+
+### Clique/PoA Support
+
+This release introduces Clique/PoA support for the `Block` library, see the main PR [#1032](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1032) as well as the follow-up PRs [#1074](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1074) and PR [#1088](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1088). The `BlockHeader.validate()` function now properly validates the various Clique/PoA-specific properties (`extraData` checks and others, see API documentation) and `BlockHeader.validateConsensus()` can be used to properly validate that a Clique/PoA block has the correct signature.
+
+For sealing a block on instantiation there is a new `cliqueSigner` constructor option:
+
+```typescript
+const cliqueSigner = Buffer.from('PRIVATE_KEY_HEX_STRING', 'hex')
+const block = Block.fromHeaderData(headerData, { cliqueSigner })
+```
+
+Additionally there are the following new utility methods for Clique/PoA related functionality in the `BlockHeader` class:
+
+- `BlockHeader.validateCliqueDifficulty(blockchain: Blockchain): boolean`
+- `BlockHeader.cliqueSigHash()`
+- `BlockHeader.cliqueIsEpochTransition(): boolean`
+- `BlockHeader.cliqueExtraVanity(): Buffer`
+- `BlockHeader.cliqueExtraSeal(): Buffer`
+- `BlockHeader.cliqueEpochTransitionSigners(): Address[]`
+- `BlockHeader.cliqueVerifySignature(signerList: Address[]): boolean`
+- `BlockHeader.cliqueSigner(): Address`
+
+See the API docs for a detailed documentation. Note that these methods will throw if called in a non-Clique/PoA context.
+
+### Other Changes
+
+- The `Common` instance passed is now copied to avoid side-effects towards the outer common instance on HF updates, PR [#1089](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1089)
+- Fixed a bug where txs have been created with the wrong HF when `hardforkByBlockNumber` is used along with the static constructors, PR [#1089](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1089)
+- Fixed a bug where `Common` has not been passed to the returned block in the `blockFromRpc()` method, PR [#1032](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1032)

+# CONSENSUS TYPES
+
+The block library supports the creation as well as format and consensus validation of PoW `ethash` and PoA `clique` blocks.
+
+## Ethash/PoW
+
+An Ethash/PoW block can be instantiated as follows:
+
+```typescript
+import { Block } from '@ethereumjs/block'
+import Common from '@ethereumjs/common'
+const common = new Common({ chain: 'mainnet' })
+console.log(common.consensusType()) // 'pow'
+console.log(common.consensusAlgorithm()) // 'ethash'
+const block = Block.fromBlockData({}, { common })
+```
+
+To validate that the difficulty of the block matches the canonical difficulty use `block.validate(blockchain)`.
+
+To calculate the difficulty when creating the block pass in the block option `calcDifficultyFromHeader` with the preceding (parent) `BlockHeader`.
+
+## Clique/PoA (since v3.1.0)
+
+A clique block can be instantiated as follows:
+
+```typescript
+import { Block } from '@ethereumjs/block'
+import Common from '@ethereumjs/common'
+const common = new Common({ chain: 'goerli' })
+console.log(common.consensusType()) // 'poa'
+console.log(common.consensusAlgorithm()) // 'clique'
+const block = Block.fromBlockData({}, { common })
+```
+
+For clique PoA `BlockHeader.validate()` function validates the various Clique/PoA-specific properties (`extraData` checks and others, see API documentation) and `BlockHeader.validateConsensus()` can be used to properly validate that a Clique/PoA block has the correct signature.
+
+For sealing a block on instantiation you can use the `cliqueSigner` constructor option:
+
+```typescript
+const cliqueSigner = Buffer.from('PRIVATE_KEY_HEX_STRING', 'hex')
+const block = Block.fromHeaderData(headerData, { cliqueSigner })
+```
+
+Additionally there are the following utility methods for Clique/PoA related functionality in the `BlockHeader` class:
+
+- `BlockHeader.validateCliqueDifficulty(blockchain: Blockchain): boolean`
+- `BlockHeader.cliqueSigHash()`
+- `BlockHeader.cliqueIsEpochTransition(): boolean`
+- `BlockHeader.cliqueExtraVanity(): Buffer`
+- `BlockHeader.cliqueExtraSeal(): Buffer`
+- `BlockHeader.cliqueEpochTransitionSigners(): Address[]`
+- `BlockHeader.cliqueVerifySignature(signerList: Address[]): boolean`
+- `BlockHeader.cliqueSigner(): Address`
+
+See the API docs for detailed documentation. Note that these methods will throw if called in a non-Clique/PoA context.

 # TESTING
 
 Tests in the `tests` directory are partly outdated and testing is primarily done by running the `BlockchainTests` from within the [ethereumjs-vm](https://github.com/ethereumjs/ethereumjs-vm/tree/master/packages/vm#synopsis) package.

 Validates the block header, throwing if invalid. It is being validated against the reported `parentHash`.
 It verifies the current block against the `parentHash`:
 - The `parentHash` is part of the blockchain (it is a valid header)
 - Current block number is parent block number + 1
 - Current block has a strictly higher timestamp
-- Current block has valid difficulty and gas limit
-- In case that the header is an uncle header, it should not be too old or young in the chain.

+  - Current block has valid difficulty and gas limit
+  - In case that the header is an uncle header, it should not be too old or young in the chain.
+- Additional PoA clique checks ->
+  - Various extraData checks

+  - Current block has a timestamp diff greater or equal to PERIOD
+  - Current block has difficulty correctly marked as INTURN or NOTURN

 Validates the block header, throwing if invalid. It is being validated against the reported `parentHash`.
 It verifies the current block against the `parentHash`:
 - The `parentHash` is part of the blockchain (it is a valid header)
 - Current block number is parent block number + 1
 - Current block has a strictly higher timestamp
-- Current block has valid difficulty and gas limit
-- In case that the header is an uncle header, it should not be too old or young in the chain.
+- Additional PoW checks ->
+  - Current block has valid difficulty and gas limit
+  - In case that the header is an uncle header, it should not be too old or young in the chain.
+- Additional PoA clique checks ->
+  - Various extraData checks
+  - Checks on coinbase and mixHash
+  - Current block has a timestamp diff greater or equal to PERIOD
+  - Current block has difficulty correctly marked as INTURN or NOTURN

+### Clique/PoA Support
+
+This release introduces Clique/PoA support for the `Blockchain` library, see the main PR [#1032](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1032) as well as the follow-up PRs [#1074](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1074) and PR [#1088](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1088).
+
+The blockchain package now keeps track of the latest signers and votes on new Clique/PoA signers and saves them to DB. Block format validation is now also taking all the Clique/PoA specifics into account (`extraData` format and other formal requirements from the EIP) and consensus validation is now also working for Clique/PoA chains (this verifies the respective block signatures from the corresponding authorized signers) and can be activated with the `validateConsensus` constructor flag. There is a new public method `Blockchain.cliqueActiveSigners()` to get the currently active signer list.
+
+### Other Features/Changes
+
+- Added optional `maxBlocks` parameter to `Blockchain.iterator()` method, PR [#965](https://github.com/ethereumjs/ethereumjs-monorepo/pull/965)
+- `Blockchain.iterator()` now returns a `number` (instead of `void`) with the blocks actually iterated (the `Blockchain` interface allows for both for backwards-compatibility reasons for now, `void` is considered deprecated though), PR [#1065](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1065)
+- Blocks in the blockchain package are now always created with the `hardforkByBlockNumber` option set to `true` to avoid inconsistencies in block behavior, PR [#1089](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1089)
+- New `Blockchain.setHead(tag: string, headHash: Buffer)` method to set a specific iterator head to a certain block, PR [#965](https://github.com/ethereumjs/ethereumjs-monorepo/pull/965)
+- Added `debug` logger integration, first `blockchain:clique` debug logger (see README), PR [#1103](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1103)
+- Fixed a bug in the validation logic to only validate the block header if a header is passed to the internal `Blockchain._putBlockOrHeader()` function, PR [#1105](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1105)

+## 2.1.0 - 2021-02-22
+
+### Clique/PoA Support
+
+This release completes on Clique/PoA support (see also Clique/PoA related changes in `v2.0.0`), see PR [#1032](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1032). The chain configuration files (e.g. `chains/goerli.json`) are extended by a consensus algorithm-specific config parameter section, here is a sample `consensus` parameter section, note that the `config` parameter dict must be named after the consensus algorithm:
+
+```json
+{
+  "consensus": {
+    "type": "poa",
+    "algorithm": "clique",
+    "clique": {
+      "period": 15,
+      "epoch": 30000
+    }
+  }
+}
+```
+
+For now this is done in a backwards-compatible way and the `consensus` parameter section is still marked as optional. You nevertheless might want to add this section already to your custom chain files - even if you don't make usage of the parameters - to remain compatible in the future.
+
+The new parameter section is complemented by a new `Common.consensusConfig()` function to request these parameters in addition to the `Common.consensusType()` and `Common.consensusAlgorithm()` methods introduced in `v2.0.0`.
+
+### Custom Chain File Support
+
+There is now a more convenient and flexible way to integrate custom chains into Common instances complementing the existing `Common.fromCustomChain()` static constructor, see PR [#1034](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1034).
+
+This new way adds a new `customChains` constructor option and can be used as following:
+
+```typescript
+import myCustomChain1 from './[PATH]/myCustomChain1.json'
+import myCustomChain2 from './[PATH]/myCustomChain2.json'
+// Add two custom chains, initial mainnet activation
+const common1 = new Common({ chain: 'mainnet', customChains: [ myCustomChain1, myCustomChain2 ] })
+// Somewhat later down the road...
+common1.setChain('customChain1')
+// Add two custom chains, activate customChain1
+const common1 = new Common({ chain: 'customChain1', customChains: [ myCustomChain1, myCustomChain2 ] })
+```
+
+The [README section](https://github.com/ethereumjs/ethereumjs-monorepo/tree/master/packages/common#working-with-privatecustom-chains) on working with custom chains has been significantly expanded along the way and is a recommended read if you use common for custom chain initialization.
+
+### New EIPs
+
+#### EIP-1459 DNS Peer Discovery
+
+[EIP-1459](https://eips.ethereum.org/EIPS/eip-1459) introduces a way to discover nodes for an Ethereum network connection via DNS. This release adds a new optional chain config file parameter `dnsNetworks` and an associated method `Common.dnsNetworks()` to request DNS networks for a chain.
+
+#### EIP-2565 ModExp Precompile Gas Costs
+
+[EIP-2565](https://eips.ethereum.org/EIPS/eip-2565) introduces a new algorithm for ModExp precompile gas cost calculation. A new EIP file `eips/2565.json` has been added along the work on PR [#1026](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1026) with respective parameter updates.
+
+### Other Changes
+
+- `Common` is now implemented as an `EventEmitter` and emits a `hardforkChanged` event upon a HF change, PR [#1112](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1112)
+- New `Common.isActivatedEIP()` method, PR [#1125](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1125)
+- Updated `Goerli` bootnodes, PR [#1031](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1031)

 Follow-up release on `v3.0.1` which only partly addressed a **critical** bug. An update is - again - strongly recommended.

+- The `Common` instance passed is now copied to avoid side-effects towards the outer common instance on HF updates, PR [#1088](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1088)

+This release introduces Clique/PoA support, see the main PR [#1032](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1032) as well as the follow-up PRs [#1074](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1074) and PR [#1088](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1088). This means that you now can run a VM with blocks or transactions from the main PoA networks `Goerli` and `Rinkeby` and generally can use the VM in a Clique/PoA context.
+
+Here is a simple example:
+
+```typescript
+import VM from '@ethereumjs/vm'
+import Common from '@ethereumjs/common'
+
+const common = new Common({ chain: 'goerli' })
+const hardforkByBlockNumber = true
+const vm = new VM({ common, hardforkByBlockNumber })
+
+const serialized = Buffer.from('f901f7a06bfee7294bf4457...', 'hex')
+const block = Block.fromRLPSerializedBlock(serialized, { hardforkByBlockNumber })
+const result = await vm.runBlock(block)
+```
+
+All the corresponding internal dependencies have been updated to Clique/PoA supporting versions, namely:
+
+- @ethereumjs/block -> `v3.1.0`
+- @ethereumjs/blockchain -> `v5.1.0`
+- @ethereumjs/common" -> `v2.1.0`
+
+Note that you need to also use library versions equal or higher than the ones mentioned above when you pass in an instance from one of the libraries to an API call (e.g. `VM.runBlock()`, see example above) to ensure everything is working properly in a Clique/PoA context.
+
+New VM behavior in a Clique/PoA context:
+
+- `VM.runBlock()`: If you do block validation along block runs blocks are now validated to comply with the various Clique/PoA block format specifications (various `extraData` checks e.g.)
+- `VM.runBlock()`: There is no assignment of block rewards to the `coinbase` account taking place
+- `VM.runTx()`: Tx fees are attributed to the block signer instead of the `coinbase` account
+- `COINBASE` opcode: The `COINBASE` opcode returns the block signer instead of the `coinbase` address (Clique specification)
+
+### StateManager Checkpointing Performance
+
+This is the first release which reliably exposes performance gains on all checkpointing operations by integrating the respective `merkle-patricia-trie` [v4.1.0](https://github.com/ethereumjs/ethereumjs-monorepo/releases/tag/merkle-patricia-tree%404.1.0) where the checkpointing mechanism has been reworked substantially.
+
+This leads to linearly growing performance gains on all checkpointing operations (in `VM.runBlock()`, `VM.runTx()` as well as along all `message` calls) along with the size of the trie (state) being operated upon. In practice we have seen 10-50x increases when working on blocks from `mainnet` or the other test networks.
+
+We would be happy on some feedback if this integration is noticeable in your execution context! 😀
+
+### New EIPs
+
+#### EIP-2565: ModExp precompile gas cost
+
+This release adds support for [EIP 2565](https://eips.ethereum.org/EIPS/eip-2565), ModExp precompile gas cost, which is planned to be included in the Berlin hardfork, see PR [#1026](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1026).
+
+#### VM Debug Logger
+
+The VM now comes with an integrated debug logger which gives you fine-grained control to display selected log output along the VM execution flow, see PR [#1080](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1080). These loggers use the [debug](https://github.com/visionmedia/debug) library and can be activated on the CL with `DEBUG=[Logger Selection] node [Your Script to Run].js` and produce output like the following:
+
+![EthereumJS VM Debug Logger](./debug.png?raw=true)
+
+For an overview on the different loggers available see the respective [README section](https://github.com/ethereumjs/ethereumjs-monorepo/tree/master/packages/vm#understanding-the-vm).
+
+### Other Features
+
+- The `afterBlock` (`VM.runBlock()`) and `afterTx` (`VM.runTx()`) events now expose the respective block or transaction in the event results, PR [#965](https://github.com/ethereumjs/ethereumjs-monorepo/pull/965)
+- New `hardforkByBlockNumber` VM constructor option for `VM.runBlock()` runs (see also corresponding `Block` option), PR [#966](https://github.com/ethereumjs/ethereumjs-monorepo/pull/966) and [#967](https://github.com/ethereumjs/ethereumjs-monorepo/pull/967) (option renamed along release PR)
+- Added new optional `maxBlocks` option to `VM.runBlockchain()`, PR [#1025](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1025)
+- `VM.runBlockchain()` now returns the number of actual blocks run (needs `Blockchain` `v5.1.0` or higher, `void` kept in `TypeScript` function signature for backwards-compatibility), PR [#1065](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1065)
+- New option `skipBlockGasLimitValidation` to disable the block gas limit check in `VM.runTx()`, PR [#1039](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1039)
+- Added type definition `Log` for logs in `TxReceipt` items returned (result of `VM.runBlocks()` and `afterBlock` event), PR [#1084](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1084)
+
+### Bug Fixes
+
+- **Consensus**: fixed `Frontier` consensus bug along `CREATE` with not enough gas, PR [#1081](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1081)
+- Update opcodes along HF switches, added a dedicated `tangerineWhistle` opcode list (no need for calls to `VM._updateOpcodes()` on HF switches manually any more), PR [#1101](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1101) and [#1112](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1112)
+- Use `common` from VM when creating default blocks in `VM.runCall()` and `VM.runCode()`, PR [#1011](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1011)
+- Fixed a bug when the result of the `MODEXP` opcode is 0, PR [#1026](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1026)
+
+### Maintenance
+
+- Updated `run-solidity-contract` example, PR [#1104](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1104)
+- Updated `ethereum/tests` submodule to `1fcd4e5` (2021-02-02), PR [#1116](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1116)
+- Only expose API method on docs, PR [#1119](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1119)

 # SETUP
 
+## Chain Support
+
+Starting with `v5.1.0` the VM supports running both `Ethash/PoW` and `Clique/PoA` blocks and transactions. Clique support has been added along the work on PR [#1032](https://github.com/ethereumjs/ethereumjs-monorepo/pull/1032) and follow-up PRs and (block) validation checks and the switch of the execution context now happens correctly.
+
+### Ethash/PoW Chains
+
+`@ethereumjs/blockchain` validates the PoW algorithm with `@ethereumjs/ethash` and validates blocks' difficulty to match their canonical difficulty.
+
+### Clique/PoA Chains
+
+For the VM to work correctly in a `Clique/PoA` context you need to use the library with the following library versions or higher:
+
+- @ethereumjs/block -> `v3.1.0`
+- @ethereumjs/blockchain -> `v5.1.0`
+- @ethereumjs/common" -> `v2.1.0`
+
+The following is a simple example for a block run on `Goerli`:
+
+```typescript
+import VM from '@ethereumjs/vm'
+import Common from '@ethereumjs/common'
+
+const common = new Common({ chain: 'goerli' })
+const hardforkByBlockNumber = true
+const vm = new VM({ common, hardforkByBlockNumber })
+
+const serialized = Buffer.from('f901f7a06bfee7294bf4457...', 'hex')
+const block = Block.fromRLPSerializedBlock(serialized, { hardforkByBlockNumber })
+const result = await vm.runBlock(block)
+```
+
 ## Hardfork Support
 
 Starting with the `v5` release series all hardforks from `Frontier` (`chainstart`) up to the latest active mainnet hardfork are supported.
