What is this?

This is a deep-dive on the Swarm Storage Incentives. Contained within is guidance on how to optimise performance in the "Schelling Game" - the core component of the storage incentives. The article includes details for using tools to optimise this performance. There is NO tl;dr - understanding how to optimise performance REQUIRES knowledge of some Swarm primitives. If you're in for the long haul, read on enthusiastic bee 🐝...

Primitives

Storage (Chunks)

When uploading data to Swarm, end users may think of "files", but this is NOT how Swarm works (contrary to the likes of IPFS). Swarm will take a file and break it into chunks of 4KB, similar to how when writing to storage in a computer your file is actually stored over a number of sectors on disk.

Unlike disk-sectors that are sequentially addressed, a chunk is addressed by it's cryptographic hash. This is known as the chunk's content address, and looks something like: 9c22ff5f21f0b81b113e63f7db6da94fedef11b2119b4088b89664fb9a3cb658.

Nodes

In order to store data, and to do so in a privacy preserving, censorship-resistant manner, with data-redundancy and availability guarantees requires a set of nodes to co-operate based on protocols. Collectively these protocols are what define Swarm, and the reference implementation of these protocols is bee.

Each node is identified in Swarm by it's overlay address. From the bee source code, it can be determined that an overlay address O is defined as:

O = H(ethAddr . netIdBytes .nonce)

In practice, this looks something like: 9c0d5eba6c3c1c59233066c6004e92c8b693846f351f5083a2f75a1d4718969d

How does a node know what to store?

In Swarm, nodes are grouped into neighbourhoods, which determine:

  1. What nodes they will prefer for connectivity (their neighbours).

  2. What chunks fall into their area of responsibility - these are the chunks that nodes MUST store (the node's store is also known as the reserve).

To determine the node's neighbourhood, and also who it's neighbours are, the node needs to get some idea as to just how much data is in the Swarm.

Storage Radius

The storage radius is a number representing the number of leading bits used when comparing the node's overlay address and a chunk's content address that form it's area of responsibility / neighbourhood.

Example: Overlay address O: 9c0d5eba6c3c1c59233066c6004e92c8b693846f351f5083a2f75a1d4718969d Storage radius r: 8
Neighbourhood prefix (the first 8 bits, taken from the storage radius): 9c Total number of neighbourhoods: 256 (n = 2^r)

Therefore, this node must synchronise all chunks whose content address begins with 9c, such as the previously mentioned example chunk!

A node will attempt to fill it's reserve to at least 40% capacity (nominally the reserve has a maximum capacity of 4M chunks, or ~15.25GB). To do this, the node first "warms up", connecting to other nodes to build a reasonable guess of the Swarm's size. This guess is based on the distribution of the other nodes that the node is connected to. Now, from this guess, the node will begin synchronising historical chunks using the pullsync protocol.

CAUTION: Above capacity statements are targets for the node and do not include other data stored (such as database indexes, statestore etc) and should NOT be used as guidance for determining maximum bee node storage. In practice, you should allow conservatively up to 60GB, though the node may use considerably less.

Pull sync

If the node started with a storage radius below the swarm's average, it will pull in more chunks than required, resulting in the reserve exceeding 100% capacity. At this point, the pullsync will increase the storage radius, and trim the chunks from the reserve that are no longer within the new storage radius.

If the node started with a storage radius above the swarm's average, it will pull in less chunks than required to fill the reserve to at least 40% capacity. As the chunk-sync rate falls to 0 chunks/sec, the pullsync will decrease the storage radius, pulling in more chunks within the new storage radius.

The above logic will iteratively continue until the node arrives at the target reserve capacity (40% - 100%), and therefore settle on the Swarm's average storage radius.

Postage Stamps

Great! We can now pull down all these chunks, but how does a node know what is real, genuine data that should be stored in the Swarm? This is where Postage Stamps come in. These are analogous to stamps placed on old-school snail mail βœ‰οΈ, instructing the postal service that "this envelope is real and should have a service applied to it". When a user uploads data to Swarm, they attach a stamp to this data that they purchased with BZZ.

The postage stamps have two properties of interest to the Swarm: the volume of data that the stamp can be attached to, and the value, how long the Swarm should keep the data for. The stamp's value is analogous to rent (time) for a fixed volume of data on Swarm. The price of this rent is set by a PriceOracle, and the fee is denominated in PLUR (the smallest unit of BZZ). You can top up a stamp, which extends it's validity (time-to-live, or TTL), and you can also increase depth, which increases the volume of data you can store with that stamp (but results in a corresponding decrease in length of validity).

It is this rent charged via stamps that undergoes redistribution to node operators to subsidise / incentivise them to house your data - but be careful to pay your rent (top up your stamp) - otherwise your data may be evicted from it's home on the Swarm!

Phew, that's a lot to get here. The good news is, we're done on the primitives required to understand the storage incentives. Good work! πŸ’ͺ

Storage Incentives

With the release of bee v1.11.0, storage incentives were activated. These incentives are implemented using a coordination game. Broadly speaking:

  1. Every 12 mins 40 seconds (or 152 blocks @ a block time of 5s for Gnosis Chain), staked nodes in a random neighbourhood participate in the coordination game.

  2. In the commit phase, each node in the neighbourhood commits an obfuscated hash of it's reserve to the blockchain. It's obfuscated so other nodes cannot cheat from it.

  3. In the reveal phase, each node reveals their non-obfuscated hash (which is checked against their previous commit).

  4. In the claim phase, a random node is chosen to be a "truth teller". From the nodes who told this truth a random node is selected as the winner (biased towards their stake density - the amount they have staked), and the accumulated rent is transferred from the PostageStamp contract to the winner. All nodes whose hash didn't match the truth are frozen. A new random neighbourhood is chosen at this time so that nodes can begin calculating their reserve's hash before the start of the next round's commit phase.

From the above game, the following conclusions can be made:

  1. A node has an average 1/n chance of having it's neighbourhood selected for playing a round, where n = 2^r and r = storage radius.

    Example
    Storage radius r = 8
    Number of neighbourhoods: n = 2^r = 2^8 = 256
    P(Neighbourhood Chosen) = 1/n = 1/2^r = 1/256
    Round length (seconds): l = 760
    Average neighbourhood selection frequency: f = P(Neighbourhood Chosen) / l = 1 / 256 / 760 β‰ˆ 54 hrs

    Therefore, a node can expect their neighbourhood to be selected on average every ~54 hrs.

  2. The randomness at which a node's neighbourhood is chosen means a node should stay online as continuously as possible to maximise it's likelihood of being available to play.

  3. The chance of a node winning is relative to it's stake density, versus the average stake density in the neighbourhood. It is ideal to find a neighbourhood with as few neighbours as possible to minimise competition.

    Example
    Storage radius: r = 8
    P(Neighbourhood Chosen) = 1/256
    Number of neighbours: p = 5
    P(Node win) = P(Neighbourhood Chosen) / p = 1 / 2^r p = 1 / (256 x 5) = 1 / 1280
    Average node win frequency: f(w) = P(Node win) / l = 1 / 1280 x 760 β‰ˆ 270 hrs

  4. When choosing an amount to stake for a new node, it is sound to start with with a stake equal to the average within a neighbourhood. This is the classic Prisoner's dilemma.

  5. The reward expected for each round depends on the postage stamp price and the total amount of data paid for in current stamps.

    Example
    Postage Price = 24000 PLUR
    Total chunks paid for = 11401m
    Round reward: i = Price x Number of chunks x Round length
    i = 24000 x 11401000000 x 152 / 10^16 β‰ˆ 4.159 BZZ

    NOTE: It is possible that users may purchase very large postage stamps (in the terabytes of data or more), but not utilise them completely. In which case, they are effectively paying rent for something that they are not occupying / utilising. This gives rise to the expected phenomenon that Actual Storage ≀ Paid Storage.

Optimisation

If you've made it to this point, you will by now know that the only thing within your control to optimise performance in the Schelling game is through minimising your competition, and staking the average within your neighbourhood. Fortunately, unlike with most situations in life - in this case we can choose our neighbourhood!

We will use the following algorithm to determine which neighbourhood to mine an address to:

  1. Retrieve the previous day's average depth reported to the Redistribution contract (Schelling game).

  2. Retrieve all the currently staked nodes' overlay addresses.

  3. From (1), determine the number of neighbourhoods and using the list in (2) sort these by neighbourhood, determining which neighbourhood/s has the lowest population.

  4. Choose a random neighbourhood from the list from (3) if there is more than 1 neighbourhood.

  5. If there are already nodes within the neighbourhood, search within that neighbourhood at depth + 1 so that in the future if the neighbourhood splits, your node is now with reduced, or no competition.

  6. Mine an overlay address to the chosen neighbourhood and depth.

Mining overlay addresses

From the bee source code, it can be determined that an overlay address O is defined as:

O = H(ethAddr.netIDBytes.nonce)

The netIDBytes corresponds to the Swarm network ID, and the nonce is for legacy bee nodes that were migrated from pre v1.11.0. For new bee nodes, nonce is set to 32 bytes of 0 (ie. solidity type bytes32(0)).

Using this knowledge, it is possible to iterate through Ethereum addresses, mining (guessing) for an Ethereum address that corresponds to an overlay prefix that may be desired.

Swarm Tools 🧰

Researching all of the above led to the creation of swarm-tools-rs, a CLI application written in rust πŸ¦€. This tool follows conventional command-line interface design.

Requirements

  1. Your own Gnosis Chain RPC. swarm-tools-rs makes heavy use of RPC calls. IT IS STRONGLY RECOMMENDED TO RUN THIS WITH YOUR OWN RPC.

  2. A familiarity with command line environments on your operating system.

  3. An understanding of the above content so you have a better idea as to what you're doing πŸ˜ƒ.

Installation

Release binaries are built for:

  1. Linux

  2. Mac OS X (Darwin)

  3. Windows

You can get the relevant release binaries from the swarm-tools-rs repository.

Game Analysis

OK, let's have a look at the distribution of nodes in the game:

$ swarm-tools --gnosis-rpc ws://your-gnosis-rpc-here:8545 game -r 8 > output.txt

The above command:

  1. Sets the Gnosis Chain RPC to ws://your-gnosis-rpc-here:545

  2. Analyses the game using a storage radius of 8.

  3. Outputs all the diagnostics data to output.txt

This will print out a CSV of all the Staked Players in the game, including their stake, and neighbourhood calculated with the specified storage radius. From here, you can import this CSV data into data visualisation tools / spreadsheet software to visualise the distribution of nodes within the game.

There will also be overview statistics output:

Total players: 1986
Total stake: 220633333000071328010
Average stake: 111094326787548503
Average neighbourhood population: 7
Lowest neighbourhoods: (4, [129, 185, 79, 215, 36, 97, 157, 104, 191, 147, 94, 254, 253, 64, 18, 125, 146, 93, 139, 133, 202, 175, 57])
Optimum neighbourhood: (10, 379)

The stake values above are in in PLUR (ie. atomic BZZ). The neighbourhoods with the lowest population (4) are [129, 185, 79, 215, 36, 97, 157, 104, 191, 147, 94, 254, 253, 64, 18, 125, 146, 93, 139, 133, 202, 175, 57] (ie. there are 23 neighbourhoods with a population of 4), and the optimum neighbourhood has been determined as neighbourhood 379 at a radius of 10 (this corresponds to neighbourhood 94 at a radius of 8).

Mining overlay addresses ⛏️

WARNING: After mining your overlays you should Stake them as soon as possible. As neighbourhood selection is deterministic, other apiarists may be mining into your neighbourhood as you read!

OK, OK. You're sick of theory. Let's automate this! πŸ€– You are a budding apiarist, and want to build your hive!

How big a hive do you want? Let's say you want 20 bees 🐝🍯:

The above command will:

  1. Automatically work out the game's current storage radius.

  2. Iteratively find the optimum neighbourhoods for the number of nodes you desire.

  3. Place the nodes' corresponding encrypted JSON wallet and password in the bees folder in the current working directory.

Funding your nodes

Now that you have generated the wallets / overlays for the bees that constitute your new hive, it's best to stake these as soon as possible! Fortunately there's a wallet tool built right in to do this.

Architecture

The wallet funding system in swarm-tools-rs makes use of:

  1. A "funding wallet", which is a normal encrypted JSON wallet stored under the wallet.json in the bees directory.

  2. A Safe (formerly Gnosis Safe) that is deployed to Gnosis Chain to enable multiplexing of transactions for better gas efficiency / atomic transactions.

Before any initial use of the wallet functions, the funding wallet will be automatically generated and it will prompt you to fund it using the faucet. Just follow the prompts!

In the above, the tool has determined the average neighbourhood stake and specified this as the starting stake for the new nodes. You may run the command again with the -m 100000000000000000 option which will limit the maximum amount of BZZ for each node to 10 BZZ.

Follow the on-screen prompts. Once the token bridging is started, it may take up to ~10 mins for the tokens to be bridged at which point it will commence prompting you with the same prompts you will find below in "From Gnosis Chain", though you won't have to execute the command to commence funding (as it's already running!).

From Gnosis Chain

The below example assumes that the funding wallet on Gnosis Chain already has the required xDAI (1 xDAI per node) and that the Safe has the required xBZZ. If these requirements aren't met, you will be prompted.

Congratulations, your new nodes are now staked!! πŸ₯³πŸŽ‰

Running your new bee nodes

Now that your nodes are fully funded, and staked, it is a great time to actually getting around to running your nodes!

In the bees sub-directory where the swarm-tools application was run, you will find the encrypted JSON and passwords for the nodes' wallets.

To configure a bee node:

  1. Copy the wallet to a NEW bee installation.
cp ./bees/00112233445566778899aabbccddeeff00112233445566778899aabbccddeeff.json /path/to/bee/dir/keys/swarm.key
cp ./bees/00112233445566778899aabbccddeeff00112233445566778899aabbccddeeff.password /path/to/bee/dir/password
  1. Set the password-file option for bee to specify the path to the password file.

Sweep your Profit πŸ€‘

You can use swarm-tools to bulk transfer all your nodes' profits back to your Safe:
