# Avalanche replication
|
|
|
|
The [Avalance explainer video](https://www.youtube.com/watch?v=qt_gDRXHrHQ) is
|
|
a conceptual overview of how a Solana leader can continuously process a gigabit
|
|
of transaction data per second and then get that same data, after being
|
|
recorded on the ledger, out to multiple validators on a single gigabit
|
|
backplane.
|
|
|
|
In practice, we found that just one level of the Avalanche validator tree is
|
|
sufficient for at least 150 validators. We anticipate adding the second level
|
|
to solve one of two problems:
|
|
|
|
1. To transmit ledger segments to slower "replicator" nodes.
|
|
2. To scale up the number of validators nodes.
|
|
|
|
Both problems justify the additional level, but you won't find it implemented
|
|
in the reference design just yet, because Solana's gossip implementation is
|
|
currently the bottleneck on the number of nodes per Solana cluster. That work
|
|
is being actively developed here:
