Использование web3.js

import { Connection } from '@solana/web3.js';

const connection = new Connection('https://fra.rpc.orbitflare.com?api_key=YOUR-API-KEY');

// Get inflation governor parameters
const inflationGovernor = await connection.getInflationGovernor();
console.log('Initial inflation:', inflationGovernor.initial);
console.log('Terminal inflation:', inflationGovernor.terminal);
console.log('Taper rate:', inflationGovernor.taper);
console.log('Foundation percentage:', inflationGovernor.foundation);
console.log('Foundation term:', inflationGovernor.foundationTerm);

// Calculate current inflation rate
async function calculateCurrentInflation() {
  const inflationGovernor = await connection.getInflationGovernor();
  const epochInfo = await connection.getEpochInfo();
  
  const yearsSinceGenesis = epochInfo.absoluteSlot / (432000 * 365); // Approximate years
  const currentInflation = Math.max(
    inflationGovernor.terminal,
    inflationGovernor.initial - (inflationGovernor.taper * yearsSinceGenesis)
  );
  
  return {
    currentInflation,
    yearsSinceGenesis,
    initialInflation: inflationGovernor.initial,
    terminalInflation: inflationGovernor.terminal,
    taperRate: inflationGovernor.taper
  };
}

Примечания

1. Возвращает параметры, управляющие инфляцией в сети Solana
2. Инфляция снижается со временем согласно скорости уменьшения
3. Инфляция фонда отделена от инфляции валидаторов
4. Ответ приходит немедленно, так как читается из текущего состояния
5. Эти параметры устанавливаются управлением и могут изменяться

​

Рекомендации

1. Используйте этот метод для понимания расписания инфляции сети
2. Кэшируйте результаты там, где это уместно, для снижения нагрузки на RPC
3. Учитывайте влияние инфляции на вознаграждения за стейкинг
4. Отслеживайте изменения в параметрах инфляции
5. Используйте совместно с другими методами, связанными с инфляцией

Сценарии использования

1. Анализ инфляции
   interface InflationMetrics {
     currentInflation: number;
     yearsSinceGenesis: number;
     initialInflation: number;
     terminalInflation: number;
     taperRate: number;
     foundationPercentage: number;
     foundationTerm: number;
     validatorInflation: number;
     foundationInflation: number;
   }
   
   async function analyzeInflation(): Promise<InflationMetrics> {
     const inflationGovernor = await connection.getInflationGovernor();
     const epochInfo = await connection.getEpochInfo();
     
     const yearsSinceGenesis = epochInfo.absoluteSlot / (432000 * 365);
     const currentInflation = Math.max(
       inflationGovernor.terminal,
       inflationGovernor.initial - (inflationGovernor.taper * yearsSinceGenesis)
     );
     
     const foundationInflation = yearsSinceGenesis < inflationGovernor.foundationTerm
       ? currentInflation * inflationGovernor.foundation
       : 0;
     
     return {
       currentInflation,
       yearsSinceGenesis,
       initialInflation: inflationGovernor.initial,
       terminalInflation: inflationGovernor.terminal,
       taperRate: inflationGovernor.taper,
       foundationPercentage: inflationGovernor.foundation,
       foundationTerm: inflationGovernor.foundationTerm,
       validatorInflation: currentInflation - foundationInflation,
       foundationInflation
     };
   }
   
2. Прогнозирование вознаграждений за стейкинг
   interface StakingProjection {
     currentAPY: number;
     futureAPY: number[];
     years: number[];
   }
   
   async function projectStakingRewards(
     totalStaked: number,
     totalSupply: number,
     years: number = 10
   ): Promise<StakingProjection> {
     const inflationGovernor = await connection.getInflationGovernor();
     const epochInfo = await connection.getEpochInfo();
     
     const currentYear = epochInfo.absoluteSlot / (432000 * 365);
     const yearsArray = Array.from({ length: years }, (_, i) => i);
     
     const futureAPY = yearsArray.map(year => {
       const inflation = Math.max(
         inflationGovernor.terminal,
         inflationGovernor.initial - (inflationGovernor.taper * (currentYear + year))
       );
       
       const foundationInflation = (currentYear + year) < inflationGovernor.foundationTerm
         ? inflation * inflationGovernor.foundation
         : 0;
       
       const validatorInflation = inflation - foundationInflation;
       return (validatorInflation * totalSupply) / totalStaked;
     });
     
     return {
       currentAPY: futureAPY[0],
       futureAPY,
       years: yearsArray
     };
   }
   
3. Мониторинг инфляции
   interface InflationAlert {
     type: 'high' | 'low' | 'change';
     message: string;
     currentInflation: number;
     expectedInflation: number;
     difference: number;
   }
   
   async function monitorInflation(
     threshold: number = 0.01
   ): Promise<InflationAlert[]> {
     const inflationGovernor = await connection.getInflationGovernor();
     const epochInfo = await connection.getEpochInfo();
     
     const yearsSinceGenesis = epochInfo.absoluteSlot / (432000 * 365);
     const expectedInflation = Math.max(
       inflationGovernor.terminal,
       inflationGovernor.initial - (inflationGovernor.taper * yearsSinceGenesis)
     );
     
     const currentInflation = await connection.getInflationRate();
     const difference = Math.abs(currentInflation - expectedInflation);
     
     const alerts: InflationAlert[] = [];
     
     if (difference > threshold) {
       alerts.push({
         type: 'change',
         message: `Inflation differs from expected by ${difference.toFixed(4)}`,
         currentInflation,
         expectedInflation,
         difference
       });
     }
     
     if (currentInflation > inflationGovernor.initial) {
       alerts.push({
         type: 'high',
         message: `Inflation is above initial rate`,
