The technology that supports cryptocurrencies is characterized by decentralization, immutability, and transparency, which is touted as one of the most differentiating attributes of traditional forms of payment, conditioned by the fact that it is the only one. hermetism of institutions and platforms that
The block strings in which transactions with cryptocurrencies are recorded are usually public, without compromising the privacy of users. Well, even if someone who wishes can locate who sends and receives funds – or other assets – via the chain of blocks that does not mean that this person has access to the # 39 identity of the network user, unless the same user provides the information or is exposed on centralized platforms such as exchange offices.
The way portfolio addresses and transactions recorded in a blockchain can be tracked is through a block browser. explora dores d blockchain are tools designed for users of the network to access their information in real time and in a secure manner. operations and other events in the chain.
Blockchain explorers establish direct contact between users and the well-known transparency of the cryptocurrency transfer protocol, which generates trust in this technology. These explorers work in a specific channel, so we do not find any that can give us information about two or more blockchains simultaneously.
In this series of CriptoNoticias specials, we will comment on the most relevant features presented by explorers of major blockchains. of the ecosystem. We will start with the two channels whose cryptocurrencies have the most capitalization on the market: Bitcoin and Ethereum. First of all, it's safe to remember what data is usually found in browsers.
One of the most basic data we have access to is the height or number of blocks, which allows us to search for information more easily. in the chain; especially if we consider that a blockchain like Bitcoin, at the present time, has more than 530 000 blocks.
A blockchain browser also allows to see the number of transactions whose information is stored in a given block, the date and the time they were made and the weight they have, measured in kilograms -octets. In addition, we can find information on how many confirmations have received transactions from a block, which are validations that are received by minors.
To this information is added, both the amount of cryptocurrencies that were sent in the block transactions, such as the commissions generated by these transactions. We can even know which mining group or mining pool was responsible for extracting each block.
Exploration of the Bitcoin blockchain
The first cryptocurrency created is the one that, for the moment, accumulates more explorers than blocks; a reality that reflects the community's interest in Bitcoin. However, the characteristics of two of the best known browsers will be analyzed: Blockchain.info and Bitcoin Block Explorer
Blockchain.info
Launched two years after the creation of bitcoin in 2011, Blockchain.info is one of the oldest explorers and used by the bitcoiner community. This allows those who enter your web portal to know the details of the transaction date, block size, commission, mining group, weight, confirmations and other block transactions, while offering statistics. and graphics. 19659023] Graphs-Statistics-Explorer-Blocks "width =" 1080 "height =" 521 "data-lazy-srcset =" https://i0.wp.com/www.criptonoticias.com/wp-content/uploads/2018 /07/Actividad-Red-Bitcoin-Blockchain.jpg?w=1228&ssl=1 1228w, https://i0.wp.com/www.criptonoticias.com/wp-content/uploads/2018/07/Actividad-Red- Bitcoin-Blockchain.jpg?

Blockchain.info users also have access to detailed data of each transaction made from a certain portfolio. In addition, the site has a channel view, which allows you to see the height of the block in which the transaction is tracked and information on the difficulty of the data mining algorithm as well as a daily transaction counter.

It is also possible to obtain information on the total reward received by the mining group after the extraction of a block, data that help to know the lucrative potential of mining activity for these conglomerates.
Bitcoin Block Explorer
Powered by the Open Source API Insight, Bitcoin Block Explorer is a browser that, like Blockchain.info, allows you to search information in the Bitcoin blockchain from the height from the block, the address or the hash of the transaction. It also offers the benefit of scanning the QR code of a transaction to locate the data that corresponds to it.
The transaction number of the block, the weight, the reward, the date, the mining group, the previous block and the difficulty are the basic data provided by this explorer. This, in addition to the merkle root formed from the identifiers of the transaction. In addition, s important to note that the explorer Bitcoin Block Explorer also supports the testnet (bitcoin test network).

Another peculiarity of this site is that you can find information on other blockchains like Zcash or Bitcoin Cash, however, as mentioned above, this is not the same browser, but on this page
Exploring the Ethereum blockchain
Second cryptocurrency with a greater capitalization of the ecosystem, l & rsquo; Ether (ETH), belongs to the blockchain of Ethereum, whose blockchain works differently from Bitcoin, thanks to the peculiarities that differentiate them. For this reason, transactions in Ethereum can be tracked through different browsers than those mentioned above.
The blockchain developed by Vitalik Buterin and his team in 2014 and launched in 2015. Ethereum is one of the most used to support cryptoactive news, thanks to the protocols it manages, and to decentralized applications ( Dapps).
EtherScan
One of the most used browsers among ETH users is EtherScan . E This platform does more than just show and enable the tracking of cryptoactives based on the Ethereum blockchain and the ether itself, as it has multiple analytical options.
Etherscan allows the ether user to see in detail the blocks that make up the chain and the transactions in real time, in addition to the graphs of the native crypto-currency behavior of 39; Ethereum in the last 14 days which is show first after accessing the website.

When one goes into the details of a transaction, the user can know the hash of the transaction, the gas or the commission paid to the miners, the height of the block and confirmations that it carries with the status of the transaction and the time it took to be processed.
In addition, the browser has the ability to display the location of a specific transaction in the chain and also offers a mining calculator that allows ETH miners to Have an estimate of the consumption and revenues related to this activity; a service that encourages fans to obtain detailed technical information reliably.
Other services available in EtherScan are Smart Signature Verification, Explorers for Test Networks, and a whole section of options for developers interested in APIs (Application Programming Interface, by its acronym in English) d & # 39; Ethereum.
It is important to keep in mind that, being Ethereum the block chain in which the altcoins were built the most, the block explorer has the ability to explore the transactions of tokens such as VeChain, Aeternity and OmiseGo. These cryptoactives have the same basic information as transactions with the ether

EtherChain.org
With an option to view pending transactions, EtherChain.org is the second Ethereum browser in this collection. As in Etherscan, but with a more colorful interface, in this platform, Ethereum users can view block data and transactions.
The real-time visualization of transactions includes the general data mentioned above, as well as a specification within the limits of network commissions. Then distinguish the average price, the limit for not cluttering the network and the amount of gas used to process the transaction.

In addition, the site has a table of conversion units in the ether. This table has 11 different names for different decimal places and amounts in ETH; information of interest to Ethereum lovers.

Regarding options for developers, EtherChain also offers the signature verification service and even checks an intelligent Ethereum contract . Two tools that, added to the network node explorer and the statistics that make it possible to modify the correlations according to the interests of the consumer, superimpose this explorer before others of their peers. Blockchains are fundamental tools for ecosystem participants because they are an essential part of the process of executing transactions with cryptocurrencies. Litecoin, Ethereum Classic, Monero, Zcash, NEM, Sia and many other cryptographic currencies have their own explorers, which we will present in the next installments.
