DEPRECATED - Eth2 data availability sampling - Testground plan
DEPRECATED
My view on Data Availability Sampling has changed, exploring UDP (discv5 based) instead of TCP (gossipsub based) sampling looks more promising.
Eth2 Data Availability Sampling
This repository is a test plan to import into Testground. It tests the viability of various networking ideas for Phase 1 of Eth2.
DAS experiment
Background:
- Original write-up of Vitalik with different approaches
- Expansion on approach 2 by protolambda, using gossip subnets
The idea is to implement a proof of concept in Go, and run it on Testground with different parameters. Work in progress, highly experimental
DAS spec
A draft of the phase 1 specification can be found in the ./spec folder.
This includes:
- How sampling is organized
- How validators run DAS
- How to deal with points of data
- The network spec for shards and DAS
The eth2node package
A mock Eth2 node with just the Phase 1 DAS functionality (sampling, networking, propagation, validation, processing), and instrumentation for gossip tests.
Misc. configurables
Not part of the DAS spec, but for testing purposes:

peers | How many peers to maintain for hi-water |
SHARD_COUNT |
64 |
shards | Number of shards |
SECONDS_PER_SLOT |
12 |
seconds | Number of seconds in each slot |
VALIDATOR_COUNT |
150000 |
validators | Number of active validators |
