The first split was between a moving balance and a vote
Lido began on Ethereum in December 2020 as a pooled route into Beacon Chain validation. A depositor received stETH instead of operating a 32 ETH validator. stETH represented a share of pooled ether and changed balance as oracle reports brought rewards, penalties and fees into the accounting.
wstETH later packaged that same economics for systems that cannot handle rebases. Its wallet amount stays still while each unit converts into more or less stETH. It is a wrapper, not a second validator balance or a second claim on the pool.
LDO sits outside both receipt forms. One billion LDO was minted at DAO launch and the current explorer state still reports that total. Voting uses committed LDO, but the verified MiniMe token remains controlled by an Aragon TokenManager with permissioned mint and issue functions. One billion describes launch and current supply, not an immutable cap. LDO neither enters the ETH withdrawal queue nor accrues validator rewards merely because the protocol earns them.
