What is blockchain technology and how does it work?
It is a decentralized information recording system, it allows you to record transactions and store data in a secure, transparent and tamper-resistant way.
Types of existing blockchains: public, private, hybrid and consortium.
Possible applications beyond cryptocurrencies such as: smart contracts, online voting, healthcare and more.
If you are reading this article, you are probably interested in knowing more about what blockchain is, and we are here to explain it to you.
Blockchain technology is a distributed ledger system that uses cryptography to allow multiple parties to trust a shared database .
It is made up of a Blockchain, where each block contains a series of transactions and a cryptographic link to the previous block. This allows the data to be secure and cannot be altered, since any attempted alteration would be evident in the chain.
It is primarily used for recording financial transactions , such as cryptocurrencies, but its use is also being explored in a variety of applications, such as supply chain management, digital identity, and online voting.
In summary, Blockchain is a decentralized , secure and transparent system where transactions are recorded in blocks that are joined together through a cryptographic link, allowing multiple parties to trust the same shared database.
What are blockchains for?
They serve to record transactions in a Ecuador Mobile Number List secure , transparent and immutable manner. Its technology allows multiple parties to trust a shared database without the need for a central intermediary. This reduces costs and increases efficiency.
Blockchains therefore have great potential to be used in a variety of applications, such as:
Allow the use of cryptocurrencies : it is the technological basis for the operation of a cryptocurrency, providing you with a secure and transparent record of transactions.
Offer security and privacy in transactions : By using cryptography to protect transactions and hide sensitive information, crypto blockchains offer you a high level of security and privacy in transactions.
Provide a decentralized payment system : By not relying on a third party to process transactions, blockchains provide you with a decentralized payment system that is not subject to the intervention or control of a central entity.
Allow the use of smart contracts : they offer you the possibility of using smart contracts, which allow you to automate processes and execute actions autonomously based on certain conditions.
Types of blockchains that exist
There are several types of blockchains, each with different characteristics and objectives.
Public Blockchain: It is a network open to anyone who wants to join and participate in it. This means that anyone can download a copy of the blockchain ledger, and anyone can submit transactions to the network and be a validator (Proof of stake) or miner (Proof of work) node.

Private blockchain : It is a non-decentralized network of records in which access and authority are restricted to a specific group of participants. Only authorized members can access the network, verify transactions and create new blocks. Consensus mining is not necessary to validate transactions on a private blockchain.
Hybrid Blockchain – It is a combination of public and private blockchain. This type of network allows public and private transactions to be carried out on the same network. Public transactions are visible to anyone on the network, while private transactions are only visible to authorized participants. Hybrid blockchain can offer the best of both worlds.
Consortium Blockchain – is a type of network maintained and operated by a group of organizations, rather than a single entity. These organizations, known as “consortium members,” come together to form a network and agree to certain standards and protocols to maintain the ledger and validate transactions.
