Epik changelog

1.4.0 / 2020-12-19

This is a MANDATORY hotfix release of Lotus that resolves a chain halt at height 336,459 caused by nondeterminism in specs-actors. The fix is to update actors to 2.3.3 in order to incorporate this fix filecoin-project/specs-actors#1334.

1.3.0 / 2020-12-16

This is a mandatory release of Lotus that introduces the third post-liftoff upgrade to the Filecoin network. The network upgrade occurs at height 343200, before which time all nodes must have updated to this release (or later). The change that breaks consensus is an implementation of FIP-0009(https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0009.md).

Changes

1.2.3 / 2020-12-15

This is an optional Lotus release that introduces many performance improvements, bugfixes, and UX improvements.

Changes

1.2.2 / 2020-12-03

This is an optional Lotus release that introduces various improvements to the mining logic and deal-making workflow, as well as several new UX features.

Changes

1.2.1 / 2020-11-20

This is a very small release of Lotus that fixes an issue users are experiencing when importing snapshots. There is no need to upgrade unless you experience an issue with creating a new datastore directory in the Lotus repo.

Changes

1.2.0 / 2020-11-18

This is a mandatory release of Lotus that introduces the second post-liftoff upgrade to the Filecoin network. The network upgrade occurs at height 265200, before which time all nodes must have updated to this release (or later). This release also bumps the required version of Go to 1.15.

The changes that break consensus are:

Dependencies

1.1.2 / 2020-10-24

This is a patch release of Epik that builds on the fixes involving worker keys that was introduced in v1.1.1. Miners and node operators should update to this release as soon as possible in order to ensure their blocks are propagated and validated.

Changes

1.1.1 / 2020-10-24

This is a patch release of Epik that addresses some issues caused by when miners change their worker keys. Miners and node operators should update to this release as soon as possible, especially any miner who has changed their worker key recently.

Changes

1.1.0 / 2020-10-20

This is a mandatory release that introduces the first post-liftoff upgrade to the Filecoin network. The changes that break consensus are an upgrade to specs-actors v2.2.0 at epoch 170000.

Changes

1.0.0 / 2020-10-19

It's 1.0.0! This is an optional release of Epik that introduces some UX improvements to the 0.10 series.

This very small release is largely cosmetic, and intended to flag the code that the Filecoin mainnet was launched with.

API changes

  • StateMsgGasCost has been removed. The equivalent information can be gained by calling StateReplay.
  • A GasCost field has been added to the InvocResult type, meaning detailed gas costs will be returned when calling StateReplay, StateCompute, and StateCall.
  • The behaviour of StateReplay in response to an empty tipset key has been changed. Instead of simply using the heaviest tipset (which is almost guaranteed to be an unsuccessful replay), we search now search the chain for the tipset that included the message, and replay the message in that tipset (we fail if no such tipset is found).

Changes

0.10.2 / 2020-10-14

This is an optional release of Epik that updates markets to 0.9.1, which fixes an issue affecting deals that were mid-transfer when the node was upgraded to 0.9.0. This release also includes some tweaks to default gas values and minor performance improvements.

Changes

0.10.1 / 2020-10-14

This is an optional release of Epik that updates markets to 0.9.0, which adds the ability to restart data transfers. This release also introduces Ledger support, and various UX improvements.

Changes

0.10.0 / 2020-10-12

This is a consensus-breaking hotfix that addresses an issue in specs-actors v2.0.3 that made it impossible to pledge new 32GiB sectors. The change in Epik is to update to actors v2.1.0, behind the new network version 5.

Changes

0.9.1 / 2020-10-10

This release fixes an issue which may cause the actors v2 migration to compute the state incorrectly when more than one migration is running in parallel.

Changes

0.9.0 / 2020-10-07

This consensus-breaking release of Epik upgrades the actors version to v2.0.0. This requires migrating actor state from v0 to v2. The changes that break consensus are:

0.7.2 / 2020-09-23

This optional release of Epik introduces a major refactor around how a Epik node interacts with code from the specs-actors repo. We now use interfaces to read the state of actors, which is required to be able to reason about different versions of actors code at the same time.

Additionally, this release introduces various improvements to the sync process, as well as changes to better the overall UX experience.

This patch release includes some bugfixes and enhancements to the sector lifecycle and message pool logic.

Changes

0.5.6 / 2020-08-29

Hotfix release that fixes a panic in the sealing scheduler (https://github.com/EpiK-Protocol/go-epik/pull/3389).

0.5.5

This patch release introduces a large number of improvements to the sealing process. It also updates go-fil-markets to version 0.5.8, and go-libp2p-pubsub to v0.3.5.

Downstream upgrades

Sector sealing

  • The following improvements were introduced in https://github.com/EpiK-Protocol/go-epik/pull/3350.

    • Allow epik-miner sectors remove to remove a sector in any state.
    • Create a separate state in the storage FSM dedicated to submitting the Commit message.
    • Recovery for when the Deal IDs of deals in a sector get changed in a reorg.
    • Auto-retry sending Precommit and Commit messages if they run out of gas
    • Auto-retry sector remove tasks when they fail
    • Compact worker windows, and allow their tasks to be executed in any order

  • Don't simply skip PoSt for bad sectors (https://github.com/EpiK-Protocol/go-epik/pull/3323)

Message Pool

Chainwatch

0.5.4

A patch release, containing a few nice bugfixes and improvements:

  • Fix parsing of peer ID in epik-miner actor set-peer-id (@whyrusleeping)
  • Update dependencies, fixing several bugs (@Stebalien)
  • Fix remaining linter warnings (@Stebalien)
  • Use safe string truncation (@Ingar)
  • Allow tweaking of blocksync message window size (@whyrusleeping)
  • Add some additional gas stats to metrics (@Kubuxu)
  • Fix an edge case bug in message selection, add many tests (@vyzo)

0.5.3

Yet another hotfix release. A lesson for readers, having people who have been awake for 12+ hours review your hotfix PR is not a good idea. Find someone who has enough slept recently enough to give you good code review, otherwise you'll end up quickly bumping versions again.

  • Fixed a bug in the mempool that was introduced in v0.5.2

0.5.2 / 2020-08-24

This is a hotfix release.

  • Fix message selection to not include messages that are invalid for block inclusion.
  • Improve SelectMessage handling of the case where the message pools tipset differs from our mining base.

0.5.1 / 2020-08-24

The Space Race release! This release contains the genesis car file and bootstrap peers for the space race network.

Additionally, we included two small fixes to genesis creation:

  • Randomize ticket value in genesis generation
  • Correctly set t099 (burnt funds actor) to have valid account actor state

0.5.0 / 2020-08-20

This version of Epik will be used for the incentivized testnet Space Race competition, and can be considered mainnet-ready code. It includes some protocol changes, upgrades of core dependencies, and various bugfixes and UX/performance improvements.

Highlights

Among the highlights included in this release are:

  • Gas changes: We implemented EIP-1559 and introduced real gas values.
  • Deal-making: We now support "Committed Capacity" sectors, "fast-retrieval" deals, and the packing of multiple deals into a single sector.
  • Renamed features: We renamed some of the binaries, environment variables, and default paths associated with a Epik node.

Gas changes

We made some significant changes to the mechanics of gas in this release.

Network fee

We implemented something similar to Ethereum's EIP-1559. The Message structure had three changes:

  • The GasPrice field has been removed
  • A new GasFeeCap field has been added, which controls the maximum cost the sender incurs for the message
  • A new GasPremium field has been added, which controls the reward a miner earns for including the message

A sender will never be charged more than GasFeeCap * GasLimit. A miner will typically earn GasPremium * GasLimit as a reward.

The Blockheader structure has one new field, called ParentBaseFee. Informally speaking,the ParentBaseFee is increased when blocks are densely packed with messages, and decreased otherwise.

The ParentBaseFee is used when calculating how much a sender burns when executing a message. Burning simply refers to sending attoEPK to a dedicated, unreachable account. A message causes ParentBaseFee * GasUsed attoEPK to be burnt.

Real gas values

This release also includes our first "real" gas costs for primitive operations. The costs were designed to account for both the time that message execution takes, as well as the space a message adds to the state tree.

Deal-making changes

There are three key changes to the deal-making process.

Committed Capacity sectors

Miners can now pledge "Committed Capacity" (CC) sectors, which are explicitly stated as containing junk data, and must not include any deals. Miners can do this to increase their storage power, and win block rewards from this pledged storage.

They can mark these sectors as "upgradable" with epik-miner sectors mark-for-upgrade. If the miner receives and accepts one or more storage deals, the sector that includes those deals will replace the CC sector. This is intended to maximize the amount of useful storage on the Filecoin network.

Fast-retrieval deals

Clients can now include a fast-retrieval flag when proposing deals with storage miners. If set to true, the miner will include an extra copy of the deal data. This data can be quickly served in a retrieval deal, since it will not need to be unsealed.

Multiple deals per sector

Miners can now pack multiple deals into a single sector, so long as all the deals fit into the sector capacity. This should increase the packing efficiency of miners.

Renamed features

To improve the user experience, we updated several names to mainatin standard prefixing, and to better reflect the meaning of the features being referenced.

In particular, the Epik miner binary is now called epik-miner, the default path for miner data is now ~/.epikminer, and the environment variable that sets the path for miner data is now $EPIK_MINER_PATH. A full list of renamed features can be found here.
