另一个办法是在开始要求交易费之前，减少每个区块允许的免费交易数量。每个区块中，节点只会接纳一定 KB 数量的免费交易，超过后就开始要求至少 0.01 的交易费。
这个阈值或许应该比目前更低。
我不认为这个阈值在任何时候都应该是 0。我们应当始终允许至少一些免费交易。

Another option is to reduce the number of free transactions allowed per block before transaction fees are required. Nodes only take so many KB of free transactions per block before they start requiring at least 0.01 transaction fee.
The threshold should probably be lower than it currently is.
I don't think the threshold should ever be 0. We should always allow at least some free transactions.
