Agreement can then take one or two voting rounds.
Removing those votes will also make some Solana activity charts fall. Transaction totals that include validator votes will shrink even if users make just as many payments and trades. The Foundation has told data providers to adjust their comparisons.
Services that build transaction histories also need to keep competing candidate blocks separate until the network selects one. Mixing their contents could produce an incorrect record.
Applications that simply send transactions and read account balances require no migration, according to the Foundation’s guide.
The speed figure remains a target derived from simulations, rather than a…
