SIP5-Sharding

Overview

This proposal is to bring in the changes in the shardo branch. This change includes the following:

• Adding a sharded L1 scaling solution
• Revamp of P2P block synchronization
• Updating version number to 2.0

The documentation for these changes are in Book of Snowblossom - Braid

Status

These changes have been in testnet and various smaller scale networks for months. It seems to be very stable.

• Testnet - https://test-b.snowblossom.org/ https://test-b.snowblossom.org/static/shard-visual.html
• Shardtest - https://snow-testshard.1209k.com/ https://snow-testshard.1209k.com/static/shard-visual.html

Both of those networks upgraded from a single shard to multiple shards based on load as expected.

Timeline

If approved, the activation height will be set to be about 90 days from the acceptance vote to allow for updates.
