@kristovatlas @slushcz I can offer a solution to this problem if you can find me :-)

@Aquentson Capital costs are known; as for HODLing, some miners have stated it. If you want cryptographic proof of HODL, we don’t have that.

Miners secure network via Proof of Work, but also have a huge stake (capital investment & coins held) in Bitcoin’s success.

@_marty_jones @Ethan_Heilman @el33th4xor Hubs would likely have unused keys available - they’d need them to establish new outgoing channels.

“With a timestamping proof format, we can service all global timestamping needs with only 1 txn per block.” - @RCasatta

@Ethan_Heilman @el33th4xor If everything is working as intended, would be better to target privkeys not being used in a channel.

“2% of daily bitcoin transactions are currently using OP_RETURN; likely half are for timestamping purposes.” - @RCasatta

@el33th4xor I suspect that large LN hubs will be natural targets for both hacking (for hot wallets) and DoS (for ransom?)

“Everyone should use BIP69, canonical ordering of inputs and outputs.” - @tdryja H/T @kristovatlas! github.com/bitcoin/bips/b…

@el33th4xor I don’t think it can be predicted with confidence; won’t know until it’s built. But if any nodes get too big, just DoS them!

Payment channels must be watched by a full node, but this can be outsourced to 3rd parties securely & privately. - @tdryja

“Decoupling dependencies like consensus, DB, networking, w/separate interfaces can make it easier for devs to use Bitcoin.” - @eric_lombrozo

@drwasho There are different approaches to increase privacy; CoinJoin / ZK Proofs / CTs increase blockchain data but MW / LN decrease it.

“With Sinking Signatures, can reduce 500,000 blockchain to 300 blocks, 1MB of headers, verifiable in 20s.” - Andrew Poelstra

“MimbleWimble blockchain verification just requires block headers + current UTXO set + range proofs for each output.” - Andrew Poelstra

via Twitter Web Client

MimbleWimble, like Bitcoin, was invented by an anonymous author using pseudonym “Tom Elvis Jedusor” (Lord Voldemort) download.wpsoftware.net/bitcoin/wizard…

via Twitter Web Client

MimbleWimble is a blockchain design that’s massively prunable - it offers improved scalability & privacy at cost of removing script support.

“TumbleBit uses RSA blinding to create unlinkable HLTCs, thus the hub can’t track payments between users.” - @Ethan_Heilman

via Twitter Web Client in reply to lopp

TumbleBit can operate as a unidirectional payment hub, offering increased privacy & scalability over standard BTC tumblers. - @Ethan_Heilman

via Twitter Web Client

CoinJoin’s anonymity set: the people w/whose coins you’re joining.
CoinSwap’s: everyone using it on the network @ that time.

via Twitter Web Client

Lightning Network and MimbleWimble appear to be most promising tech that can increase both fungibility & scalability. H/T @TheBlueMatt

via Twitter Web Client

“Increasing fungibility is generally achieved by reducing information leakage, which may mean reducing use of blockchain space.” - @adam3us

via Twitter Web Client

“Some Bitcoin services use taint analysis to shut down accounts; their users have less fungibility than Paypal users.” - @adam3us

via Twitter Web Client

To be clear, this isn’t a vulnerability - it could be useful to enable secure message passing on Lightning Network. twitter.com/lopp/status/78…
