Токеноміка Cardano (ADA)

Cardano (ADA) is a third-generation blockchain platform designed with a focus on sustainability, scalability, and transparency. Its token economics are structured to support a decentralized network through a fixed maximum supply and a multi-layered incentive system.

Issuance Mechanism

Cardano utilizes a capped supply model with a maximum limit of 45,000,000,000 ADA. The issuance of these tokens is divided into two primary phases:

• Genesis Minting: Approximately 31,112,484,646 ADA were minted at the network's inception. This included tokens sold during the Initial Coin Offering (ICO) and those allocated to the project's founding entities.
• Inflationary Rewards (Reserve): The remaining 13,887,515,354 ADA were placed into a "reserve." These tokens are gradually issued as staking rewards to incentivize network security and block production.
• Monetary Policy: In each five-day epoch, 0.30% of the remaining ADA in the reserve is moved into a "pot." This pot, which also includes all network transaction fees collected during the epoch, is then distributed to participants and the treasury.

Allocation Mechanism

The initial distribution of ADA was conducted through a multi-stage ICO held between September 2015 and February 2017, primarily in Asia. The allocation was distributed as follows:

Usage and Incentive Mechanism

The ADA token serves several critical functions within the Cardano ecosystem:

• Network Fees: Every transaction requires a fee paid in ADA to cover processing and storage costs. Fees are calculated using a formula: (a * size(tx)) + b, where a and b are constants that can only be adjusted via a hard fork.
• Staking and Security: Cardano uses the Ouroboros Proof-of-Stake (PoS) consensus mechanism. ADA holders can either run their own stake pool as a Stake Pool Operator (SPO) or delegate their ADA to an existing pool.
• Reward Distribution: At the end of each epoch, the "pot" (transaction fees + 0.3% of reserves) is distributed. A fixed 20% of this pot goes to the Cardano Treasury to fund ecosystem development. The remaining 80% is distributed to SPOs and delegators.
• Governance: Through the Voltaire era and proposals like CIP-1694, ADA holders can participate in on-chain governance. This includes voting on "governance actions," electing Delegate Representatives (DReps), and deciding on treasury disbursements via Project Catalyst.

Locking Mechanism

Cardano introduced formal "token locking" support during the Allegra hard fork. Unlike some other protocols where tokens are locked for security or "slashing" purposes, Cardano's locking mechanism is primarily functional:

• Governance Locking: To participate in voting, ADA holders must "lock" their tokens for a specified period. This ensures that the same tokens cannot be used to double-count votes or be moved during the voting process.
• Contractual Agreements: Locking allows the ledger to record that a specific token is reserved for a purpose, such as a smart contract or a deal settlement, preventing it from being disposed of until the conditions are met.
• No Staking Lock-up: Notably, Cardano does not require ADA to be locked for general staking. Users retain full custody of their delegated ADA and can spend or move it at any time without penalty.

Unlocking Time

Because Cardano does not enforce a mandatory lock-up period for staking, there is no "unsticking" or "unbonding" delay for delegated ADA. However, there are specific timelines related to the activation of stake and the distribution of rewards:

• Staking Activation: When a user delegates ADA, the stake becomes active after two epochs (approximately 10 days).
• Reward Cycle: Rewards for a specific epoch's work are typically distributed three epochs after the initial delegation.
• Founding Entity Vesting: While most ICO tokens were available at launch, IOG (formerly IOHK) disclosed a vesting schedule for its initial allocation. One-third was available immediately in October 2017, with the remaining two-thirds becoming available in two equal tranches on June 1, 2018, and June 1, 2019.
• Governance Deposits: Participants who register as a DRep must pay a refundable deposit of 500 ADA, which is returned only upon their retirement from the role.
