Lead decisions

• confirmed· blockfrostprotocol-parameters

  Epoch history reads Blockfrost epoch parameters on public networks.

  • cardano/gateway/src/query/services/yaci-history.service.ts:1647const url = new URL(`${endpoint}/epochs/${epoch}/parameters`);

• confirmed· cardano-multiplatform-lib-cmltransaction-encoding

  The gateway decodes on-chain transaction bodies it did not build (packet evidence) with CML 6.2.0.

  • cardano/gateway/src/query/services/query.service.ts:313const body = CML.TransactionBody.from_cbor_hex(evidence.txBodyCborHex);

• confirmed· gouroborosblock-encodingera-identitytransaction-encodingstake-pool-registration

  The probabilistic light client decodes Cardano blocks and pool certificates with gouroboros v0.205.4, before Dijkstra block and transaction types.

  • cosmos/cardano-probabilistic-light-client-core/cardano_block.go:137blockType, err := ledger.DetermineBlockType(blockCbor)
  • cosmos/cardano-probabilistic-light-client-core/cardano_block.go:139decodedBlock, decodeErr := ledger.NewBlockFromCbor(blockType, blockCbor)

• confirmed· kupoblock-encodingera-identitytransaction-encoding

  The gateway's Lucid provider reads UTxOs, datums and scripts from Kupo. Kupo cannot index Dijkstra blocks (R2 gap), so its matches stop at the fork.

  • cardano/gateway/src/shared/modules/lucid/lucid.provider.ts:792`${kupoEndpoint}/matches/${queryPredicate}${isAddress ? '' : '/*'}?unspent`,

• confirmed· ogmiosblock-encodingera-identityplutus-languageprotocol-parameterstransaction-encoding

  The gateway follows blocks and reads era summaries through Ogmios, and its Lucid provider submits, evaluates and reads parameters through it.

  • cardano/gateway/src/shared/helpers/time.ts:213sendRequest('nextBlock');
  • cardano/gateway/src/shared/helpers/time.ts:124ogmiosUrl, 'queryLedgerState/eraSummaries', {},
  • cardano/gateway/src/shared/modules/lucid/lucid.provider.ts:456export async function evaluateTxWithOgmiosScriptRefFallback<T>(

• undetermined· cardano-serialization-lib-cslplutus-language

  CSL is used by the bundled demo dApps (address handling and transaction hex decoding); whether they meet PlutusV4 content is not decidable from source.

  • dapps/ibc-swap/client/containers/Swap/index.tsx:21import * as CSL from '@emurgo/cardano-serialization-lib-browser';

• undetermined· cardano-serialization-lib-cslprotocol-parametersstake-pool-registrationtransaction-encoding

  The bundled demo dApps decode transaction hex with CSL; whether they meet Dijkstra bodies is not decidable from source.

  • dapps/ibc-swap/client/containers/Swap/index.tsx:21import * as CSL from '@emurgo/cardano-serialization-lib-browser';

• undetermined· gouroborosconsensus-participationplutus-languageprotocol-parameterstransaction-rules

  Plutus, parameter, consensus and rule surfaces have no identified shipped path; left to execution.

• not-reached· aikenplutus-languageplutus-script-context

  The project compiles its own validators to PlutusV3; existing Plutus versions stay valid after the fork, so only PlutusV4 authoring is blocked.

  • cardano/onchain/aiken.toml:2name = "cardanofoundation/cardano-ibc"

• not-reached· blockfrostera-identity

  Era summaries come from Ogmios, not /network/eras.

  • cardano/gateway/src/shared/helpers/time.ts:124ogmiosUrl, 'queryLedgerState/eraSummaries', {},

• not-reached· cardano-db-syncblock-encodingera-identityprotocol-parametersstake-pool-registrationtransaction-encoding

  The gateway reads chain history from Kupo, Yaci and Blockfrost; db-sync appears only in a comment and in local devnet configuration.

  • cardano/gateway/src/shared/modules/kupo/kupo.service.ts:71// connection/channel id without depending on a db-sync-specific row shape.

• not-reached· cardano-js-sdkprotocol-parameters

  Only @cardano-sdk/crypto is reached outside lucid-evolution (key and hash primitives); parameter-update decoding is in @cardano-sdk/core.

  • cardano/gateway/package-lock.json:928"node_modules/@cardano-sdk/core/node_modules/@cardano-sdk/crypto": {

• not-reached· cardano-multiplatform-lib-cmlblock-encodingera-identityplutus-languageprotocol-parametersstake-pool-registration

  Other CML use builds the gateway's own transactions.

  • cardano/gateway/src/query/services/query.service.ts:313const body = CML.TransactionBody.from_cbor_hex(evidence.txBodyCborHex);

• not-reached· cardano-serialization-lib-cslblock-encoding

  CSL decodes transactions here, not blocks.

  • dapps/ibc-swap/client/containers/Swap/index.tsx:21import * as CSL from '@emurgo/cardano-serialization-lib-browser';

• not-reached· gouroborosnode-to-client-protocol

  Only a CI script opens a node-to-client connection; the shipped light client and relayer do not.

  • scripts/ci/capture-praos-nonce-reference.go:57ouroboros.WithNodeToNode(false), ouroboros.WithChainSyncConfig(chainsync.NewConfig(

• not-reached· koiosera-identityprotocol-parameters

  Koios appears only as a configurable epoch-parameter endpoint in setup tests and a comment; the gateway's epoch history uses Blockfrost-shaped requests.

  • cardano/gateway/src/query/services/local-epoch-stake.ts:11* Like the existing Koios adapter, this trusts the configured node/data source.

• not-reached· lucid-evolutionprotocol-parametersstake-pool-registrationtransaction-encoding

  Builds and submits its own Conway-shaped transactions; nothing Dijkstra-only is decoded.

  • cardano/gateway/package.json:57"@lucid-evolution/lucid": "0.6.5",

• not-reached· meshjs-mesh-sdkplutus-languageprotocol-parametersstake-pool-registrationtransaction-encoding

  Builds and submits its own Conway-shaped transactions; nothing Dijkstra-only is decoded.

  • dapps/ibc-swap/client/package.json:48"@meshsdk/common": "1.9.1",

• not-reached· plutigoplutus-languageplutus-script-context

  plutigo is indirect in the light-client modules with no import.

  • cosmos/cardano-probabilistic-light-client-core/go.mod:24github.com/blinklabs-io/plutigo v0.7.1 // indirect
