Staking rewards in Proof-of-Stake networks tend to start high and decrease as the network grows. Users often read this as someone cutting the rate. In DecimalChain, the explanation lies in the reward math of the network itself.
What APR shows in a PoS network
APR is an estimated annual reward rate for delegating coins to validators. In DecimalChain, it depends on network parameters: the emission volume, the total amount of DEL in delegation, the user's share of the stake, and the validator's commission and performance. The value changes together with these parameters, so it works as a current network indicator.
Why early-stage networks offer higher rates
A young PoS network needs a large total stake to secure consensus. Higher rewards attract the first delegators. DecimalChain launched in August 2020 and followed the same path: few participants, a small stake, and a high share of rewards per delegated coin.
The reward math
Imagine the network distributes the same volume of rewards over a period. Divided among 1 million coins, each thousand receives one share. When the stake grows to 10 million coins, the same rewards are split among ten times more coins, and the percentage per coin goes down.
The security effect
A bigger stake raises the cost of influencing consensus: an attacker would need to control a much larger volume of coins. Decreasing rates and growing security are two sides of the same process.
Why moderate emission matters
A high APR means fast issuance of new coins. When supply grows faster than real usage (fees, token creation, reserves, settlements), the economy loses balance. Mature networks slow emission down and shift the focus to coin utility. In DecimalChain, DEL serves as the network's fuel: it pays for transactions, backs custom tokens, and powers internal settlements.
Hold mechanics
DecimalChain adds an extra reward for long-term participation. Users who lock DEL for a year or more receive a share of a bonus pool distributed among all Hold participants. Long-term locking stabilizes the stake and reduces the chance of large volumes quickly returning to circulation. Rewards are paid out by active validators that take part in block creation.
What matters long-term
APR shows the speed at which new coins are distributed. The long-term value of a network depends on how many tasks its coin performs. Current figures and detailed calculations are available in the original article: decimalchain.com/blog/pochemu-apr-decimal-snizhaetsya-en/
