BREAKING: Ted Cruze says, “I have a weekly buy order in for #Bitcoin… I am a big fan of DCA… when it dropped I bought $25k in #Bitcoin… I am bullish on Bitcoin so I’m proud to say I have skin in the game.”

4000 hashes per second would generate an additional 160 kilobytes of data, and would require access to a GPU with 4000 cores and roughly 0.25-0.75 milliseconds of time to verify.

@jimmysong Currently 9 for BTC but 35 for #Litecoin play with pocket change before moving to the big money.

People feel much more comfortable buying some #LTC to dip into the space than #BTC at this time.

Also mistakes are not as costly when learning.

Now this is some proper POW = Proof Of Wall.

@saylor @adam3us Saylor you must see that there is room for more than one use for blockchain other than just money right?

[On-Chain Mike @OnChainMike]

@Mandrik @crayonsmell Ohhhh that is nice!

[Mandrik @Mandrik]

Looks even better in person. Amazing work, @crayonsmell!

A naive implementation of the state as a 50% full hashtable with 32 byte entries for each account, would theoretically fit 10 billion accounts into 640GB.

Steady state random access to this table is measured at 1.1 ∗ 107 writes or reads per second.

A single proof that samples 1 byte out of every
megabyte would have a likelihood of collision with any erased byte 1 − (1 −1/1, 000, 0000)1,000,000 = 0.63. After 5 proofs the likelihood is 0.99.

Total time to verify proofs is expected to be equal to the time it takes to encrypt. The proofs themselves consume few random bytes from the block,

[On-Chain Mike @OnChainMike]

With N cores, each core can stream encryption for each identity. Total space needed is 2blocks ∗ Ncores, since the previous encrypted block is necessary to generate the next one. Each core can then be used to generate all the proofs that derived from the current encrypted block.
