Bumps github.com/ethereum/go-ethereum from 1.9.15 to 1.9.20.

Release notes

Sourced from github.com/ethereum/go-ethereum's releases.

Paragade (v1.9.20)

Geth v1.9.20 is another maintenance release containing bug fixes and security enhancements. This update is recommended for all users.

Please note that reverting to Geth v1.9.19 or prior after upgrading to v1.9.20 is not possible without a resync because the blockchain database layout has changed.

New Features:

• You can now query the Chain ID using GraphQL (#21451)
• The evm command can now appends the TX hash to state transition output files (#21406)

Bug Fixes & Optimizations:

• Blockchain rewinding and chain repair, i.e. using the SetHead operation, now behave correctly in all cases. An extensive test suite for chain repair has been added. (#21409, #21409)
• Discovery DHT bootstrapping now works properly in very small private networks. (#21396)
• Contract code is now stored separately from state tree data in LevelDB. This change will help with future database upgrades. (#21080)
• Two additional metrics counters for blockchain reorgs have been added. (#21420)
• Metrics collection is now lock-free, causing less lock contention among peer connections (#21446, #21470)
• The GetNodeData operation in the eth peer-to-peer protocol now uses the fast-sync bloom filter to speed up request processing. (#21445)
• Importing block data during fast-sync now performs significantly fewer database reads. (#21468)

Build Changes:

• This release is built with the new and shiny Go 1.15 compiler version (#21466)
• The Ubuntu PPA now contains builds for Ubuntu 20.10 Groovy Gorilla. Ubuntu 19.04 Disco Dingo is no longer supported. (#21461)

For a full rundown of the changes please consult the Geth 1.9.20 release milestone

• Ubuntu packages in our Launchpad PPA repository.
• OSX packages in our Homebrew Tap repository.

Red Janey (v1.9.19)

Geth v1.9.19 is our regular biweekly maintenance release. Apart from the numerous bug-fixes however, it also ships a more deterministic transaction sort order during mining (FIFO). The goal is to reduce front-runner spam which abused miner randomness for transactions at the same price level.

• Sort same-priced transactions by arrival time during mining to reduce front-running (#21358).
• Persist the trie read cache on shutdown to speed up warmup time after a reboot (#20391).
• Swap out the block fetcher of les/x to use the same mechanism as eth/6x (#20692).
• Support setting custom HTTP headers on RCP clients e.g. for authentication (#21392).
• Refactor node lifecycle management, merge GraphQL onto HTTP endpoint (#21105).
• Print enode ID of a node too when doing an ENR dump via devp2p (#21270).
• Trim the build paths to avoid leaking builder infos into the binaries (#21374).
