Id hash transakcie na blockchaine

Monero je decentralizovaná platobná sieť, na ktorej sa používa rovnomenná kryptomena Monero (XMR). Jedná sa o súkromnú, nevystopovateľnú open-source kryptomenu dostupnú pre každého. Pre pripomenutie uvediem, že ani Bitcoin nie je úplne anonymný. Všetky transakcie sa dajú spätne dohľadať v blockchaine.

Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data (generally represented as a Merkle tree ). By design, a blockchain is resistant to modification of its data. V blockchaine sú ale transakcie všetkých, nie len mňa. ktorá má na vstupe transakciu a predošlý hash. Na riadku 16 si inicializujeme nounce číslom 0 a na riadku 17 si vypočítame prvý hash, Pre každý blok vypočítame hash z predošlého hashu, transakcie a nounce, či sa tento hash rovná hashu tohto bloku. Bitcoin ako taký nikdy nemáte pri sebe. Je uložený na adrese na internete, kde informáciu o zostatku udržiava každý užívateľ siete.

The two things represent the same number, but they are both useful because on the one hand dealing with a bitcoin address gives us the security of having an embedded 4 bytes checksum (so we don't transfer money by mistake to something that isn't a valid address), and on the other hand, dealing with the Hash 160 only (20 bytes) is more efficient for the purpose of encoding a transaction.

Começou agora e seremos mui For example, if the hash target is 0000a1b2c3d4e5f6, any hash less than or equal to this number is a valid block hash. Many hashes would satisfy this requirement, and anyone of those would be valid. However, it is a tough task to find such a hash. Lesser the hash target, the more difficult it is to find a valid hash.
