Constants ¶
const EarliestEvmTs = 1438269971
EarliestEvmTs - The timestamp of the first Ethereum block in summer 2015 was this value. Since Ethereum was the first EVM based blockchain, all other EVM based block chains have timestamps after this. We can use this fact to distinguish between block numbers and timestamps on the command line (any number in a block range smaller than this is a blockNumber, anything larger than this is a timestamp). This breaks when the block number gets larger than 1,4 billion, which may happen when the chain shards, but not until then.

Functions ¶
func FormattedCode ¶
func FormattedHash ¶
func GetTestChain ¶
func GetTestChain() string
GetTestChain does not get customized per chain. We can only test against mainnet currently
func IsClientErigon ¶
IsClientErigon checks if `version` looks like Erigon
func IsPermitted ¶
func IsPermitted() bool
func IsServerWriter ¶
IsServerWriter tries to cast `w` into `http.ResponseWriter` and returns true if the cast was successful
func IterateOverMap ¶
func IterateOverMap[Key comparable, Value any](ctx context.Context, errorChan chan error, target map[Key]Value, step stepFunc[Key, Value])
IterateOverMap distributes batches of `target` items to a pool of goroutines which execute `step` for every `target` item. Use benchmarks to make sure that concurrent iteration is faster than synchronous one.
func LowerIfHex ¶
func MakeFirstLowerCase ¶
func MakeFirstUpperCase ¶
func OpenBrowser ¶
func OpenBrowser(url string)
func StripComments ¶
