what types of apps that dont have to keep events/block/txn history?
reverse gas model…. but also…. reverse history model.
Ethereum…. transaction history built in.
ICP…… ICP history not built in….. you must explicitly implement history, unlike traditional blockchains that do history by default.
Here are solid categories where you can usually skip history completely and keep things simple + cheap on cycles:
-
Pure computation / stateless endpoints
- Math solvers, unit converters, random number generators, basic simulations
- Lightweight oracles that do HTTPS outcalls and return fresh results
- One-off calculations or inference calls
-
Real-time / ephemeral apps
- Live chat signaling or WebRTC coordinators (messages not stored on-chain)
- Temporary multiplayer game matchmaking or session lobbies
- Anonymous polls/votes where only the final aggregate count matters
- Quick matchmaking or pairing tools that reset after use
-
Static or mostly-read content hosting
- Decentralized websites / frontends served directly from the canister
- NFT metadata endpoints (if ownership history lives elsewhere)
- Docs, wikis, knowledge bases, or rarely-updated static content
-
Proxy / router / gateway canisters
- Load balancers, API gateways, or call routers to other canisters
- Rate-limiting or access-control layers that don’t need audit trails
-
Simple configuration / control-plane services
- Feature flags, allow/deny lists, parameter stores
- Admin-updated settings that users just query (current state only)
-
Fire-and-forget actions
- Form submissions that trigger external HTTPS calls (send email, post to API, etc.)
- One-shot notifications or triggers with no need to remember they happened
-
Dev/testing tools
-
Playground canisters, mock services, temporary sandboxes
TLDR: bAsIcAlLy LiKe AwS LAMBDA type -ish.
