Blockchain is a shared, immutable ledger that enables the recording of transactions and tracking of assets in a network, applicable to both tangible and intangible assets. It is considered a foundational technology rather than a disruptive one, primarily beneficial when multiple parties are involved and trust is an issue. Key components include cryptography, timestamps, immutability, and consensus algorithms, which help manage transactions without intermediaries.

2. WHAT’S BLOCKCHAIN?
Technically
“A blockchain, originally blockchain, is a growing list of record, called blocks, which are linked using cryptography. Each
block contains a cryptographic hash of the previous block, a timestamp, and transaction data.” - Wikipedia

3. BLOCKCHAIN AS TECHNOLOGY
 Blockchain is a shared, immutable ledger that facilitates the process of recording
transactions and tracking assets in a business network. An asset can be tangible (a
house, a car, cash, land) or intangible (intellectual property, patents, copyrights,
branding). Virtually anything of value can be tracked and traded on a blockchain
network, reducing risk and cutting costs for all involved. - IBM
 Blockchain is rather a Foundational technology than a Disruptive one.

5.  Do you need to store state of assets?
 Are there more than three parties involved in maintaining assets?
 Do you want to have intermediaries or third parties?
 Is there an issue of trust between the parties?
