Question Data availability in the vProgs design
In many rollups mechanisms there's a need to save the pre-image of the most recent state commitment in order to continue operating. This means that once the rollup validators lose the state the rollup can't operate anymore. This data availability problem has implications on atomic composability, s...

Answer A: How many Transactions per Block?
The theoretical maximum is 856. You can find here a more detailed answer. It's hard to answer what's the average, because it depends on a time frame, but you can follow real usage in kas.fyi.

Comment Post #42 No - blue blocks get both fees and subsidy (what you call "reward"). When I say "block reward" I usually include the transaction fees in it.

Answer A: What is Kaspa max tps?
Although @tty's answer is technically correct, it represents a peak TPS due to fluctuations in the block rate, which doesn't represent Kaspa's throughput over time. I think a more interesting metric is the average TPS, which can be calculated as `BPS MAXTRANSACTIONSPERBLOCK` (where `BPS` denotes "Bl...

Answer A: Fees and VSPC(Virtual Selected Parent Chain)
No, in Kaspa each blue block receives a reward. The main reason is that rewarding only chain blocks (VSPC blocks) creates incentives for selfish mining. But there are other (milder) advantages to being a chain block: 1. In GHOSTDAG ordering, it precedes any block in the same mergeset - therefo...

Comment Post #38 This post violates the guidelines for two clear reasons: 1. Language – Both the question and the answer are written in Russian. Since the site requires all content to be in English, this prevents most of the community from being able to read, answer, or moderate effectively. 2. Exchange Recomme...

Answer A: Is there a CLI tool to send RPC commands?
Yes, `rusty-kaspa` comes with the tool `kaspa-cli` that supports sending RPC command. For example, to send the RPC command `get-block-dag-info` you'll need to do the following: ``` git clone https://github.com/kaspanet/rusty-kaspa.git cd rusty-kaspa git checkout stable cargo run --release -...

Answer A: What's the difference between transaction payload and OP_RETURN data?
In Bitcoin, OPRETURN is essentially a hack for publishing data on-chain without bloating the UTXO set: `OPRETURN` is a Bitcoin opcode that makes the script fail instantly. Therefore, an output with scriptPubKey of `OPRETURN ` is provably unspendable and therefore Bitcoin Core v0.9 introduced a pol...

Answer A: Do red blocks get block reward?
Yes — red blocks themselves don’t receive rewards, but there’s an important subtlety. If rewards were simply destroyed whenever a red block appeared, the issuance rate of new KAS would fall behind schedule. To avoid that, the protocol almost always reallocates the reward to the “merging block” — t...

Question Do red blocks get block reward?
GHOSTDAG partitions the blockDAG into blue blocks and red blocks. In the final ordering, blue blocks take precedence, while red blocks are placed after them (unless the DAG’s topology forces otherwise). My question is: does Kaspa penalize red blocks by excluding them from block rewards?

Answer A: Does Kaspa support atomic swaps?
Yes. Any cryptocurrency that supports HTLC can support atomic swaps, and since Kaspa-script is very similar to Bitcoin-script, the implementation would be practically the same.
