what he says is correct..
visa's "authorization network" (the one that doesnt settle transactions but just says ok or not before the funds actually move) can handle a CAPACITY of 42,000 authorizations not settlements.
and blockstream who have consultants as part of PwC who are IBM.. yes the same company who help out VISA and the same company who were writing in the article..
so yes blockstream want bitcoin to turn into a more centralized system like visa's where it has a authorization network(handles tx's in seconds) and days later settles the accounts.
but they fail to debunk one big thing.. bitcoin does not have 900million users. and so any doomsday story that bitcoin cannot scale to visa ONCHAIN is a flawed argument. with the only intention to move the smaller population away from bitcoin and onto less secure, less distributed networks or centralized hubs.
which ultimately will dilute the pool of full nodes if people are playing with sidechains because they realise they dont touch bitcoin onchain and so ignorantly become central hubs/sidechain nodes. which along with pruned mode, no witness mode and everything else also reduces the distribution of real full bitcoin nodes.
so the slow growth ONCHAIN over many years will not disrupt bitcoins security/distribution of nodes as much as diverting people away from bitcoin will.
so yes the debate is not about classic vs core...
its about code simple change or major change.
its about security, everyone concentrating on using the same fundamental protocol rules and same network/same ledger. or different networks different rules, different ledgers.
the last part of blockstreams plan is to make bitcoin not even a ledger(record of account) by bloating each transaction by 250bytes to hide the values of spending(confidential transactions). making it harder for the network to trust that a bug hasnt suddenly created billions of bitcoins. or that a double spend has or hasnt happened. again risking the fundamentals of bitcoin.
all because blockstream has ties to VISA and multiple banks, all via the go-between PwC
"Blockstream wants to centralize Bitcoin" FUD has been proven wrong a million times.
It has also been proven with data that increasing the blocksize too soon will centralize nodes. Running a node is a pain in the ass now, imagine if you make the blockchain grow twise as fast.
You are just playing the stupid conspiracy theory. "all because blockstream has ties to VISA and multiple banks, all via the go-between PwC"
Oh so guess who has ties to CIA, Gavin, guess who has ties to Google and directly works for banks, Mike Hearn... see, we all can play that game.
At the end of the day, the best devs are the Core devs, and the only devs that came up with a solution for the problem (Lightning Network) without centralizing the core of Bitcoin (the only thing that makes Bitcoin valuable is that its decentralized, if you lose this then it's worthless).
Bitcoin will never scale to global levels all on-chain without massive centralization, so LN is the best solution.
