as HeReUK points out about the insecurity of not using the blckchain. if its not logged on the blockchain. then there are risks about trust and other issues. and yes LN has risks and trust issues too. its not trustless, not permissionless, not immutible.. oh and its not fungible.
When talking about the insecurity of not using the Bitcoin blockchain I was referring to your paper example and not LN.
LN is trustless, as you don't require any overseeing third party to ensure your money's safety. The only third party required, if you can call it that, is the Bitcoin blockchain.
LN is permissionless, as no one can exempt you on LN's protocol level from participating in the network.
LN is fungible, as you can use Satoshis as is (and potentially sub-Satoshi amounts); Upon settlement these amounts can be used like any other Satoshis on the network.
LN is not immutable, but its on-chain settlement is and trying to make illicit changes to a LN channel state gets heavily punished, making it a losing value proposition to any would-be attacker -- akin to how mining for block rewards is more profitable than attempting a double-spend attack.
Throwing a piece of paper with a private key on it is indeed permissionless, but neither trustless, nor fungible, nor immutable.
LN is trustless? seriously. stop reading the reddit promo material and actually do research.
1. you need to trust the other parties wont blackmail you for signatures.
2. theres a thing called autopilot that can send YOUR funds without your consent,
3. because its offchain people can alter their node to hack your funds and then at the end change it so you sign first (they gain the revoke) so if you then try to send a double signed tx to the blockchain. they can then revoke YOU. meaning YOU get punished.even if you were the victim of fund hacks.
have you even bothered to get an explanation as to the 'dont put too much coin into LN mainnet because you can lose it' (advice LN devs gave themselves)
LN is permissionless? wow please do some research. stop promoting something that you have not researched
1. you keep trying to make it out as if its just a channel opening handshake agreement thats required like tcp communications.. its not
2. LN does need permissions. for every payment. it is NOT a PUSH payment system. (learn push payments)
3. even if you run autopilot. making you the human not the permission giver.. the channel counterpart still needs your nodes permission (learn multisig)
4. you cant just say 'hi im A im paying D' and thats it. B, C and D need to agree on it if you are using the hop of 3 channels earlier example to get to D
5. as for no third party. again learn multisig. then learn why they want to bring schnorr into LN toallow fund managers to monitor the channel closes when people go offline(yes it will be a thing)
6. nodes CAN exempt you from participating.. after all.. those core fanboys have proven that already when they showed the meme of an LN node they named Rogerver being left exempt from the network. ill give other examples when explaining fungibility next
LN is fungible? again, you must be joking,
1. when creating a route some route decide rules, such as not wanting to connect to nodes of certain value, meaning some funds are treated differently and not accepted
2. its like saying 'i only wanna channel with you if you hold a $50 bank note. sorry if you only have a $10 bank note, goodbye
3. then its like 'ok you got a $50 bank note, but if your not willing to swap it in daily amounts of $1 then i got no use for you'
LN is not as connect to anyone anywhere for any amount.
please i really do think you should do some research. i mean this sincerely. really look beyond the glossy promo material and actually research beyond their buzzwords.
and if you still think that LN is better than the fiat system research what CLTV and CSV actually enable as features from the prospective of users.
here is a hint.
CLTV=3-5 business day funds locked on wire transfers(closing channels)
CSV revoke= chargebacks
sound familiar to the fiat system
good luck in your research, have a nice day
