1. Blockchain
Definition:
A blockchain is a decentralized, distributed ledger technology that records
transactions across multiple computers in a way that the registered
transactions cannot be altered retroactively.
Explanation: Each transaction is bundled into a "block" and added to a
chain of previous transactions. This structure ensures transparency and
security, as changes to any single block would require altering all subsequent
blocks, which is computationally impractical.
2. Block
Definition:
A block is a collection of data that includes a list of transactions, a
timestamp, and a reference to the previous block in the chain.
Explanation: Blocks are the fundamental units of a blockchain. They store data in a
structured format, and each block is linked to its predecessor via a
cryptographic hash, ensuring the integrity of the blockchain.
3. Ledger
Definition:
A ledger is a book or database where financial transactions or other data
entries are recorded.
Explanation: In blockchain technology, a ledger is a digital record maintained
across a distributed network of nodes. Unlike traditional ledgers, blockchain
ledgers are immutable and transparent, with all participants having access to
the same version of the record.
4. Decentralization
Definition:
Decentralization refers to the distribution of authority, control, and
decision-making away from a central entity.
Explanation: In blockchain, decentralization means that no single party has control
over the entire network. Instead, control is distributed across all
participants, reducing the risk of central points of failure and increasing
transparency.
5. Consensus Mechanism
Definition:
A consensus mechanism is a protocol used by blockchain networks to agree on the
validity of transactions and the state of the ledger.
Explanation: Consensus mechanisms ensure that all nodes in a blockchain network
agree on the state of the blockchain, maintaining consistency and preventing
conflicts. Examples include Proof of Work (PoW), Proof of Stake (PoS), and
Delegated Proof of Stake (DPoS).
6. Proof of Work (PoW)
Definition:
Proof of Work is a consensus mechanism where nodes (miners) compete to solve

the problem. This process secures the network and validates transactions.
7. Proof of Stake (PoS)
Definition:
Proof of Stake is a consensus mechanism where validators are chosen to create
new blocks and validate transactions based on the number of coins they hold and

Hard cap refers to the maximum amount of funds that can be raised in a token
sale or fundraising event.
Explanation: Hard caps set a limit on the total investment accepted during a
fundraising round, ensuring that the project does not raise more than its
planned target. They help manage the funding process and maintain project
goals.
99. Soft Cap
Definition:
Soft cap refers to the minimum amount of funds required to proceed with a token
sale or fundraising event.
Explanation: Soft caps establish a threshold for the project to achieve before it
can move forward. If the soft cap is not reached, the project may not proceed
or may refund investors.
100. Decentralized Storage
Definition:
Decentralized storage is a method of storing data across a distributed network
of nodes rather than a centralized server.

System) and Filecoin, offer increased security, redundancy, and resilience by
distributing data across multiple locations.
