6 min readSep 28, 2023


In the digital era, the significance of user privacy and security cannot be understated. As technology evolves, so do the challenges and threats to individual privacy and data security. This becomes even more pertinent when dealing with financial assets, particularly in the ever-expanding cryptocurrency industry.


When you exchange crypto or buy crypto, the need for robust and reliable security measures is paramount. Among the leading players in the cryptocurrency industry, FIRO and NOW Solutions stand out for their unwavering commitment to user privacy and security.

FIRO and NOW Solutions: Champions of Privacy and Security

FIRO and NOW Solutions are dynamic entities in the cryptocurrency sector. They have made their mark by offering cutting-edge solutions that safeguard user privacy and security while providing a seamless crypto exchange experience. The significance of user security in the context of cryptocurrencies has been a driving force behind their innovative solutions. They understand that as cryptocurrency adoption grows, so does the risk of security breaches and privacy infringement. Hence, they have made it their mission to provide platforms where users can buy crypto, exchange crypto, or simply manage their digital assets with the utmost confidence in their security.

FIRO: A Privacy-centric Approach to Cryptocurrency

FIRO, formerly known as ZCoin, is a privacy-focused cryptocurrency that offers its users a secure environment to manage their digital assets. Built on a mission to enhance privacy and security in the digital realm, FIRO leverages advanced cryptographic techniques to ensure that your transactions remain completely private. Unlike traditional cryptocurrencies, which leave a trail of transaction history on the blockchain, FIRO breaks the link between the sender and receiver, offering robust privacy to its users.

ChangeNOW and NOWPayments: Secure Crypto Solutions

ChangeNOW and NOWPayments, is well-known user-friendly and secure platforms that facilitate crypto exchange and payments. With ChangeNOW, users can swiftly exchange crypto without having to worry about custody issues or complex procedures. On the other hand, NOWPayments is a cryptocurrency payment gateway that enables businesses to accept crypto payments for their products and services, enhancing payment flexibility while maintaining high security standards.

FIRO’s Expert Solutions for User Security

FIRO’s commitment to user security and privacy is manifested in its innovative privacy protocols and robust security measures. One of the most notable features is the Lelantus Spark, a groundbreaking privacy protocol that addresses the fundamental challenges of privacy and confidentiality in the digital realm.

Lelantus Spark: The Privacy Game-Changer

Lelantus Spark, a revolutionary protocol developed by the FIRO team, offers a comprehensive solution to the issues of transaction privacy and traceability. Utilizing a burn and redeem model, it ensures that coins are anonymized during the burn process and later redeemed as fresh coins with no transaction history. This means that transactional information, including the sender, receiver, and the amount, remains completely hidden from prying eyes. Lelantus Spark provides several key advantages that set it apart from other privacy protocols. It eliminates the need for a trusted setup, ensuring a higher level of security and trustlessness. Additionally, its modular design and reliance on well-established cryptographic assumptions make it efficient and resistant to attacks.

Zero-knowledge Proofs and Chainlocks

To enhance the overall security of the FIRO network, the platform has implemented zero-knowledge proofs through the Lelantus protocol and Chainlocks. Chainlocks is a consensus mechanism utilized by Firo that combines the power of masternodes and the decentralized nature of the network to provide fast and secure transaction confirmations, preventing double-spending and ensuring the integrity of the blockchain. These measures provide trustless privacy and a higher level of anonymity, ensuring transaction details remain private.

Secure Mining Algorithm

FIRO uses FiroPoW, a memory-intensive Proof-of-Work mining algorithm, which deters the use of Application-specific Integrated Circuits (ASICs) in mining. This promotes a more egalitarian mining process, allowing ordinary users to mine FIRO using their GPUs.

Expert Tips: How to Stay Secure in the Crypto World

While platforms like FIRO and NOW Solutions provide robust security measures, users also need to play their part in safeguarding their digital assets. Here are some expert tips on how to enhance your security in the crypto world:

  • Choose the Best Crypto Wallet: Selecting a secure crypto wallet, such as NOW Wallet, is essential for the security of your digital assets.
  • Use Strong and Unique Passwords: Avoid using easily guessable information for your passwords and consider using a password manager. Password managers can generate strong, complex passwords consisting of a combination of letters, numbers, and special characters. These passwords are typically much more secure than those we tend to create ourselves
  • Enable Two-Factor Authentication (2FA): This adds an extra layer of security to your accounts. This can be a unique code generated by an authentication app on your smartphone, a text message with a verification code, or the use of a physical security key that needs to be inserted into your device
  • Keep Your Private Keys Secure: Never share your private keys with anyone and store them securely. You can use encrypted storage methods, such as encrypted USB drives or paper wallets, to store your private key. These methods allow you to keep your key offline and protect it from digital threats.
  • Regularly Update Your Wallet Software: This ensures that you’re using the latest security features and patches. Wallet software developers often release updates that include bug fixes, performance improvements, and most importantly, security patches. By keeping your wallet software up to date, you ensure that you are benefiting from the latest security features and enhancements, reducing the risk of potential vulnerabilities.
  • Be Aware of Scams and Phishing Attempts: Always double-check URLs and verify the authenticity of any software downloads or communication you receive.
  • Use Cold Storage for Large Holdings: Only keep a small amount of crypto in online wallets or exchanges that you’re willing to risk losing. For large holdings that you don’t need immediate access to, it is recommended to keep them in cold storage solutions such as hardware wallets, paper wallets, or offline storage devices. These methods ensure that your private keys, which grant access to your funds, are kept offline and away from potential online threats.
  • Regularly Backup Your Wallet: Store the backup in a secure location regularly. Wallet backups serve as a safeguard against various potential risks such as device failure, accidental deletion, or loss of access to your wallet.
  • Educate Yourself on Best Practices: Stay informed about the latest security trends in the crypto world. The crypto world is constantly evolving, and new security threats and vulnerabilities emerge regularly. By staying informed about the latest security trends and news, you can proactively protect yourself from potential risks.
  • Be Mindful of Your Online Presence: Be careful about sharing information about your crypto holdings or activities. In the digital age, it’s important to be cautious about sharing personal information that could potentially expose your crypto holdings to malicious individuals or increase the risk of targeted attacks. You can trust no one besides yourself.
