1/segwitx2 won’t cause a drop in full nodes numbers. It’s economically sustainable for worldwide average users who want to run a full node
2/..and will be more sustainable as technology improves. There are no serious centralization issues with Silbert accord
3/segwit2x is no bowing to miners’ blackmail, just the anticipation of something needed (2mb HF) as stated in Core roadmap:
4/”advances in technology will reduce the risk and therefore controversy around moderate block size increase proposals”..
5/…we “will be able to move forward w/ these increases when..their risks widely acceptable relative to the risks of not deploying them”
6/Core dev Matt Corallo says about segwit2x he is “totally supportive of the stated goals” see here
7/After LN release, we need low onchain fees if we want it to be decentralized, 2mb block increase might be helpful. I exemplify:
LN.1/Alice receives a 2btc payment from Mallory, intermediary is Bob. Last commitment tx in Alice-Bob channel has balance: A,B(5,5).
LN.2/in A-B channel a new commitment created: A,B(7,3). Alice can broadcast onchain only if she knows Image from Mallory.
LN.3/a new commitment is created in channel B-M, previous balance B,M(10,5) now (12,3)
LN.4/Mallory gives Image to Alice. She broadcast onchain. Mallory broadcast the past commitment B,M(10,5) onchain, at her own risk
LN.5/Bob is distracted or for whatever reason can’t broadcast the Breach Remedy tx (15,0). Mallory stole Bob money.
LN.6/Bob has a risk to act as intermediary. The higher the risk, the higher the fee.
LN.7/Indeed, LN will have low fee, because it will be software, not Bob, that broadcasts Breach Remedy tx
LN.8/But when will be released nice GUI safe (or SPV smartphone) software to allow avereage users for LN payments? Months? Years?
LN.9/When LN will be ready, if average users have to pay very high fee for onchain tx, there won’t be a very capillar network
LN.10/Rather, only main wallet providers will act as intermediaries. When a user deposits btc in the wallet, he will already open a channel
LN.11/the wallet provider will soon have network advantage. Users prefer a unique intermediary rather than open new channels with onchain tx
LN.12/economy of scale: a few wallet providers will own the quasi-totality of intermediary channels. Oligopoly. Offchain fees increase
LN.13/attacking the wallet provider (the hub) may result in a slowdown of transactions.
LN.14/an attack may also prevent the hub from broadcasting Breach Remedy tx: funds may be stolen?
LN.15/LN is the only way to scale, but needs to be decentralized: blocksize-increase guarantees lower fee onchain and offchain..
LN.16/…such that people can open new channels without high costs: the way to offhchain intermediaries decentralization
8/I think scaling debate is more a matter of ideology than stakeholders interests. But if we want to be mischievous:
9/self interested miners are for bigblock, because onchain fees. Self interested developers are for small block, because offchain fees
10/The cost and benefits of the onchain vs offchain tx actually compete, and miners/devs have interests in lessening competition
11/best scenario for users: sw active and blocksize increasing as technology improves, on condition that average users able to run fullnodes
12/Be pragmatic and less ideological. The only way is to concede 2mb. UASF not viable unless it reaches 51% hashrate
13/UASF is a SF chain split, sgwit2x a HF with much less probabiliy to cause a split
14/There is no Core support to UASF bip 148 see here
15/#UASF: chain split without miners, without developers, without other players like exchanges. And without users. Are u serious?
16/#UASF is more #TNASF than else (Twitter Noise Activated Soft Fork)
17/be very optimistic, UASF chain reaches 20% hashrate; this could be the scenario with parts of the total hashrate mining distribution:
18/non-uasf chain 51%, 20% uasf, 21% non-uasf miners orphaning blocks in UASF chain (if just a part of segwit2x miners hashrate coordinates)
19/If non-uasf miners are really able to coordinate, they can also easily manage a 33% uasf attack (more details if u ask).
20/if the scenario gets more complicated, with counter-uasf hard (or soft) forks, the chain splits will be so harsh..
21/…that you’d be better off moving to Litecoin : )
