Staking-as-a-service (SAAS)
There are expert third parties with data center infrastructures that offer staking-as-a-service (SAAS). Users with enough capital to stake the entire node can run validation through third parties in exchange for operational fees.
Staking services give users more flexibility to run different validation nodes and easily change blockchains and providers without expert knowledge of the protocols. The third-party infrastructure is also less likely to suffer downtimes or security issues that could lead to slashing of base capital (see Risks).
This model offers near-direct access to rewards. However, it requires large staking capital and trusted third-party providers.
