## Signature production and verification for spec types - for every type of
## signature, there are 3 functions:
## * `compute_*_signing_root` - reduce message to the data that will be signed
## * `get_*_signature` - sign the signing root with a private key
## * `verify_*_signature` - verify a signature produced by `get_*_signature`
##
## See also `signatures_batch` for batch verification versions of these
## functions.

rework spec imports (#2779) The spec imports are a mess to work with, so this branch cleans them up a bit to ensure that we avoid generic sandwitches and that importing stuff generally becomes easier. * reexport crypto/digest/presets because these are part of the public symbol set of the rest of the spec types * don't export `merge` types from `base` - this causes circular deps * fix circular deps in `ssz/spec_types` - this is the first step in disentangling ssz from spec * be explicit about phase0 vs altair - longer term, `altair` will become the "natural" type set, then merge and so on, so no point in giving `phase0` special preferential treatment

time: spring cleaning (#3262) Time in the beacon chain is expressed relative to the genesis time - this PR creates a `beacon_time` module that collects helpers and utilities for dealing the time units - the new module does not deal with actual wall time (that's remains in `beacon_clock`). Collecting the time related stuff in one place makes it easier to find, avoids some circular imports and allows more easily identifying the code actually needs wall time to operate. * move genesis-time-related functionality into `spec/beacon_time` * avoid using `chronos.Duration` for time differences - it does not support negative values (such as when something happens earlier than it should) * saturate conversions between `FAR_FUTURE_XXX`, so as to avoid overflows * fix delay reporting in validator client so it uses the expected deadline of the slot, not "closest wall slot" * simplify looping over the slots of an epoch * `compute_start_slot_at_epoch` -> `start_slot` * `compute_epoch_at_slot` -> `epoch` A follow-up PR will (likely) introduce saturating arithmetic for the time units - this is merely code moves, renames and fixing of small bugs.

singe validator key cache Instead of keeping a validator key list per EpochRef, this PR introduces a single shared validator key list in ChainDAG, and cleans up some other ChainDAG and key-related issues.

Store finalized block roots in database (3s startup) (#3320) * Store finalized block roots in database (3s startup) When the chain has finalized a checkpoint, the history from that point onwards becomes linear - this is exploited in `.era` files to allow constant-time by-slot lookups. In the database, we can do the same by storing finalized block roots in a simple sparse table indexed by slot, bringing the two representations closer to each other in terms of conceptual layout and performance. Doing so has a number of interesting effects: * mainnet startup time is improved 3-5x (3s on my laptop) * the _first_ startup might take slightly longer as the new index is being built - ~10s on the same laptop * we no longer rely on the beacon block summaries to load the full dag - this is a lot faster because we no longer have to look up each block by parent root * a collateral benefit is that we no longer need to load the full summaries table into memory - we get the RSS benefits of #3164 without the CPU hit. Other random stuff: * simplify forky block generics * fix withManyWrites multiple evaluation * fix validator key cache not being updated properly in chaindag read-only mode * drop pre-altair summaries from `kvstore` * recreate missing summaries from altair+ blocks as well (in case database has lost some to an involuntary restart) * print database startup timings in chaindag load log * avoid allocating superfluos state at startup * use a recursive sql query to load the summaries of the unfinalized blocks

singe validator key cache Instead of keeping a validator key list per EpochRef, this PR introduces a single shared validator key list in ChainDAG, and cleans up some other ChainDAG and key-related issues. The PR does not introduce the validator key list in the state transition - this is because we batch-check all signatures before entering the spec code, thus the spec code never hits the cache. A future refactor should _probably_ remove the threadvar altogether. There's a few other small fixes in here that make the flow easier to read: * fix `var ChainDAGRef` -> `ChainDAGRef` * fix `var QuarantineRef` -> `QuarantineRef` * consistent `dag` variable name * avoid using threadvar pubkey cache in most cases * better error messages in batch signature checking

time: spring cleaning (#3262) Time in the beacon chain is expressed relative to the genesis time - this PR creates a `beacon_time` module that collects helpers and utilities for dealing the time units - the new module does not deal with actual wall time (that's remains in `beacon_clock`). Collecting the time related stuff in one place makes it easier to find, avoids some circular imports and allows more easily identifying the code actually needs wall time to operate. * move genesis-time-related functionality into `spec/beacon_time` * avoid using `chronos.Duration` for time differences - it does not support negative values (such as when something happens earlier than it should) * saturate conversions between `FAR_FUTURE_XXX`, so as to avoid overflows * fix delay reporting in validator client so it uses the expected deadline of the slot, not "closest wall slot" * simplify looping over the slots of an epoch * `compute_start_slot_at_epoch` -> `start_slot` * `compute_epoch_at_slot` -> `epoch` A follow-up PR will (likely) introduce saturating arithmetic for the time units - this is merely code moves, renames and fixing of small bugs.

Implement split preset/config support (#2710) * Implement split preset/config support This is the initial bulk refactor to introduce runtime config values in a number of places, somewhat replacing the existing mechanism of loading network metadata. It still needs more work, this is the initial refactor that introduces runtime configuration in some of the places that need it. The PR changes the way presets and constants work, to match the spec. In particular, a "preset" now refers to the compile-time configuration while a "cfg" or "RuntimeConfig" is the dynamic part. A single binary can support either mainnet or minimal, but not both. Support for other presets has been removed completely (can be readded, in case there's need). There's a number of outstanding tasks: * `SECONDS_PER_SLOT` still needs fixing * loading custom runtime configs needs redoing * checking constants against YAML file * yeerongpilly support `build/nimbus_beacon_node --network=yeerongpilly --discv5:no --log-level=DEBUG` * load fork epoch from config * fix fork digest sent in status * nicer error string for request failures * fix tools * one more * fixup * fixup * fixup * use "standard" network definition folder in local testnet Files are loaded from their standard locations, including genesis etc, to conform to the format used in the `eth2-networks` repo. * fix launch scripts, allow unknown config values * fix base config of rest test * cleanups * bundle mainnet config using common loader * fix spec links and names * only include supported preset in binary * drop yeerongpilly, add altair-devnet-0, support boot_enr.yaml

Implement split preset/config support (#2710) * Implement split preset/config support This is the initial bulk refactor to introduce runtime config values in a number of places, somewhat replacing the existing mechanism of loading network metadata. It still needs more work, this is the initial refactor that introduces runtime configuration in some of the places that need it. The PR changes the way presets and constants work, to match the spec. In particular, a "preset" now refers to the compile-time configuration while a "cfg" or "RuntimeConfig" is the dynamic part. A single binary can support either mainnet or minimal, but not both. Support for other presets has been removed completely (can be readded, in case there's need). There's a number of outstanding tasks: * `SECONDS_PER_SLOT` still needs fixing * loading custom runtime configs needs redoing * checking constants against YAML file * yeerongpilly support `build/nimbus_beacon_node --network=yeerongpilly --discv5:no --log-level=DEBUG` * load fork epoch from config * fix fork digest sent in status * nicer error string for request failures * fix tools * one more * fixup * fixup * fixup * use "standard" network definition folder in local testnet Files are loaded from their standard locations, including genesis etc, to conform to the format used in the `eth2-networks` repo. * fix launch scripts, allow unknown config values * fix base config of rest test * cleanups * bundle mainnet config using common loader * fix spec links and names * only include supported preset in binary * drop yeerongpilly, add altair-devnet-0, support boot_enr.yaml
