### What is the Actual IOTA Algorithm for Tip Selection?

The IOTA Whitepaper dances around suggestions as to how a tip selection algorithm should be constructed. We need checkpoints for security to ensure that λ > μ (Arrival rate of honest nodes) > ...

### Iota White paper section 4.4. Random walkers

My question is regarding section 4.1 of Iota white paper. I really don't understand how particles or random walkers will be actually placed by the nodes in the tangle. What they state is : "The node ...

### Theoretical delay before first approval

I'm reading the white-paper about the tangle. In pages 8 to 10, the author is calculating the average time for first approval of a tip on a stationary tangle. The first result is that under low load: ...

### IOTA Whitepaper: What is z in Section 4.1?

Everything in the equation is defined except z. Is it supposed to be another parameter that is chosen like alpha? I want to actually use some reasonable sample variables and test this.

### IOTA Whitepaper: What is δ?

In Section 3.1 of the IOTA Whitepaper it refers to small delta (δ) but does not actually define what it does. Can you help define δ and explain what the equation is trying to tell me?

### Iota Whitepaper: What is “k” in Section 3?

The IOTA Whitepaper in Section 3 does not seem to define k. Is k the number of verifications required by a transaction as noted earlier in the Whitepaper or something else? If it's the former I do not ...

### “The Tangle” white paper: How the probability of double-spending event end with this approximation (t_0 μ)/w_1?

If the attacker managed to obtain a nonce that gives the double‐ spending transaction a weight of at least 3n0 during the time interval of length t0, then the attack succeeds. The probability of this ...

### What is a conflicting transaction?

The term is used many times on the whitepaper but I can't find a definition. What would be examples of a conflicting transaction? Extract form Whitepaper: The main idea of the tangle is the ...

### What is the purpose of numWalks API parameter?

The IOTA whitepaper describes the tip selection algorithm in the Section 4.1. The idea there is to select N starting points in the tangle randomly (subject to some conditions) and then to do a random ...

### IOTA Whitepaper Math Section 4.1: Am I calculating this right?

I'm trying to craft an example going through the math equation in Section 4.1 . I'm trying to show my work. Can you tell me if I've got it right and if not, help correct me? Hx – Cumulative weight ...

### IOTA Whitepaper: What is n in Section 4?

I am trying to wrap my head around n in Section 4 of the IOTA Whitepaper. I get that W is weight, but n does not seem to be defined. Can anyone please help me understand it?

### How to compute the % of network computing power the attacker hold?

It is known generally that Tangle is susceptible to 34% attack(of total computing power) that gives a 100% successful attack. The example given on page 19 of white paper says that an upper limit to ...

### how to relate computing power of attacker to transaction rate of attacker?

Assume that the merchant accepts the legitimate transaction when its cumulative weight becomes at least w_0, which happens t_0 time units after the original legitimate transaction. let μ stand for the ...
