为什么我看不到去中心化平台的许多优势
老实说，从我的角度来看，我并不认为去中心化平台有太多优势，因为我的个人数据在全球的节点上以公开的方式分散存储。在这篇文章中，我想指出一些关于当前链上世界的关键点和问题，你应该了解。
例如，让我们看看比特币区块链：
1) 区块大小限制：比特币区块链由于区块大小的限制，限制了每个区块可以容纳的数据量。
2) 存储成本高：在比特币区块链上存储数据成本高且有限，因为数据必须在所有节点上复制，并且区块链数据不断增长。
3) 速度慢：对于比特币来说，新块大约每10分钟被挖掘一次，交易的完全确认可能需要长达一个小时。
4) 缺乏隐私：在比特币、以太坊和索拉纳等公共区块链上，所有交易、金额和钱包余额都是可见的。
5) 智能合约有限：比特币没有或仅有有限的图灵完备智能合约。
6) 不在你的控制之下：虽然没有集中“第三方”，但控制权分散在你无法控制的节点和验证者之间。
7) 不可变性：链上数据无法删除；它会永远存在。
8) 升级和交付困难：重大变更通常需要硬分叉。
9) 节点和验证者有自己的“家”：其中一些可能受到监管甚至被关闭，这正是去中心化比中心化更强大的原因——网络仍然在运行。
工程师们正在努力解决这些问题，但大多数问题以某种方式影响几乎所有区块链。
在Hashmate，我做出了不同的决策：
1) 设计隐私：你不必向服务暴露你的信息，服务也从不要求个人数据。
2) 最小知识原则：平台对你的了解尽可能少。实际上，它只有你提供的信息。
3) 你的数据就是你的数据：一旦你删除某些内容，它就永远消失。在链上？没错，由于区块链的不可变性，你的数据会永远保留在那里。
4) 集中式去中心化：如今，几乎所有中型项目和平台在底层都是分布式的。我指的是负载均衡器、副本、计算和存储节点。区别在于谁控制这基础设施——是随机的人还是公司。因此，这更多的是关于所有权而非隐私。
5) 轻松升级：对基础设施的集中控制使得变更和升级的交付变得简单。
6) 公开内容：大多数内容本质上是公开的。
为了澄清，我并不是反对去中心化或类似的观点。我的主要观点是，我们也可以构建真正集中且完全私密的平台——只是大多数现有的平台缺乏许多基本的隐私功能。
总结一下：
- 去中心化并不意味着隐私。
- 去中心化意味着分布。
- 隐私是关于设计，而不是分布。
- 公共去中心化意味着你的历史和交易是可见的、可追踪的，并且永远保留在公共领域。
- 我唯一能说的好处是，去中心化可能意味着所有权——但你的数据分散在你无法控制的节点上。
- 在链上仍然是昂贵的。

Honestly, from my point of view, I don’t see many advantages in decentralized platforms, where my personal data is distributed across nodes worldwide in public. In this post, I would like to note some key points about the current landscape and problems in the on-chain world that you should know.<p>For example, let's take a look at the Bitcoin blockchain:<p>1) Block size limitations: The Bitcoin blockchain is limited due to its block size, which restricts how much data can fit in a block.<p>2) Expensive storage: Storing data on the Bitcoin blockchain is expensive and limited because it must be replicated across all nodes, and blockchain data constantly grows.<p>3) Slowness: For Bitcoin, a new block is mined approximately every 10 minutes, and full confirmation of transactions can take up to an hour.<p>4) Lack of privacy: On public blockchains like Bitcoin, Ethereum, and Solana, all transactions, amounts, and wallet balances are visible.<p>5) Limited smart contracts: Bitcoin doesn't have, or has limited, Turing-complete smart contracts.<p>6) Out of your control: While there’s no centralized “third party,” control is distributed among nodes and validators outside your control.<p>7) Immutability: On-chain data cannot be deleted; it stays forever there.<p>8) Hard to upgrade and deliver: Significant changes usually require a hard fork.<p>9) Nodes and validators have their homes: Some of them could be regulated or even shut down, that’s exactly what makes decentralization stronger than centralization — the network keeps running.<p>Engineers are trying to solve these problems, but most of them affect nearly every blockchain in one way or another.<p>In Hashmate, I made different decisions:<p>1) Privacy by design: You don’t have to expose your information to the service, and the service never asks for personal data.<p>2) Principle of minimal knowledge: The platform knows as little about you as possible. In fact, it has only what you provide.<p>3) Your data means your data: Once you delete something, it’s gone forever. On-chain? Right, your data stays there forever, due to the immutable nature of blockchains.<p>4) Centralized decentralization: Nowadays, practically all mid-size projects and platforms are distributed under the hood. I mean load balancers, replicas, computational and storage nodes. The difference is who controls this infrastructure — random people or a company. So, it’s more about Ownership than Privacy.<p>5) Easy upgrades: Centralized control over infrastructure allows easy delivery of changes and upgrades.<p>6) Public content: Most content is public by its nature.<p>Just to be clear, I’m not against decentralization or anything like that.
My main point is that we can build truly centralized and fully private platforms as well — it’s just that most existing ones lack many essential core privacy features.<p>TO SUM THINGS UP:<p>- Decentralization doesn’t mean Privacy.<p>- Decentralization means Distribution.<p>- Privacy is about design, not Distribution.<p>- Public decentralization means your history and transactions are visible, trackable, and stay there forever in public.<p>- Just one good thing I could really say is that decentralization could mean Ownership — but your data is spread across nodes that you don’t control.<p>- Being on-chain is still expensive.
