BLOCKCHAIN Network

 The Blockchain network seeks to ensure security by decentralizing data. They are distributed, encrypted and shared databases that store information about all transactions that occur between network users (CHICARINO et al. , 2017). All nodes in the network must contain the same information; in this way, when a new block is inserted, all nodes are updated to receive the new information and thus contain the same content again.


The blocks are structures that store the information contained in the network and are organized in a chain (WATTERS, 2016). Each block holds a reference to its previous one; in this way, it is possible to go through the entire chain until reaching block zero, also called block genesis. This block is coded by the software when the network is created and serves as the initial state of the system, keeping information about how the network should behave during its operation. Due to the chaining of the blocks, it is not possible for one of them to be changed without this being noticed by the others in the network. In order to make a change, it would be necessary to regenerate all the subsequent blocks of the chain, which in a large network would become unviable from a computational point of view.

Desktop Support Technician is known as one of the backbones of IT organization. They are also accountable for groundwork, installation, and maintenance of end user workstation equipment (laptops/ desktops) and additional peripherals including IP telephones.

Each block consists of two main parts: the header, where the block's identification information is stored, such as the hash [i] of the previous block and the nonce , and the transactions, which consist of grouping the data that is stored in the block.

Is it worth taking a free English proficiency test?

 There are several options for free English proficiency tests. They are great options as pre-tests for you to check if you are already prepared to carry out a real, certified assessment. Thinking of a free test as an official document to prove your fluency in the language will not have the desired effect, as just as the certificates issued by language schools, the free proficiency test diplomas are not valid or accepted in most companies and educational institutions. In that case, search for a renowned certification organization that offers a widely accepted diploma within your scope. Earning a certificate of proficiency is the beginning of a new stage in your career.

DDoS Attacks: Growing?

While distributed denial of service (DDoS) attacks have been around since the late 1990s, they have picked up in volume and intensity over the past year. what is distributed denial of service ? The largest DDoS on record hit the Internet at the end of March. A pair of studies released this week from Arbor Networks and Akamai Technologies further reinforces the notion that DDoS is a growing threat, depending on how you interpret the data. DDoS Getting Bigger According to Arbor, at the end of the first quarter of 2013 the average size of DDoS attacks was 1.77 Gbps, which is a 19.5 percent increase over the same period in 2012. Larger attacks are also growing, with DDoS incidents delivering packet floods in the 2 to 10 Gbps range now representing 21.5 percent of all attacks, up from 15 percent a year ago. While DDoS attack size is rising, Arbor reports that 62.4 percent of attacks are still less than 1 Gbps. Considering that many large enterprises and data centers have Internet
