The release is aimed to reduce costs on hosting of Blockscout. It can significantly reduce the size (up to 1Tb*!) of the DB table public.internal_transactions for Parity Ethereum / Nethermind driven Blockscout by ignoring to store the first trace of tx but still getting error and init code from it. And now Raw trace page before showing the traces gets the first trace from the archive node since Blockscout doesn't store the first trace any more.

*in case of Etherum Mainnet

Note 1: Ignoring of transactions' first traces takes place only in case of Parity/Nethermind archive nodes (ETHEREUM_JSONRPC_VARIANT=parity)

Note 2: though, this update prevents to store the 1st trace for new transactions, at the same time it doesn't remove already existing first traces. In order to remove them after installation anyone can safely run this deletion command on the DB:

DELETE FROM public.internal_transactions WHERE index = 0;

Do it only if you use Parity/Nethermind archive nodes

Features

• #3013, #3026, #3031 - Raw trace of transaction on-demand
• #3000 - Get rid of storing of first trace for all types of transactions for Parity variant
• #2875 - Save contract code from Parity genesis file

block_hash indexing approach is introduced

This release contains a major change among other changes, namely migration to block_hash indexing approach. What does it mean? It means that in order to fetch internal transactions, token transfers and logs from the blocks' transactions Blockscout will no longer lean on block number, but it will utilize block hash instead. It is more robust and eliminates possible inconsistencies in the Blockscout DB since block hash is unique whereas several blocks could have the same number on the chains split.

Due to migration to the new block_hash approach, this release also contains DB migrations to add a new column block_hash and block_index to corresponding tables and filling it. Usually, those tables are the biggest in the DB and depending on the capacity of the chain could consist of millions or even hundreds of millions of records. This circumstance could cause a long time execution of migration. Also, before running migration, it is better to switch off the application to decrease the loading on the DB. So, please, notify your users about downtime in the explorer until the migration is finished.
