In subject area: Computer Science Block Truncation Coding (BTC) is a simple and efficient lossy image compression technique that preserves statistical moments of small blocks of the input image in the quantized output. It is a 1-bit adaptive moment-preserving quantizer that retains the block mean...
is stored in a database. Transactions are recorded in an account book called a ledger. A blockchain is a type ofdistributeddatabase or ledger, which means the power to update a blockchain is distributed between the nodes, or participants, of a public or private computer network. This is ...
Blockchain is an immutable digital ledger that supports secure transactions. It consists of a network of computers that all help record, store and verify data, making it decentralized by nature. Who created blockchain? Bitcoin was mysteriously launched by Satoshi Nakamoto — a pseudonym for a pers...
computer made a mistake in computation, it would not affect the rest of the blockchain. It would have to be committed by at least 51% of network computers for the error to spread to other blockchains. This is a difficult feat considering the number of proliferating Bitcoin-related netw...
computer network's nodes. They are best known for their crucial role in cryptocurrency systems, maintaining a secure and decentralized record of transactions, but they are not limited to cryptocurrency uses. Blockchains can be used to make data in any industry immutable—meaning it cannot be ...
It conceals errors in block-based image coding systems by using neural network. In this proposed algorithm, only the intra-frame information is used for reconstruction of the image with separated damaged blocks. The information of pixels surrounding a damaged block is used to recover the errors ...
The Minecraft Block Wizard, a plugin forBlockbench, lets you add a custom block to Minecraft without any coding experience. It makes it easy as possible to generate the block and add it to your world. After you've created your custom block, you can use Blockbench to customize it. The plu...
CBC is a specific operational mode in encryption. In this mode, each plaintext block is exclusive-OR'd orXORed(numerically combined) with the previous ciphertext block and then encrypted. An XOR is a coding mechanism or binary function used to combine different inputs. In CBC, XOR facilitates...
Smart contracts are vulnerable to coding errors, which can lead to unexpected outcomes (including faulty security measures). Network congestion and expensive transaction fees may affect contract execution and favorability. These are just a few of the primary risks to which smart contracts may be exp...
