- A stress, either compression or tension, which is applied to a material to determine the magnitude required to produce a specified permanent deformation usually specified as a percentage of the original length.
- The stress that will cause a specified small permanent set in a material.
- A specified stress to be applied to a member or structure to indicate its ability to withstand service loads.

Proof of stake, английский
Proof-of-stake (pos) is a method by which a cryptocurrency blockchain network aims to achieve distributed consensus. while the proof-of-work (pow) method asks users to repeatedly run hashing algorithms or other client puzzles, to validate electronic transactions, proof-of-stake asks users to prove ownership of a certain amount of currency (their “stake” in the currency). peercoin was the first cryptocurrency to launch using proof-of-stake. other prominent implementations are found in bitshares, nxt, blackcoin, nushares/nubits and qora. ethereum has planned a hard fork transition from pow to pos consensus. decred hybridizes pow with pos and combines elements of both in an attempt to garner the benefits of the two systems and create a more robust notion of consensus. with proof of work, the probability of mining a block depends on the work done by the miner (e.g. cpu/gpu cycles spent checking hashes). in the case of bitcoin, with proof of stake, the resource that’s compared is the amount of bitcoin a miner holds – someone holding 1% of the bitcoin can mine 1% of the “proof of stake blocks”. instead of sacrificing energy to mine a block, a user must prove they own a certain amount of the cryptocurrency to generate a block. the more stake you own, the more likely you are to generate a block. in theory, this should prevent users from creating forks because it will devalue their stake and it should save a lot of energy. proof of stake sounds like a good idea, but ironically, there is the “nothing at stake” problem. since mining bitcoins is costly, it is not smart to waste your energy on a fork that won’t earn you any money, however with proof of stake, it is free to mine a fork
Proof of work, английский
- Pow system/protocol/function is an economic measure to deter denial of service attacks and other service abuses such as spam on a network by requiring some work from the service requester, usually meaning processing time by a computer. the concept may have been first presented by cynthia dwork and moni naor in a 1993 journal. the term “proof of work” was first coined and formalized in a 1999 paper by markus jakobsson and ari juels. a key feature of these schemes is their asymmetry: the work must be moderately hard (but feasible) on the requester side but easy to check for the service provider. this idea is also known as a cpu cost function, client puzzle, computational puzzle or cpu pricing function
- One important property of a block in bitcoin, ethereum and many other crypto-ledgers is that the hash of the block must be smaller than some target value. the reason this is necessary is that in a decentralized system anyone can produce blocks, so in order to prevent the network from being flooded with blocks, and to provide a way of measuring how much consensus there is behind a particular version of the blockchain, it must in some way be hard to produce a block. because hashes are pseudorandom, finding a block whose hash is less than takes an average of 4.3 billion attempts. in all such systems, the target value self-adjusts so that on average one node in the network finds a block every n minutes (eg. n = 10 for bitcoin and 1 for ethereum).
Proof of work nonce, английский
A meaningless value in a block which can be adjusted in order to try to satisfy the proof of work condition

Compression, английский
- A state or condition of being pushed or shortened by a force.
- Сжатие
- Сжатие (данных), уменьшение размеров файла изображения. см. также lossy и non-lossy. процесс упаковки данных с целью уменьшения занимаемого ими пространства на накопителе
- Компрессия, сжатие
- The reduction of volume of a vapor or gas by mechanical means.
- Digital video pictures can be compressed with a number of techniques. these include: jpeg and jpeg-2000 (for still images), m-jpeg and mpeg (for moving pictures).
- The reduction in gain at one level of a picture signal with respect to the gain at another level of the same signal.
- A digital photograph creates an image file that is huge, a low-resolution 640x480 image has 307,200 pixels. if each pixel uses 24 bits (3 bytes) for true color, a single image takes up about a megabyte of storage space. to make image files smaller almost every digital camera uses some form of compression. see the jpg entry below.
- The application of any of several techniques that reduce the amount of information required to represent that information in data transmission. this method reduces the required bandwidth and/or memory.
- A method of reducing the size of a digital image file to free up the storage capacity of memory cards and hard drives. compression technologies are distinguished from one another by whether or not they remove detail and color from the image. lossless technologies compress image data without removing detail, while "lossy" technologies compress images by removing some detail. joint photographic experts group (jpeg) is a lossy compression format supported by jpeg, pdf and postscript language file formats. most video formats are also lossy formats. tiff files are not and, as such, are far more stable than jpegs and other lossy file formats.
- Reducing the number of bits needed to encode a digital signal, typically by eliminating long strings of identical bits or bits that do not change in successive sampling intervals (e.g., video frames).
- A digital photograph creates an image file that is enormous. to enable image files to become smaller and more manageable cameras employ some form of compression such as jpeg. raw and tiff files have no compression and take up more space.
- 1. the act of squeezing or pressing the first-aider applied compression to the chest of the casualty. 2. a serious condition in which the brain is compressed by blood or cerebrospinal fluid accumulating in it or by a fractured skull

- A reduction of the time available for a scheduled storyboard to reach its final state.
- A way of making files smaller, either to fit into restricted storage space or to speed up transmission over the internet. popular compression standards include- jpeg- and- gif- for pictures,- mp3for music files,- mpeg, mp4, avi- and- mov- for movie footage, and- zip- for just about everything else.
