contracts: Remove state rent #9669

athei · 2021-09-01T10:04:21Z

This PR removes state rent (data, code) from the pallet_contracts code base. It greatly reduces complexity and allows coming changes to be much simpler to implement. It includes a storage migration and is backwards compatible for existing contracts (for the ones not using the unstable-interface feature). Tombstones are no longer a thing and existing ones are removed by the migration.

Motivation

The pallet_contracts was designed from the beginning to combat unbounded state growth by using state rent (charging contracts for the state they consume). The main reason for the introduction appears to be that this is what Ethereum was exploring at the time. The idea is elegant because it pushes the policy decisions around contract financing to the contract authors and allows them to experiment with different ideas rather than enforcing one at the runtime level.

In practice however, it turns out that state rent is really difficult to deal with and the smart contract audience is not equipped to deal with this issue and simply uses any other solution where this is not a thing. Please keep in mind that in contrast to runtime development where flexibility is key we are going for a crowd where ease of use is paramount. Additionally, Ethereum itself abandoned the idea and is on track on using what they call state expiry. Something that could be added to substrate later as a runtime opt-in for smart contract hosting chains.

The conclusion is that rolling out state rent will put us as a severe disadvantage with regard to adoption when compared to other smart contract technologies with regard to adaption without any short to medium time gain. Even on Ethereum with years of heavy usage on its back running a mining node is still something totally feasible. With the luxury of runtime upgrades and storage migrations we should solve the problem in a less intrusive way later.

Implementation

The PR mainly deletes code and adjusts tests/benchmarks. The biggest change is that the concept of a tombstone is gone. The TombstoneDeposit is renamed to ContractDeposit and is a deposit a deployer needs to deposit into the new contract on top of the ExistentialDeposit (no change to the previous behavior). Please note that seal_terminate can still be used to remove a contract and is the only way to remove a contract and regain the deposit.

One side effect of this change is that the ContractInfo data structure no longer contains any mutable data. Meaning that all the data there is fixed at the point of contract instantiation. This makes the ContractInfo caching we do obsolete. Instead of deleting the code I hid it behind the CONTRACT_INFO_CAN_CHANGE constant which can be switched to true once we change the structure to contain mutable data again.

Security Discussion

With the removal of state rent we open the door for attackers that try to DoS the chain by creating as much storage as possible. This is because you pay once (in weight) to create the storage but it needs to be kept around forever by collators (in absence of a future solution like state expiry). The means of making this attack economically infeasible is to adjust the Limits::payload_len field which determines the maximum amount of storage per key. Lower sizes make creating storage more expensive because creating or updating storage items is expensive in weight. However, for maximum flexibility and efficiency we want to set the value as high as possible.

Please keep in mind that this attack would not affect the relay chain because validators do not need to keep the state of a potentially smart contract hosting parachain.

I propose setting the maximum value size per key to 512 bytes as an initial value (ethereum uses 32 bytes for various reasons). We can always increase the value but lowering it would be a breaking change. This would put the price of 1 GB of storage on Kusama to 271 KSM. Calculation here. Try to play around with different values. These are the weights obtained through benchmarking I used for the calculation (1ps = 1 weight = 1 unit of balance):

set_storage: "129.1 µs",
set_storage_per_byte: "851 ps"

Those values seem rather low but note that:

It gets more expensive when the chain is used more (price of the balance unit and balance price of weight)
- The 1 weight = 1 balance unit is the worst case (cheapest case)
This is still above what 1GB would have costed on ethereum in 2017

Please keep in mind that we are not trying to find a long term solution due to these calculation but merely try to avoid a DoS attack.

Porting Guide

Smart Contract Languages

All existing stable functions are retained and are replaced by doing nothing or returning sane default values. The unstable seal_rent_params and seal_rent_status are removed.

Nodes

All rent related configuration options are removed from the Config trait. Remove them without replacement as your compiler requests. The public rent_projection function is removed and rent_projection field is removed from the return types of bare_instantiate and bare_call.

Offchain Tools

@jacogr

polkadot-js/api#3925

The rent_projection RPC is removed and the rent_projection field is removed from the instantiate RPC result type. The in-storage ContractInfo type changed and need to be synced with typescript.

Why not just charge a fixed deposit per stored byte? Charge storage by gas makes no sense nor does weights.

If you guys decide to remove rent, I advise to recover put_code

Why not just charge a fixed deposit per stored byte?

The "just" is doing a lot of heavy lifting here, though. Making the caller pay a deposit is the obvious solution but it has some open questions associated with it. It is certainly something that we consider and it might be implemented. However, the code that is removed here can't be reused for that because it is all about the contract being responsible for paying the rent/deposit which is fundamentally different.

Why this solution wasn't explored before was the stance that we want to give smart contract authors maximum flexibility with their financing model. However, It turned out that the current approach provides that but didn't pass the reality check when it comes to ease of development.

Charge storage by gas makes no sense nor does weights.

I agree. But that is not the point. I stated in my write up that those calculations are just to assess how feasible a DoS attack is right now. It is not a long term solution.

Less complex sounds good. Smart contract developers already have the hurdle of getting up to speed with rust. It's one less thing for builders to worry about if they can assume things will always be where they put them.

Maybe we should make old state more costly to retrieve than newer state (if it isn't already)?

If you guys decide to remove rent, I advise to recover put_code
#8671

Yes it can be re-added after this is merged. It is not a priority right now, though.

Maybe we should make old state more costly to retrieve than newer state (if it isn't already)?

We should definitely discuss all the options we have. But this PR is not the right place. FWIW nothing like this is implemented as of right now.

Smart contract developers already have the hurdle of getting up to speed with rust.

For the solidity folks that is true. My hope is that we can get some rustaceans into smart contracts with ink!.

-			return weight_limit
+			return 0


This is a drive by fix. I think this was a refactoring artifact.

 #[derive(Encode, Decode)]
 pub struct DeletedContract {
-	pair_count: u32,


The host API was improved. We no longer need to store how many keys we are deleting because the host API tells us how many where removed.

Looks good to me.

Would be great if you could create a follow-up issue for polkadot-js. AFAIK that's the only UI which displays state rent info.

I propose setting the maximum value size per key to 512 bytes as an initial value (ethereum uses 32 bytes for various reasons).

We should think about warning developers at compile time when using bigger values in ink!. I'll create a follow-up issue once this one is merged.

Simplifying and deleting code FTW

frame/contracts/src/weights.rs

-			.saturating_add((39_799_000 as Weight).saturating_mul(q as Weight))
+		(79_790_000 as Weight)
+			// Standard Error: 2_000
+			.saturating_add((391_000 as Weight).saturating_mul(q as Weight))


Reducing the item size by 4 byte really decreased the decoding time by a lot.

substrate have removed the rent in pallet-contracts in newest substrate after this pr paritytech/substrate#9669. but we do not wanna update current substrate to new version, for we are waiting substrate to release 4.0.0. thus, we just change the rent parameters to zero, it will cause the same result compared with removed rent pallet-contracts.

paritytech/substrate#9669 The concept of paying rent to keep a contract active has been eliminated and the deployer of the Smart Contract just needs to make an extra deposit on trop of the existential deposit.

* Remove ref to Tombstone paritytech/substrate#9669 The concept of paying rent to keep a contract active has been eliminated and the deployer of the Smart Contract just needs to make an extra deposit on trop of the existential deposit. * minor fixes
