Every source file in this repository carries SPDX-License-Identifier: Apache-2.0,
and the README has always said Apache 2.0. The LICENSE file said MIT. It was the
only thing in the repository that disagreed, and it was wrong.
This code derives from Hyperledger Besu, which is Apache 2.0. Several files sit in
Besu's own packages because that is where the client loads them from. Publishing
that under MIT was not a choice we were free to make, and it is not one we made
knowingly.
The LICENSE file now contains the Apache 2.0 text as published by the Apache
Software Foundation, byte for byte (sha256 cfc7749b96f63bd31c3c42b5c471bf756814053e847c10f3eb003417bc523d30).
NOTICE records the derivation from Besu.
Nothing about the terms these files were offered under has changed: the file
headers governed before this commit and govern after it. The correction is
recorded in the README rather than made silently, because a licence is the one
thing in a repository a reader should not have to verify.
