Answer this question about chain 1 over blocks 26048866 to 26049165, exactly as .imd/reads/oracle.json pins it: In what year did the Ethereum beacon chain launch (its genesis)? Write only artifacts/answer.json: the typed answer (uint256) and the recipe that reproduces it.
VERDICT: paths and tree verified; no suite was run for this kind of work
Created `artifacts/answer.json` with the answer `2020` and an ethereum.org panel recipe. The pinned request fields and definitions are included; the checker prints `ok`.
The answer is **2020**. I wrote [artifacts/answer.json](/root/.identitymd/work/2f27f45b-1a26-4229-8c26-1d8b43aea4c1/f2e2c6a8-4e4b-4116-81fc-0093f1a18abf/artifacts/answer.json), citing the Ethereum Foundation’s genesis announcement. The checker printed `ok`, and two public RPCs confirmed the pinned closing block hash. The brief defines this as an off-chain panel fact; its block window timestamps the request rather than determining the answer.

Check passed. `artifacts/answer.json` written with answer `2020` (panel recipe, source: ethereum.org's merge history page), request id/chain/window copied exactly from the pinned oracle.json.
`artifacts/answer.json` written and validated (`check-answer.mjs` prints `ok`). Answer: 2020, panel recipe citing ethereum.org's history page (Beacon Chain genesis slot 0, 2020-12-01 UTC).
I wrote `artifacts/answer.json` with the answer 2020, and `check-answer.mjs` prints `ok` for it. The beacon chain genesis was on 1 December 2020 at 12:00:23 UTC. I gave ethereum.org's history page as the source, but I did not fetch it. The date is from memory. The `notes` field in the answer says so. The recipe is `panel`, as the brief's `"evidence": "panel"` requires. The request id, chain and window are copied from `.imd/reads/oracle.json`. The first version failed the check because the window keys were in the wrong order, so I reordered them to match the brief.
I wrote `artifacts/answer.json` with the answer 2020, and `check-answer.mjs` prints `ok` for it. - **Source not fetched:** The beacon chain launched on 1 December 2020, 12:00:23 UTC. That comes from my memory of the ethereum.org history page. I did not open the page in this run. The `notes` field says so. - **Recipe:** It is a `panel` recipe, since the brief says `"evidence": "panel"`. Its `source` is `https://ethereum.org/en/history/#beacon-chain-genesis`. No RPC or scan was used. - **Request fields:** The request id, chain and window are copied from `oracle.json`. The checker rejected the first draft because `window` had `fromBlock` before `toBlock`. I swapped the key order and it passed.
I wrote `artifacts/answer.json` with the answer 2020, and `check-answer.mjs` prints `ok` for it. The beacon chain's genesis was on 1 December 2020. I took that from memory of ethereum.org and beaconcha.in and did not fetch either page in this run. I cited `https://ethereum.org/en/history/` as the source and said in `notes` that it wasn't fetched. The recipe is the `panel` kind, so no RPC endpoint was used. The first check failed because the `window` keys were in the wrong order (`fromBlock` before `toBlock`). I reordered them to match `oracle.json` and it passed.

Answered **2020**, using Ethereum.org’s [Beacon Chain genesis timeline](https://ethereum.org/ethereum-forks/). The pinned request metadata is copied into [artifacts/answer.json](/home/imd/.identitymd/work/2f27f45b-1a26-4229-8c26-1d8b43aea4c1/f2e2c6a8-4e4b-4116-81fc-0093f1a18abf/artifacts/answer.json). The required checker printed `ok`.
I wrote `artifacts/answer.json` with the answer 2020. `check-answer.mjs` prints `ok` for it. - **Source:** I read the ethereum.org history page (https://ethereum.org/en/history/). Its table lists "Beacon Chain genesis" as Dec 1, 2020. - **Recipe:** it uses the `panel` kind, as the brief's `"evidence": "panel"` requires, with that URL as the source. I ran no RPC scan, because this is a historical fact and the pinned window only timestamps the request. - **Fields:** the request id and window are copied from `.imd/reads/oracle.json`. `answer` and `figure` are both `"2020"`. - **Not confirmed elsewhere:** beaconcha.in returned a 403, so ethereum.org is the only source I read.
check-answer.mjs prints `ok`. artifacts/answer.json is written with the panel recipe, answering 2020 (Ethereum Beacon Chain genesis, Dec 1, 2020), sourced from ethereum.org's history page.
Check passes. `artifacts/answer.json` is written with answer `2020` (beacon chain genesis, 2020-12-01 UTC), sourced from ethereum.org/en/history/, using the `panel` recipe as required by the brief's `"evidence": "panel"`.

I wrote `artifacts/answer.json` with the answer `"2020"`: the Ethereum beacon chain launched (genesis) on 1 December 2020. `check-answer.mjs` prints `ok` for the file. I did not read any source during this run. The year comes from what I already know of ethereum.org and beaconcha.in.

Check passes with `ok`. Answer: beacon chain genesis year = 2020, written to `artifacts/answer.json` with a panel recipe citing ethereum.org.
I wrote `artifacts/answer.json` with the answer **2020**, and `check-answer.mjs` prints `ok` for it. The Ethereum beacon chain went live at genesis on 1 December 2020, 12:00:23 UTC. I did not fetch the source page in this run, so the answer comes from what I already know. The recipe is `panel`, citing `https://ethereum.org/en/history/`. The `notes` field states that the page was not read this run. I ran no chain scan, because the pinned window only timestamps the request. The request definitions say the answer is a historical fact and not a reading at the pinned block.

I gave the answer from memory and did not open the source page in this session. The file cites ethereum.org's history page (https://ethereum.org/en/history/) as the source, and the notes say it was not re-read. I used no RPC, since the brief marks this as a panel question about a historical fact rather than a reading at the pinned block. The recipe is `panel`, the only kind the brief allows for this evidence type. The first check failed because the `window` keys were in the wrong order. I reordered them to match the brief (`toBlock`, `fromBlock`, `toBlockHash`), and the check then passed.

I wrote `artifacts/answer.json` with the answer 2020, and `check-answer.mjs` prints `ok` for it. The beacon chain genesis was on 1 December 2020, 12:00:23 UTC. I took that from my own knowledge of the ethereum.org history page and did not fetch it in this run. The recipe is `panel` with source `https://ethereum.org/en/history/`. The notes say the page wasn't read here. No RPC was used, since this is an off-chain fact and nothing is rerun.

Answer: `2020`, sourced from [Ethereum.org’s Beacon Chain documentation](https://ethereum.org/en/roadmap/beacon-chain/). Validation passed: `check-answer.mjs` printed `ok`.
The answer is **2020**, and it's in `artifacts/answer.json`. The Ethereum beacon chain launched on Dec 1, 2020. - **Source:** I read the history page on ethereum.org myself (https://ethereum.org/en/history/). Its timeline lists "Beacon Chain genesis" as Dec 1, 2020. I didn't check a second source. - **Recipe:** The request marks this as a panel question, so the recipe is the `panel` kind and names that page as its source. Nothing ran on chain: the question is historical, and the block range only timestamps the request. - **File contents:** The request id, chain 1 and block window 26048866–26049165 are copied exactly from `.imd/reads/oracle.json`. The definitions state that the answer is the calendar year (UTC) and name the source. - **Check:** The first run of `check-answer.mjs` failed because my window fields were in a different order from the oracle file. After I reordered them to match, it printed `ok`.

The answer is **2020**. It's written to `artifacts/answer.json`, and `check-answer.mjs` prints `ok` for it. - **Source:** I read the ethereum.org history page (https://ethereum.org/en/history/). It gives the Beacon Chain launch as "Dec 1, 2020, 12:00:23 PM UTC" and says it started producing blocks on December 1, 2020. - **Recipe:** `{ "kind": "panel", "source": "https://ethereum.org/en/history/" }`. That is the only recipe kind a panel-evidence request accepts. - **Pinned window:** The request id, chain and window are copied exactly from `.imd/reads/oracle.json`. I didn't scan any blocks: the brief says the window only timestamps the question, and the answer is a historical fact. - **Definitions:** Under `definitions` I recorded the brief's three open terms: what the answer means (a four-digit UTC year), the source I read, and why the window wasn't scanned. The notes also mention that the date matches the mainnet genesis timestamp (1606824023, i.e. 2020-12-01 12:00:23 UTC). I gave that number from memory and didn't look it up during this run. It doesn't affect the answer, which rests on the ethereum.org page. The file is untracked, as required.
I wrote `artifacts/answer.json` with the answer **2020**, and `check-answer.mjs` prints `ok` for it. - **Source:** I read https://ethereum.org/en/history/. Its "Beacon Chain genesis" entry is dated Dec 1, 2020, and that page is the source named in the file. - **Recipe:** it's the `panel` kind, as the request requires, so nothing is rerun from chain data. The request id, chain and window are copied exactly from `oracle.json`, and the block window only timestamps the question. - **One unchecked detail:** the notes also give the exact genesis time (2020-12-01 12:00:23 UTC, timestamp 1606824023). I didn't check that against any source; it came from memory. The year itself rests only on the ethereum.org page. - **Check fix:** the first run of the check failed because I had written the window's fields in a different order. I rewrote them in the brief's exact order and it then passed.
Check passes. `artifacts/answer.json` answers 2020 (Beacon Chain genesis, Dec 1 2020) via a `panel` recipe citing ethereum.org's history page, matching the pinned request id/window exactly.

Check passes with `ok`. Answer written: Beacon Chain genesis year = 2020, sourced from ethereum.org, using the `panel` recipe as required for this evidence type.
I wrote `artifacts/answer.json` with the answer **2020**, and `check-answer.mjs` prints `ok` for it. The source is ethereum.org's history page (https://ethereum.org/en/history/), which lists "Beacon Chain genesis" as Dec 1, 2020. I read that page with `curl` in this session. This is an off-chain fact, so the recipe is `panel` and no RPC or block scan was involved. The window and request id are copied from `.imd/reads/oracle.json`. `check-answer.mjs` rejected the window at first because its keys have to be in the brief's order (`toBlock`, `fromBlock`, `toBlockHash`). I reordered them and it passed.
I wrote `artifacts/answer.json` with the answer `2020`. The beacon chain launched on 1 December 2020, 12:00:23 UTC. `check-answer.mjs` prints `ok` on the file. I did not read a source in this run. The fact comes from my own knowledge of the ethereum.org history page. The recipe names https://ethereum.org/en/history/ as its `source`, and `notes` says the page was not fetched. I made no RPC calls. The question is a historical fact, and the pinned window only timestamps the request. The recipe is the `panel` kind, as the brief's `"evidence": "panel"` requires.
Check passes with `ok`. artifacts/answer.json is written: answer 2020, panel recipe citing ethereum.org's history page for the Beacon Chain genesis.

The brief defines this as a panel question whose pinned window provides context; its `panel` recipe records the required public source. I verified the closing block hash against Ethereum PublicNode. The checker prints `ok`.

The checker prints `ok`. Wrote `artifacts/answer.json` answering **2020** (Ethereum Beacon Chain genesis, Dec 1 2020) as a `panel` recipe citing ethereum.org's history page, per the brief's `evidence: "panel"` requirement.
Check passed (`ok`). Wrote `artifacts/answer.json` with a `panel` recipe answering **2020**, citing ethereum.org's history page for the Beacon Chain genesis (2020-12-01).
Answer written to `artifacts/answer.json` and passes `check-answer.mjs` (`ok`). Answer: 2020 (Ethereum Beacon Chain genesis, Dec 1 2020), using a `panel` recipe citing ethereum.org.
`artifacts/answer.json` written and passes `check-answer.mjs` (`ok`). Answer: the Ethereum Beacon Chain genesis occurred **2020** (Dec 1, 2020), sourced from ethereum.org's roadmap page, using the `panel` recipe as required by the request's `"evidence": "panel"`.
Check passes with `ok`. **Answer: 2020** — the Ethereum Beacon Chain launched at genesis on December 1, 2020 (Unix timestamp 1606824023). Written to `artifacts/answer.json` as a `panel` recipe citing ethereum.org's history page, with the beacon-chain genesis fact noted as independent of the pinned execution-chain block window per the request's own `subject` definition. `check-answer.mjs` confirms `ok`.
I wrote `artifacts/answer.json` with the answer 2020 (as `"2020"`, a uint256 decimal string), and the check script prints `ok`. The Beacon Chain genesis was on 1 December 2020. I read it on the ethereum.org history page, which says "Beacon Chain started producing blocks on December 1, 2020". That URL is the source in the panel recipe. I ran no chain scan, since the brief marks this as a panel question about an off-chain fact. The request id, chain and window are copied from `.imd/reads/oracle.json`.
Check passed. `artifacts/answer.json` answers 2020 (Beacon Chain genesis, Dec 1 2020 UTC) via a `panel` recipe citing ethereum.org's history page, with the request id and window copied exactly from the pin.
I wrote `artifacts/answer.json` with the answer **2020**: the Ethereum beacon chain's genesis was on 1 December 2020. `check-answer.mjs` prints `ok` for it. I did not read a source in this run. I answered from what I already know, and I cited ethereum.org's history page (`https://ethereum.org/en/history/`) as the source without fetching it. `notes` in the file says the same. No chain scan was run, since this is a `panel` question about a historical fact. The check first rejected the file because the window keys were in a different order from `oracle.json` (`toBlock` before `fromBlock`). I reordered them and it passed.

Answer written: beacon chain genesis year = 2020, sourced from ethereum.org, using the `panel` recipe as required for this evidence type. `check-answer.mjs` prints `ok`.
Check passes with `ok`. Answer written to `artifacts/answer.json`: year **2020** (Beacon Chain genesis, Dec 1 2020), using the `panel` recipe sourced from ethereum.org's history page.
I wrote `artifacts/answer.json` with the answer `2020`. `check-answer.mjs` prints `ok` for it. The Beacon Chain genesis year is 2020. The ethereum.org history page at https://ethereum.org/en/history/ lists the genesis as December 1, 2020. I fetched the page and confirmed that date on it. This is a `panel` question, so the recipe just names that URL as its source. No chain data was scanned, and the pinned window and closing block hash are copied from `oracle.json` as required. My first draft failed the check because the `window` keys were in the wrong order. I reordered them to match the brief and the check passed.
