1  Bitcoin / Development & Technical Discussion / Re: Block reward <1 btc re-orgs vector viable? Eg Binance on: May 16, 2019, 09:30:54 PM
Sorry. I suck in math. How large is that?
Three years ago it was 2.8MB.

But what is the "optimal block size"? That's the mystery that all cryptocurrency developers wants to know.
I'll try to uncover this mystery for you and the rest of cryptocurrency developers. The optimal block size is ~25% of the average residential line throughput divided in 10 minute chunks.

I don't see another way out of this situation.

Node reward are countless hours of effort otherwise lost/stolen through currency debasement.

For a person who claims to be "smart", you don't sound as smart at all. You only repeat the big blocker propaganda without truly knowing the finer points of how Bitcoin works.
You waste the time arguing with a troll instead of ignoring him.

Feel free to create more block space, it isn't that hard. As a side effect this will end Veriblock's raison d'Ítre.
6  Bitcoin / Development & Technical Discussion / Re: 1000x throughput on transaction batching + privacy boost using Script Bitfields. on: April 02, 2019, 12:23:44 AM
We store it in a bitfield. 1024 Bits is 128Bytes.
This bitfield goes into every transaction 1024 times. Adding to this Merkle path and comparing to 250 bytes of an average transaction I would doubt even 1x throughput.

The original transaction ( the one where the 'transaction batching' is going on ).. is still 1000x times smaller.. with a fee which is 1000x smaller. And you'll still have paid out to 1024 users.

Merkle trees are useful when plain cryptography is not enough, like in inter-chain communication. In this proposal you are attempting an uneasy task to compress thirty-something bytes per output even more.

An interesting idea but you will need another 1024 transactions to spend from the batch. Therefore throughput becomes 2x, even less taking into account all overhead.
9  Bitcoin / Development & Technical Discussion / Re: Proposal Ethereum as the layer 2 to Bitcoin on: March 21, 2019, 01:44:55 PM
Your proposal assumes that scaling of Ethereum is a done deal. However Buterin's declaration about 100000 transactions per second is not quite enough, proofs are needed as well.
10  Bitcoin / Bitcoin Discussion / Re: Should bitcoin be limited to 21 million? on: March 21, 2019, 02:14:38 AM
I see this question more as political than technological one. There are powerful groups interested in preserving their money emission monopoly. By removing the cap you are offering them ammunition that will be used against yourself.
11  Bitcoin / Bitcoin Discussion / Re: Should bitcoin be limited to 21 million? on: March 19, 2019, 05:07:11 PM
I would say keep it at 21 millions for the sake of experimentation. Never before has existed anything like this, even gold suffers from small yearly inflation.
12  Bitcoin / Development & Technical Discussion / Re: Modular Scaling on: March 17, 2019, 11:35:59 AM
Blockchain data has a high degree of randomness. Therefore any kind of compression, yours included, will yield an insignificant improvement.

ATM operators should have waited until replace-by-fee transaction got included in block. Instead they disbursed cash as soon as zero confirmation transaction had been broadcast.
14  Bitcoin / Development & Technical Discussion / Re: What is sharding, and will sharding scale Bitcoin? on: February 28, 2019, 09:39:50 PM
I don't see the point of this complexity. Why not just squeeze these two leaves in the same block. User downloads and verifies his leaf up to Merkle root because in Merkle tree transactions are arranged by shard. There is some overhead because Merkle paths are required to verify atomic swaps between shards but this can be reduced by grouping atomic swap transactions by shard as well. This overhead is actually the only restraint otherwise the scaling would be limitless.

Edit:
There is an additional small problem to consider. When we split a shard in two by transaction id to scale further, amounts of coins in two children will be different. Atomic swap rate between them will be nowhere near 1:1 leading to rampant speculation. Therefore users will have to anticipate these splits and divide their coins in advance to hedge value.
15  Bitcoin / Development & Technical Discussion / Re: What is sharding, and will sharding scale Bitcoin? on: February 27, 2019, 01:58:02 PM
Miners don't need to mine different shards, they can form pools that have enough resources to mine a big block. But users download and verify only their own shard, this is the whole point of sharding.
16  Bitcoin / Development & Technical Discussion / Re: Sharding strategy held together by atomic swaps on: February 15, 2019, 05:05:42 PM
So miners get their fees with n shard transactions and block reward goes to a shard of their choosing (the most valuable one). All inter-shard transfers are done with atomic swaps. This way gigabyte blocks are no longer a problem.
17  Bitcoin / Development & Technical Discussion / Add reference transaction hash to Merkle tree for atomic swaps on: January 27, 2019, 12:08:41 AM
Now every transaction is represented by one hash in Merkle tree. Also current atomic swap implementation is bulky and slow.

With two hashes for transactions involved in atomic swaps the first hash is the usual bitcoin transaction hash and the second one is the hash of the correspondent transaction on an altcoin. In order to spend from this kind of transactions the altcoin transaction has to be already included in its blockchain with n confirmations. So this means that bitcoin miners will monitor the altcoin Merkle tree as well.

There are people that like easy money to an extreme degree. They attack once, then after a while rinse and repeat.

The real problem of bitcoin, however, isn't in this.  The real problem of bitcoin is its huge waste of economic value.  One tends to think that bitcoin is a zero-sum game, but it isn't: it is very very lossy.  The value economically wasted by PoW is extracted from the system to go nowhere.  In the long run, that's not sustainable.
This is from the book of the Bank for International Settlements and Co. Actually bitcoin is a perfect wealth creation machine (and not only for miners but for the whole society) that doesn't waste a single Wh.
