🧮 Hash and hashing algorithms are key concepts that newcomers to the blockchain know about and which always go hand in hand with security.
⠀
♨️ To maintain decentralized networks and consensus mechanisms, including Bitcoin or #Ethereum with a thousand nodes connected via p2p, a “lack of trust” and an effective confirmation system are necessary. These #networks need compact methods of encrypting information that would allow participants to conduct quick and secure checks.
⠀
🔳 #Block is one of the main components of #Bitcoin and Ethereum. The block contains information about transactions, timestamps, and other significant metadata. A considerable role in ensuring #security is played by the ability to compress large amounts of information about the global network status into short standard messages, which can be easily checked if necessary. These messages are the hash.
⠀
⚜️ Hash algorithms in #cryptography are used everywhere. The main areas of their application are the #storage of passwords, file verification systems, etc. The essence of these hashes is to use a deterministic algorithm that takes input and creates a string with a fixed length. Thus, the same input will always be converted to the same output.
⠀
Determinism is important not only for hashes because even if you change one bit of the input data, you also get a completely different hash.
⠀
🌀 However, there is a problem with #hashing algorithms - this is the inevitability of collisions. Collisions are bad. This means that the attacker who created the collisions can transfer malicious files while hiding under the correct hash. A good hash #function should make it more difficult for attackers to find ways to create an input with the same hash value.
⠀
♻️ The process of calculating the hash should not be too effective since in this case, #attackers can easily calculate collisions. Hash #algorithms must be resistant to the attacks of finding the pre-image. It is necessary to complicate the process of calculating steps to find the initial value from which the hash was created (for example, the inverse image).
⠀
🌐 𝗥𝗲𝗹𝗶𝗰𝘁𝘂𝗺 𝗣𝗿𝗼 is a supplemented modification of #SHA1-based hashing mathematics. The main advantage of it is in converting from 20 #bytes to 32 bytes (in your own hash). This gives a high crypto-stability, including from a promising quantum computer.

Hi there! 👋🏻 Today, we will tell you about distributed storage and its advantages.
⠀
The search for the effective use of blockchain #technology extends not only to the financial sector and everything related to it, but also to areas such as distributed data storage. Despite the relatively high efficiency and popularity, centralized storages have a number of problems that make the option of using distributed storages more attractive.
⠀
At the moment, distributed data storage, along with distributed computing, is one of the main trends in the blockchain #economy. Many projects are still under development, but if the growth dynamics of the blockchain #market continues, soon distributed storage on the blockchain will compete with each other. And the main parameters of competition will be speed, scalability, #security and low cost of services.
⠀
🏆 The idea of using a blockchain for distributed #data storage is obvious to many, and here’s why:
🔹 Distributed #storage does not require acknowledgment of receipt of data.
🔹 Faster search for fragmented files and viewing them through the organization of various chains of smart contracts.
🔹 Download speed is significantly higher than on a #P2P network.
⠀
🏆 𝗥𝗲𝗹𝗶𝗰𝘁𝘂𝗺 𝗣𝗿𝗼 𝗱𝗶𝘀𝘁𝗿𝗶𝗯𝘂𝘁𝗲𝗱 𝘀𝘁𝗼𝗿𝗮𝗴𝗲 𝗮𝗱𝘃𝗮𝗻𝘁𝗮𝗴𝗲𝘀:
🔹 Access speed — Instant access
🔹 Storage period — Life-long
🔹 Information protection Use of Smart contract - "Copyright"
🔹 Reliability — Total #decentralization
🔹 Usage Environment: All business human activities
⠀
🏆 𝗥𝗲𝗹𝗶𝗰𝘁𝘂𝗺 𝗣𝗿𝗼 𝘀𝗼𝗹𝘃𝗲𝘀 𝗲𝘅𝗶𝘀𝘁𝗶𝗻𝗴 𝗽𝗿𝗼𝗯𝗹𝗲𝗺𝘀:
⠀
✅ 𝗟𝗶𝗳𝗲𝘁𝗶𝗺𝗲 𝘀𝘁𝗼𝗿𝗮𝗴𝗲
The ability to store any type of data of any size with instant access to it. Distributed data remains in the system forever, unlike any #hosting.
⠀
✅ 𝗖𝗼𝗽𝘆𝗿𝗶𝗴𝗵𝘁 𝗽𝗿𝗼𝘁𝗲𝗰𝘁𝗶𝗼𝗻
Automatically organizes copyright with the recognition of intelligent digitized work and a pirated copy. #Reward to an author for the use of materials is automated, bypassing intermediaries (using the "Copyright" smart contract).
