MonsieurNicolas

Current CAP0023 proposal introduces two mechanisms:

• Allows to represent an arbitrary amount of an asset on the ledger
• delay creation/authorization of a trustline

Basically, it allows to

• create an "unspent entry" in the ledger ("initiate a payment") even if the destination doesn't exist or is not authorized yet
• claim one of those "unspent entries" ("complete a payment") as long as the claimant is authorized to do so

Is there a way to extend this mechanism to support UTXOs (which enables "non fungible tokens" at the same time)? First, we need to define what UTXO means in this context.

Symptoms

Horizon will give an error similar to

Gap detected in stellar-core database. Please recreate Horizon DB.

Reasons for this error

mismatched core/Horizon configurations

MonsieurNicolas

workaround to recover from this

This will require rebuilding the ledger for that validator. You will need enough disk space to download/rebuild that ledger.

prod-example-docs.cfg

# This is an example config for setting up a validator.
# see https://www.stellar.org/developers/stellar-core/learn/admin.html
# for how to properly configure your environment

MonsieurNicolas

This release includes changes to the protocol as well as some stability improvements.

As it changes the meta data format, a newer version (XXX or greater) of Horizon is required.

Stability improvements

• Avoid 100% CPU usage when running certain commands (--newhist for example).
• Handshake code in overlay had issue that would lead to peers not able to an error “unexpected MAC”.
• Align publish with network consensus, this avoids potentially publishing bad ledgers in case of corruption.
• Align catchup with network consensus, this avoids having to rely on timing (which may cause significant delays in catchup).
• Properly fail work when spawning a process throws an exception.
