In the whitepaper it's written The edge set of the tangle is obtained in the following way: when a new transaction arrives, it must approve two (1) previous transactions. 1: This ...

In IOTA, every new (unconfirmed) transaction is known as a tip. These tips should each reference two previous transactions. Choosing which tips to extend is decided by a Random Walk Monte Carlo ...

The 2 parents of a transactions are called trunk transaction and branch transaction. You get them like this: (It's python but the names and arguments in other libraries are very similar) getTips ...

First of all, the property of a transaction being a tip is volatile and can change before the walk even finishes. So even if the function was guaranteed to find a tip, by the time it returned it could ...

The tip count is the number of tips currently "in memory" (i.e not in permanent storage/database). Therefore it's 0 when IRI restart. A new entry is added to the set of tips "in memory" when a new ...

A transaction is confirmed once it is transitively approved from a milestone transaction. (At the moment, milestone transactions are chosen by the coordinator, but in the future the MCMC algorithm ...

Tips in the context of iota (if they are not meaning small payments, as in tipbot) refer to transactions that have not been confirmed by other transactions. When you make a new transaction, you (or ...

Yes, you can manually specify the parent messages to which your new message refers. This is done by providing the parents field when creating the message. However, you should be cautious when doing ...

The tips/parents are randomly chosen and I quote: A node should keep a set of non-lazy tips (score 2). Every time a node is asked to select tips to be approved, it will pick randomly from the set. A ...
