i feel that this is just trying to make LN seem like it was always part of bitcoin. even though the concept is actually
part of blockstreams 'liquid' concept 2013+.
EG multisig was not part of bitcoin in 2009-2011
EG CLTV /CSV was not part of bitcoin in 2009-2011
No this is not about the Lightning Network, but the concept of offchain transactions. Blockstream did not say anything about the concept back in those days. Was Blockstream already alive during that time?
It was Satoshi who said it and clearly expressed that the blockchain can become a "settlement layer".
"Only the final outcome gets recorded by the network". Said Satoshi.
but lets be devils advocate
the 2009-2011 nlocktime would be used by people (real world analogy) in a poker game, players writing their own cheques to 'the house' dated 10 days in the future,
(the house does not counter sign nor has a joint bank account with the poker player)
while the poker game is in play, the house never hands th cheques to the bank to clear/settle.
then if the player needed to buy more poker chips. the player would write out a new cheque dated in 9 days. and the old cheque gets destroyed as its now useless. because the house would obviously prefer to cash a cheque that is dated sooner and for a larger amount
there was no revocation keys. no house having a joint bank account with the poker player to hand funds back inhouse
it would be just a one way payment system.. like a bartab..
satoshi envisioned a small private bartab concept for a small group of people that knew each other.. not a full pupulation co-signing offchain bank branch concept
in no way was it mentioning a single offchain NETWORK for everyone to use because bitcoins blockchain is limited and not able to scale. it was a concept of small parties (friends/family in a room) signing away from the payment system so they can (play poker for instance) without waiting for confirmed funds to get their poker chips
so trying to say satoshi/hearne invented LN or said LN is the acceptable/endorsed as a sole solution is really trying too hard to hide that LN is actually a 2013+ concept by blockstream(liquid)
LN is by magnitudes meandered away from private small group concept
LN is by magnitudes meandered away from the whole purpose of blockchain peer community validation
LN is by magnitudes over promoting but under delivering promises of limitless trustless fast payments.
i have used offline signing concepts and even multisigs between me and family/friends/business partners. i have seen the flaws and limitations
i have run scenarios about the funding of multisigs and replenishing funds and how often it would be required to do so.
i have run scenarios about how centralised the offchain network would need to become to be reliable and well funded and not an obstacle to average joe.
so far all LN devs have done is ensure node A connects to node B to connect to node C to ensure payment gets from a-c.
they have not yet done the long term multiple spending scenarios to see A raids B's holdings when routing a-c and/or B closes the route causing issues between a-c.
EG to use LN you need to have a certain amount just to be an acceptable channel partner, cover punishments and other fee's and then reserve part of that for use of routing. and splitting those funds over a couple 'accounts' just to be a reliable route.
meaning forget a third world user having just $2 and having all the utopian promises so he can buy 20 loaves of bread for the next month+ without hassle.
the devs have not seen that LN is not a scaling solution for everyone. because there are limitations. they have over promised, over promoted and under delivered.
and so there is a requirement to expand the blockchain scaling. NOT stiffling onchain scaling to force people into using limited use LN because of fee wars caused by stiffling onchain scaling.
But Satoshi did say that offchain transactions is one of the ways to help scale the network, did he not?
I am not talking entirely about the implementation of the Lightning Network, but the concept behind offchain transactions.
Some Exchanges such as Cryptopia & Trade Satoshi can do Offchain Scaling with Any amount & any crypto on their site
Right Now.An Exchange Offchain Transactions are not limited and are not time locked for extended times.
Basically an Exchange can provide everything LN promised
(but has yet to fulfill) without the dangers or limitations of LN.
Since an exchange is only transferring the actual virtual coins and not creating a separate payment
(Bank Notes Style) System ,
the exchanges are not going to be required to get a banking license like an LN Hub will be required too.
Exchange can also process these offchain transactions at a much cheaper fee structure than LN Hubs.
Comparisons
Exchanges Offchain Transactions Verses LN Offchain Transactions
No Amount Limit verses Amount Limits
No Time Locking verses Time Locking
Easy to use, send to user name verses Extremely Complicated
Lower Fee Structure verses Higher Fee Structure
(due to needing multiple hubs to complete channels)Centralized to that exchange verses Centralized to the # of hubs needed to complete the channel
Received Onchain Payment Faster verses Slower receipt of Onchain Payments due to waiting for the time locks to expire
Better Support Structure verses No Real Support Structure
For people wanting fast affordable offchain transactions,
Exchanges outperform LN Hubs.
