让我详细解释Sonic区块链网络的Live Pruning算法机制。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;

namespace Sonic.Blockchain.Pruning
{
   
   
    public class LivePruningAlgorithm
    {
   
   
        private readonly IPruningStrategy _strategy;
        private readonly IBlockchainState _state;

        public LivePruningAlgorithm(IPruningStrategy strategy, IBlockchainState state)
        {
   
   
            _strategy = strategy;
            _state = state;
        }

        /// <summary>
        /// 执行实时修剪操作
        /// </summary>
        public async Task<PruningResult> ExecutePruningAsync(PruningContext context)
        {
   
   
            var result = new PruningResult();
            
            try
            {
   
   
                // 1. 获取当前状态快照
                var snapshot = await _state.GetSnapshotAsync();
                
                // 2. 计算修剪边界
                var boundary = _strategy.CalculatePruningBoundary(snapshot, context);
                
                // 3. 分析UTXO集合
                var utxoSet = await _state.GetUtxoSetAsync();
                var spentOutputs = await AnalyzeSpentOutputs(utxoSet, boundary);
                
                // 4. 执行分层修剪
                await ExecuteLayeredPruning(boundary, spentOutputs);
                
                // 5. 更新索引和元数据
