Detailed notes

## Background Published on YouTube by Decentralized Thought on December 15, 2017, this video serves as the finalized edition of the creator's earlier work, "The truth about the lightning network." According to the video description, it is intended as a foundational menu covering upcoming topics such as censorship on r/theymos, Blockstream's ties to banking institutions, and developer governance disputes.

## TL;DR The video argues that Bitcoin's original vision as cheap, decentralized, peer-to-peer electronic cash has been compromised by an artificial 1-megabyte block size limit that triggers exorbitant fees and severe network delays. It examines the mechanics of the second-layer Lightning Network, demonstrating how liquidity bottlenecks and multi-hop failures will inevitably force users into centralized, well-capitalized routing hubs subject to standard banking regulations like KYC and AML. The author contends that Blockstream deliberately crippled on-chain scaling to monetize proprietary sidechains and hub services, satisfying its corporate and banking investors by recreating the legacy banking system on top of Bitcoin.

## Atmosphere & style The presentation carries a sharp, disillusioned, and investigative tone that channels the bitter frustration of early crypto adopters watching a grassroots monetary revolution be subverted from within. The narration is measured, methodical, and cynical, peeling back technical abstractions to reveal cold financial incentives. Watching it feels like a sobering counter-narrative to 2017 bull-market euphoria, shifting from the stinging reality of paying extortionate transaction fees to a somber, calculated expose of corporate capture.

## Detailed walkthrough ### [00:01](https://www.youtube.com/watch?v=UYHFrf5ci_g&t=1s) The Broken Promise: From Cheap Peer-to-Peer Cash to Exorbitant Fees

A few years ago, Bitcoin presented itself as a monetary revolution built to obsolete the legacy banking industry. It promised permissionless, decentralized, peer-to-peer electronic cash that could not be confiscated, allowing anyone on Earth to transfer funds in seconds for less than a single penny. Many prospective users hesitated when the token reached $100, assuming it would inevitably fail and choosing to wait on the sidelines. However, after watching the price explode across mainstream news to $15,000, those same onlookers felt immediate regret and rushed into the market hoping they were still getting in on the ground floor.

The practical reality of interacting with the network quickly shattered those expectations. After waiting five hours for a single confirmation, an investor transferring a modest $30 purchase would find half their money missing before it even reached their personal custody. As the narrator bitterly observes, “Turns out that your small investment of thirty dollars, fifteen dollars went towards the transfer fee to put it in your wallet.” This breakdown in basic utility stems directly from the hard-coded 1-megabyte block size limit, which restricts throughput to only a handful of transactions per second. When transaction volume outpaces capacity, users are forced into an auction where only the highest bidders get prioritized. By December 12, 2017, this dynamic drove the average daily transaction fee to a staggering $24.40, a structural bottleneck that guarantees the network becomes increasingly unusable as broader adoption takes hold.

- Original promise: decentralized, permissionless, fast transactions costing fractions of a cent. - Early price hesitation: $100; subsequent bull market peak: $15,000. - Onboarding friction: a $30 initial buy loses $15 to network fees alongside 5-hour confirmation delays. - December 12, 2017 metric: average transaction fee hit $24.40 under the 1 MB block limit.

[01:45](https://www.youtube.com/watch?v=UYHFrf5ci_g&t=105s) Off-Chain Routing and the Realities of the Lightning Network

Instead of increasing the base block size to accommodate growing demand, the Core development team opted to pursue a secondary layer dubbed the Lightning Network. Designed to deliver instantaneous settlement and negligible fees, the system relies on opening two-party payment channels backed by multi-signature addresses. To initiate a channel, both participants lock up a predetermined quantity of coins—for example, one Bitcoin each for a total capacity of two Bitcoins. Once secured on-chain, both parties can transfer funds back and forth indefinitely without incurring network fees, provided both cryptographically sign every state update. As the narrator clarifies regarding this mechanism, “We're essentially trading for the rights of the coin, offchain, similar to an IOU.” The actual base-layer Bitcoin remains unmoved until one of the parties decides to close the channel and broadcast the final balance to the blockchain.

```mermaid flowchart TD accTitle: Lightning Network Routing Dynamics accDescr: Flowchart contrasting an idealized multi-hop payment with liquidity failure and merchant hub routing.

subgraph DirectChannel["Bi-Directional Channel Setup"] A["User A"] <-->|"Locked in 2-of-2 Multisig (2 BTC Total Capacity)"| B["User B"] end

subgraph LiquidityIssue["Multi-Hop Liquidity Failure"] U["Payer"] -->|"Wants to send 1 BTC"| C["Channel 1 (Balance: 2 BTC)"] C --> S["Sam (Intermediary)"] S -.->|"Channel Capacity: 0.5 BTC (Route Fails: Insufficient Funds)"| R["Bob (Recipient)"] end

subgraph HubRouting["Merchant / Hub Routing"] PayerNode["Payer"] -->|"Route Payment"| Merchant["Local Pizza Shop (High Liquidity)"] Merchant -->|"Settle Payment"| BobNode["Bob"] end ```

The model becomes far more complex when transacting with someone outside an existing direct channel. Under the idealized vision of the network, if a user wants to pay Bob 1 Bitcoin, the payment can hop through an intermediary like cousin Sam, who already maintains an active channel with Bob, paying microscopic routing fees along the chain. However, this design breaks down due to strict channel capacity constraints. If Sam’s channel only holds 0.5 Bitcoin, the 1 Bitcoin transaction cannot pass through, forcing the protocol to locate another path. While this can occasionally be resolved if both users happen to frequent the same well-funded merchant—such as a local pizza parlor with substantial balance reserves—the system's baseline requirement remains unforgiving.

- Channel mechanics: requires locking funds into a 2-of-2 multisig address; on-chain base fees are incurred only during channel opening and closing. - Routing restriction: payments cannot exceed the balance capacity of any single intermediate channel along the route. - Ideal design: peer-to-peer relay through acquaintances; practical breakdown: failed hops caused by insufficient intermediary liquidity.

[04:00](https://www.youtube.com/watch?v=UYHFrf5ci_g&t=240s) The Emergence of Lightning Hubs and the Return of Banking

Because users cannot route payments without sufficient capital along the path, maintaining ad-hoc peer channels creates significant logistical friction. To transact reliably, an individual must preload each individual channel with the upper limit of their expected expenditures. Consequently, economic incentives heavily favor routing through a single, well-connected intermediary with massive capital reserves. This structural necessity inevitably gives birth to centralized Lightning hubs—heavily capitalized nodes capable of handling countless open channels with abundant liquidity, thereby slashing transaction failure rates and hop counts.

```mermaid flowchart LR accTitle: Centralized Lightning Hub Architecture accDescr: Diagram demonstrating how individual end users connect to a centralized, regulated Lightning Hub rather than direct peers.

subgraph EndUsers["End Users"] U1["User 1"] U2["User 2"] U3["User 3"] end

subgraph CoreHub["Regulated Lightning Hub"] Hub["Central Node / Financial Institution - Massive Liquidity Pools - KYC/AML Compliance - Fraud Detection / Watchtowers"] end

subgraph Destinations["Recipients / Merchants"] M1["Merchant A"] M2["Merchant B"] end

U1 --> Hub U2 --> Hub U3 --> Hub Hub --> M1 Hub --> M2 ```

These centralized hubs introduce the very regulatory and custodial burdens Bitcoin originally eliminated. Because hubs facilitate and settle third-party value transfers, regulators will classify them as financial institutions subject to standard Know Your Customer (KYC) and Anti-Money Laundering (AML) enforcement. Furthermore, unlike the native blockchain, Lightning introduces counterparty theft risks: if an unscrupulous channel partner broadcasts a previous, more favorable channel state, they can drain funds unless the victim constantly monitors the chain. To mitigate this risk, users must either maintain an uninterrupted full node online 24/7 or outsource monitoring to dedicated third-party fraud departments and watchtowers. Summarizing the fundamental irony of this architecture, the narrator argues:

> “The banks aren't fighting Bitcoin, because Bitcoin will be the new banking system.”

- Financial classification: large routing hubs operate as third-party settlement entities bound by AML and KYC reporting. - Fraud risk: broadcasting outdated channel states allows balance theft unless caught within a dispute window. - Operational burden: requires 24/7 uptime for local full nodes or recurring payments to third-party monitoring services. - Structural shift: replaces decentralized settlement with the equivalent of commercial checking accounts and regulated intermediaries.

[06:26](https://www.youtube.com/watch?v=UYHFrf5ci_g&t=386s) The Blockstream Takeover and the Monetization of Scarcity

The technical bottleneck suffocating Bitcoin was neither accidental nor unavoidable. The original 1-megabyte block size limit was implemented solely as a temporary anti-spam safeguard by Satoshi Nakamoto, intended to be raised incrementally as transaction volumes approached the ceiling. When Satoshi departed the project in 2010, he left clear instructions on how to adjust this limit and handed primary stewardship to Gavin Andresen. Soon after, external corporate and institutional capital penetrated the ecosystem, leading to the formation of Blockstream. A substantial contingent of Core developers became direct employees of or contractors for Blockstream, creating an institutional faction steadfastly opposed to raising the base block size.

Through coordinated administrative control, social media censorship, and developer purges, Blockstream consolidated governance over Bitcoin's reference repository, driving out alternative developers who advocated for on-chain scaling. The narrator emphasizes that keeping the base layer broken serves an explicit commercial agenda:

> “This model is far more profitable if Bitcoin doesn't work properly.”

Blockstream’s corporate roadmap depends directly on selling proprietary sidechains, hardware, and recurring subscription services to enterprises seeking refuge from mainchain congestion. If on-chain transactions remained cheap, frictionless, and fast, businesses would have zero incentive to purchase Blockstream’s commercial alternatives. High fees and backlogged mempools ensure demand for custodial sidechains and centralized Lightning hubs, providing the revenue stream required to pay back the $74 million invested by corporate backers and major banking institutions. Rather than emancipating global commerce from financial gatekeepers, the protocol's core utility has been deliberately crippled for control, leaving speculative price hype as the sole distraction.

- Historical baseline: 1 MB limit was an emergency spam measure left behind by Satoshi Nakamoto alongside instructions for lifting it. - Governance transition: Satoshi passed leadership to Gavin Andresen; corporate influence culminated in Blockstream absorbing core contributors. - Ecosystem fallout: multi-day confirmation queues, merchant abandonment, and censorship-driven developer expulsions. - Commercial conflict: Blockstream secured $74 million from venture and banking entities, monetizing the artificial bottleneck via custom sidechain software, monthly fees, and proprietary hardware.

中文简报

Blockstream限制比特币吞吐量以将闪电网络货币化 Blockstream维持比特币1兆字节的区块大小限制以人为制造链上拥堵，迫使交易进入受监管的闪电网络中心，从而变相重建传统银行系统。该视频认为，比特币作为廉价、去中心化点对点电子现金的最初愿景，已被人为设置的1兆字节区块大小限制所损害，该限制引发了过高的手续费和严重的网络延迟。视频审视了二层闪电网络的运行机制，展示了流动性瓶颈和多跳路由失败将如何不可避免地迫使用户依赖中心化、资金充裕且受KYC和AML等标准银行法规监管的路由中心。作者主张，Blockstream蓄意削弱链上扩容能力，旨在将其专有的侧链和网络中心服务货币化，并通过在比特币之上重建传统银行系统来满足其企业和银行投资者的利益。比特币的基础层实用性受到1兆字节区块限制的严重削弱，导致2017年12月12日的平均交易手续费飙升至24.40美元，使小额交易在经济上不再可行。 (0:01) 闪电网络通过多重签名支付通道将交易转移至链下，其本质上类似于借据（IOU），仅在通道开启或关闭时才在区块链上结算。 (1:45) 闪电网络多跳路由中的流动性瓶颈，自然会促成资金雄厚的中心化路由中心的形成，而这些中心将面临KYC和AML等标准银行法规的监管。 (4:00) 批评人士认为，Blockstream故意维持基础层拥堵，是为了将侧链、硬件以及收费型二层基础设施商业化，以偿还7400万美元的风投和银行资本。 (6:26)

Reading summary

The presentation argues that Bitcoin's original utility as low-cost peer-to-peer cash was deliberately undermined by maintaining artificial base-layer block limits. According to the publisher, diverting transaction volume onto the Lightning Network recreates conventional, regulated banking intermediaries to monetize network congestion for institutional investors. On-Chain Bottlenecks and Eroding Cash Utility (0:01) Bitcoin originally promised permissionless, instant electronic payments costing fractions of a cent, presenting an alternative to legacy financial institutions. However, retaining the hard-coded 1-megabyte block size limit restricted throughput to a handful of transactions per second, creating an auction where users had to outbid one another to secure transaction confirmations. By December 12, 2017, surging usage drove average network fees to $24.40 alongside five-hour delays, rendering small transfers economically unviable, such as an investor losing $15 in network fees to move a $30 purchase into self-custody. Channel Limitations and Multi-Hop Liquidity Failures (1:45) Rather than increasing base-layer block capacity, Core developers promoted the Lightning Network, an off-chain layer relying on 2-of-2 multi-signature channels where participants exchange cryptographic state updates akin to IOUs. On-chain transaction fees are only incurred when opening or closing channels, leaving coins on the base chain unmoved during channel operation. However, transacting outside direct two-party channels requires routing payments across intermediary nodes, which fail whenever any channel along the chosen route lacks sufficient locked capital to cover the payment amount. Emergence of Regulated Hubs and Custodial Friction (4:00) Because ad-hoc peer routing suffers from severe liquidity constraints, economic incentives favor routing transactions through massive, heavily capitalized nodes. The narrator contends that these centralized Lightning hubs inevitably recreate the conventional banking system, functioning as commercial settlement intermediaries. Consequently, large hubs will face standard financial compliance burdens, such as Know Your Customer (KYC) and Anti-Money Laundering (AML) enforcement. Furthermore, guarding against counterparty fraud from outdated channel state broadcasts requires participants to run nodes 24/7 or outsource monitoring to third-party watchtowers. Corporate Capture and the Monetization of Scarcity (6:26) The source contends that the 1-megabyte limit was merely an emergency anti-spam safeguard that Satoshi Nakamoto intended to raise, leaving explicit instructions to do so before entrusting stewardship to Gavin Andresen. Instead, institutional capital entered the ecosystem through Blockstream, which hired prominent Core contributors, opposed block size increases, and consolidated control over repository governance. The narrator asserts that Blockstream intentionally preserved the base layer's bottleneck to protect its commercial business model, using artificial congestion to drive enterprise demand for its proprietary sidechains, hardware, and paid services to repay $74 million in venture and banking capital. The publisher concludes that Bitcoin has abandoned its monetary revolution; instead of obsoleting traditional finance, technical gatekeeping and corporate incentives have redesigned the protocol into an infrastructure that banks can operate, using speculative price appreciation to obscure lost transactional utility.

精炼阅读摘要

节目《Decentralized Thought》指出，比特币最初作为廉价、抗审查点对点现金的愿景已被破坏；开发团队拒绝提高基础区块上限，转而推行闪电网络，这一架构不仅因流动性瓶颈催生了高度中心化且受监管的金融中介，也符合商业机构通过人为维持主链拥堵来变现专有解决方案的利益诉求。基础区块限制与点对点现金承诺的破灭 (0:01) 比特币最初设想为一种无需许可、去中心化且交易成本不足一分钱的电子现金。然而，随着币价从早期的100美元攀升至15,000美元的高位，涌入的新用户遭遇了严重的网络效能危机。由于主链硬编码了1 MB的区块大小上限，网络吞吐量被限制在每秒极少数交易，导致交易池发生竞价拍卖。例如，普通投资者转账一笔30美元的资产，不仅需要等待长达5小时的确认，还会被扣除高达15美元的网络手续费；至2017年12月12日，全网平均交易费用更是攀升至24.40美元。节目指出，这种结构性瓶颈直接导致比特币丧失了作为日常点对点货币的基本实用价值。闪电网络链下路由及其流动性瓶颈 (1:45) 面对链上拥堵，Core开发团队选择通过二层协议闪电网络（Lightning Network）进行扩容。该方案要求双方在链上建立基于2-of-2多重签名地址的支付通道并锁定资金，随后在链下以类似借条（IOU）的形式通过加密状态更新进行无限次结算，仅在开启和关闭通道时向主链支付矿工费。然而，在脱离直接通道的多跳支付场景中，该模型面临严苛的通道容量限制。例如，若发起方计划转账1个比特币，但路由路径中的中继通道仅有0.5个比特币的容量，交易便会因流动性不足而失败。节目认为，这种硬性资金约束打破了依靠普通用户节点进行去中心化中继的理想设想。中心化结算枢纽与传统银行模式回归 (4:00) 由于个人通道难以支撑复杂的大额资金中继，经济激励必然驱使网络依赖拥有雄厚资本储备的超大型节点，由此催生出中心化的闪电网络枢纽。讲述者指出，这些承担大额多方清算功能的中心节点在法律上属于第三方结算实体，势必会受到监管机构强制执行的KYC（了解你的客户）与AML（反洗钱）法规约束。此外，闪电网络存在单方广播过时历史状态以盗窃资金的对手风险，迫使参与者必须维持全节点24小时不间断在线，或定期向第三方“守望塔”支付监测费用。讲述者主张，这种架构实际上再造了商业银行的活期账户体系与反欺诈部门，使比特币演变为受监管的传统银行业替代品。 Blockstream商业化与人为制造的稀缺 (6:26) 节目主张，1 MB的区块限制最初仅是中本聪为了防止垃圾交易设立的临时措施，其在2010年交接给Gavin Andresen时曾留下逐步调高上限的指导意见。然而，随着获得7400万美元风险投资与主流金融机构注资的Blockstream公司成立，大批Core开发者被其收编，支持链上扩容的开发者遭到边缘化与排挤。讲述者指控，Blockstream的核心商业模式依赖于向企业出售专有侧链技术、硬件与订阅服务；如果比特币主链交易廉价且畅通，企业将缺乏购买其二层商业产品的动力。通过人为压制主链容量，开发团队得以维系拥堵溢出需求，从而将技术瓶颈转化为商业利益。该节目总结认为，比特币在资本渗透与治理受控下已偏离最初的金融去中心化目标，演变出一套与现有银行业监管完全兼容的二层中介清算系统。需要注意的是，该观点反映了比特币扩容争论中批判Blockstream与二层路线的特定阵营立场，对于主链直接扩容可能对全节点去中心化硬件门槛带来的长期影响未予展开讨论。

截至视频录制的 2017 年 12 月 12 日，比特币单日平均交易手续费已飙升至 24.40 美元。 - 1 MB 的区块限制导致网络吞吐量极低，随着用户普及率提升，这一拥堵问题只会成倍恶化。 - 开发团队并未选择扩容，而是强推名为闪电网络（Lightning Network）的二层方案，标榜即时交易与超低费用。 --- ### [01:52](https://www.youtube.com/watch?v=UYHFrf5ci_g&t=112s) 闪电网络的运作机制与理想路由闪电网络的核心逻辑是“链下交易、最终结算”。举例来说，若两个人经常发生交易往来，他们可以共同出资建立一个通道（Channel）。双方各自向一个多重签名（multi-signature）地址存入 1 枚比特币，将总共 2 枚比特币暂时锁定在该地址中。在此之后，只要双方在每笔交易上共同签名，他们就可以在这 2 枚比特币的额度内无手续费、无限制地来回转账。 ```mermaid flowchart TD accTitle: 闪电网络点对点路由与通道资金限制 accDescr: 展示用户通过中间人向目标用户转账的过程，以及通道资金不足导致路由失败的场景。 subgraph ChannelFunding["链上锁定与通道建立"] A["用户 A (发起方)"] <-->|"锁定资金通道 (2 BTC)"| B["用户 B (中继方)"] end subgraph RoutingAttempt1["理想路由 (路径资金不足)"] B -.->|"通道仅有 0.5 BTC (转账 1 BTC 失败)"| S["表弟 Sam"] S -.->|"中继中断"| C["目标接收人 Bob"] end subgraph RoutingAttempt2["成功路由 (高流动性节点)"] A -->|"通过已有通道转账"| P["比萨店 (资金充足)"] P -->|"中继转账 1 BTC"| C end ``` 这种机制之所以不产生链上手续费，是因为真正的比特币自始至终没有发生链上移动，双方本质上是在链下交换比特币的所有权凭证，类似于借条（IOU）。只有当通道被关闭时，最终的账目才会提交到底层区块链进行最终结算，借条被兑现为真实的比特币。因此，高额的交易费用只在开启和关闭通道时发生。在跨节点交易的理想设想中，如果用户想向没有直接通道的 Bob 支付 1 枚比特币，网络会通过信任链路由：若用户与某人有通道，而该人的表弟 Sam 刚好与 Bob 建立了通道，资金就可以像击鼓传花一样逐级跳跃，用户只需向各级中继节点支付微不足道的过路费。然而，该系统存在严格的资金约束——通道必须预先存有足够的额度。若中继通道中仅有 0.5 枚比特币，这笔 1 枚比特币的交易就会直接失败，网络必须另寻通道。如果用户和 Bob 恰好都常去同一家拥有充裕比特币储备的比萨店消费，且双方都与该店建有通道，交易便能经由比萨店快速完成。 --- ### [04:00](https://www.youtube.com/watch?v=UYHFrf5ci_g&t=240s) 闪电网络枢纽的中心化与银行化异化尽管点对点路由听起来很美好，但闪电网络在机制上要求用户必须在开启通道时，提前充值该通道在未来消费周期内的支出上限资金。普通人不可能与成百上千的个人或商户分别建立通道并预存资金，因此最便捷的方案必然是只开启一个通道，连接到一个拥有海量资金、高度互联的大型中间节点。叙述者尖锐地指出，这种结构必然导致中心化的闪电网络枢纽（Lightning Hubs）自然诞生。闪电网络枢纽本质上是具备大量通道和庞大流动性资金的超级节点。连接到此类枢纽后，普通用户无需维护多个通道，无需担心对方余额不足，还能减少跳转跳数和中继费。然而，这种架构彻底颠覆了比特币的去中心化特性。矿工仅仅打包数据并不转移实质资产，但闪电枢纽直接经手大额资金流转，极有可能被法律界定为第三方结算机构（Third-Party Settlement Organizations），从而必须遵守严格的金融监管，包括了解你的客户（KYC）和反洗钱（AML）法规。此外，闪电网络引入了链上所没有的被盗风险：如果交易对手趁你不在线，向链上广播通道的旧状态，便有可能窃取通道内的资金。为了防止欺诈，用户必须自己运行全天候在线的比特币全节点来时刻监控网络，或者雇佣第三方监控服务。这样一来，闪电网络枢纽不仅需要应对监管与合规报告，需要巨量流动性以支撑各通道资金池，还需要设立全天候的反欺诈部门监控区块链防止盗窃，并在每笔中继交易中抽取手续费。叙述者讽刺道： > “The banks aren't fighting Bitcoin, because Bitcoin will be the new banking system.” 只要将闪电网络中的“开启通道”（open channel）换成“活期支票账户”（checking account），这套架构便与传统银行毫无二致。比特币最初诞生就是为了彻底消灭中间人、消除审查许可、消除交易撤销与高昂中介费用；然而现在的开发路径却故意将其系统破坏，让普通用户陷入两难——要么接受被剥夺自由、经由闪电网络银行体系中转，要么在主链上面临高达两位数甚至三位数的极度昂贵的手续费。 --- ### [06:26](https://www.youtube.com/watch?v=UYHFrf5ci_g&t=386s) 区块大小争议与 Blockstream 的商业收割比特币底层 1 MB 的区块容量并非不可突破的技术铁律，而是中本聪（Satoshi Nakamoto）在早期为了防止恶意垃圾交易而设置的临时防护措施。中本聪原本的设想是，一旦区块接近饱和，就应当及时上调大小。中本聪在 2010 年神秘离开发布的项目时，留下了如何调大区块大小的明确指引，并将代码维护权移交给了加文·安德烈森（Gavin Andresen）。然而随着中本聪的淡出，机构资本开始介入并渗透比特币的核心开发话语权，商业公司 Blockstream 应运而生。比特币核心开发团队中的大量成员逐渐被 Blockstream 招致麾下。当扩容节点到来时，正是这批为 Blockstream 效力的开发者极力反对提升区块大小。通过严厉的舆论审查、组织化攻击和舆论操纵，反对扩容的势力边缘化并驱逐了持有异见的开发者，牢牢掌控了比特币的开发主导权，导致交易费用呈指数级暴涨，确认时间从几分钟拉长到数天，致使大量线上商家因体验恶化而放弃支持比特币。 ```mermaid flowchart LR accTitle: Blockstream 商业利益与主链拥堵的关系 accDescr: 说明 Blockstream 限制主链区块大小以推销自身侧链方案并偿还资方投资的商业逻辑。 subgraph ArtificialCongestion["人为制造拥堵"] M1["坚决维持 1 MB 区块限制"] --> M2["主链交易费暴涨且延迟剧增"] M2 --> M3["迫使企业与用户寻求替代方案"] end subgraph CommercialMonetization["商业收割体系"] M3 --> B1["向企业出售侧链解决方案"] B1 --> B2["收取硬件销售费、月租费与交易抽成"] B2 --> B3["偿还资方与华尔街大行 7400 万美元投资"] end ``` 主链区块容量本可以在毫无中心化风险的情况下扩容多年，为寻找更完善的扩容技术留出充足时间，但这一方案被彻底阻死。其背后的商业逻辑在于：Blockstream 的核心盈利模式是向企业销售侧链（Sidechains）产品。他们向企业兜售定制化的比特币挂钩侧链，让商家免受主链高额费用的困扰，Blockstream 则借此收取交易分成、每月固定维护费以及运行侧链所需的定制硬件。若主链畅通且手续费极其低廉，根本不会有人购买其侧链产品。叙述者质问： > “If the fees are low and no one wants their sidechains, then, how will they pay the 74 million dollars back to the corporations and big bankers who have invested?” 叙述者指出，正是那些投资了 7,400 万美元的巨头企业与华尔街大银行，最终将从闪电网络枢纽的金融化中坐收渔利。一项原本旨在赋予全人类自由、稳定与主权的伟大技术，为了权力、控制权和商业利润而被肆意拆解瓦解。视频最后以讽刺的口吻总结道，即便底层技术已经被资本彻底腐蚀，狂热的投机者们依然在盲目庆祝资产“飞向月球”（going to the moon）。 ## Notable quotes > [04:00](https://www.youtube.com/watch?v=UYHFrf5ci_g&t=240s) The banks aren't fighting Bitcoin, because Bitcoin will be the new banking system. — Decentralized Thought ## Mentioned Bitcoin, Lightning Network, Blockstream, Decentralized Thought, Satoshi Nakamoto, Gavin Andresen, Jihan Wu, Roger Ver, r/theymos, Asicboost, Reddit, YouTube ## Video description This is the finished version of my original video "The truth about the lightning network" Treat this video as a menu to start at.

Original transcript

[0:01] Hey!, you!, you may have seen something about Bitcoin a few years back. [0:05] It sounded revolutionary. This was going to replace the banks. [0:11] It was permissionless decentralized peer-to-peer electronic cash. [0:16] No one can take it from you. You can send any amount for less than a penny fast. [0:21] But damn, the price was $100 and it would probably fail anyways so [0:27] you better play safe and see what happens. [0:30] Then you saw the price recently on the news, [0:33] $15,000 and immediately your stomach drop, because you realized that how rich you could have been, [0:41] but you blew it. [0:44] But you realize, that is still going up fast and if you invest now, [0:48] you're probably still in the ground floor. [0:51] When you finally get your Bitcoin, after waiting five hours for it to confirm, you realize that some is missing. [0:57] Turns out that your small investment of thirty dollars, [1:01] fifteen dollars went towards the transfer fee to put it in your wallet [1:06] This is what was going to change the world? [1:11] Let me fill you in on what happened, while you were gone. [1:15] Transaction fees have arisen because of the block size. [1:18] The block size is 1 megabyte currently. It only allows for a few transactions per second to take place. [1:23] Many more happen than this, so the people who pay the highest fee get to go first in line. [1:29] On december 12, 2017 at the time i'm recording this video, [1:33] the average transaction fee today [1:36] was twenty four dollars and forty cents [1:40] This problem only gets worse with time and his adoption spreads [1:45] Instead of raising the block size again [1:47] The development team has decided to go for a second layer called the Lightning Network. [1:52] It promises instant transactions, super low fees... and this is the basics of how it works: [1:59] Let's say me and you transact regularly so we open a channel for two Bitcoins. [2:05] I send a Bitcoin and you send a Bitcoin to a multi signature address [2:10] where it's temporarily locked away. [2:12] Now we are free to trade two Bitcoins back and forth with no fees, as long as we both sign each transaction. [2:18] This is because the actual Bitcoin was never moved. We're essentially trading for the rights of the coin, offchain, similar to an IOU. [2:26] When we close our channel it settles on the Blockchain. [2:29] Our IOUs are redeemed and we'll get our share of the real Bitcoin. [2:34] The only time the high transaction fee occurs, is when you open or close a channel to settle up. [2:41] You want to transact with somebody you don't have a direct channel open with. [2:45] Let's say you want to transact with Bob, and pay him 1 Bitcoin. [2:50] Bob does not currently have an open channel with you. And you don't want to have to pay the fees to open another channel. [2:55] It turns out that my first cousin Sam has an open channel with Bob. [3:00] You could send the payments through our channel [3:02] and use the channel I have opened with Sam and finally from Sam to Bob [3:07] paying me and Sam very small transaction fees for using our open channels. [3:10] This is ideally how, the network would work, [3:13] hopping from individual to individual until your transaction meets the intended recipient. [3:19] But it turns out that Sam isn't as fortunate as us [3:22] and our channel only as 0.5 Bitcoins deposited. [3:27] This won't work. There has to be enough loaded on each channel [3:31] along the way for it to be used. And the network must find another route. [3:36] Luckily it turns out that Bob and you both eat at the same pizza shop regularly enough that you both have open channels [3:43] The pizza shop has plenty of Bitcoin in its channel and is one less hop than the last example. [3:48] Bob gets paid, less fees for you, and the pizza shop gets a reward for providing a useful service [3:55] Everyone wins [3:57] Or so it would seem [4:00] A problem with the system is the requirement to preload every open channel you have ahead of time, [4:06] with what you assume will be the upper limit of your spending habits with that channel. [4:10] It's more convenient to have one open channel, and a large amount of Bitcoin, to a well connected party, [4:17] that consistently has more money than you so you can, always route through [4:22] This is why hubs will naturally occur. [4:25] A Lightning hub is a node with enough channels open and enough liquidity available. [4:29] By connecting them, you limit the amount of channels you need to personally open, [4:33] never have to worry about their balance, [4:36] and reduce the amount of hops and fees required to make transactions. [4:41] Unlike miners, who don't actually transfer value, [4:45] these hubs will likely be classified as third-party settlement organizations. [4:50] Being subject to heavy financial regulation laws, such as KYC and AML. [4:55] Also unlike on chain transactions there is a chance of theft in the system. [5:00] If another party attempts to broadcast a channel in an old state, [5:04] they can try to steal your Bitcoin if you can't catch them in time. [5:07] For this you will either need to run a full Bitcoin node, [5:10] that'll always be online to monitor the transactions yourself, [5:14] or hire a third-party service to do this on your behalf. [5:18] So, the Lightning hubs will require to be set up financial regulation and reporting laws [5:24] Require massive amounts of liquidity to keep multiple well-funded open channels. [5:29] Offer fraud departments to watch the blockchain constantly and prevent theft. [5:33] All while taking small fees for every transaction you route through them. [5:38] Does this system sound familiar? [5:41] Just replace the term "open channel" with "checking account" [5:47] These Lightning Network hubs, will be ran by the same financial institutions the Bitcoin was made to challenge. [5:53] The banks aren't fighting Bitcoin, because Bitcoin will be the new banking system. [6:00] Bitcoin needed no middleman, there was no fraud to detect, no permission to give, [6:05] no transaction to reverse, no fees to collect. [6:09] So it had to be broken to need them, and the worst part is you won't have a choice. [6:15] Either give up your freedom and use the Lightning Network, [6:18] or be subject to double or even triple digit ever-increasing fees, [6:23] for every move you make on the Blockchain. [6:26] The truth is, the 1 megabyte blocks restricting Bitcoin, are purposely kept there by the developers. [6:32] The absurdly high fees and long waits created demand for a solution [6:37] and the solution they give us is the banking industry. [6:40] The block size restriction, was placed as a temporary safeguard by Bitcoin's creator Satoshi Nakamoto. [6:47] As soon as the blocks were close to being full it was to be raised again. [6:52] Satoshi mysteriously left the project in 2010, [6:55] but before he did he left instructions on how to raise the block size, [6:59] and left Gavin Andreson in charge of the project. [7:02] Once Satoshi left institutional money started to make its way in and take control, [7:07] and a company Blockstream emerged. [7:10] Over time it happened that a large portion of the development team was part of or hired by this company, [7:15] and when it came time for another block size increase, [7:19] there was a portion of the developers that thought this was a bad idea. [7:22] This just so happened to be the same group of developers that work for Blockstream. [7:27] The story of how Blockstream took over is a long and strange one, and I'll have to cover it in another video, [7:33] but with massive amounts of censorship, organized attacks and manipulation, [7:38] Blockstream managed to take primary control over the development of Bitcoin [7:42] and force out any of the developers who opposed their choices, [7:45] and gave open arms to the ones whose opinions are aligned. [7:49] Ever since then, the fees have exponentially risen, [7:52] the confirmation times have have grown from minutes to hours, to days. [7:58] And the merchants are dropping support at a rapid rate. [8:01] The block size should have been raised long ago. [8:04] It could be raised for years without any risk of centralization, [8:07] giving us time to find other solutions. [8:09] But it won't happen, [8:11] because Blockstream states that they plan to turn a profit [8:14] by selling side chains to businesses, [8:17] allowing them to accept custom Bitcoin backchains [8:20] that aren't subject to Bitcoin's high fees, [8:23] taking small fees for every transaction, [8:25] fixed monthly fees from the businesses and selling the custom hardware needed to run them. [8:31] This model is far more profitable if Bitcoin doesn't work properly. [8:35] If the fees are low and no one wants their sidechains, [8:38] then, how will they pay the 74 million dollars back to the corporations and big bankers who have invested?, [8:45] the ones who benefit from the Lightning hubs. [8:48] This amazing technology designed to give freedom, [8:52] stability and power to the people around the world [8:54] has been ripped apart and destroyed for power, control, and profit. [9:02] But it's okay, because we're going to the moon...
