21) There were some other ideas whose details I've forgotten -- "big blocks/small blocks", "some small validator that has some power"--

@VitalikButerin

do you remember those? -- The other set of ideas were about storing state securely and efficiently.

22) The goal here would be two-fold: make sure history can't be rewritten; and that it's easy for a low-powered validator to find out the state of the blockchain. One idea here is just writing the state to the ETH blockchain periodically. Then any ETH node could verify Solana.

23) Another idea was to write ZK-proofs of a Merkle tree of the blockchain, or something like that. A third thing that Vitalik brought up: it would be great if each block header contained the full state of the blockchain, so at least verifying that was easy for a laptop.

24) I'm probably missing a lot of his thoughts here, and probably misrepresented some too--sorry! But I found the conversation super interesting. There are sometimes tradeoffs between security and speed, but at least we can try to find a pareto maxima.

25)

-- how did I do summarizing this? What are your thoughts, in your words?

@aeyakovenko

-- thoughts on the above?

Interesting thoughts even if

@solana

is promising it suffer imo of two main issues (to solve ) : 1. A leader validator can stuck the BC 2. Seems you can create a solana token program(like smart contract on ETH) but cannot read the contract on solana bc like you can read on ETH ?

(1) isn't true (2) isn't blockchain-level, it's app level. Etherscan built out a neat tool to do this; someone could do it for Solana too (and hopefully will!)

Replying to

(1) medium.com/solana-labs/ma (2) agree (3) solana still a promising tech fast and cheap, some tools(like explorer) has to be improve/develop

1 isn't a design flaw, just a known issue/bug that is getting rolled out in the next release cycle. Beta has performed incredibly well since launch, 7b txs between stalls is a Mean Load Between Failures that is larger than anything else out there.
