    Another cryptocurrency based on the blockchain principle. Provides a platform for programmable smart contracts. The "ethers" are seen by fans as the legitimate successors of the Bitcoins (see also the picture above).
  2. Cryptlet
    Service developed by Microsoft for the Azure cloud, with the help of which users can enter external data into a blockchain without destroying its security and integrity. As individualized middleware, cryptlets can also be developed by Azure users themselves - in any programming language - and are intended to bridge the gap from the blockchain to new business services in the cloud.
  3. Cryptocurrency
    Digital money, without coins and bills. With the help of cryptography, a distributed, secure and decentralized payment system is built. Does not need banks, but computing power and technical aids such as the blockchain.
  4. Blockchain
    A blockchain is a decentralized database that keeps a constantly growing list of transaction data records. The database is expanded linearly in chronological order, comparable to a chain, to which new elements are constantly being added at the lower end (hence the term "blockchain"). When a block is complete, the next is created. Each block contains a checksum of the previous block.

    The technical model of the blockchain was developed in the context of the cryptocurrency Bitcoin - as a web-based, decentralized, public accounting system for all Bitcoin transactions that have ever been made.

    The open source software validates the entire blockchain and was approved at the beginning of 2009 by a certain " Satoshi Nakamoto " published under the name" Bitcoin ". Bitcoin Core was initially programmed in C ++ primarily for Windows systems. Porting to GNU / Linux followed a little later. Because the developers fell out, there are now some derivatives of Bitcoin software, including Bitcoin XT, Bitcoin Unlimited or Bitcoin Classic.
  6. BigchainDB
    The "scalable blockchain database" can manage up to a million write operations per second, store petabytes of data and still have a latency of less than a second - all of this managed in a decentralized manner and with the highest data integrity. The technical basis is blockchain technology.
  7. Distributed ledger
    Financial term for "distributed account management". Bitcoin is a completely new technical approach to distribute information about certain mappings. There is no longer a classic account that is managed centrally at a bank, but "account management" is based on a network of communicating systems.
  8. Smart contract
    A computer protocol that can map or check contracts or provide technical support for the negotiation of a contract. Could replace the written contract in the future.
  9. R3CEV
    The startup R3 CEV is building the blockchain-based "Global Fabric for Finance". The world's largest blockchain is to be developed with around 50 financial partners - a first test run with eleven major banks, including Barclays, Credit Suisse, HSBC, UBS and UniCredit, has already been successfully completed. R3CEV has entered into a strategic partnership with Microsoft to develop blockchain infrastructure and technology in the Azure cloud.
  10. Ripple
    An open source protocol for a payment network - currently still in development. P2P payment method and foreign exchange market in one, based on the crypto currency "XRP". However, Ripple users are not limited to this one currency, but can use any currency - for example euros, dollars or yen.
