🛡️ Digital Currency Security... How to protect your money in the blockchain world?
Despite the advantages of digital currencies, such as speed and decentralization, security threats remain one of the most prominent challenges. Since the launch of Bitcoin, many wallets and platforms have been hacked, leading to losses in the millions of dollars. Therefore, understanding the fundamentals of digital currency security is vital for every user or investor.


Main Risks:
Hacks: Targeting centralized or decentralized wallets, you could lose all your money within minutes.
Social Engineering: Such as phishing messages or pages that ask for your passwords or secret phrases.
Malware: Software that records user clicks or steals private keys.


Main Protection Methods:
✅ Use cold wallets: These are wallets that are not connected to the internet.
🔑 Securely store the private key: Never share it, preferably write it down and store it in an offline location.
🧩 Enable two-factor authentication (2FA): Especially on trading platforms.
🚫 Avoid suspicious links or untrusted applications.


Is blockchain secure?
Yes, technically, the blockchain itself is considered one of the most secure technologies thanks to encryption and decentralized distribution. However, the greatest threat comes from user behavior, not the system itself.


Several projects and cryptocurrencies have emerged to enhance protection, whether through securing networks, providing identity solutions, or detecting cyber attacks.


1. Quantstamp QSP
Goal: Automatically audit smart contracts and discover vulnerabilities before launching projects.
Security Contribution: Reduces the rate of coding errors that lead to hacks or losses.

2. Hacken HAI
Field: A project focused on internet security and Web3, providing ethical hacking services, security audits, and network monitoring.
Usage: Used by DeFi and NFT projects to ensure code and infrastructure protection.

3. Nym NYM
Goal: Protect privacy through a decentralized browsing network that uses mixnet technologies to encrypt and route data.
Benefit: Makes tracking users and surveillance nearly impossible.

4. NuCypher NU
Function: Encrypting data and securely storing it on the blockchain with an access control system.
Field: Used in decentralized services that require the protection of sensitive data.

5. Sentinel DVPN
Project: A decentralized VPN network that allows users to browse the internet without censorship or tracking.
Security Contribution: Enhances digital privacy and combats censorship.

6. Keep Network KEEP
Field: Protecting private data (such as private keys) within "Keeps," which are encrypted smart contracts.
Goal: Use private information within applications without exposing it to the public or network.

These projects are not just protective tools; they are considered a cornerstone in the structure of Web 3.0, where users share in securing the network and data. In a decentralized world, security becomes a collective responsibility, and these currencies provide the infrastructure for that.
