The block chain provides Bitcoins public ledger, an ordered and timestamped record. This system is used to protect against double spending. Each full node in the Bitcoin network independently stores a block chain. Swipe your finger to guide a snake of balls and break the bricks. Try to break as many bricks as possible.

The validation rules these. This section describes many of. Bitcoin Core. Block Chain Overview. The illustration above shows a simplified version of a block chain. A block of one or more new transactions. Copies of each transaction are hashed, and the hashes are then paired. The merkle root is stored in the block header. Each block also. stores the hash of the previous blocksheader, chaining the blocks. This ensures a transaction cannot be modified without. Transactions are also chained together. Bitcoin wallet software gives. Each. transaction spends the satoshis previously received in one or more earlier. A single transaction can create multiple outputs, as would be. Any subsequent reference is a forbidden double. Outputs are tied to transaction identifiers TXIDs, which are the hashes. Because each output of a particular transaction can only be spent once. Unspent Transaction Outputs UTXOs or spent transaction outputs. For a. payment to be valid, it must only use UTXOs as inputs. Ignoring coinbase transactions described later, if the value of a. Bitcoin. miner who creates the block containing that. For example, in the illustration above, each transaction spends 1. Proof Of Work. The block chain is collaboratively maintained by anonymous peers on the network, so. Bitcoin requires that each block prove a significant amount of work was invested in. Chaining blocks together makes it impossible to modify transactions included. As a. result, the cost to modify a particular block increases with every new block. The proof of work used in Bitcoin. A good cryptographic hash algorithm converts arbitrary data into a. If the data is modified in any way and. To prove you did some extra work to create a block, you must create a. For. example, if the maximum possible hash value is 2. In the example given above, you will produce a successful hash on average every other try. You can even estimate the probability. Bitcoin assumes a linear probability that the lower it makes the target threshold, the more hash attempts on average will need to be tried. New blocks will only be added to the block chain if their hash is at. Every 2,0. 16 blocks, the network uses timestamps stored in each. The ideal value is. If it took fewer than two weeks to generate the 2,0. If it took more than two weeks to generate the blocks, the expected. Note an off by one error in the Bitcoin Core implementation causes the. Because each block header must hash to a value below the target. Bitcoin network expended. Only if you acquired a majority of the networks hashing power. The block header provides several easy to modify fields, such as a. Intel(R) 82579V Gigabit Network Connection Driver there. Also, only the 8. IO, and adding additional. Block Height And Forking. Any Bitcoin miner who successfully hashes a block header to a value. These blocks are commonly addressed. Bitcoin. block block 0, most commonly known as the genesis block. For example. block 2. Multiple blocks can all have the same block height, as is common when. This. creates an apparent fork in the block chain, as shown in the. When miners produce simultaneous blocks at the end of the block chain, each. In the absence of. Eventually a miner produces another block which attaches to only one of. This makes that side of. Assuming a fork only contains valid. Stale blocks are also sometimes called orphans or orphan blocks, but. Long term forks are possible if different miners work at cross purposes. Since multiple blocks can have the same height during a block chainfork, block. Instead, blocks. are usually referenced by the hash of their header often with the byte order reversed, and in hexadecimal. Transaction Data. Every block must include one or more transactions. The first one of these. The UTXO of a coinbase transaction has the special condition that. This temporarily. Blocks are not required to include any non coinbase transactions, but. All transactions, including the coinbase transaction, are encoded into. The rawtransaction format is hashed to create the transaction. From these txids, the merkle tree is constructed by pairing each. If there are. an odd number of txids, the txid without a partner is hashed with a. The resulting hashes themselves are each paired with one other hash and. Any hash without a partner is hashed with itself. The. process repeats until only one hash remains, the merkle root. For example, if transactions were merely joined not hashed, a. ABCDEEEE Merkle root. ABCD EEEE. . AB CD EE E is paired with itself. A B C D E. Transactions. As discussed in the Simplified Payment Verification SPV subsection. The full peer does not need to be trusted it is. For example, to verify transaction D was added to the. SPV client only needs a copy of the C, AB, and EEEE hashes in addition to the. If the five transactions in this block were all at. Note If identical txids are found within the same block, there is a possibility that the merkle tree may collide with a block with some or all duplicates removed due to how unbalanced merkle trees are implemented duplicating the lone hash. Since it is impractical to have separate transactions with identical txids, this does not impose a burden on honest software, but must be checked if the invalid status of a block is to be cached. CVE 2. 01. 2 2. Consensus Rule Changes. To maintain consensus, all full nodes validate blocks using the same. However, sometimes the consensus rules are changed to. When the new rules are. A block following the new consensus rules is accepted by upgraded. For example, a new. A block violating the new consensus rules is rejected by upgraded. For example, an abusive. In the first case, rejection by non upgraded nodes, mining software. This creates permanently divergent chainsone for non upgraded. In the second case, rejection by upgraded nodes, its possible to keep. Thats because, in this case, non upgraded. This is called a soft. Although a fork is an actual divergence in block chains, changes to the. For example, increasing the block size above 1 MB. In this example, an actual block chainfork is. Consensus rule changes may be activated in various ways. During Bitcoins. Satoshi Nakamoto performed several soft forks by just. Multiple soft forks such as BIP3. Such forks activated via a flag day are known as. User Activated Soft Forks UASF as. Salmiya Wikipedia. This article is about the area in Kuwait. For Kuwaiti football club, see Al Salmiya Club. Salmiya Arabic transliterated As Slmyah is a city area in Hawalli Governorate in the State of Kuwait. Salmiya is administratively divided into 1. The blocks located closer to the interior of the district tend to be mostly residential, while those located beside the Persian Gulf coastline have a great deal of commercial and up scale residential real estate. The interior residential areas boast a huge population of foreigners consisting mainly of those from the Indian sub continent and other Arabs who are not native to the Persian Gulf area. FacilitieseditSalmiya is also host to numerous mosques, an aquarium, a Scientific Center, an IMAX movie theater, football stadium, medical centers, a Roman Catholic Chapel, the district passport office Jawazat and a well equipped park beside the 5th Ring Road. Notable malls include the Salmiya Souq Mega mall which was the first mall in the nation, Marina Mall in the Marina World shopping and entertainment district, and the Omariya mall. The Gulf Road is coveted for its amazing sea vistas and is the main hub for new construction of future buildings and renovations. A boulevard passing through much of coastal Salmiya is a reflection of Kuwaits drive to modernity. The Salem Al Mubarak Street shopping districts, commonly known as Salmiya Center, runs down the outer blocks of Salmiya. It is one of the oldest and largest shopping districts of Kuwait. It is a remnant of Kuwaits once numerous traditional souk bazaars, similar to the ones located in Jleeb Al Shuyoukh and Kuwait City. Well known in the past for pearls, gold and jewellery, it now consists of a wide array of world renowned retail giants and local outlets. Much of the old souk had been built over, but the feel and atmosphere of the past albeit remains visible at the traditional precincts of this shopping district. The experience varies from modernized and Westernized in the strip malls, to a true Kuwaiti experience on some of the back streets. It is notable to point out that the more eastward away from the capital one moves along the strip, the fancier and pricier the shops are in general. There are many gold and fabric shops in the Old Souk area located onwards from the intersection of the 4th Ring Road and the strip. HistoryeditSalmiya has been a model district in the context of modernization. It has undertaken a major face lift in recent times primarily due to ever expanding commercial real estate on the Gulf Road. The popular Salem Al Mubarak Shopping strip is in relative close proximity to the capital. The boom in real estate in Salmiya has seen its demographics being constantly on the move. Increasing rental prices have gradually pushed out its working class expatriate community towards the interior districts of Kuwait. The influx of foreigners to Salmiya is of historical importance dating as far back as the 1. During the Gulf War Salmiya was destroyed by invading Iraqi occupation, but from 1. The old rugged 3 storied buildings and open fields, that Salmiya was famous for, have given way to high density layouts of high rise apartments and complexes. The beach front, once a hub and harbor for the fishing and pearl diving community, has been transformed into a well developed and modern bustling commercial avenue. Salmiya is also one of the most expensive area for real estate in the country. EducationeditThere are several educational institutions located in Salmiya. The American University of Kuwait which is only walking distance from the heart of Salmiya Centre. Also nearby is the Gulf English School and The French School of Kuwait. There is a large number of schools catering to different nationalities. Notably among these are the Indian, Arab, and Pakistani schools present in the area serving their respective communities. The Pakistan School and College which is the oldest school in Kuwait. The Indian Community School, and Indian English Academy School a branch of Don Bosco Schools, India and Indian Public School are notable schools that largely cater to the Indian community in Salmiya.

It is hoped the facility will help develop cricket in Kuwait, as well as luring international teams to play neutral matches there. The ground is due for completion in 2. Transportationedit. The Water front in Salmiya, Kuwait. Some of the major roads connecting Salmiya are the 4th Ring road, 5th Ring road, and the Gulf Road. There are 2 major bus operators, City Bus and the Kuwait Public Transportation Company, serving all major routes along Salmiya. Taxis are widely available in Salmiya and one can expect to pre bargain about the fares. Salmiya Park will be a big park situated in the heart of Salmiyah.
