Simulating a Decentralized Lightning Network with 500,000 payments, 0.01% fee per hub and 10 Million Users: 100% success (99.9986%)

I repeated Diane Reynolds' simulation, as described here, using her program. The only change I made was that instead of having "11 different fee policies evenly distributed among users", each node simply asks for 0.01% fee (= value x 0.0001) to route a transaction. Some of the 11 fee policies were quite complicated, like "trying to make channels more balanced".

Here are the main results:

Payments attempted: 500,000

Fee as a percentage of the payment 0.175

Routing failed: 7

Routing failed for bigpayments: 3

Routing failed for midsizedpayments: 1

Routing failed for micropayments: 3

Average lengths of routes: 17.5

So the payment failed for only 0.0014% of the payments. Note that for the last 100,000 payments, routing failed only once (1 midsizedpayment) and from 100,000 to 500,000 only 3 times (1 big, 1 midsize, 1 micro). The average total fee for a payment makes sense, as 0.01% x 17.5 hubs = 0.175% total fee. I didn't realize the program stopped after 500,000 payments and will now try to run it for more payments.

No, Bitcoin is not controlled by a small group of investors and miners (A rebuttal to the TechSpot article)

I write this primarily in response to the TechSpot article from yesterday ( r/technology mods told me they only allow “ mainstream articles with editorial oversight and fact-checking ” so I'm sharing this here). But I’d also like to take this opportunity to write about Bitcoin more broadly as someone who has been following it for more than a decade and I’ll try to do so without complicating the conversation for anyone unfamiliar with Bitcoin. The TechSpot article cites a non-peer-reviewed National Bureau of Economic Research (NBER) working paper from Igor Makarov and Antoinette Schoar. NBER claims to be non-partisan but it is a private NPO funded by the likes of Bill Gates foundation . The chairman of NBER, Karen Horn, is a former president of the Federal Reserve Bank of Cleveland and Head of Int...

Day 9: I will post this guide regularly until available solutions like SegWit, order batching, and Lightning payment channels are mass adopted, the mempool is empty once again, and tx fees are low. Have you done your part?

BACKGROUND Segregated Witness (SegWit) was activated on the Bitcoin network August 24 2017 as a soft fork that is backward compatible with previous bitcoin transactions ( Understanding Segregated Witness ). Since that time wallets and exchanges have been slow to deploy SegWit, and the majority of users have not made the switch themselves. On Dec 18 2017 Subhan Nadeem has pointed out that: If every transaction in the Bitcoin network was a SegWit transaction today, blocks would contain up to 8,000 transactions, and the 138,000 unconfirmed transaction backlog would disappear instantly. Transaction fees would be almost non-existent once again . Mass SegWit use alone could empty the mempool, result in blocks that are not completely full, and make it possible to include transactions with $0 fee once again. On Jan 11 2018 when BTC sends went offline at Coinbase the mempool began to rapidly empty. Later in the day when service was restored there was a sharp spike up in the mempool . Subse...
