Etrog (fork.7)

ChangeLog

Precompiled

• add support for the following precompiled smart contracts
  • sha256
  • modexp
  • ecadd
  • ecmul
  • ecpairing

L1InfoTree

• merkle tree that contains historical data
• saved in the smart contracts
• each leaf contains the following parameters:
  • ger: global exit root
  • blockHashL1: blockHash of the L1 network
  • minTimestamp: minimum timestamp

changeL2Block transaction

• add parsing and processing for changeL2Block marker in the batch data
• allows to change L2Block inside a batch
• format:

fields: [type | deltaTimestamp | indexL1InfoTree ]
bytes:  [  1  |       4        |         4       ]

• where
  • type: transaction type to allow differentiate between preEIP155 and legacy transactions
  • deltaTimestamp: time to add to previous block in order to compute the current block timestamp
  • indexL1InfoTree: leaf index in the l1InfoTree. The index will determine the parameters to insert into L2
• leaf data is verified through smtVerify function against the L1InfoRoot (coming from the smart contracts)

BlockInfoTree

• Add merkle-tree to include all the block data while the L2 Block is being processed
  • allow to verify data returned by the RPC

Virtual counters

• modify tooling and test scripts to support virtual counters

What's Changed

• Develop etrog by @krlosMata in #319
• Feature/vcounters 2 by @ignasirv in #321
• fork 7 by @krlosMata in #325
