lightclient	bbfb1e4008	all: add support for EIP-2718, EIP-2930 transactions (#21502 ) This adds support for EIP-2718 typed transactions as well as EIP-2930 access list transactions (tx type 1). These EIPs are scheduled for the Berlin fork. There very few changes to existing APIs in core/types, and several new APIs to deal with access list transactions. In particular, there are two new constructor functions for transactions: types.NewTx and types.SignNewTx. Since the canonical encoding of typed transactions is not RLP-compatible, Transaction now has new methods for encoding and decoding: MarshalBinary and UnmarshalBinary. The existing EIP-155 signer does not support the new transaction types. All code dealing with transaction signatures should be updated to use the newer EIP-2930 signer. To make this easier for future updates, we have added new constructor functions for types.Signer: types.LatestSigner and types.LatestSignerForChainID. This change also adds support for the YoloV3 testnet.

gary rong	61270e5e1c	eth/gasprice: lighter gas price oracle for light client (#20409 ) This PR reduces the bandwidth used by the light client to compute the recommended gas price. The current mechanism for suggesting the price is: - retrieve recent 20 blocks - get the lowest gas price of these blocks - sort the price array and return the middle(60%) one This works for full nodes, which have all blocks available locally. However, this is very expensive for the light client because the light client needs to retrieve block bodies from the network. The PR changes the default options for light client. With the new config, the light client only retrieves the two latest blocks, but in order to collect more sample transactions, the 3 lowest prices are collected from each block. This PR also changes the behavior for empty blocks. If the block is empty, the lastest price is reused for sampling.	5 years ago

all: add support for EIP-2718, EIP-2930 transactions (#21502 )

This adds support for EIP-2718 typed transactions as well as EIP-2930
access list transactions (tx type 1). These EIPs are scheduled for the
Berlin fork.

There very few changes to existing APIs in core/types, and several new APIs
to deal with access list transactions. In particular, there are two new
constructor functions for transactions: types.NewTx and types.SignNewTx.
Since the canonical encoding of typed transactions is not RLP-compatible,
Transaction now has new methods for encoding and decoding: MarshalBinary
and UnmarshalBinary.

The existing EIP-155 signer does not support the new transaction types.
All code dealing with transaction signatures should be updated to use the
newer EIP-2930 signer. To make this easier for future updates, we have
added new constructor functions for types.Signer: types.LatestSigner and
types.LatestSignerForChainID. 

This change also adds support for the YoloV3 testnet.

eth/gasprice: lighter gas price oracle for light client (#20409 )

This PR reduces the bandwidth used by the light client to compute the
recommended gas price. The current mechanism for suggesting the price is:

- retrieve recent 20 blocks
- get the lowest gas price of these blocks
- sort the price array and return the middle(60%) one

This works for full nodes, which have all blocks available locally.
However, this is very expensive for the light client because the light
client needs to retrieve block bodies from the network.

The PR changes the default options for light client. With the new config,
the light client only retrieves the two latest blocks, but in order to
collect more sample transactions, the 3 lowest prices are collected from
each block.

This PR also changes the behavior for empty blocks. If the block is empty,
the lastest price is reused for sampling.
