Blockchain technology first emerged in 2009 and has become a disruptive technology that goes beyond the crypto world. This technology is becoming widely used in a range of software applications across various industries. Cryptographic ledgers have become the technology of choice for secure transactions within software applications, beyond cryptocurrency transactions.
Cryptographic Ledgers Defined
A blockchain is defined as a distributed database comprised of a collection of blocks of data. Each of these blocks has a timestamp and a cryptographic link to a previous block, as well as the other data it may store. The database is maintained by a network of computers, called nodes, and is secured through encryption and cryptography. While the database can be read by almost anyone, no single user can update or edit it.
Each block contains data, known as a payload, a time-stamp of its creation, an identifying hash value, and the previous block’s hash value. The payload can be anything, such as a list of transactions, smart contracts code, inventory lists, images, music files, documents, and more. The hash value is a string of numbers that serve as an identifier for the data within the block.

Use Cases for a Distributed Ledger
A distributed ledger is the underlying technology for all cryptocurrency software, including crypto wallets. These wallets keep your private keys secure and accessible, so you can initiate cryptocurrency transactions. Crypto wallets come in many forms including hardware wallets and mobile apps, making it easy to use digital currency for purchases online.
One of the best cryptocurrency hardware wallets on the market today is Trezor. It was the first crypto hardware wallet in the world when it was created by SatoshiLabs in 2014, and the first wallet to offer a recovery seed and passphrase protection. The trusted source for all things crypto, CryptoVantage, provides an in-depth overview of the new features of the Trezor One.
The hardware wallet provides an intuitive user experience, thanks to easy setup and use. Users can purchase digital currencies and tokens through the Trezor Wallet app, as well as exchange crypto assets. The Trezor hardware wallet is highly secure and comes with step-by-step customer support. Users can purchase digital currency on the Trezor Wallet app using fiat, allowing them to securely store crypto assets immediately. The hardware wallet supports over 1,000 cryptocurrencies, both mainstream coins, and obscure altcoins.
Even though new fintech apps make peer-to-peer buying, selling, and lending easier, making international money transfers costs a lot of time and money. Traditional banking systems are centralized, and therefore store sensitive data in a central database. Each bank adheres to different rules and regulations, which results in lengthy and costly international transactions. Making an international transfer via cryptographic ledger technology means financial institutions can join their networks and initiate transactions with cryptocurrency.
