| Splice | Canton | DAML SDK | Protocol | LF Default | LF Available |
|---|---|---|---|---|---|
| 0.5.4 | 3.4.9 | 3.4.9 | PV34 | 2.1* | 2.2 (verified) |
| 0.5.3 | 3.4.8 | 3.4.8 | PV34 | 2.1* | 2.2 |
| 0.4.x | 3.3.x | 3.3.x | PV33 | 2.1 | 2.1 |
*Open-source Splice 0.5.4 ships with SDK snapshot 3.3.0-snapshot.20250502 (pre-dates LF 2.2). LF 2.2 was added to the SDK on 2025-10-03. Updating to SDK 3.4.9 enables LF 2.2 builds.
Key Configuration Files
| Purpose | Repo | File |
|---|---|---|
| LF version definitions | daml | sdk/daml-lf/language/.../LanguageVersion.scala |
| damlc target validation | daml | sdk/compiler/damlc/lib/DA/Cli/Options.hs |
| Canton version | canton | VERSION |
| Built-in DARs | canton | community/common/src/main/daml/ |
| Splice LF config | splice | project/CantonDependencies.scala |
| Package targets | splice | daml/*/daml.yaml |
| Docker builds | splice | cluster/images/*/Dockerfile |
Splice LF config (project/CantonDependencies.scala):
val daml_language_versions = Seq("2.1") // ← LF target; change to "2.2" for upgrade
val daml_compiler_version = sys.env("DAML_COMPILER_VERSION")Package ID Derivation
Package IDs are cryptographic hashes of: source content + LF version (--target) + SDK/stdlib version + dependency package IDs.
Changing LF version = different package IDs = incompatible packages. Canton validates that upgraded packages use equal or newer LF version; mixing LF versions on the same ledger causes validation failures.
Enterprise vs Community Canton
| Feature | Enterprise | Community |
|---|---|---|
| Transaction processing | Parallel | Sequential |
| Database | PostgreSQL, Oracle | PostgreSQL only |
| HA Domain | Supported | Embedded only |
| Pruning | Full | Limited |
Build Commands
# Community Canton participant
cd canton && sbt "community/app/assembly"
# Output: community/app/target/scala-2.13/canton-community.jar
# Splice applications (requires DAML_COMPILER_VERSION env var)
cd decentralized-canton-sync && sbt compileUpgrading to LF 2.2 (Verified with SDK 3.4.9)
1. project/CantonDependencies.scala: val daml_language_versions = Seq("2.2") 2. nix/daml-compiler-sources.json: { "version": "3.4.9" } 3. All daml/*/daml.yaml: set sdk-version: 3.4.9 and --target=2.2 4. Remove -Wno-ledger-time-is-alpha from all daml.yaml files (not in SDK 3.4.9) 5. Build: daml build -p daml/splice-util && daml build -p daml/splice-amulet
Community-built DARs have identical package IDs to enterprise at the same LF version (verified 2025-12-24).
Troubleshooting
"Unknown Daml-LF version: 2.2": damlc binary doesn't support 2.2. Check daml damlc --help for supported targets; upgrade to SDK 3.4.9.
Package ID mismatch: different --target values between builds. Check: unzip -p package.dar META-INF/MANIFEST.MF | grep Sdk-Version
Upgrade validation failed: swapping enterprise (LF 2.2) with community (LF 2.1) packages. Use DAR injection to maintain LF 2.2 compatibility.
