SC_CODE string "/* gt_service.bas -- R32 mechanism M2 "useful service + bounded fee rebate + miner boost", DVM-BASIC. A notary service: Notarize(doc) records a document digest (first writer wins) for a fee. rho percent of every fee goes to the epoch's rebate pool, the rest to the treasury. After the epoch ends each fee payer claims pool * weight / total weight. Weight = fee, or fee * (100 + boost) / 100 while the payer keeps >= minmat MAT (the M1 token, set by SetMAT) staked here. No-wash condition (enforced by SetParams): rho * (100 + boost) <= 10000, so a payer's rebate can never exceed the fee it paid unless other payers' fees or a sponsor subsidy fund it. A sponsor may add DERO to the current epoch's pool (Sponsor); that subsidy is competed for by fee payers (see the child rft). No payout is funded by a later participant's deposit: epoch e's pool is closed when e ends. */ Function Initialize() Uint64 10 STORE("owner", SIGNER()) 20 STORE("fee", 1000) 30 STORE("rho", 50) 40 STORE("boost", 100) 50 STORE("epoch", 100) 60 STORE("minmat", 100) 70 STORE("mat", "") 80 STORE("frozen", 0) 90 STORE("treasury", 0) 100 STORE("ndocs", 0) 110 RETURN 0 End Function Function SetParams(fee Uint64, rho Uint64, boost Uint64, epoch Uint64, minmat Uint64) Uint64 10 IF LOAD("owner") != SIGNER() THEN GOTO 900 20 IF LOAD("frozen") != 0 THEN GOTO 900 30 IF fee == 0 || epoch == 0 THEN GOTO 900 40 IF rho > 100 THEN GOTO 900 50 IF rho * (100 + boost) > 10000 THEN GOTO 900 60 STORE("fee", fee) 70 STORE("rho", rho) 80 STORE("boost", boost) 90 STORE("epoch", epoch) 100 STORE("minmat", minmat) 110 RETURN 0 900 RETURN 1 End Function Function SetMAT(scidhex String) Uint64 10 IF LOAD("owner") != SIGNER() THEN GOTO 900 20 IF LOAD("frozen") != 0 THEN GOTO 900 30 IF STRLEN(scidhex) != 64 THEN GOTO 900 40 STORE("mat", HEXDECODE(scidhex)) 50 RETURN 0 900 RETURN 1 End Function Function Freeze() Uint64 10 IF LOAD("owner") != SIGNER() THEN GOTO 900 20 STORE("frozen", 1) 30 RETURN 0 900 RETURN 1 End Function Function boosted(a String) Uint64 10 IF EXISTS("ms" + a) == 0 THEN GOTO 40 20 IF LOAD("ms" + a) < LOAD("minmat") THEN GOTO 40 30 RETURN 1 40 RETURN 0 End Function Function Notarize(doc String) Uint64 10 DIM e, f, w, r as Uint64 20 DIM k as String 30 IF LOAD("frozen") == 0 THEN GOTO 900 40 IF IS_ADDRESS_VALID(SIGNER()) == 0 THEN GOTO 900 50 LET f = LOAD("fee") 60 IF DEROVALUE() != f THEN GOTO 900 70 IF STRLEN(doc) == 0 || STRLEN(doc) > 64 THEN GOTO 900 80 IF EXISTS("d" + doc) == 1 THEN GOTO 900 90 STORE("d" + doc, BLOCK_HEIGHT()) 100 STORE("ndocs", LOAD("ndocs") + 1) 110 LET e = BLOCK_HEIGHT() / LOAD("epoch") 120 LET r = f * LOAD("rho") / 100 130 LET w = f 140 IF boosted(SIGNER()) == 0 THEN GOTO 160 150 LET w = f * (100 + LOAD("boost")) / 100 160 LET k = ITOA(e) + ":" + SIGNER() 170 IF EXISTS("w" + k) == 1 THEN GOTO 190 180 STORE("w" + k, 0) 190 STORE("w" + k, LOAD("w" + k) + w) 200 IF EXISTS("W" + ITOA(e)) == 1 THEN GOTO 230 210 STORE("W" + ITOA(e), 0) 220 STORE("P" + ITOA(e), 0) 230 STORE("W" + ITOA(e), LOAD("W" + ITOA(e)) + w) 240 STORE("P" + ITOA(e), LOAD("P" + ITOA(e)) + r) 250 STORE("treasury", LOAD("treasury") + f - r) 260 IF EXISTS("ml" + SIGNER()) == 0 THEN GOTO 290 270 IF LOAD("ml" + SIGNER()) > e THEN GOTO 290 280 STORE("ml" + SIGNER(), e) 290 RETURN 0 900 RETURN 1 End Function Function Sponsor() Uint64 10 DIM e as Uint64 20 IF DEROVALUE() == 0 THEN GOTO 900 30 LET e = BLOCK_HEIGHT() / LOAD("epoch") 40 IF EXISTS("P" + ITOA(e)) == 1 THEN GOTO 70 50 STORE("P" + ITOA(e), 0) 60 STORE("W" + ITOA(e), 0) 70 STORE("P" + ITOA(e), LOAD("P" + ITOA(e)) + DEROVALUE()) 80 RETURN 0 900 RETURN 1 End Function Function StakeMAT() Uint64 10 DIM v, s as Uint64 20 IF STRLEN(LOAD("mat")) != 32 THEN GOTO 900 30 IF IS_ADDRESS_VALID(SIGNER()) == 0 THEN GOTO 900 40 LET v = ASSETVALUE(LOAD("mat")) 50 IF v == 0 THEN GOTO 900 60 LET s = 0 70 IF EXISTS("ms" + SIGNER()) == 0 THEN GOTO 90 80 LET s = LOAD("ms" + SIGNER()) 90 STORE("ms" + SIGNER(), s + v) 100 STORE("ml" + SIGNER(), BLOCK_HEIGHT() / LOAD("epoch")) 110 RETURN 0 900 RETURN 1 End Function Function UnstakeMAT(amount Uint64) Uint64 10 IF EXISTS("ms" + SIGNER()) == 0 THEN GOTO 900 20 IF BLOCK_HEIGHT() / LOAD("epoch") <= LOAD("ml" + SIGNER()) THEN GOTO 900 30 IF amount == 0 || amount > LOAD("ms" + SIGNER()) THEN GOTO 900 40 STORE("ms" + SIGNER(), LOAD("ms" + SIGNER()) - amount) 50 SEND_ASSET_TO_ADDRESS(SIGNER(), amount, LOAD("mat")) 60 RETURN 0 900 RETURN 1 End Function Function ClaimRebate(e Uint64) Uint64 10 DIM k as String 20 DIM pay as Uint64 30 IF (e + 1) * LOAD("epoch") > BLOCK_HEIGHT() THEN GOTO 900 40 LET k = ITOA(e) + ":" + SIGNER() 50 IF EXISTS("w" + k) == 0 THEN GOTO 900 60 IF EXISTS("z" + k) == 1 THEN GOTO 900 70 IF LOAD("W" + ITOA(e)) == 0 THEN GOTO 900 80 LET pay = LOAD("P" + ITOA(e)) * LOAD("w" + k) / LOAD("W" + ITOA(e)) 90 STORE("z" + k, 1) 100 SEND_DERO_TO_ADDRESS(SIGNER(), pay) 110 RETURN 0 900 RETURN 1 End Function Function WithdrawTreasury(amount Uint64) Uint64 10 IF LOAD("owner") != SIGNER() THEN GOTO 900 20 IF amount == 0 || amount > LOAD("treasury") THEN GOTO 900 30 STORE("treasury", LOAD("treasury") - amount) 40 SEND_DERO_TO_ADDRESS(SIGNER(), amount) 50 RETURN 0 900 RETURN 1 End Function "
