailbox for our digital assets that only we have the key to open, safeguarding ownership and transactions.
  • Secure Communication Channels: Cryptographic techniques are the key to the secure communication lines in Web3 innovations, protecting messages and transactions from being intercepted by unwanted parties.
  • Protection Against Quantum Attacks: Cryptography also helps networks more capable of resisting quantum computing attacks.

Decentralized Networks and Protocols: Facilitating a Distributed Internet

Decentralized networks and protocols are the reason we can imagine and actualize this new generation of internet- one without centralized servers, and one where the data is distributed among all the participating nodes. Because of this, it’s much harder to tamper with information. Even if there’s a network failure at a point, the effects won’t be widespread. 

These networks operate on consensus mechanisms that ensure every participant verifies new transactions before they are added to the digital ledger. For instance, protocols such as IPFS (InterPlanetary File System) aim to replace centralized web servers with a peer-to-peer network, making the web more accessible and resistant to censorship.

These are the decentralized networks’ features that are essential for Web3 to function smoothly:

  • Peer-to-Peer Architecture: This setup avoids a single point of failure by allowing everyone in the network to access data anytime, making the web more reliable and hard to shut down.
  • Enhanced Security: When it comes to data security, the wiser approach is to store it across multiple data centers rather than a centralized one. This is exactly what decentralized protocols do- making stealing or corrupting data much harder and offering a safer space for everyone’s digital lives.
  • Data Sovereignty: It’s like keeping the keys to your personal diary, ensuring only you decide who reads it. For Web3, this means users truly own their data, making personal information safer and more private.
  • Consensus Mechanisms: Consensus is akin to having a group agreement on the truth without needing a boss to decide. In Web3, they help ensure everyone plays by the rules, creating a fair and transparent environment.
  • Censorship Resistance: This feature of decentralized protocols keeps Web3 open and accessible, letting ideas flow freely without anyone controlling or restricting them.

Why do i Need a Wallet?

Freename domains are blockchain-based assets and would be minted and stored using a wallet. Users are required to mint and manage their domains using a Metamask or Coinbase-configured wallet. It must be a non-custodial wallet, meaning that one must own the private keys to the wallet in order to approve transactions via a signature.

To benefit from Freename Web 3 domains/TLDs, you must have a wallet. This is because Web 3 domains/TLDs are blockchain-based assets. Users can mint and manage their domains using Metamask or Coinbase-configured wallets.

Keep in mind that it must be a non-custodial wallet. You own the private keys to the wallet (in order to approve transactions via a signature).

Are the Domains Associated with ICANN?

ICANN does not manage freename.io domains. Freename.io believes their TLDs/domains must allow customers to operate independently. Freename.io wants to build a utility infrastructure, allowing customers to use their services for valuable and generative purposes. By leveraging blockchain technology, Freename Web 3 domains/TLDs have no centralized authority imposing rules and regulations.

What is a Wallet?

Every blockchain user requires a wallet in order to interact with the network. A wallet is essentially an account on the blockchain where transactions can be sent and received. It is also where one can store blockchain assets such as cryptocurrency or NFTs (non-fungible tokens). There is no personal information associated with a wallet and none is required to create one. A wallet consists of a public key and a private key. The public key can be safely shared with anyone who wishes to send assets to the corresponding wallet, however, the private key should not be shared and is the key to accessing the wallet in the event where access is lost or to create another instance.

A crypto wallet (cryptocurrency wallet) is software or hardware that enables users to store and use cryptocurrency. With cryptocurrencies, there isn’t any actual money to carry around in a wallet. They exist on the blockchain. Similarly to traditional bank transfers, crypto wallets enable users to send and receive cryptocurrencies, NFTs, etc.

A wallet consists of a public key and a private key. To receive assets, you share your public key associated with your wallet. You should NEVER share your private key.

Can i Transfer Domains?

Yes. The domain is stored in your cryptocurrency wallet and can be transferred by you after you have minted it. Access your portfolio, select the TLD or Domain you wish to transfer and type the recipient’s address. Afterwards, you must paste the OTP code you received by mail to confirm the transaction. Keep in mind that currently, it is not possible to import the domain that has been transferred, but it will be possible soon!

Yes. Domains are transferable ONLY after a TLD/domain has been minted and stored in a user’s wallet.

To transfer the TLD (or domain), the user must:

  • Access their wallet
  • Select the item they want to transfer
  • Enter the recipient’s address.
  • Confirm the transaction by pasting the OTP received by email

In the future, Freename.io will support importing domains that have been transferred.

What about Trademarks?

Registering a trademark on your Freename Web3 TLD will allow you to protect your web3 TLD and your logo worldwide juridically.

From the moment you deposit a trademark request, your web3 TLD will be protected worldwide for 6 months awaiting for the Swiss Federal Institute of Intellectual Property (IGE.ch) to confirm and register the availability of your TLD.****

A trademark is any symbol, phrase, or word that allows customers to identify a company’s goods or services. Freename is a web3 domain/TLD provider that also provides trademark registration.

A user must reach out to the trademark department to register a trademark. To get your trademark filed for review at the Swiss Federal Institute of Intellectual Property, a user must provide the following:

  1. Complete a Know your customer (KYC)
  2. A list of TLDs they wish to trademark
  3. Proof of payment

Once these conditions are met, it takes one week for the trademark to be reviewed and logo/TLDs to be provided with six months of worldwide protection.

Is Minting the same as Buying?

Purchasing a TLD (or domain) on Freename and minting it on the blockchain are two distinct steps. When you purchase a TLD (or domain), the transaction is recorded in Freename’s database and not on the blockchain. Minting a TLD (or domain) on the blockchain requires a second step: log into the user’s personal area, select the TLD (or domain) and press “mint TLD” (or domain): done! Don’t worry, once you have purchased a Freename domain, no one can take it away from you!

No. Buying and Minting a TLD/domain are two different things.**

Buying **is the process of recording a transaction on Freename’s database and not on the blockchain.

Minting is the process of pushing a user’s domain from Freename.io data onto the public ledger of a blockchain and into a user’s wallet. Giving the user full control over the TLD/domain.

It is very easy to mint a domain/TLD once you purchase it. Simply:

  • Log into your personal area
  • Select the TLD (or domain)
  • Press “mint TLD” (or domain)

What is Domain Minting?

Minting is the process of publishing a Freename domain (or TLD) on the blockchain via your wallet to gain full custody of the domain. This means that the only person that has control over the domain (or TLD) is the person who controls (has access to) the wallet.

Minting is the process of pushing a user’s domain from Freename.io data onto the public ledger of a blockchain and into a user’s wallet. Giving the user full ownership over the domain.

Minting on Freename.io is as simple as the following steps:

  1. Go to the Freename.io website
  2. Enter the TLD/domain you want to buy in the search bar
  3. Add the TLD/domain to your cart
  4. Go to checkout
  5. Create a Freename.io account
  6. Purchase the TLD/domain with cryptocurrency or a credit card
  7. Go to “portfolio and incomes.”
  8. Click on mint TLD/domain

Which domains are Protected?

Protected domains and TLDs are domains and TLDs that we’ve detected are associated with a brand, organization, or notable person. We believe it is important to increase adoption for the next generation of the internet by helping to onboard brands into the Web3 era. If you are interested in applying for a Protected domain, please contact us.

TLDs/Domains associated with a notable person, brand or organization are considered Protected Domains. Protected domains help onboard brands in Web 3 increasing adoption. Protected domains also protect users from others impersonating/stealing their domains.

Reach out to Freename.io to apply for a protected domain.

Why use Freename?

Freename domains are unique by their very nature: only with Freename you can register domains with unique TLDs for your digital identity while passively earning money!

Freename.io is not only the leading TLD and Domains platform in Web 3, but also lets users generate passive income!

Owning a Freename Web 3 TLD entitles users to receive passive income whenever a domain is bought on their TLD. Users can register and mint TLD/domains of their choice if available.

What is a Domain?

A domain name is a string of letters and/or numbers that points to the IP address of the corresponding website. Generally, it is easier to remember a name than a long string of numbers.

A domain name is an address that people type into a browser bar to find a website. It consists of a Top-Level Domain (TLD), everything that comes after the dot, and the Second-Level Domain (SLD), everything that comes before the dot.

For example, “Freename.io” is the domain name, “Freename” is the SLD and “io” is the TLD.

Which Chains are Supported?

Freename has a multi-chain approach. You can choose on which Blockchain to mint your Web3 Domains and TLDs ranging Among Polygon, Cronos, and Binance.

A user can mint a Freename.io domain/TLD on the following blockchains:

  • Polygon
  • Cronos
  • Binance

Freename plans to expand its multi-chain approach by adding blockchains upon which domains can be minted.

Are there Renewal Fees?

No! Once you’ve bought a Freename Domain or TLD, it’s yours forever, no renewal fees ever!

No. There are no renewal fees on Freename.io. Once a user has paid a one-time payment for a domain/TLD, they own it. Forever.

This is the significant advantage of Web 3 domain/TLD over traditional alternatives.
