    # NEM - Harlock Hardfork Details --- **NOTE** The Harlock hardfork will be executed at block height 3,464,800. ETA: around 18 Nov 2021, 6:00pm UTC --- ### Purpose The ["Harlock"](https://en.wikipedia.org/wiki/Captain_Harlock) hardfork for NEM is intended for users to explicitly signal support for the integration of NEM as a dedicated subChain of Symbol, as proposed [here](https://docs.symbolplatform.com/handbook/en/vision.html). It does so by burning all of the current NEM 'core funds', and minting new funds into a new 5-of-7 multisig account, with four cosigners from [Valkyrie](https://valkyrieinvest.com/) and three core developers. _At and after the Harlock hardfork, all outflows from the following fee sink accounts will be prohibited:_ * Namespace Rental Fee Sink [NAMESPACEWH4MKFMBCVFERDPOOP4FK7MTBXDPZZA](https://explorer.nemtool.com/#/s_account?account=NAMESPACEWH4MKFMBCVFERDPOOP4FK7MTBXDPZZA) * Mosaic Rental Fee Sink [NBMOSAICOD4F54EE5CDMR23CCBGOAM2XSIUX6TRS](https://explorer.nemtool.com/#/s_account?account=NBMOSAICOD4F54EE5CDMR23CCBGOAM2XSIUX6TRS) ### Overview ``` ┌────────────────┐ │ Does 51% of │ ┌──────────Retry─Fork─────────────────►│ harvesting │ │ │ power upgrade? │ │ └──┬────────┬────┘ │ │ │ │ ┌──────────────┐ │ │ ┌───────────────┐ │ │ Do any │ Yes No │ Fork Fails │ │ │ burned funds │◄──────┘ └───────►│ │ │ │ move before │ │ Trust retains │ │ │ fork? │ │ control! │ │ └──┬───────┬───┘ └───────────────┘ ┌─────┴──────────┐ │ │ │ Fallback txes │ Yes No ┌────────────────┐ │ are included │◄─────────┘ └───────►│ Preferred txes │ │ in fork block │ │ are included │ │ │ │ in fork block │ │ Trust retains │ │ │ │ control │ │ Core devs and │ └────────────────┘ │ Valkyrie are │ │ in control! │ └────────────────┘ ``` ### Step Zero: Definitions/Preparation **New Protocol Fund:** Prior to the fork, one new (empty) multisig accounts will need to be created. All newly minted protocol funds will be transfered into this. **NemesisII** Treasury reissuance fork block. ### NemesisII Fork Block At the fork block, a set of predefined TransferTransactions will be sent to the network and harvested by upgraded nodes (v0.6.98). They will be predefined in configuration [1] and will revoke XYM tokens from Trust and NxL owned accounts. In addition, TransferTransactions will be issued from the Nemesis block to the new accounts. [1] The hashes of these special transactions will be listed in the `nis.treasuryReissuanceForkTransactionHashes` property. ### Harvesting Changes (TEMPORARY) **DefaultNewBlockTransactionsProvider:getBlockTransactions** At NemesisII height, retrieve all transactions from UTCache that have a hash in `nis.treasuryReissuanceForkHeight` and order them by TimeStamp. Since there is no state hash, we don't have to worry about corrupting it. **DefaultUnconfirmedState.verifyAndValidate** When a transaction is added to the UTCache, its signature is checked. Bypass this check for any transactions with a hash in `nis.treasuryReissuanceForkTransactionHashes` ### Block Processing Changes #### NemesisSinkValidator Currently, this validator ensures that signatures from the Nemesis Account are only allowed in the Nemesis block. This validator will need to be weakened to allow Nemesis Account signatures in both Nemesis and NemesisII block. #### MinimumFeeValidator NIS does not currently perform full validation on the Nemesis block, so this validator does not properly handle nemesis originating transactions. It needs to be modified to change minimum allowable fee for nemesis originating transactions to zero. #### ReclaimFundsForkTransactionBlockValidator (TEMPORARY) Validates that the block at height `nis.treasuryReissuanceForkHeight` contains exactly all transactions in `nis.treasuryReissuanceForkTransactionHashes`. This will cause a stall until the special transactions are included. #### BlockChainValidator::verifyTransactions Update verification to skip transactions with hashes in `nis.treasuryReissuanceForkTransactionHashes`. This will have some negative performance impact because it will result in an extra hash per transaction. ### Fee Sink Handling **FeeSinkNonOperationalValidator** Since both the namespace and mosaic rental fees sinks are multisig transactions, a new `MultsigTransaction` validator can inspect the transaction's other transaction signer address. If this address matches one of the fee sink accounts, the transaction will be rejected. ### Safety Valve If any of the funds being burned are moved between the release and the NemesisII block, the fork will fail. In order to prevent a catastrophic failure in this case, a set of special fallback transactions [2] can be sent to the network to prevent a catastrophic failure. In the case of failure, the fork could be reattempted at a later date. [2] The hashes of these transactions are specified in the `nis.treasuryReissuanceForkFallbackTransactionHashes` configuration property. ### Appendix: Account Mappings **New Protocol Treasury Account:** [NCHESTYVD2P6P646AMY7WSNG73PCPZDUQNSD6JAK](https://explorer.nemtool.com/#/s_account?account=NCHESTYVD2P6P646AMY7WSNG73PCPZDUQNSD6JAK) ``` NEM Group Trust Addresses ┌──────────────────────────────────────────────────────────────────┐ │ 1.
