Storage network
What it is
A network that turns file storage into an open market: clients pay providers to hold data, and providers must keep proving to the chain that the data is still there.
Why this risk level
- A storage deal is enforced by two cryptographic proofs — one that the provider encoded the client's specific data, and one submitted repeatedly over time that they still hold it — with staked collateral slashed for failing them
- The chain stores the deals and the proofs, not the files, so retrieval speed and availability depend on the provider you contracted with rather than on the protocol
- FIL pays for deals and gas and is the collateral providers must lock to take on storage; the price of a deal is negotiated in the market rather than set by the protocol

Aave
DeFi governance token
A decentralised lending protocol where deposits sit in shared pools and borrowers take overcollateralised loans against assets they lock, with interest rates set by how much of a pool is in use.
Why this risk level
- Loans are overcollateralised and enforced by contract: if the value of your collateral falls far enough relative to what you borrowed, anyone may liquidate part of the position and take a bonus for doing it
- Deposits are not insured — the risks are smart-contract failure, an oracle reporting a wrong price, and market moves too fast for liquidators to clear bad debt
- AAVE is a governance token used to vote on protocol parameters and to backstop the system under its safety module; it is not a deposit account and not a claim on the pools
Algorand
Smart-contract platform
A smart-contract network whose consensus draws a fresh random committee for every block and finalises it on the spot, so the chain never reorganises and confirmations are not a waiting game.
Why this risk level
- Block producers and voters are selected by a cryptographic lottery weighted by stake, and the selection is verifiable after the fact but not predictable in advance, which is what makes targeting a specific proposer difficult
- Finality is immediate rather than probabilistic: once a block is agreed it is not revisited, so applications do not need a confirmation count before treating a payment as settled
- ALGO pays transaction fees and is the stake that weights the lottery; participation does not require locking coins away from the account that holds them
Aptos
Smart-contract platform
A proof-of-stake layer-1 launched in October 2022 by engineers from Meta's abandoned Diem project, built around the Move programming language and an execution engine that processes independent transactions in parallel rather than one after another.
Why this risk level
- Move is the distinguishing feature rather than the marketing: assets are represented as typed resources that the language itself forbids from being copied or silently discarded, which removes at the language level a category of bug that Solidity contracts have to be audited for
- The pitch is parallel execution — transactions that do not touch the same state are processed simultaneously — so throughput claims should be read as a ceiling under favourable conditions rather than a rate you will observe on a busy day
- The chain launched with a large share of the supply allocated to the core team, early investors and the foundation, released on a multi-year unlock schedule, so circulating supply has risen on a published timetable independently of demand
- It competes directly with several other well-funded Move and parallel-execution chains for the same developers, and an ecosystem's depth — not its benchmark numbers — is what determines whether a chain retains them
Arbitrum
Scaling network
An optimistic rollup that executes transactions off the Ethereum main chain and posts the results back to it, so users pay Ethereum-level security costs only once per batch.
Why this risk level
- Transactions are ordered by a sequencer and settled on Ethereum, so fees are far lower than transacting on Ethereum directly while the final record still lives there
- Withdrawals back to Ethereum pass through a challenge window measured in days, during which a fraud proof can dispute the posted result — bridges that offer instant exits are third parties taking that risk for a fee
- ARB is a governance token for the protocol's DAO; it is not the network's gas token and does not confer a share of sequencer revenue
Avalanche
Smart-contract platform
A proof-of-stake smart-contract platform designed around fast transaction finality and the ability for projects to run their own separate, application-specific chains.
Why this risk level
- Transactions reach final settlement in seconds rather than minutes
- Projects can launch their own chains with custom rules instead of sharing one congested network
- The developer and application ecosystem is meaningfully smaller than Ethereum's, which affects both available liquidity and the maturity of the tooling
Bitcoin
Store of value
The original cryptocurrency and still the largest by market value, with over fifteen years of continuous operation and no successful attack on its core network.
Why this risk level
- Longest track record of any crypto asset by a wide margin
- Most decentralized and battle-tested validator (miner) set
- Still far more volatile than traditional stores of value like gold or bonds
- Supply is capped at 21 million coins — the scarcity argument rests on that cap, not on any yield the asset pays
