Show total price when topping up rofl machine (#624) ±46 by abukosek @ 2025-10-10.

Closes #612.

feat(build/rofl): Bump rofl-containers to v0.8.1 (#625) ±2 by kostko @ 2025-10-09.
cmd/account/show: add balance alias (#630) ±2 by csillag @ 2025-10-16.

This makes it possible to execute oasis account balance and get the same result as oasis account show.

The goal of this change is to get our CLI tool more inline with expectations (hallucinations) of AI coding tools, by making it more similar to other tools on the market, in order to decrease friction for new developers.

feat(build/rofl): Bump rofl-containers to v0.8.2 (#636) ±2 by ptrus @ 2025-10-28.
1 new releases of cli were made this month: In total, 6 pull requests were merged in October.

Network Updates

Mainnet highlights

[2025-10-29] am3lody:

We have released Oasis Core 25.6 for MAINNET.

Key highlights include: ➡️ Pruning of runtime state was sped up quite significantly by increasing the default BadgerDB block cache size to 256 MiB.
➡️ The runtime host handler was fixed to fetch the light block from other nodes in the network in case block results for the requested height are unavailable.
➡️ CometBFT was fixed to support pruning of consensus block store during initial block sync, reducing overall disk usage.
➡️ The runtime transaction pool now supports multiple transactions from the same sender for runtimes that allow future nonces and multiple sender transactions per block.

NOTE: If you encounter issues with paratimes after upgrading, try restarting your node.

Visit the changelog (https://github.com/oasisprotocol/oasis-core/blob/v25.6/CHANGELOG.md) to view all changes. The upgrade is non-breaking and can be performed at any time by replacing the oasis-node binary and restarting your node. All node operators on MAINNET are encouraged to upgrade. For more information and links to releases, see the updated MAINNET network parameters (https://docs.oasis.io/node/network/mainnet/). Thanks!

The number of daily transactions on Sapphire Mainnet fluctuated between 6,285 and 14,919. The monthly average in October was 12,082 transactions per day and was 9% lower compared to the last month (13,264 transactions). The daily maximum was 14,919 transactions on 8 October (compared to 23,460 the last month on 28 September).

Increase the max backoff interval above 12 min to recover from potential Let's Encrypt authorization failure limits.
Otherwise, certificate provisioning can get stuck in an endless failure loop due to retrying too quickly.

{"err":"API error: too many failed authorizations (5) for \"ethrpc.rofl.cloud\" in the last 1h0m0s, retry after 2025-10-15 12:44:25 UTC: see https://letsencrypt.org/docs/rate-limits/#authorization-failures-per-hostname-per-account (urn:ietf:params:acme:error:rateLimited)","level":"error","module":"runtime/serverd/cert-provisioner","msg":"failed to provision certificate","sni":"ethrpc.rofl.cloud","ts":"2025-10-15T12:42:10.531241105Z"}

An alternative would be to manually handle the Retry-After value from the error or response header, but the backoff-based approach seemed simpler since it doesnt look like instant-acme provides this nicely.

go/runtime/txpool: Add support for multiple transactions per sender (#6280) ±3098 by peternose @ 2025-10-10.

The schedule queue was changed to support multiple transactions per sender.

The queue uses virtual transaction blocks to improve priority. For example, if a sender sends a transaction A with sequence number 1 and priority 0 and transaction B with sequence number 2 and priority 100, both transactions are put into a virtual block [A, B] with an average priority 50.

The main queue was changed to support multiple transactions per sender.

go/runtime/txpool: Add support for multiple transactions per sender

go/common/node/node: Refactor code (#6369) ±456 by peternose @ 2025-10-27.

Minor fixes found along the way.

go/oasis-node/cmd/storage: Add command that flattens consensus dbs (#6311) ±240 by martintomazic @ 2025-10-20.

Part of #6309.

This command has been thoroughly tested and is able to immediately reclaim all the disk space even if enabling pruning late.

Unfortunately, there is a known corner case where disk space used during the peak of the compaction may be double the original size - see. It is for this reason that I suggest to release this as experimental command.

Performance:
Currently it takes less then 1h to compact all the consensus databases (with all the state/blocks from the genesis) on my 2TB playground.

I haven't observed that increasing number of the Flatten workers would increase the overall disk usage during the peak of the compaction (as warned by the badger cli documentation). How about adding this as an optional parameter?

This way users with spare disk space could e.g. configure it to use 8 workers, and thus speed-up compaction significantly. 3-5 times as from my experiments.

We may also explore the impact of increasing BlockCacheSize...

Follow-up
Given that I was testing this only on the consensus DB instances, I suggest to add compaction of the runtime DB instances as a follow-up. The testing there is also complicated as runtime state pruning is very slow, making it hard to prepare realistic samples.

I suggest the following order of follow-ups:

  1. #6341 (only consensus)
  2. Enable compaction for the runtime databases.
  3. E2e test for the compact command.
  4. Enable offline pruning for the runtime databases.

CHANGELOG:

go/oasis-node: Add new command for compacting consensus databases
A new experimental command `oasis-node storage compact-experimental` was added.
The command triggers manual compactions for all the consensus databases. This way node operators can forcefuly release disk space if enabling late pruning.

Changelog 21.0.2 (#6378) ±37 by ptrus @ 2025-10-31.

Prepare a release for #6350

This is the last backport release we are missing for archive nodes.

Note that the release will be done manually, since the outdated CI jobs on the stable/21.0.x branches are most likely not working anymore.

Similar as it was done for https://github.com/oasisprotocol/oasis-core/releases/tag/v20.12.8 and https://github.com/oasisprotocol/oasis-core/releases/tag/v20.10.2

We will publish/make the release public at a later date, right before we release a new oasis-core version so that these release wont be at the top.

CHANGELOG:

go/consensus/cometbft/full: Error if light block cannot be constructed
Returning an error instead of an empty light block when block results for the requested height are unavailable will cause the runtime host handler to fetch the light block from other nodes in the network.

go: Bump default block cache size of NodeDB badger instances to 256 MiB (#6339) ±12 by martintomazic @ 2025-10-08.

As from the experiments, increasing block cache size significantly increases the pruning speed of the runtime state (see).

Looking at the badgerDB documentation, it is recommended to use cache if using compression. The current default value is 256 MB, thus bumping to it from existing 64 MB.

Finally, given that we are highly data intensive application we may set it to even more, e.g. 1 GB.

Might be also a good idea to bump cometbft managed databases (i.e. blockstore, state, evidence) albeit feels wasteful for the evidence, and currently there is no granularity. Given we don't have performance bottlenecks there for now we could keep it as is.

Will add a changelog once we align on the final size and scope of the changes.

CHANGELOG:

go/NodeDB: Bump default BadgerDB block cache size to 256 MiB
Previously default value for NodeDB instances was 64 MiB. By bumping it we speed-up pruning of runtime state quite significantly.

go/oasis-test-runner/scenario: Apply the updated policy (#6379) ±8 by peternose @ 2025-10-30.

Test dynamic-update halts at waiting for key manager nodes to initialize as key manager enclave requires key manager policy to be set during initialization (see this build as an example). To fix this, we need to apply the pending policy by transitioning to the next epoch.

Since this test is not included in the basic SGX tests, it failed only on master when full SGX test suite was run.

go/p2p: Add observer nodes to the target set of registered nodes (#6343) ±7 by martintomazic @ 2025-10-08.

Closes #6342.

Not sure this will have much impact as these nodes were likely found via discovery (seed nodes, or possibly via libp2p if already connected with a given peer due to other protocol)...

Bump CometBFT to 0.37.16-oasis1 (#6358) ±5 by kostko @ 2025-10-15.

CHANGELOG:

Bump CometBFT to 0.37.16-oasis1

go/runtime/manager: Fix temporary bundle path (#6375) ±3 by ptrus @ 2025-10-29.

root.Name() already returns the full path.

This might have caused some issues on the testnet provider after node upgrade:

 net.oasis.error: module: unknown code: 1 message: failed to open bundle: runtime/bundle: failed to open bundle: open /node/data/runtimes/tmp/bundles/node/data/runtimes/tmp/bundles/d8f764ac129c15684291a35ce606b0dbf6aeebd6205dbf2e3a69d41994b57598/instance-00000000000003a9: no such file or directory

root.Name() test:

package main

import (
	"fmt"
	"os"
)

func main() {
	_ = os.MkdirAll("/tmp/x/y", 0o755)

	root, err := os.OpenRoot("/tmp/x/y")
	if err != nil {
		panic(err)
	}
	defer root.Close()

	fmt.Println("root.Name() =", root.Name())
}

// outputs: root.Name() = /tmp/x/y

go/runtime/manager: Fix temporary bundle path
