Block field
| Глоссарий геологических терминов |
A thin accumulation of stone blocks, typically angular, with only coarse fragments in the upper part, over solid or weathered bedrock, colluvium, or alluvium, without a cliff or ledge above as an apparent source. block fields occur on high mountain slopes above tree-line, or in polar or paleo-periglacial regions; they are most extensive along slopes parallel to the contour; and they generally occur on slopes of less than 5%. synonym - felsenmeer. compare - block stream, talus slope, scree slope. gg

- (in mechanics termed a pulley.) blocks are flattish oval pieces of wood, with sheaves in them, for all the running ropes to run in. they are used for various purposes in a ship, either to increase the mechanical power of the ropes, or to arrange the ends of them in certain places on the deck, that they may be readily found when wanted; they are consequently of various sizes and powers, and obtain various names, according to their form or situation, thus:—a single block contains only one sheave or wheel. a double block has two sheaves. a treble or threefold block, three, and so on. a long-tackle or fiddle-block has two sheaves—one below the other, like a fiddle. cistern or sister block for top-sail lifts and reef tackles. every block is composed of three, and generally four, parts:—(1.) the shell, or outside wooden part. (2.) the sheave, or wheel, on which the rope runs. (3.) the pin, or axle, on which the sheave turns. (4.) the strop, or part by which the block is made fast to any particular station, and is usually made either of rope or of iron. blocks are named and distinguished by the ropes which they carry, and the uses they serve for, as bowlines, braces, clue-lines, halliards, &c. &c. they are either made or morticed (which see).

Block (on the bitcoin blockchain), английский
Data is permanently recorded in the bitcoin network through files called blocks. a block is a record of some or all of the most recent bitcoin transactions that have not yet been recorded in any prior blocks. new blocks are added to the end of the record (known as the blockchain), and can never be changed or removed once written (although some software will remove them if they are orphaned). each block memorializes what took place in the minutes before it was created. each block contains a record of some or all recent transactions and a reference to the block that came immediately before it. it also contains an answer to a difficult-to-solve mathematical puzzle – the answer to which is unique to each block. new blocks cannot be submitted to the network without the correct answer – the process of “mining” is essentially the process of competing to be the next to find the answer that “solves” the current block. the mathematical problem in each block is extremely difficult to solve, but once a valid solution is found, it is very easy for the rest of the network to confirm that the solution is correct. there are multiple valid solutions for any given block – only one of the solutions needs to be found for the block to be solved. because there is a reward of brand new bitcoins for solving each block, every block also contains a record of which bitcoin addresses or scripts are entitled to receive the reward. this record is known as a generation transaction, or a coinbase transaction, and is always the first transaction appearing in every block. the number of bitcoins generated per block starts at 50 and is halved every 210,000 blocks (about four years). bitcoin transactions are broadcast to the network by the sender, and all peers trying to solve blocks collect the transaction records and add them to the block they are working to solve. miners get incentive to include transactions in their blocks because of attached transaction fees. the difficulty of the mathematical problem is automatically adjusted by the network, such that it targets a goal of solving an average of 6 blocks per hour. every 2016 blocks (solved in about two weeks), all bitcoin clients compare the actual number created with this goal and modify the target by the percentage that it varied. the network comes to a consensus and automatically increases (or decreases) the difficulty of generating blocks. because each block contains a reference to the prior block, the collection of all blocks in existence can be said to form a chain. however, it’s possible for the chain to have temporary splits – for example, if two miners arrive at two different valid solutions for the same block at the same time, unbeknownst to one another. the peer-to-peer network is designed to resolve these splits within a short period of time, so that only one branch of the chain survives. the client accepts the ‘longest’ chain of blocks as valid. the ‘length’ of the entire block chain refers to the chain with the most combined difficulty, not the one with the most blocks. this prevents someone from forking the chain and creating a large number of low-difficulty blocks, and having it accepted by the network as ‘longest’
